    12-8-2016 Counts are low, as well as flush. Approximately 2-3 weeks post a regional application of Malathion. Discussion for the next application is for the Dormant application of a Pyrethroid in January.

    Contribution by Steve Farr

    12/1/16 Counts are finally down. Been a while since the counts were as low or lower for the same time of year, looking at the yearly comparison tab on the bottom right side of the report. This is approximately 2-3 weeks post a regional application of Malathion, mostly done by air. Flush is significantly lower than last year at the same time.

    Discussion for the next regional application is early January with Danitol.

    Contribution by Steve Farr

    11/1/16 Counts are down, this is approximately 1-2 weeks post an Actara application, by air and ground.

    Discussion for the next regional application, and possibly the last for 2016 is an O.P. material to start mid to late November

    Contribution by Steve Farr

    8/30/16 Counts are down. There will be a regional application starting Tuesday September 6th. Going with an Organophosphate material. Jerry Wise will be in this area using Chlorpyrifos. Total cost approx. 17.00/acre. If interested reply to all or call Jerry 334-898-7772

    Contribution by Steve Farr

    8/18/16 Counts are low, but higher than normal for this time of year when comparing the last 5 years of scouting, on the bottom right tab "yearly comparison". The blocks with high counts are in the process of being sprayed with Abermectin and Actara, with the second summer oil spray.

    The next regional application being discussed is to use an
    Organophosphate material in early September.

    Contribution by Steve Farr

    8/3/16 Counts are rising. Approximately 3 weeks post the Organophosphate application. Most growers are starting the second summer oil sprays with a neonics and/or an abermectin miticide.

    Next regional application being discussed is early September.

    Contribution by Steve Farr

    6/20/16 Counts continue to be high, higher for this time of year than the previous 4 years. The summary tab, bottom right shows the picture. This is about 3 weeks post the Dimethoate or Malathion applied by air or ground. Generally most are now going with summer oil, nutritionals, copper, and an insecticide. We are using Movento and Baythroid in most areas.

    The next regional application will be in early to mid-July with an Organophosphate material.

    Contribution by Steve Farr

    5/17/16 Counts are high, like most of the areas in the state. We have just finished a post-bloom spray with Neonics and Agrimek this week. With all the work towards spraying Antibiotics and PFD, there has been very little coordinated efforts for CHEMA sprays the last three months, and has something to do with the high psyllids counts across the state.

    As has been discussed the next CHMA spray is with an Organophosphate application mid to late May, after the Valencia crop is harvested. Jeff Summersill will be starting in this area this weekend with an aerial Dimethoate application for approx. $11.75/acre. Dimethoate has been one of the better and more economical applications. As usual, it is all about the acreage being sprayed at the SAME time. CHMA sprays are going to be less available this year and growers might/should consider to take advantage of them when they can.

    We are a LONG ways from understanding how to effectively use the antibiotics, but most of the current information tells us we NEED to continue with these coordinated efforts towards managing the psyllid. If interested reply to all or call Jeff Summersill 561-722-4502

    5/12/16  Counts are still very high.  Should finish a post-bloom spray with Neonics and Agrimek this week.  With all the work towards spraying Antibiotics and PFD, there has been very little coordinated efforts for CHMA sprays the last three months, and has something to do with the high psyllids counts across the state.

    Contribution by Steve Farr

    4/12/16 Psyllid counts are at an all-time high. We are seeing this in all locations. About ½ of this area had Sivanto put out with antibiotics the last two weeks and the other half is getting Danitol now. Bees and bloom are basically gone. Most growers are working towards a pyrethroid with their Antibiotic sprays now.

    Discussion for the next spray, historical Post-Bloom spray is to go with a neonic. These are economical and have had some success, will also help with leaf minors.

    The next large regional application being discussed is an Organophosphate material to start after the harvest is completed, whenever that might be, but more than likely sometime in mid to late May.

    Contribution by Steve Farr

    1/20/16 Counts are lower. About 80% of this area has been completed with Danitol by ground the last two weeks.

    Discussion for February is to use another pyrethroid, Baythroid was used last year. Per IFAS, during the dormant time of year, the issues with going back to back with same chemistry materials is not as big of a concern.

    Depending on bloom and PFD concerns, as well as nutritional needs, the aerial or ground application decision will have to be made then.

    Contribution by Steve Farr

    1/11/16 Counts are finally low, this is approximately 4 weeks post the Imidan application done by air and ground, depending on the block.

    We have started a ground application of Danitol. Added other materials and with harvesting, aerial application would have been difficult.

    12/18/15  Counts are low but high for this time of year, we see this in most areas with this area having 74% flush currently and last year at the same time with the same trees, 26%
    This is approximately 1-2 weeks post an Organophosphate regional application of Imidan by air or Malathion by ground, pending the block and location. 

    The next regional application being discussed is a Pyrethroid application in early January. The 1 day PHI interval should help with harvesting.

    Need to be completed by January 15th. 

    Contribution by Steve Farr​

    12/15/15 Counts are low but high for this time of year, we see this in most areas with this area having 38% flush currently and last year at the same time with the same trees, 10%.

    This is approximately 1-2 weeks post an Organophosphate regional application of Imidan by air or Malathion by ground, pending the block and location.

    Contribution by Steve Farr


    11/24/15 Count are low but higher than usual for this time of year. This is approximately 2-3 weeks post the Baythroid regional application done in early November. Possibly some of the pressure is from the weather the past several weeks, in that until this current cold spell, the month of November was on record to have the highest temperatures ever. This also shows from the flushing amounts, in that this area averaged 52% feathering flush and last year the same trees in mid-November averaged 15% feathering flush. As has been discussed next week will start an Organophosphate regional dormant application. Jerry Wise will be in this area towards next weekend around December 6, pending weather. He will be applying Imidan at 1lb/acre in 5gl of mix. Costs will be approximately $17.25 per acre.

    Imidan has a 3 day REI and a 7 day PHI.

    11/11/15 Counts are low, most of this area was sprayed just before this inspection, by air or ground with Baythroid. The next discussed regional application, is an Organophosphate material in early December.

    Contribution by Steve Farr

    11/9/15 Counts are rising. As has been discussed, a Baythroid regional application is going now. Working towards finishing by next weekend, Nov 14. Jerry Wise will be in this area this weekend, pending weather. Cost with material is less than $11.00 per acre. If interested reply to me or call Jerry 334-898-7772

    Contribution by Steve Farr

    9/23/15  Counts are very high. We are seeing this in other locations as well. Possibly the abundant rainfall and the fairly large amount of flushing is contributing to the pressure. This is approximately 3 weeks post Imidan by ground or Dimethoate by air. Also, in general, like other areas now and in the past, the aerial blocks in regional locations have lower counts than the ground sprayed blocks. All done at the same time, with the same rainfall, but better results were regional sprays are being done. There is also two different Organophosphate materials in this comparison, mentioned above.

    For October, we are looking at rust mite problems, thus will be using Envidor on fresh fruit blocks, but will be adding Lorsban or Chlorpyrifos for psyllids, has a 21 or 28 day PHI, depending on which material used.

    If enough participation, Jerry Wise can be back in this area to go by air.   If interested, reply to me.

    November, should be a Baythroid application, and Jerry will be in this area for this application.

    Contribution by Steve Farr

    8/28/15 Counts are low per block, but heavier than last year at the same time. Most growers are finishing the second oil sprays, we used Agri-flex with it.

    Jerry Wise will be going in this area sometime by the first of next week, depending on weather, and if interested reply to all or call Jerry at 334-898-7772

    Contribution by Steve Farr

    8/10/15 Counts are low for this area, not the case in others. Most of this area has had a second summer oil spray by ground with Agri-flex, and was done by air with the last regional application of Dimethoate in early July. Discussions for the next regional application is an Organophosphate material to go out late August or early September.

    Contribution by Steve Farr

    7/6/15 Counts are low, this is 3-4 weeks post the regional application of Baythroid. The next discussed regional application is Dimethoate starting this week. Jerry Wise will have at least two planes available. Costs for materials and application will be approximately $12.15 per acre. If interested reply to me or call Jerry 334-898-7772

    Contribution by Steve Farr

    6/4/15 Counts are on the rise , especially the nymphs. This is approximately 3- 4 weeks post the Malathion and Abermectin, applied by air and ground, pending the block. As usual, generally if you look at the report, the blocks with the highest counts, are the ones sprayed by ground, not air, with the same materials, but the blocks sprayed by ground are adjacent to blocks not participating with the chma aerial sprays.

    Growers are going with summer oil now, and most are either using AgriFlex, Movento, or Micromite. We are using Movento, but where possible, will be applying Baythroid for the adult psyllids.  Jerry Wise should be in this area in the next two days, pending weather.  Approximately $11.50 per acre, materials and application.

    If interested reply to me or call jerry The next regional application is early July with Dimethoate or another Organophosphate material. This application is also approximately $11.50 per acre, including the Dimethoate.

    Contribution by Steve Farr

    5/28/15   Counts are down.  This is approximately 1 month post the regional application of Malathion. This area also had a summer oil spray done in the last 4 weeks with Abermectin. This area will be going next week by air with Baythroid, approximate cost of $11.00 per acre.   If interested reply to all or call Jerry Wise334-898-7772

    Contribution by Steve Farr

    5/19/15 Counts are down, this is approximately 1-2 weeks post a Malathion spray done by air and ground, pending the block. The next regional application being discussed is an Organophosphate application in July. Most growers will be applying the first summer oil application from now through June. Should leave out an Organophosphate material and catch in July. This is usually Dimethoate, which has been one of the better and more economical applications. Also, the 14 day Post Harvest Interval, should not be a problem by July.

    Contribution by Steve Farr

    5/6/15  Counts are climbing.  This is approximately 4-5 weeks post the Danitol regional application. Some of this area has been sprayed by ground with Malathion and Abermectin, oil, nutritionals.  Most of the hot spots will be sprayed tomorrow by air with Malathion.

    The next regional application being discussed is an O.P. material going out in early July.

    Contribution by Steve Farr

    4/26/15   Counts are down. This is approximately 3 weeks post a regional application of Danitol, done by air or ground.

    The next regional sprays being discussed is an Organophosphate material in July. Most growers are going next (late April early May) with a post bloom spray and an Organophosphate material. Then in June with the summer oil sprays and a systemic material such as Movento or Agri-flex.

    Some discussions of doing another regional application by air in May with an Organophosphate material, which we all agree would be better for efficacy of the psyllids, but with 5 day minimum PHI and the Valencia harvesting, might be difficult.  Also, most growers are planning on a post-bloom spray during this time and will add the Organophosphate material to the mix. But if enough participation, we will go by air for psyllids, and by ground for the other targets. This area will be getting some aerial application with Malathion by the end of next week.  If interested reply to all or call Jerry 334-898-7772

    4/10/15 The graft shows the results of the Danitol, applied in the last 10 days either by ground or air, most of this area is aerial applied with participating neighbors. There is a lot of nymphs and the Pyrethroids are not that effective against the nymphs. The counts are lower than last year for the same time period, the only difference was last year no applications during march, this year Sivanto was available and used during the bloom. Danitol was used both years at the same time, rate and method of application in early April.

    The next regional sprays being discussed is an Organophosphate material in July. Most growers are going next (late April early May) with a post bloom spray and an Organophosphate material. Then in June with the summer oil sprays and a systemic material such as Movento or Agri-flex.

    4/9/15 Most of this area has had a Danitol application by ground or aerial with participating neighboring growers.

    The next planed regional application being discussed might be in July with an Organophosphate material. In the meantime, growers are discussing going with an Organophosphate next with their post bloom sprays, and then a systemic material, such as Movento with the first summer oil spray in June.

    Contribution by Steve Farr

    3/19/15 Counts are starting to climb. Approximately 2-3 weeks post Sivanto. As been discussed the next regional application will be as soon as the bloom and bees are gone. Looking like Monday March 30th, might be the start up time. Danitol, or another pyrethroid is the material planned. As usual, Jerry Wise will have 3 planes going in this area at this time.

    Contribution by Steve Farr

    3/4/15 Low counts of adults. Most of this area is going on 3-4 weeks post the regional Baythroid applications, done by air or ground. If you open the report and go to the tabs on the bottom and open the yearly comparison tab at the far right, you will see how the inspections compare the last 4 years (this year in black). From this we see the counts are about normal for this time of year, behind the 3 dormant sprays since December. Also the % flush is ahead of the previous 3 years (the effects of the increase in HLB trees). Most importantly, you can see what the pressures have done the last 3 years in the upcoming months of March and April. Thus the planning of a large participation with the next regional application with Danitol or another Pyrethroid ASAP after bloom. Danitol costs more, but most growers agree, it has had better efficacy, and with the timing of this being one of the highest pressures of the year, might make since to use one of the best materials. The 1 day PHI will help with Valencia harvesting. The key, as usual, is to get as many acres sprayed together in the shortest amount of time. Hopefully the bee keepers will cooperate and be gone ASAP after petal fall. Many growers are going now with Exirel, Movento, or Sivanto (if they got any). This should help keep the populations low going into April.

    Contribution by Steve Farr

    2/13/15 - 0  counts and high flush. This area just had a Baythroid application applied by air or ground.

    Discussion are to use Movento, Closure, Exirel, or Sivanto during bloom.
    Next regional application will be at petal fall (whenever that might be) and will be using Danitol.

    April is usually some of the highest counts of the year, and if you look at the yearly comparison spread sheet you will see this peak in April we have had the last 4 years of scouting. This is the case in the 10 other areas we scout. Thus will be working towards a large contingency of growers with participation at one of the highest pressure times of the year. Hopefully the bee keepers will cooperate and will have to work around Valencia harvesting, but the 1 Day PHI will help.

    The researchers tell us the longer it takes to get this application done, the more eggs and nymphs are getting established and it is much harder to get good efficacy when these numbers of nymphs and eggs are increasing with all the spring flush, as well as having to work around the bloom. Hopefully, with some of the new products available to use during bloom, growers can slow down the populations till the bees and bloom are gone. But regardless of what is done in bloom, they say April is the peak for movement and increases in populations throughout the state and their large scouting data shows that is the case the last 4 years.

    Contribution by Steve Farr

    1/29/15  Counts are 0, this is about 3-4  weeks post the Danitol sprays. We have been discussing about going with an Organophosphate material in February. Plan is to now go with another Pyrethroid, Baythroid, talking with Lake Alfred, not as much a problem with back to back chemistries when applying to the same generation of psyllids.
    With the low counts and very few nymphs or eggs, this should be the case we are currently in. Also the Baythroid has a 0 day PHI, and a 12 hour REI, which will help with the harvesting situations.

    Pending weather, this application should be done in less than two weeks. This is important to get this done before the main bloom and the bee pressures. The bee keepers we have contacted have agreed to wait to move any hives in, until this application is finished.

    Jerry Wise will be going with 3 planes starting Monday February 2. The cost for 3.2 ozs/acre of Baythroid, Adjuvants, and application will be less than $10.00 per acre.

    As always if interested, reply to me or call Jerry at 334-898-7772

    Contribution by Steve Farr

    1/7/15 Counts are low, but starting to climb. Also flush is ahead of schedule, when comparing this year to last year.

    The January dormant pyrethroid is going out now in full swing. Most growers are going by ground and adding nutritionals and coppers where needed. Jerry Wise is available if anyone needs applications by air.

    The February application looks like an Organophosphate material, pending harvesting.

    Contribution by Steve Farr

    12/8/14 Counts are rising approximately 4-5 weeks post the Baythroid application. Currently trying to spray an organophosphate material by ground or air. Costs per acre by air with Malathion, is approximately $14.00 per acre, materials and application. Weather and harvesting has made this application difficult. When the weather does change, Jerry Wise has 3 planes going in this area. If interested reply to me or call Jerry at 334-898-7772

    Contribution by Steve Farr

    12/01/14 Counts are down, approximately 4 weeks post the Baythroid aerial regional application.

    This area for December has been discussed to go with either a pyrethroid or Organophosphate. Jerry Wise will be applying by air an Organophosphate material this week for BHG. Will have to work around the 7 day PHI for Malathion. Where harvesting is not a problem, some Dimethoate will be used. If interested reply to all or call Jerry 334-898-7772

    Contribution by Steve Farr

    11/20/14 Counts are finally down, as well as the flush, and also the temperatures. Some growers are going in December with an Organophosphate material, working around the harvesting. The next large regional application will be after the first of the year with Danitol or another pyrethroid material.

    Contribution by Steve Farr

    11/4/14 Counts are slowly rising in this area. Most of the scouting was done before the Baythroid application, which is going on now. Two planes have been working with the weather in this area since Sunday morning. Should finish this area by ground and air, this week.

    Discussions going forward, is that the Danitol dormant spray usually goes on in early January. Growers are concerned with the increase amount of pressure we all are seeing the last several months, that there will be another application before January. Not sure what material, O.P. would be the norm, but the PHI will make a regional aerial application difficult to coordinate with harvesting at this time (late November).

    Will see how the counts look in two weeks.

    Contribution by Steve Farr

    10/30/14 Counts are up, approximately 2-4 weeks post a ground application of Imidan, Envidor and nutritional. We are seeing this in most other areas. The heavy flush for October has been beneficial but also a breeding ground for psyllids.

    As has been discussed, a regional application of Baythroid will start this weekend pending weather. Costs will be approximately $15.00/acre, applied at 10gl/acre. Jerry will have 3 planes available.

    If not already engaged, reply to me or call Jerry Wise, the pilot at 334-898-7772

    Contribution by Steve Farr

    10/20/14 Counts are low, generally lower than most other areas we scout. This is South of Frostproof area going to the county line.

    Discussions have been to go with a regional application of Baythroid, starting next week. Jerry Wise will be flying in this area by the end of next week, pending weather. If interested reply to all or call Jerry 334-898-7772

    Contribution by Steve Farr

    10/14/14 Counts are high. Been this way the last several inspections. See this in most other areas as well. Notice the flush %, 2 to 3 times more than the previous October flushes. We all like the flushes, unfortunately, so do the psyllids.

    Next regional application being discussed is a Pyrethroid to start the last week on October or early November.

    Baythroid a new Bayer product looks like the material to use by air.

    Jerry Wise will be flying this area and can be reached by replying to all or call him 334-898-7772

    9/23/14 Counts are down, this is approximately 2 weeks post the Chlorpyrifos aerial application. Discussion going forward is a regional application in November. Materials have not been worked out yet, most likely either an Organophosphate material or a Pyrethoid which was used last year in November.

    9/4/14 Counts are low. Not the case in other areas. Starting a regional application this week with an Organophosphate material. Jeff Summersil will be in this area next week with an aerial application using Chlorpyrifos, a generic Lorsban. 3pts/ acre going out at 5 gal/acre. This has a 5 day REI and 21 day PHI. Costs approx. $16.00 per acre. If interested, reply to me or call Jeff 561-722-4502

Cost is approximately $15.00 per acre. If interested, reply to me or call Jerry at 334-898-7772

    Contribution by Steve Farr

    8/13/14 Counts are still low. This is not the case in several other areas we scout. This is approximately 4 weeks after the regional application of Dimethoate, and most of this area has been or will be sprayed in the next two weeks with Agri-flex, oil, nutritionals, and copper where needed.

    The next planned regional application being discussed is for early September with Dimethoate again. This should be before any harvesting thus help with the 14 day PHI.

    Contribution by Steve Farr

    7/31/14   Counts are starting to rise, about 4 weeks post the regional aerial Dimethoate spray. As usual, this is still one of the lowest counts for an area we scout in. Some of the other areas, counts have gotten higher than we seen since we started scouting 3 years ago. We are in the process of a ground application with oil, agri-flex, and nutritionals and copper where needed.

    The next regional application being discussed is an Organophosphate spray in late August or early September. As in the past, Jerry Wise will be doing this area with Dimethoate, by air,  before any harvesting problems.

    Contribution by Steve Farr

    7/15/14   Counts are low, 10 days after the Dimethoate regional application, mostly done by air. We are not seeing as good of results in other areas, like in the past, this area has some of the better participation, most of the growers in this area participated with the aerial application.
    Going forward, growers are planning an oil spray in August, with nutritionals, copper where needed, and a miticide, also some will use Actara, or another imidacloprid. Also some are looking at Apta the new material.

    The next regional application will be another Dimethoate in late August or early September. Again, this can be done for less than $12.00/acre

    Contribution by Steve Farr

    6/23/14 Discussion going forward, is for a regional O.P. application to be done early July. Like mentioned before, Dimethoate at approximately $ 12.00/acre has been one of the best efficacy sprays we have seen in the last 5 years. It does have a 10 day REI. Jeff Summersill will be in this area and you can reply to me or call him 561-722-4502

    Contribution by Steve Farr

    6/16/14 Counts are down, following the Mustang or Malathion applied by air in the last two weeks. We are finishing our first summer oil with Movento and Imidacloprid.

    Discussions are for a Dimethoate application in early July by air. This is one of the more reasonable sprays at less than 11.00 per acre, and one of the better efficacy ones done by air, pending participation. The Dimethoate does have a 10 day REI. Thus some growers use other O.P. materials and can be arranged with the pilot.

    Contribution by Steve Farr

    6/4/14 Counts are up, a couple of hot spots are most of the populations. Have started the first summer oil sprays and have completed an aerial application in this area since this scouting was done.

    Plans are for early July for the next regional application with an O.P. material. There will be two planes available to apply Dimethoate at this time. Costs is less than $12.00 per acre.

    Contribution by Steve Farr

    5/19/14   Fairly low populations, this is post the Malathion, Abermectin, oil, nutritional, and copper.

    Discussions are going towards an aerial application of Mustang at the end of May. Jerry Wise will have two planes going in this area by the end of next week.  This should clean up adults going into the summer oil sprays.

    The next regional application being discussed after the Mustang is Dimethoate in July.  If interested, please let me know

    Contribution by Steve Farr

    5/13/14 Counts are low, but still have some hot spots. We are finishing the post bloom spray with Malathion, Abermectin, oil, nutritionals and copper. Have done some perimeter Danitol sprays also, around the hot spot areas.

    Discussions going on are to look at a Mustang regional application to knock down the adult pressure before the summer oil sprays start in June. Will have aerial applicators going around the last week of May. This will cost less than 12.00 per acre, materials and application. Harvesting should be completed.

    The next application behind this one will be the Dimethoate in July. If interested in the mustang by air, let me know.

    Contribution by Steve Farr

    5/1/14 Counts are starting to rise, we are seeing this in all locations. This is approximately 1 month post the Danitol regional application.

    Most of the pressure was around the peripheral borders of this area. We are in the process of spraying the entire area with Malathion, nutritionals, copper, Abermectin, and oil. This will take some time and will be jumping around the harvesting and the 7 day PHI, with this mix.

    Will be doing a perimeter spray to slow down the increase till the ground rigs can get there.

    Contribution by Steve Farr

    4/16/14   Counts are down, and basically this area has the least amount of pressure compared to anywhere else we scout in the last two weeks. This area had a very good participation with the Danitol applied 10 days ago by air in most of this area.

    Discussion going forward is to use an Organophosphate material with the next spray, which most growers are looking at including with their other miticides and nutritionals, or the standard post bloom spray. Jerry Wise will be available for aerial application, but harvesting and the 7 day PHI will make it difficult to get done by mid May. Thus, if spraying post bloom sprays look at an Organophosphate material to be included with the ground rigs.

    June in the past has been done with ground rigs as well with the first summer oil sprays, but an aerial regional application might work if growers are interested. An imidacloprid has been used at this time.

    For sure, the July application of Dimethoate by air has been one of the more successful and low budget applications in the past and is being planned on for this July.

    Contribution by Steve Farr

    3/29/14  Adult psyllids are on the move.   Some of the highest counts we have seen is some time.  Seeing this in most other locations, the adults are moving. Usually higher counts in the same areas we have had in the past.  Also a perimeter hit.

    Will be using Danitol this week, either by ground or air. Putting together the maps now, and will send out the information in the next two days.  All the bees should be out by this coming week, and will have to work around harvesting. The 24 PHI should help.

    Total costs, materials and application approximately 23.00 per acre.

    If interested reply to me

    3/18/14   low counts of psyllids, but starting to increase in most areas, approximately 8 weeks post the regional application of Danitol.  Also, most of this area has had a Malathion application with nutritionals in last 4 weeks.

    If you look at the report and see the grafts, you will see that the peak populations of psyllids generally happens in the late march/April time frame, the last two years.   For March and the bloom, there is some new materials that should help if the counts start to rise before the bloom is over (whenever that might be).

    The next important regional application will be just after petal fall, with Danitol, which has a 1 day PHI, that should help with the Valencia harvest.  There will be several aerial applicators working in this area at that time. Some growers are thinking by the last week in March (10 days), we will be at petal fall.
    In other areas the counts are going up now, and will be starting a perimeter spray tonight with Closer. Working towards keeping the counts low till we get to the Danitol regional application in 10 days, approx.

    This being said, growers are looking at doing another regional application before the main bloom in the next two weeks. This should help reduce the spike mentioned above. The organophosphate materials are being used now, to rotate behind the Danitol, and most likely another Danitol at petal fall, whenever that is, last year this was not until mid-April.  Thus if growers are using ground rigs with nutritionals and want an extra preventive psyllids spray before the bloom, an organophosphate material is encouraged to be used. Unfortunately, all of these have a minimum 7 days PHI.

    2/6/14 0 counts, approximately 4 weeks post the regional application of Danitol.

    If you look at the report and see the grafts, you will see that the peak populations of psyllids generally happens in the late march/April time frame, the last two years. This is during, or shortly after bloom. This has been the case in most all of the state, where growers are spraying for them, if they are not spraying for them, they will see peaks throughout the year. This being said, growers are looking at doing another regional application before the main bloom in the next two weeks. This should help reduce the spike mentioned above.

    1/20/14 0 counts, approximately 2 weeks post the regional Danitol application. Some discussion about February spraying, growers going with a systemic material such as Movento, Portal, or Grandevo, with nutritionals. Might need to add an adulticide material, O.P. material such as Malathion, Dibrom or Imidan. These will need a 5 day post-harvest interval.

    If we start seeing adults from the scouting, might put together an aerial application to go with neighbors in February to put out the O.P. material, and spray by ground as well with the other materials.

    With the amount of flushing growers are seeing, this might be the best scenario.

    The important thing is, with the bloom period in March (or whenever the main bloom is??), to try and get as good of controls as possible before the bees get started. The highest counts of the year are usually during or just at the end of the peak bloom, at least where growers are trying to spray for them. We do have some new materials that might help during this time which are supposed to be effective against the psyllids and not on the bees.

    Contribution by Steve Farr

    1/12/14 Counts are on the rise, most of the blocks on this report are getting aerial applied with Danitol today or tomorrow. As has been discussed the regional dormant application was attempted to be completed by the 15th. The windy conditions have made the two week window a little tighter to accomplish than other past applications.

    Most growers are seeing the increase in flush and are reporting higher than normal psyllids counts for this time of year. They are looking at going with a systemic material, such as Movento, Portal, or Grandevo in February with nutritionals before the bees get moved in.

    The next regional application will be at petal fall, possibly late March or early April. Last year this was not till April 15th. The material discussed will be a pyrethroid of Danitol or Mustang, which will help with the 1 day Post Harvest Interval. This time of year is usually the peak time of year for psyllids populations, thus the need to work towards a successful regional application with everyone engaged with working together.

    Contribution by Steve Farr

    1/9/14 Counts are on the rise.

    As has been discussed, the dormant Danitol application started last December 30th and were trying to finish by this coming weekend. The weather has not cooperated and growers as well as the pilots are behind the intended timing.

    There are 3 planes going out of Avon Park with Jerry Wise and Ag Flying Services, but the wind has held them up several days in the past week and a half. If it does calm down, all of the growers in the Bereah area that have indicated they wanted in on the aerial application, should be done by the end of this weekend.

    If you have not already done so and would like to be included, contact Steve Farr or call Jerry at 334-898-7772.

    Contribution by Steve Farr

    1/3/14 0 adults but a few nymphs found.

    Plan has been to finish all of this area with Danitol by the end of next week. The weather has made this week very unproductive for spraying. Next week looks to be about the same.

    Jerry Wise has 3 planes in the area, and if weather will let him, he should finish by the end of next week. If you have not already made arrangements to have your blocks sprayed with Danitol, you can reply to all, or call Jerry at 334-898-7772.

    12/27/13 Counts are starting to go up. with all the flush, not surprising. Plan has been to start the Danitol next week and be finished by January 13. Jeff Summersill will be applying aerially in this area.

    BHG, Flood, Alico, David Morris, Danny Norris, are in.

    You can call Jeff at 561-722-4502

    Or reply to all and it will get done.

    Contribution by Steve Farr

    12/19/13 Counts are lower in this area than a lot of other areas we scout. We are seeing much more flush for this time of year than in the last two years since we started the scouting. What this possibly could cause is more new generations of psyllids, especially in groves that have not been participating with the programs and these will be moving into the neighboring blocks. We are already seeing this in other areas where there is not good participation, like there is in the Bereah Area.

    Thus growers are discussing to start the Dormant Danitol Regional applications on December 30th and to be finished by January 13th.

    Jerry Wise will have 3 planes going in Highlands, Polk and Hardee counties at this time.

    You can reply back to get included or call Jerry at 334-898-7772

    Contribution by Steve Farr

    12/11/13 Counts are staying low. This is approximately 4 weeks post the Mustang Regional application. We are seeing increases in many areas, but the general plan is to start the Danitol Regional application December 30th. As usual, there will be at least two different pilots in the area and some contract ULV applicators as well. Plan is two finish all of this area in two weeks, does not matter how it is done, just needs to be done with Danitol, or Mustang in the two week interval.

    11/26/13 0 counts, 2 weeks post Mustang Regional application.

    Contribution by Steve Farr

    11/5/13 1 psyllids found, in the entire area north of Frostproof, all the way to east of Lake Wales on Hwy 60. This particular block is in an area that has not had much regional participation and has had pressure in the past. This is approximately 6 weeks post the Dimethoate regional application.

    Most growers are discussing going with the next regional CHMA application in November, with Mustang. This application in the past , has been considered the first dormant application, and has been effective to keep populations down, going into the winter and setting up for the January Danitol application. Jeff Summersill will be aerial applying in this area, starting around November 11th.

    11/4/13 Scouts found very few counts this past week in the groves south of Frostproof. This is approximately 2 weeks since the perimeter sprays were applied with an Imidacloprid. As has been discussed, starting today, November 4th, the regional sprays will begin with Mustang. Jerry Wise with AgFlying Services will have 3 planes spraying in all of south Polk county and central to north Highlands county, as well as some of Hardee County.

    10/17/13 Counts are 0, again, this area has had the least amount of pressure out of all the areas we scout in 5 counties. This is approximately 4 weeks post the Dimethoate regional application. We are currently doing a perimeter spray with an Imidacloprid on all areas. Trying to keep populations down till November.

    Most growers are discussing going with the next regional CHMA application in November, with Mustang. This application, in the past, has been considered the first dormant application, and has been effective to keep populations down, going into the winter and setting up for the January Danitol application.

    10/2/13 Counts are down, 2 weeks post the regioanal application of an Organophoshpate material, most of this area had a dimethoate application done by air.

    Discussion going forward is to coordinate a Pyrethroid regional application in November. The 1 day PHI, should help with this application.

    Contribution by Steve Farr

    9/24/13 0 counts, but approximately half of the blocks were not scouted because of REI behind the Organophosphate regional application.

    Next regional application being discussed is in mid-November, this will be the first dormant spray and will be using Mustang. Thus, if any insecticide use before then, growers should not use a pyrethroid. This is even more important, in that, the January application will be Danitol, thus the need to not use a pyrethroid before November.

    Contribution by Steve Farr

    9/19/13 Latest report, 0 psyllids, although some of the blocks were not scouted because of REI's from the regional application of an O.P. will be back in this area to scout in 2-3 weeks. This application should be finished by the end of this week.

    Growers are discussing that the next regional application will be in November with a Pyrethoid material. Thus if any sprays are needed before then(rust mite, brown rot), other insecticides should be used besides Mustang, Danitol, or Gladiator.

    Contribution by Steve Farr

    9/9/13 Counts are starting to rise. This has been mostly the same in all other areas

    Growers are finishing their second oil sprays, and the discussion is to go with a regional application, starting September 9th, and using an Organophosphate material. There will be coordinated aerial sprays going out with mostly Dimethoate being done in this area. Total cost of less than $11.00 per acre (materials and application)

    If you have not already gotten engaged, you can do so by replying to all or call Ag Flying services at 334-898-7772

    8/26/13 5th inspection with 0 counts. This is the best area for low counts, which we scout, in 5 counties!!!!

    Discussion is to start September 9th with Dimethoate by air, or an Organophosphate material by ground. This area should be done towards the end of this week of the 9th by air.

    Contribution by Steve Farr

    8/23/13 Low psyllids found, 3 inspections in a row. This is approximately 4-5 weeks post the regional application of an Organophosphate. Also 75% of these blocks have been sprayed with oil, Agri-flex, and nutritionals in the last 2 weeks. Will finish the rest by labor day.

    Next regional application being discussed is to start September 9th. Using an O.P. material.

    Contribution by Steve Farr

    8/6/13 0 psyllids found for the second inspection in a row. This is approximately 3-4 weeks post the regional application of Dimethoate. Also if you look at last year's graft, the spike we saw in June and July last year did not happen this year. The materials and timing were about the same this year to last year, but this year there was much more participation in this area with the regional aerial applications!!!

    Growers are going with their second summer oil sprays now and using neonicotinoids with the oils (imidacloprid or Actara materials).

    The next regional application being discussed is to go with Dimethoate by air starting in mid-September

    7/12/13 Maintaining low counts of psyllids. This is approximately 3-4 weeks after Mustang or Imidacloprid. Growers are going with a fast know down of an Organophosphate material, generally Dimethoate or Imidan, being applied by air or ULV at night.

    Contribution by Steve Farr

    7/8/13 1 psyllids found after 4 weeks of an aerial application of Mustang. Plan is to start this week with Dimethoate by air.

    Contribution by Steve Farr

    6/28/13 0 psyllids for this area. This is 1-2 weeks post an aerial application of Mustang, or ground application of an Imidacloprid. All of this area is also getting a ground application of Movento, oil, nutritionals and copper (where needed). If you look at the graft, June had a spike in populations last year, but thus far this year we have not seen this. Some of this is because of the increased regional spraying effect, and a lot of this area has had good participation with aerial applications. I have included another area we scout that has not had as much cooperation with the regional sprays and you can see the difference. Again, both areas are being sprayed with the same materials and timing, but very different in participation amongst the neighboring growers.

    The next regional spray is being lined up to go with Dimethoate in July. Looking at doing the entire area starting around July 8 and finish in two weeks or July 21. If you have not participated with the aerial application before you can reply back to me or call Jerry Wise at 334-898-7772. Also, there are several contract ULV machines available to do areas the plane cannot get into. Or if you are spraying anyways with ground rigs, the program would call for an O.P. material if Dimethoate is not used(Imidan, Lorsban,Dibrom, Malathion)

    Contribution by Steve Farr

    6/25/13 North Frostproof counts are very low. 1 adult psyllids found. This is 1-2 weeks post an aerial application of Mustang, or ground application of an Imidacloprid.

    6/21/13 Bereah counts are down. Most of this area just had an application of Mustang done by air. Also Appling Movento with nutritionals and copper by ground now. If you look at the graft, last year there was a peak in June, we have not seen that thus far this year. Also, in general, the counts for this year in this area are LOWER than last year. This is NOT with more sprays, but this area has had more participation than most other areas we work in. Generally, this area has had aerial applications of Danitol, Imidan, Mustang and Dimethoate since last August only. All the ground applications have been with miticides, nutritionals and copper where needed and leaving the psyllids materials for the plane. We have higher counts in other areas where we use the same materials, by ground with the above insecticides, and have better coverage with the ground rigs than what a plane can do at 140mph and 5 gal/acre. BUT we take, like most growers 4+ weeks to spray (depending on weather) and we do not spray in conjunction with our neighbors. Thus, why our counts are lower than last year.

    The next regional spray is being lined up to go with Dimethoate in July. Looking at doing the entire area starting around July 8 and finish in two weeks or July 21. If you have not participated with the aerial application before you can reply back to me or call Jerry Wise at 334-898-7772.

    6/13/13 Counts are low. A lot better than some of the other areas we scout that has less participation with the coordinated sprays. Currently there is an aerial application of Mustang go on. Discussion is to go with Dimethoate in July. Thus growers are not using any O.P. materials in their June summer oil sprays.

    This is approximately 4 weeks. post an Imidan application, mostly done by air. If you look at the graft and last year in June we had a spike before the July regional dimethoate got on. We are going to go by air starting this week again with Mustang, if anyone in this area would like to be included let us or Jerry Wise know. We have just seen the better results were the whole area gets hammered at one time vs. the same materials getting put out over a longer time, thus we will be basically spraying the same blocks twice in the month of June, but the Mustang will go out by air with our neighbors (the ones who want in) and our ground rigs will focus on rust mites, canker, and coverage, (as well as some psyllids control with the oil and Movento).

    Our net additional cost is only 5.75/acre for the plane application, and we feel for the better psyllids control this is a good investment. Thus if you would like, just use whatever miticides,oil, canker controls and nutritionals by ground, and the regional application of Mustang by air, Plus you kind of get a double hit, in that the oil and agrimek by ground will do some good on the damn nates and the air/mustang is another attack, or hit on the psyllids at two different times in the same month

    Growers are looking at a Dimethoate aerial application in early July, thus need to leave out an O.P. material in this June summer oil spray.

Plus you kind of get a double hit, in that the oil and agrimek by ground will do some good on the damn nates and the air/mustang is another attack, or hit on the psyllids at two different times in the same month.

    Growers are looking at a Dimethoate aerial application in early July, thus need to leave out an Organophosphate material in this June summer oil spray.

    Contribution by Steve Farr

    6/6/13 Counts are down, approximately 3 weeks post an Imidan application, mostly done by air. If you look at the graft and last year in June we had a spike before the July regional dimethoate got on. We are going to go by air next week again with Mustang, if anyone in this area would like to be included let us or Jerry Wise know. Discussion going forward is most growers starting a summer oil spray with nutritionals and copper. Insecticides being used are either a nionic or a pyrethroid. Growers are looking at a Dimethoate aerial application in early July, thus need to leave out an O.P. material in this June summer oil spray.

    Contribution by Steve Farr

    5/21/13 Counts are low, in the process of finishing an oil, agrimek, nutritionals and copper (where needed). Also have out Imidan by air, ULV, or with the materials above, depending on location. The next regional application being discussed is for late June or early July to go with Dimethoate or another Organophosphate. Thus, will need to not use an Organophosphate material in June summer oil spray.

    Contribution by Steve Farr

    5/13/13 Oak island area, no adult psyllids found. This is approximately 3-4 weeks after the regional application of Danitol. We are in the process of doing an aerial application of Imidan, and using agrimek, oil, nutritionals and copper(where needed) by ground.

    The next regional application is being discussed to look at Dimethoate in early July. Thus growers need to leave out any O.P. materials in their June summer oil sprays. Per Lake Alfred, June is a good time to put an Imidacloprid with their oil, or Agriflex.

    Contribution by Steve Farr

    5/7/13 Psyllids counts are starting to rise. This is post the Danitol regional application done approximately 3 weeks ago . This area currently has one of the highest counts of psyllids that we scout in. If you take the time to look at the state inspections for cycle 30 you can assume why, the Hesperides area has some of the highest counts in the state!!!

    Growers are going with post bloom sprays and using a miticide, oil, nutritionals, and copper where needed for canker controls. We are doing some perimeter sprays at night, but will coordinate an Imidan application in the next two weeks by air. The reason for spraying this area by air during the same month as we are spraying the same blocks by ground with the materials mentioned above, is that we have SEEN the better controls of applying the whole block in one day verses taking a month to spray the block by ground, and even better controls if the immediate neighbors get done at the same time.

    If anyone in this area would like to be included, let us know. Cost will be approximately 19.00 per acre, 1# Imidan, plus buffer/adjuvant and 10 gl/acre aerial application

    Contribution by Steve Farr

    4/22/13 Psyllids populations have dropped. We are approximately 75% completed with the Pyrethroid regional spray. Discussion going forward is to use an O.P. material in May with post bloom sprays. The next coordinated aerial spray is being discussed to look at July between the summer oil sprays and us an Organophosphate material such as Dimethoate.

    Contribution by Steve Farr

    4/10/13 As you can tell, this area has the highest amounts of psyllids we have found since we started scouting. This region has been discussing going with a Pyrethoid, Mustang or Danitol as soon as the bloom is done. There will be aerial applications starting next week in this area.

    Contribution by Steve Farr

    3/29/13 Like most places, psyllids counts are starting to go up. This report shows that last year the psyllids peaked in mid-April. This is generally true across the state, thus the importance to look at a regional spray soon. The discussion has been to start as soon as the bees and bloom is gone (whenever that will be) There are aerial applications lining up for this area, as usual. Materials being looked at is an O.P. material, if Post Harvest can be worked out. Or Mustang, but many growers have used pyrethroids the last two sprays (Danitol and Mustang), thus need to change chemistry.

    Contribution by Steve Farr

    3/22/13 Psyllids counts are starting to rise. Discussion has been to start a regional application as soon as the bloom is finished, which could be another two weeks minimum. Growers are discussing going with Mustang or Imidan. Depending on harvesting and what was used last. An aerial application will be initiated as soon as the bloom is finished with one of these two different chemistries.

    Contribution by Steve Farr


    3/7/13 0 counts of psyllids. This is post 2-3 weeks since a perimeter spray of Delegate. Discussion going forward are to look at a regional petal fall spray (whenever the bloom is gone) with either an O.P. material, if harvesting can be worked out, or another Mustang spray.

    Contribution by Steve Farr

    2/28/13 1 psyllid found on this last inspection. This is approximately 7 weeks after the Danitol Regional application. We have also sprayed the young solid blocks with Portal and nutritionals the last 3 weeks, and on all the rest of the older blocks we finished a perimeter spray with Delegate at night. The discussion going forward, is to see how long before we all start to see an increase in counts. With the scattered flushing we all have had the last 2 months and some growers still not participating with the dormant sprays, these increases could be before the bloom and bees are gone. The last 3 springs, were we had more of a dormant winter and fewer flushes, we did not see the increase until after the bloom and bees were gone, which obviously made it nice for the petal fall regional applications we all have participated in the last three springs. This area is currently looking at the possibility of doing a regional night spray with aerial equipment. Again, pending on the psyllid pressure and how long the bloom stays around. If we can get to petal fall, growers are discussing either going with an O.P. material which could be a problem with harvesting, or an Imidacloprid.

    Contribution by Steve Farr

    2/7/13 0 counts of adults and nymphs found. This is approximately 3 weeks post the Danitol application. With all the sporadic flushing happening the last several weeks, this is probably going to make it a challenge to keep low levels of psyllids through the petal fall(whenever that is) without spraying during the bloom.

    We have started spraying with nutritionals, oil and Portal on the solid young blocks that we assume will have the most potential pressure, and with most if not 100% of these 5 year old solid set blocks closing in on full bloom

    Contribution by Steve Farr

    1/28/13 0 counts. This is approximately 2 weeks post the Danitol application. 44% flush, this is probably going to make it a challenge to keep low levels of psyllids through when the bloom ends (whenever that is) without spraying during the bloom.

    We are starting next week with nutritionals, oil and Portal on the solid young blocks that we assume will have the most potential pressure, with most if not 100% of these 5 year old solid set blocks closing in on full bloom, in January.

    Contribution by Steve Farr

    1/22/13 0 counts of psyllids, this is approximately 5 days post the regional application of Danitol depending on which section. The Ft. Meade area is still getting sprayed and the pilot only has approximately 6 hours flying time to finish the blocks on the north end of this region. Notice the flush compared to last year at the same time of year. Going forward the discussion is to coordinate a petal fall spray (early March?) with an Organophosphate material. This will be interesting with the different stages of flush and the timing with Bee keepers and harvesting. The Organophosphate materials generally have a 7 day PHI. Our plan is to start a systemic material spray with nutritionals in the next two weeks to try and get ahead of the majority of flush, and protect the flush through the bloom period and get to the petal fall spray in March. This obviously, can/will change.

    1/15/13 Counts are down, this is approximately 10 days post the regional application of Danitol. Notice the flush compared to last year at the same time of year.

    1/12/13 Psyllids counts are low and the blocks that did have psyllids are in the process of being sprayed. Finishing the Danitol dormant spray by the Wednesday. Notice the amount of flush compared to same time last year(31% vs 3%). Our plan is to turn around with another spray, before bloom(if possible) and use a systemic material to control nymphs. Next regional spray discussion is to go with a Pyrethroid or Organophosphate shortly after petal fall (might be sooner than normal-whatever normal is anymore)

    Contribution by Steve Farr

    1/9/13  South Frostproof area report shows low levels of counts, were they did find psyllids is in blocks that have not been sprayed yet with this ongoing regional application of Danitol. The blocks that did have counts from the previous inspection that have been sprayed with Danitol are now all 0.  Plan is to finish this area by January 15th.  Also if you compare this inspection to the same time last year's inspection you will see the pressure a little higher but also the % flushing was 1.4% compared to 33.6% flushing going on now.  This has been discussed and based on Lake Alfred, the timing of this "dormant" application needs to be done asap.

    Contribution by Steve Farr


    1/7/13 There is a little reduction in psyllids pressure since the last inspection 3 weeks ago. Some of the areas that had psyllids 3 weeks ago have been sprayed with the danitol, thus the reduction. The goal was to be finished with this dormant application before January 15th. The weather has held up some of the applications, thus not sure this goal will be met. If you compare this inspection to last years inspection at the same time, you will see a little more psyllids counts, but the %flush is 32% now compared to 3% last year. Confirming the need to get the danitol spray on asap.

    Contribution by Steve Farr

    12/21/12 Unfortunately, the psyllids pressure is on the rise.Also increase in flush, which usually means the more flush the more psyllids. As has been discussed, with all the defoliation last month and with the warm December(so far), this is setting up to create the situation we are seeing. The plan is to start the Danitol regional spray Wednesday Jan 2. Some growers are going ahead and starting next week, because of harvesting. The Danitol does have a 24 hour post-harvest. There will be two planes and contract ULV machines available to complete this regional spray, and the goal is to finish by January 15th.

    12/19/12 Unfortunately, the psyllids pressure is on the rise. This is the first location that has shown this amount of increase. Also 20% flush, which usually means the more flush the more psyllids.

    12/14/12 0 counts with very low flush, this is approximately 4 weeks after the regional application of Mustang. Discussions are for the next regional application of Danitol to be done in January. Last year on this report there was an increase in counts in December before the Danitol sprays in January. With all the defoliation the last month, and if/when we see 80 degrees, we could see more flush and psyllids.

    Contribution by Steve Farr

    12/10/12  Low counts with very low flush.  This is approximately 3 weeks post the regional application of Mustang.  Discussions are for the next regional application of Danitol to be done in January.  Last year there was an increase in counts in December before the Danitol sprays in January.   With all the defoliation the last month, and if we continue to see 80 degrees, we could see more flush and psyllid pressure before we get to January.

    11/26/12 Very low counts, this is approximately 2 weeks post the regional application of Mustang. Discussions are for the next regional application of Danitol to be done in January.

    Contribution by Steve Farr

    11/16/12 Psyllids counts are predominately low, but do have a couple of hot spots to address. This area would of have already been done with the regional application of Mustang, but the weather has slowed the application. Weather pending, 3 planes will be in the Bereah area this weekend and should complete all the growers that have replied. This is approximately 2500 acres of blocks for the planes and several more went with ground rigs and/or ULV at night.

    Steve Farr

    10/27/12 Psyllid pressure is starting to rise. This is approximately 6-7 weeks since the regional Dimethoate spray done in early September. The discussion now is to go with a dormant spray sometime in early November. Most growers are talking about using Mustang. There will be 3 planes available to go during this time. Approximate cost should be less than $11.00 per acre. If interested reply to all and we can work it out, some of the growers on this e-mail list have participated in the past and will be contacted next week to get coordinated. Also, Hunter Prescott is putting together a regional application for groves east of Lake Wales and along Hwy 60 and you can contact him direct at Prescott, Hunter PrescottH@helenachemical.com also David Terrell will be going in this area with ULV machines at night and can be contacted at 863-781-0536.

    10/26/12 Psyllids counts down, but starting to rise. This is approximately 5-6 weeks since the regional dimethoate application. Discussion going forward is to do a dormant pyrethroid regional application in early November. There will be 3 planes available to do this first dormant spray, if needed. Approximate cost for application and materials is $11.00 per acre.

    Contribution by Steve Farr

    10/22/12 Psyllids counts are down, but starting to rise. This is approximately 5-6 weeks since the regional dimethoate application. Discussion going forward is to do a dormant pyrethroid regional application in early November.

    One of the blocks that shows the highest amount of psyllids(2), is a one year old solid set block that is getting soil drenchs with the neonicotinoids (Admire Pro) every 6 weeks. This is not the first time we have seen adults on resets or young trees (all the young trees get a heavy rate of Imidacloprid every 6 weeks), thus the need to obviously coordinate the regional sprays and not depend on the soil drenches for resets as the ONLY method of psyllids control.

    Contribution by Steve Farr

    10/16/12 Psyllids counts down. This is approximately 4-5 weeks after the regional dimethoate application. Discussion going forward is to do a dormant pyrethroid regional application in early November

    10/9/12 There was 1 psyllid found on 490 trees scattered across south Frostproof area. The psyllid counts in the Bereah area are down as well. This is approximately 3 weeks after the regional application of an O.P. material.

    Discussions going forward are to look at a Pyrethroid dormant application in early November. Pending flush, this should be the last psyllid spray of the year.

    Contribution by Steve Farr

    9/17/12 The latest scouting report. This one is not complete, the regional aerial application got in the way. But from this where they did scout before the application, where the scouts found psyllids was mostly against the edge of the block and next to growers that have not participated in the past.

    But this past week, the planes did a fairly large region, with some new grower participation and will see how the efficacy worked in 10 days after this application. Will send out the information.

    Discussions going forward have been to look at a REGIONAL application in early November with a pyrethroid material. This should be a good time in that most other sprays should be finished (pending spider and rust mites and maybe brown rot), also the short REI and PHI with harvesting going (hopefully).

    9/11/12 The psyllids are starting to increase in populations. This is approximately 4 weeks post an Agri-flex spray. Most of the pressure is on blocks adjacent to growers that have not been participating with the regional applications. We are seeing significant differences in the psyllids populations based on areas were growers have cooperated with the regional approach to spraying for the psyllids. This area north of Frostproof had a big regional spray done in July with an O.P. and based on this report you can see how low the populations were through August. We did not see this in other areas that did not have the same participation with the July regional applications.

    This is not rocket science, the more area that can be sprayed with the same A.I., at the same time, the more efficacy one will get.

    As discussed before, this area is going with an O.P. application currently, and was trying to finish before the middle of the month. There will be two planes spraying this area by the end of this week (pending weather).

    Contribution by Steve Farr

    9/10/12 This lattest report shows a small increase in populations of psyllids. Most of the blocks are still riding the Agriflex or Actara applied approximately 3-4 weeks ago. This area is still one of the better areas for low populations that we scout.

    As discussed earlier, there is a regional application currently going with an O.P. material. David Terrell will be available to contract applications and there will be some aerial applications as well going on this week.

    Contribution by Steve Farr

    8/27/12 Psyllids are starting to come back, still in low levels. This is approximately 3-4 weeks post oil and agri-flex spray. Discussions, regional spray going early September with an Organophosphate.

    Contribution by Steve Farr

    8/8/12 Psyllids counts are down for Frostproof area, currently. This is approximately 4 weeks behind the regional application of an O.P. material done in early July. Most growers are in their second summer oil sprays and are trying to get their rust mite populations in control. We are about 50% completed with our oil, abermectin, actara, and nutritional spray. Most growers are finding heavy mite populations.

    Psyllids counts are still down again for the Bereah area. This is aprox 4 weeks after the regional application of an O.P. material done early July. As mentioned from the last e-mail, there was a good participation with the last regional spray and shows the continued low pressure from the participation. We are finding heavier pressure of psyllids in other areas that do not have as much participation.

    Growers are discussing about going with another regional O.P. application in late August or early September. This would follow their second summer oil spray and would be before any harvesting gets started. Would probably be the last attempt of a regional application until the dormant sprays in November.

    Contribution by Steve Farr

    7/23/12 There is a reduction in the overall psyllid pressure in the Bereah area. This is aprox 10 days post the Dimethoate regional application. The Bereah area, has showed the biggest decrease in psyllid counts than any other area we scout in, over the last 2 weeks and since the regional application was started the last week of June. This is interesting in that all the other 10 areas in 5 counties were done with the same regional application attempts and with the same materials applied the same way.

    One big difference in this area is, in general, there is more participation with most ALL growers in this area. Either all the acreage was done by air, at the same time, or there was some ULV work being done at night at the same week with the same materials. Also a few growers were still applying their first summer oil and added an O.P. material with their oil, nutritional sprays.

    Regardless, we think this lower counts in this Bereah area than all the rest of the areas, basically is because of the grower participation with this regional application.

    This being said, the discussion now is that most growers are going with their second oil sprays with nutritionals and are trying to work on the building rust mite pressure. Some are including a neonicotinoid material for the psyllids and leaf minors.

    The next regional application is being discussed to go in late August or early September with another O.P. spray. Thus, growers are recommending to not us an O.P. material with their oil sprays now.

    Contribution by Steve Farr

    7/12/12 A coordinated spray is taking place this week in the Bereah / South Frostproof CHMA. The selected material for the application is an Organophosphate. The area wide application will continue through the end of the week.

    5/30/12 The counts from the previous inspection was at a total of 30 nymphs and 8 adults and are now down to 12 nymphs and 3 adult. This is approximately 3 to 4 weeks post an Abermectin, oil, and Imidicloprid, spray. These blocks also had a perimeter spray only, done last week with Imidan. Most growers are discussing of starting a summer oil spray soon going with nutritionals, coppers, oil, and a broad spectrum material such as Movento, Portal, or Agri-flex.

    Also most growers are wanting to shoot for the next regional spray to be late June or early July with an O.P. material, thus if possible, need to leave out any O.P. materials in the next spray.

    Contribution by Steve Farr

    5/16/12 Steve Farr has contributed the following information. The next regional spray will likely occur in late June to early July, using an organophosphate material. Once the exact date of the coordinated spray is known it will be posted to the latest new of this CHMA's website.

    4/2/12 Steve Farr mentioned surveys indicate that these are the highest psyllid counts we have found since we started scouting last year, in this area. This is also the highest we have found in any area in the last couple of months. Why? 1) most recent area done, and all of the state is on a huge increase and will see this continue in all areas until sprays are done,
    2) a lot of Murcotts in the Bereah area, and no doubt Murcotts attract psyllids right now in that if you look on the report at the feathering flush information, you will see a trend with the more feathering flush the more psyllids and murcotts are always behind other varieties, unless hedging has caused some new flush which we see as well on blocks that were hedged in the last few weeks and
    3) a lot of young solid blocks in Bereah and they as well attract psyllids, some are starting a second flush to compound the problem.

    As has been discussed, the plan is to start a.s.a.p. behind the bloom with an O.P. Some have already started, and are also applying nutritionals and coppers.

    The aerial applications will be starting this week.

    Have not heard from many to be included with this, but most are going with their ground rigs and wanting to apply nutritionals and coppers at the same time as the O.P.

    Harvesting will be somewhat of a problem in that the PHI for the O.P. materials is a minimum of 7 days.

    Our plan is to be finished with the area, either by plane or ground rigs, by the end of next week.

    If you want to be included with the aerial application, call Jerry direct at 334-898-7772

    4-26-12 Lattest psylid report. This reports was completed 3 to 4 weeks after the last spray application, using an Organophosphate. There is a consistency between increasing ACP pressure and increasing amounts of tree flush. There has been more ACP pressure observed on the perimeters and edges of groves as compared to the interior. The young blocks that were previously sprayed first generally are showing the most ACP pressure.

    Last week marked the beginning of the post – bloom sprays with Oil, Abermectin, Copper, Nutritionals, and Imidacloprid

    Steve Farr

    We are starting to find them around the perimeters of the blocks and also on the South East sides of the blocks. The plan that has been discussed it to go with an O.P. material after bloom. We are seeing similar finds in most of the other areas in the state. Some growers are doing a perimeter spray only at night to get to the petal fall period.

    Plan is to have an aerial application available after bloom. Will be difficult to schedule with different stages of bloom and harvesting and growers wanting to add a nutritional. Regardless, many growers are planning to start in the next two weeks and use ground rigs with an O.P. material and nutritionals.

    As always, the key is to spray as close as possible and with the same chemistry, which for this application is an O.P., such as Imidan, Dimthoate, or Malathion.

    Steve Farr (2/22/12) released the latest psyllid scouting report for our South part of Frostproof area. This is about 6 weeks after the regional application of Danitol. This is the second consecutive time the scouts did not find any psyllids in this area since we started the scouting program last August. Were we have checked in blocks that did not participate with the Dormant regional spray, we are finding low populations but can find some, and it is these adult psyllids that will be producing the nymphs that will become adults and will be foraging to adjacent groves in the next few weeks.

    The next regional spray is being discussed to start after bloom, probably in late March, with an O.P. material.

    I will be forwarding some research material that shows were we are headed with psyllids building a resistance to our current insecticides and if you look at the research you will see that the URGENCY in working together to prolong the inevitable from happening when it comes to psyllid resistance.

    We think most growers agree that the nutritional programs are making a difference in their bottom line today, but also most growers agree that psyllid management MUST be part of this strategy to stay profitable. Currently, the only strategy we have is to spray for them, and without a doubt, the best way to do this is with these regional efforts, using the SAME materials, at the SAME time.

    Bereah Report:

    Steve Farr on February 22, 2012 provided the following information. The psyllid scouting report for our Bereah/West Frostproof area. 0 psyllids found, this is about 6 weeks after the regional application of Danitol. If you look at the attachment you will see this is the first time the scouts did not find any psyllids in this area since we started the scouting program last August. Where we have checked in blocks that did not participate with the Dormant regional spray, we are finding low populations but can find some, and it is these adult psyllids that will be producing the nymphs that will become adults and will be foraging to adjacent groves in the next few weeks.

    Growers are looking at February to go with a miticide/insecticide material such as Movento or Portal.

    The next regional spray is being discussed to start after bloom, probably in late March, with an O.P. material.

    This being the plan, growers that plan to spray in February SHOULD NOT USE an O.P. material.

    South Frostproof Report:

    From Steve Farr on February 3, 2012. 0 psyllids found, this is about 2.5 weeks after the regional application of Danitol. Although in general the populations are down this time of year, we have seen large amount of psyllids in groves that are not being sprayed for various reasons and this is what we all will have to contend with during the spring flush.

    1/5/12 – As you know, the Danitol has been one of the more effective applications for the psyllids the last 3 years and needs to be done before the spring flush.

    The next coordinated psyllid spray will begin on Thursday, January 5, 2012 using a pyrethroid (i.e. Danitol or Mustang). If you are interested in participating in the application contact Chris Oswalt at 863-519-8677 ext. 108 or wcoswalt@ufl.edu.

    9/13/11 - The next planned regional spray is coming up in September and the general thought is to go with an O.P. sometime around the middle of the month. There will be two planes and 3 different ULV contractors with several machines available that will be working in these areas if you would like to participate. Also, as always, many will be spraying with their ground rigs and adding nutritionals as well. Again, the main thing is to spray as many acres as possible with the same chemistry (O.P.) at the same time. In this case from September 12th through the 26th. Most growers are looking at Dimethoate in this application in that the Post Harvest Interval of 15 days should not be a problem, yet, and this material has done an admirable job for everyone in the past. The $10 to $11 costs of materials and application per acre also helps.

    8/15/11 – Discussion going on about the next regional spray effort for Bereah / South Frostproof.
    Most growers are in the middle of their second oil spray and are using an imidicloprid, or Actara material, with the nutritionals, coppers, and miticides. Were we have not sprayed yet, and are 1 month out from the July regional spray with an O.P. material we are scouting these blocks and the psyllid counts are still low, other than some hot areas that are usually located next to a grower who is not concerned with the psyllid populations this time of year.

    We are starting to see significant differences in the psyllid populations based on how well the areas are getting treated as a whole region. This is encouraging for the investments the growers are spending towards psyllid management.

    This being said, the discussion for this area is to go with another O.P. spray sometime in the middle of September. The PHI of 5 to 15 days should not be a problem at this time. Many growers are looking at using Dimethoate with an ULV application at night or by air in the day.

    As always, it is about the timing and the materials being used, and not as important about how it is done. But if we can get enough big areas together we can use the planes. Were growers have done this in the past, they are seeing longer intervals between the sprays without getting hammered with new psyllids.

    This application can be done for approximately $10.00 per acre.

    Further down the road we are looking at maybe one more spray in October/November, with a pyrethoid. If rust mites are not a problem and we can get in after the fall scattered flushes, then we might want to do another regional spray with the ULV machines and/or planes. This would be considered a dormant spray and IFAS feel that this one and the January dormant sprays are the most effective psyllid sprays of the year.
