    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

    8/3/16 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

    6/27/16 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

    4/19/16 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 three 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 neonics. These are economical and have had some success, will also help with leaf minors.

    The next large regional application being discussed is an O.P. 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

    2/17/16 Counts are 0. As has been discussed, just finished with a Pyrethroid by ground. With nutritionals, and PFD concerns, made the aerial application too difficult.

    The March regional spray used last year, was mostly done by ground as well, with the bee problems and various materials being used. Many went with Sivanto which is bee friendly and reasonably costs. Other options as well.

    The first of April has been one of the key regional sprays done the last several years, and most growers worked to get their bee contractors out of the groves asap after petal fall, which we have seen a large influx with psyllid populations at this time of year. Will have to monitor when petal fall is this year, or which bloom period we consider is the main bloom to spray after petal fall. This bloom season has not been a typical or normal season thus far by any means.

    Contribution by Steve Farr

    1/12/16 Counts are lower but high for this time of year, if you look at the comparison tab on the bottom, it shows an easy graft to compare. This is approximately 4 weeks post the Imidan application done by air and ground, depending on the block.

    We are in the middle of a ground application of Danitol. Added other materials and with harvesting, aerial application would have been difficult. The goal was to finish the Danitol in this area by January 15.

    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

    12/30/15  Counts are high, we see this in all areas, 61% flush and obviously abnormal weather is having an effect.

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

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

    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 66% feathering flush and last year the same trees in mid-November averaged 23% feathering flush. As has been discussed next week will start an O.P. 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.

    If interested reply to all 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 approximatley 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 where 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, which 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

    8/10/15 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

    7/22/15 Counts are going up approximately 2-3 weeks post the regional application of Dimethoate or Imidan. We are starting our second oil spray with Agri-Flex, nutritionals, and copper were needed for canker. Also using Apta in some areas.

    The next regional application being discussed is another Organophosphate application going out in late August or early September.

    Contribution by Steve Farr

    6/25/15 Counts are low, this is 3-4 weeks post the regional application of Baythroid. The next discussed regional application is Dimethoate starting July 6th. 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

    6/14/15 Counts are rising. Most of the blocks with pressure are not in the aerial spray zones. Discussion for the next chma spray is July with Dimethoate. Thus should not be appling Organophosphate materials in the June summer oil spray.

    Like always, if interested reply to me or call Jerry Wise

    Contribution by Steve Farr

    5/28/15   Adults counts are low but rising and nymphs are high.  This is approximately 1 month post the regional application of Malathion. 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

    5/8/15 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.

    Contribution by Steve Farr

    4/21/15 Counts are down, but higher in this area than most of the other areas we scout. Also, the counts are lower than the same time last year. The hot spots were sprayed with Danitol by ground 3 weeks ago, all the area sprayed by air with Danitol 3 weeks ago are fairly clean. This is because the aerial application included most of the neighbors, thus the regional effect. The hot spots might not be groves not being sprayed, but growers spraying at different times. No new information being given here.

    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 me or call Jerry 334-898-7772

    Contribution by Steve Farr

    4/10/15 Most of this inspection was done previous to the Danitol applied by air or ground depending on block and participation with neighbors. Will see how the Danitol did on the next inspection. A lot of nymphs that are hard to control with pyrethroids.

    The next regional sprays being discussed is an O.P. material in July. Most growers are going next(late April early May) with a post bloom spray and an O.P. 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 O.P. 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.

But if enough participation, we will go by air for psyllids, and by ground for the other targets.

    Contribution by Steve Farr

    3/17/15   One site with adult psyllids found. Most of this area just got sprayed with Sivanto and nutritional. 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. 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 mid-March and April. This is the first time going out in March with labeled materials available to use during bloom. Will see if the usual spike happens at the next inspection in two weeks. CHMA’s are working towards 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, or Dibrom at night. This should help keep the populations low going into April.

    Contribution by Steve Farr

    2/24/15 O counts and high flush. This area had a Baythroid application applied by air or ground earlier in this month. Discussion are to use Movento, Closure, Exirel, or Sivanto (if you can get any) during bloom. Next regional application will be at petal fall and will be using Danitol.

    April is usually some of the highest counts of the year, and if you look at the yearly comparison spreadsheet 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

    2/10/15 Low counts and high flush. This area just had a Baythroid application applied by air or ground, started and finished this past week. Discussion are to use Movento, Closure, 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 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.

    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

    1/12/15 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, and could be in this area this week. The February application looks like an Organophosphate material, pending harvesting.

    Contribution by Steve Farr

    12/19/14 Counts are down, as well as flush. 2 weeks post an Organophosphate application.

    Next discussed regional application is Danitol in early January.

    Contribution by Steve Farr

    12/1/14 Counts are starting to rise, 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 me or call Jerry 334-898-7772

    Contribution by Steve Farr

    11/11/14 Latest scouting report. This is approximately 1.5 weeks post the regional applications of Baythroid. Counts are down finally, lowest we have had since before the bloom this year.

    The next regional application being discussed is the Danitol spray to be applied in early January. But with the amount of leaf drop, might need to put on something in December, especially if the trees start a flush because of all the leaf drop.

    Contribution by Steve Farr

    10/27/14   Counts are finally going in the right direction. Were there seems to be pressure now, is the blocks initially sprayed with the Envidor, Imidan, which is going on 4 weeks.  The blocks that had the high counts the last inspection, 2 weeks ago, had not been sprayed yet at that time, but have been now and the counts in these blocks are way down.  The flush is down as well, but way more than last year at this time.

    As has been discussed, a regional application of Baythroid started in this area today. Costs will be approximately $15.00/acre, applied at 10gl/acre. Jerry will have 3 planes available.

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

    Contribution by Steve Farr

    10/25/14 Counts are on the rise, again. Just finished a Imidan, Envidor, nutritional spray. As been discussed, the next regional application will start next week. An aerial application, Jerry Wise will be in this area next week applying Baythroid. If interested, reply to me or call Jerry 334-898-7772 Contribution by Steve Farr

    10/10/14 Pressure is on the rise. Most of the high counts are blocks not sprayed yet with Imidan, Envidor and nutritionals. We did do some perimeter sprays last week on blocks that were going to be sprayed at the latter interval with this application; also these blocks have neighbors with large counts. From this report, we did some good with the perimeter spray, but where the neighbors have high counts, the psyllids moved right back within 5 days behind the perimeter spray. Also, look at the flushing % for this year compared to last, probably another factor we have the highest counts for this time of year, in the last 4 years of scouting.

    The next regional application being discussed is a pyrethroid to go out late October or early November.

    Contribution by Steve Farr

    9/24/14 Counts are on the rise, this is about 3 weeks post the regional application of Chlorpyrifos. We are starting a ground application with Envidor, Imidan and nutritional.

    Discussions are for the next regional application to use a Pyrethroid in late October or early November.

    Contribution by Steve Farr

    7/16/14 Counts are low, 10 days after the Dimethoate regional application, mostly done by air. 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

    6/26/14 Discussion going forward is for a regional Organophosphate 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. Does have a 10 day REI. Jeff Summersill will be in this area and you can reply to all or call him 561-722-4502

    6/17/14 A few hot spots, mostly blocks that will be sprayed shortly with the first summer oil, nutritionals, Movento, and Imidacloprid.

    Discussions are to go with Dimethoate starting Monday June 30th.  Jerry Wise will have two planes going in this area.  Dimethoate has been very reliable material and is cost effective.  Does have a 10 day REI to work around.  If not already engaged, reply to me and will get information to Jerry or call Jerry at 334-898-7772

    Contribution by Steve Farr

    5/22/14  Fairly low populations, but starting to rise. 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 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

    3/28/14   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 next week, either by ground or air. Putting together the maps now, and will send out the information in the next two days.

    Jerry Wise will be doing this area and has 3 planes going for this regional application.  All the bees should be out by then, and will have to work around harvesting. The 24 PHI should help.  Either reply to me or call Jerry 334-898-7772

    Contribution by Steve Farr

    3/13/14   low counts of psyllids, approximately 8 weeks post the regional application of Danitol.   Also, most of this area has had a Malathion application with nutritionals in last 3-4 weeks.

    If you look at the report and see the grafts, you will see that some of the highest  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. Thus, will be discussing more as we get closer to petal fall.

    Contribution by Steve Farr

    3/13/14 As has been discussed, the counts are starting to rise. Next regional application, as has been discussed also, is just after petal fall. Danitol is the material growers wanted to use in this area. There will be several aerial applicators going just as soon as the bloom is finished.

    Contribution by Steve Farr

    2/25/14   0 counts of psyllids, approximately 5 weeks post the regional application of Danitol.  Also, most of this area has had a Malathion application with nutritionals in last 2 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. Thus, will be discussing more as we get closer to petal fall.

    Also, the second attachment is the aerial sprayed map showing what was done two weeks ago with Malathion. This is about 1400 acres with 6 different growers. This regional map usually is even better (meaning more participation) but harvesting earlies forced some of this area to be done by ground to work around the harvesting. Hopefully, this map will look more filled in with the Danitol in April.

    Contribution by Steve Farr


    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. 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.

    Jerry Wise will be going in this area next week, and is using Malathion, total costs are approximately. $14.00/acre.  If you have not already gotten engaged, please reply to all to be added to the spray list.

    Contribution by Steve Farr

    1/20/14 0 counts, approximatley 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.

    Contribution by Steve Farr

    1/12/14 All the ACP counts were in blocks in the DeSota city area, that have not been sprayed yet with the Danitol. The wind has delayed the two week intended application for this area into 1 extra week, and should be completed in the next 2-4 days. The goal was to be finished by the 15th.

    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 (petal fall) 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

    1/3/14 0 adults psyllids found.

    Starting the dormant Danitol this past week, but with the weather, not much got done. Plan was to finish all of the groves north of sebring up too Polk county by next weekend.

    Jerry Wise has 3 planes and if you have not already communicated, you can call Jerry at 334-898-7772 Costs are approximately 23.00 per acre, materials and application.

    Contribution by Steve Farr

    12/20/13 Scouting report for the Lake Letta and Memorial drive blocks. One hot spot in DeSota City area. For the Memorial drive grove area, plan was to spray this area during the week of December 30th with Danitol. If anyone needs help, reply back, and there will be some ULV contract applicators available to get the job done.

    Contribution by Steve Farr

    12/19/13 Counts are lower in this area than a lot of other areas we scout. The one hot spot is a block in the DeSota City area near the fire tower. This block did not get the surrounding participation as most of the other blocks, with the Mustang regional application in November, thus the high counts. 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.

    Thus growers are discussing to start the Dormant Danitol Regional applications on December 30th and to be finished by January 13th. Groves south of Hwy 98, going to Lake Placid, the plan was to start 1 week later, January 6th, to give the aerial applicators a chance to get the north end going.

    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

    12/2/13 Scouting report for the Lake Letta area. Counts are down, this is approximately 3 weeks post the regional application of Mustang. We have other areas the regional application of Mustang was not as effective. Could have been the weather (winds), material (Mustang is generally not a strong knock down) or pressure going into the regional application.

    The plan was to get too January to go with Danitol for the next regional application, but we are discussing going in December, possibly with an O.P. material, will be difficult with the minimum 5 day PHI. Will see how the scouting continues.

    Another problem, we see more flush than what we have seen for the same time of year (you can see this on our report for feathering flush %), thus more new generation of psyllids to control, especially in areas that have growers that are not participating with the sprays.

    11/13/13 0 adults found, some nymphs were found in blocks that are down in the DeSota City area. This area has not been sprayed yet with the aerial application, it should be done this weekend. This area, south of hwy 98 going to Lake Placid is in the Central Highlands CHMA area, and the plan for the CHMA is to start a regional application of Mustang at the end of this week.

    10/28/13 Counts are 0, this is behind a perimeter application of Imidacloprid done last week. If you look at the graft, you can see that thus far this year since August, the counts are much lower than the previous two years for the same time of the year. Pretty much the same program as the last two years, but we believe the counts are lower because of better participation with the regional CHMA sprays. We do not see this trend in other areas, and we do not have the participation in these other areas, like we have been able to get in this area.

    The next regional spray starts next Monday, November 4th, with Mustang. This should be done in two weeks. There will be 3 planes going in this area, and if you have not already contacted Jerry Wise, you can reply to all or call him at 334-898-7772

    10/17/13 Low counts, approximately 3-4 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.

    10/15/13 Counts are low, only blocks that any psyllids found, were in blocks that were not in a regional application, last month with Dimethoate. We are currently doing a perimeter spray with an Imidacloprid on all areas. Trying to keep populations down till November.

    9/27/13 Counts are low, one hot spot in a block at De Sota City area that was scouted before the aerial application of Dimethoate, will be back in this area with the scouts next week and see how it looks.

    Next planned regional application being discussed is November with Mustang.

    Contribution by Steve Farr

    9/5/13 1 counts in this area. 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)

    8/29/13 0 counts in this area. This has been mostly the same in all other areas, the last two weeks, but if you look at the summary and the grafts you can see this area has been fairly clean since mid-June. This area has been predomitily sprayed with regional applications by air, thus the reason for these results.

    8/15/13 - 0 counts in this area. 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 was not as high 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 neonics with the oils (imidacloprid or Actara materials).

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

    Contribution by Steve Farr

    8/6/13 Low counts in this area. 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).

    Contribution by Steve Farr

    7/22/13 0 psyllids. This is less than 1 week post the regional application of Dimethoate. If you compare this to the same time last year you can see these same areas are in better shape as far as counts go. The next regional application is being discussed to go after the second oil sprays in August, and should start around labor day or the first of September. Growers are looking at including a neonicotinoid with the oil spray in August.

    Contribution by Steve Farr


    7/22/13 The blocks on memorial drive with this report have 0 counts. This if the first time since February that the scouts did not fine at least one psyllids in this area. The next regional application is being discussed to go with another Dimethoate after the second oil spray coming up in August. Thus the Dimethoate application should start up around labor day or early September.

    Contribution by Steve Farr

    7/2/13 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 (Bairs Den) 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 Organophosphate material if Dimethoate is not used(Imidan, Lorsban,Dibrom, Malathion)

    Contribution by Steve Farr

    6/21/13 Lake Letta counts are low. Most of this area just had an application of Mustang done by air. Also Appling Movento with nutritionals and copper by ground now.

    6/14/13  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 going on.  Discussion is to go with Dimethoate in July.  Thus growers are not using any O.P. materials in their June summer oil sprays

    Contribution by Steve Farr

    5/30/13 Counts are down approximately 3 weeks post an Imidan application. 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


    5/16/13 Counts are low. Now in the process of spraying oil, agrimek, nutritionals and copper(where needed). Also, putting 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 O.P. Thus, will need to not use an O.P. material in June summer oil spray.

    Contribution by Steve Farr

    4/1/13 One psyllids found. It seems like the perimeter sprays at night have helped keep them down in this area. This report shows that last year they 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

    3/18/13 0 psyllids found. This is 1 week post a perimeter spray done by air or ground rigs at night. Discussions going forward are to start a regional application after petal fall and bees are moved out. Materials discussed are Delegate, O.P., or Mustang. Post-harvesting intervals are the driving force to decide which material can be used. A lot of groves have had the Pyrethroids (Danitol and Mustang) used the last two sprays, thus the need to use another chemistry such as Delegate or an O.P. material which has a minimum of 5 days post-harvest.

    Contribution by Steve Farr

    2/16/13 Psyllids counts are starting to rise. This is approximately 5 weeks after the Danitol regional spray. As has been discussed, with the amount of sporadic flush the past several weeks, the population of psyllids could be higher for this time of year, when comparing to previous years. We are starting a perimeter spray at night to slow down these increases, working towards getting to petal fall(whenever that will be) to start a regional spray with an O.P. or Pyrethroid. Growers are anticipating large increases in populations by the end of bloom, and the plan is to look at a regional application as soon as it can be coordinated after petal fall.

    Contribution by Steve Farr

    2/14/13 Psyllids counts are starting to rise. This is approximately 5 weeks post the Danitol regional spray. We have also finished a Portal, nutritional spray on the solid young blocks. As has been discussed, with the amount of sporadic flush the past several weeks, the population of psyllids could be higher for this time of year, when comparing to previous years. We are starting a perimeter spray at night to slow down these increases, working towards getting to petal fall(whenever that will be) to start a regional spray with an O.P. or Pyrethroid. Also, if you look at the report, in the Lake Letta area the scouts found 1 psyllids, which is a big area that had a good regional group spray with the Danitol, 8 growers spraying aprox 2000 acres and was done by plane or ground rigs, in about 3 days. Where they did find psyllids, in the East Sebring and Memorial Drive areas, there was little to no regional cooperation, thus the psyllids counts are higher.

    Contribution by Steve Farr

    2/4/13 1 adult psyllid and 0 nymphs found. This is approximately 4 weeks post the Danitol application. 63% flush, this is probably going to make it a challenge to keep low levels of psyllids through the bloom (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, with most if not 100% of these 5 year old solid set blocks closing in on full bloom.

    Contribution by Steve Farr

    1/16/13 Counts are 0, this is approximately 10 days post the regional application of Danitol. 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.

    Contribution by Steve Farr

    1/03/13 Where the few psyllids were found is in blocks that are in the process of being sprayed with Danitol. Most of this area was done aerially last week and where there was some pressure of psyllids from the last inspection, the counts are now 0 behind the aerial application. As has been discussed, the goal is to get this regional application of Danitol done by January 15th.

    Contribution by Steve Farr

    12/14/12 1 psyllid found with very low flush, this is approx. 4 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

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

    Contribution by Steve Farr

    10/29/12 Counts are starting to go up. 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.

    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 Psyllids counts are still down. This is approximately 3 - 4 weeks after the regional dimethoate application. Discussion going forward is to do a dormant pyrethroid regional application in early November.

    Contribution by Steve Farr

    9/20/12 There is a reduction in the overall psyllids pressure. This is approximately 10 days post the Organophosphate regional applications. We have not consistently seen this in all areas. This area had more participation than other areas and the results show it.

    Discussions are to look at early November for the first of two dormant sprays going with a pyrethroid.

    Contribution by Steve Farr

    9/5/12 Report for the Lake Letta area. There is an increase in populations and the perimeter is where they are the heaviest for this last survey. This is approximately 4 weeks after an Actara spray with oil and agrimek.

    The plan has been to go with a regional application in early September with an O.P. material and to be finished by September 15th.

    8/20/12 The Lake Letta area is showing low psyllids counts for this area. The Blumberg area is down at the Bears Den groves, south of Lake Placid. This area currently has the highest counts in all areas and is the highest we have had since we started scouting 1 year ago. This area is on the same program and being sprayed with the same materials, but we have not been able to coordinate a regional application as well as the Lake Letta area. One can see the results in the effectiveness of the regional sprays.

    The discussion has been to use an organophosphate material in September, after the oil sprays should be finished. Will be looking at the same methods as in the past with the aerial and ground ULV machines going at that time. Depending on rust mite pressures, some growers might have to go with ground applications to attack the mites and include an organophosphate material. Also, some growers are looking at another nutritional application, thus will be going with ground applications with nutritionals and an organophosphate material. This should happen before any harvesting concerns with the PHI problems with the organophosphate materials.

    This also could be the last regional spray attempt until November when the first Dormant applications begin.

    Contribution by Steve Farr

    7/17/12 This report is 2 weeks after a regional spray using an Organophosphate that was applied mostly by air. There is some scattered pressure around this area, especially on the perimeters.

    We, as well as most growers, are starting our second summer oil spray and are going into some heavy rust mite counts. Will be using different approaches to attack the mites. Some grower are using oil and an Abermectin material, some with sulfur, or Nexter. Most are looking at using Actara as their insecticide or Agri-flex.

    The discussion is to look at another regional application in September, after this oil spray. Looking at another Organophosphate application by air. This would work well before the harvest season gets underway. Thus all growers need to not use an O.P. material with their next oil, or summer spray if they want to participate with the September regional spray.

    6/26/12 A coordinated spray is planned for the Avon Park / Lake Letta CHMA. The application will begin on July 1st and continue through July 14th. The selected Mode of Action for the application is an Organophosphate. Please follow all label instructions for the material that is chosen.

    5/23/12 Avon Park Update. Many grower are considering late June or early July for the next coordinated spray , using an organophosphate material. The most recent ACP scouting reports shows a decrease of both nymphs and adults. The previous report showed a total of 62 nymphs and 40 adults. The current report shows a total of 1 nymphs and 4 adult. This scouting report was conducted approximately 3 – 4 weeks after an Abermectin, Imidicloprid, and Oil spray.

    Contribution by Steve Farr

    Counts in these areas are generally lower than other areas. The tapped psyllid counts did go up from the last inspection 3 weeks ago. This count is following the organophosphate spray done 2 to 3 weeks ago. The counts do show some pressure along the perimeter of groves and adjacent to groves not participating in the CHMA effort. The counts do show that the big block of Lake Letta that received an aerial application over the course of 2 days having a count of 0, except for the extreme east and west boundaries. This possibly shows the effect of getting a lot of acreage sprayed within a short window, again, most of the pressure on this inspection was found on the smaller blocks which were all sprayed with the same material and arguably with better coverage by ground machines as compared to aerial application, but not as a regional spray where all the blocks got sprayed in a short time frame. Obviously, the first of April is a hard time, as mentioned before, because of harvesting and all the different nutritional programs.

    Moving forward there should be more opportunity to complete a regional spray later in the summer, possibly during the July spray using an Organophosphate.

    We have started a post-bloom spray with the ground rigs using nutritionals, copper, oil, abermectin, and imidicloprid.

    4/3/12 From this you can see we are starting to find populations of Psyllids around the perimeters of the blocks.

    The plan that has been discussed it to go with an O.P. material after bloom.

    Some growers are doing a perimeter spray only at night to get to the petal fall period. Others are at petal fall and have started an application now with an O.P.

    Plan is to have an aerial application available after bloom. Will be starting next week. It 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, Dimethoate, or Malathion. Care must be given in considering the Post-Harvest interval.
