    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.

    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

    5/2/16 Counts have dropped but still 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 two months, and has something to do with the high psyllids counts across the state.

    Discussion going forward is for an Organophosphate application mid to late May, after the Valencia crop is harvested. Jeff Summersill will be in this area with an aerial Dimethoate application for approximately $12.25/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. CHEMA sprays are going to be less available this year and growers might/should consider to take advantage of them when they can.

    2/26/16 Counts are 0. This is about 2-3 weeks post the Pyrethroid sprays. The March regional spray used last year, was mostly done by ground, 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.

    2/10/16 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.

    1/25/16 Counts are low. All 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 timing and PFD concerns, as well as nutritional needs, this application will more than likely be done by ground. One thing that could change is a spike in psyllid counts/pressure and the aerial application would more than likely be needed.

    Contribution by Steve Farr

    1/7/16 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.

    12/16/15 Counts are low but high for this time of year, we see this in most areas with this area having 70% flush currently and last year at the same time with the same trees, 17% 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 only block sprayed by ground (40 acres) had half the adults found (15) compared to the aerial blocks 450 acres, with the same amount of adults (15).

    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

    11/30/15 Count are low but higher than usual for this time of year. This is approximately 3-4 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 41% feathering flush and last year the same trees in mid-November averaged 22% feathering flush.

    As has been discussed next week will start an Organophosphate regional dormant application. Jeff Summersill will be in this area starting this week. He will be appling 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.

    10/13/2015 Counts are finally down, this is behind Actara, about 1-2 weeks. Also, flush is down to help and the rainfall has dropped off some.

    Next regional application being discussed is a pyrethroid in early November.

    Contribution by Steve Farr

    9/25/15 Counts are up. seeing this in most locations. Generally higher or highest we have seen for this time of year, going back 4 years since we started inspecting. Possibly the abundant rain and considerable amount of flush, might be facilitating the darn things.

    This scouting is approximately 3-4 weeks post the Dimethoate applied by air, or Imidan by ground.
    Also, this last application, all the groves were sprayed by air (approximately 450 acres) with Dimethoate other than one 40 acre block, which was done by ground with Imidan. The total count of adults psyllids found was 139 across all the block, but of these 71 were found in the one 40 acre block sprayed by ground, or about 50%. This block is not adjacent to growers who are not spraying. Point is the regional application works more effectively, even when not a lot of participation, like the last one done with dimethoate. Also, who can spray for $6.50/acre with ground rigs?

    We see this across the 5 counties we inspect.  With everyone trying to tighten budgets, and if interested in managing psyllids, which can be attributed to a lot of our production problems, can anyone do a better and cheaper job than regional applications by aerial sprays?

    We are going now with Chlorpyrifos by ground with nutritionals and a miticide where needed. Could coordinate an aerial application if other growers were interested, would need to get done in the next two weeks. If interested, reply to me.

    The next regional application after the Chlorpyrifos being discussed is Baythroid in late October or early November, will cost approximately $12.50 per acre for materials and application.

    Contribution by Steve Farr

    9/9/15 Counts are down. These blocks were sprayed 10 days ago, by air with Dimethoate ($12.00/acre), or by ground with Imidan ($25.00/acre). The most psyllid pressure is in blocks sprayed by ground. We have seen this in other areas, where the aerial, REGIONAL sprays are out performing the individual ground applications. In this case there is a difference in materials used, that might have some influence on the efficacy of the controls as well.

    Open for discussion on the next regional application, probably with a Pyrethroid, preferably when things cool down, whenever that might be.

    Contribution by Steve Farr

    8/21/15 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 or Apta with it. Looking at an Organophosphate regional application to starting the end of next week. Jeff Summersill will be going in this area and if interested reply to all or call Jeff 561-722-4502

    Contribution by Steve Farr

    7/23/15 Counts are going up approximately 2-3 weeks post the regional application of Dimethoate or Imidan. Growers are starting their second summer oil, some using Agri-flex, Apta, ect.

    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 down. This is approximately 3-4 weeks, post the regional application of Baythroid. Discussion of a Dimethoate to go on early July, or another Organophosphate material if the 10 day REI cannot be worked out. Jeff Summersill will be in this area the week of July 6th. Total cost will be approximately $12.15 per acre. If interested reply to me or call Jeff 561-722-4502

    Contribution by Steve Farr

    6/4/15  Counts are high.  As has been reported, Jeff Summersill will be in this area tomorrow with Baythroid. Most growers are spraying summer oil with Abermectin, Micromite or Movento.

    The next regional application being discussed is Dimethoate in early July. This will cost approximately $11.50 per acre. If interested reply to me.

    5/28/15  Counts are fairly low, the heaviest psyllids population  block was not included in the regional aerial applications, done last month with Malathion, but did receive the same application by ground that the other blocks received by air, but the aerial blocks  were done regionally with some neighboring growers. Go figure.

    Jeff Summersill will be in this area next week with Baythroid, approximately $11.00 per acre costs of application and materials.  If interested, reply to all or call Jeff 561-722-4502

    Contribution by Steve Farr

    4/22/15   Counts are maintaining very low.  Also, the counts are lower than the same time last year. This area was sprayed with Danitol by air of ground approximately 3 weeks ago.

    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 Jeff 561-722-4502

    Contribution by Steve Farr

    3/9/15 1 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

    2-19-15   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, hopefully not tomorrow night) 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

    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.

    Jeff Sumersill will be going in this area sometime by the end of next week. The cost for 3.2 ozs/acre of Baythroid, Adjuvants, and application will be less than $11.00 per acre.

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

    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. Jeff Summersil is available if anyone needs applications by air, and could be in this area next week.

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

    11/26/14  Counts are starting to rise. Approximately 4 weeks post the last regional application of Baythroid or Imidan(pending the grower).  Jeff Summersill will be in the area next week going with Malathion by air. Cost approximately $14.00 per acre. 7 day PHI, thus will have to work around harvesting.

    If interested, you can reply to me or call Jeff at 561-722-4502

    The next planned regional CHEMA spray will be the Danitol application in early January.

    Have a great Thanksgiving

    11/11/14 Latest scouting report. This is approximately 1.5 weeks post the regional applications of Baythroid or Imidan.

    Counts are down in general.

    The next regional application being discussed is the Danitol spray to be applied in early January.

    Contribution by Steve Farr

    10/22/14 Counts are on the rise, again. Just finished a Imidan, Envidor, nutritional.

    As been discussed, the next regional application will start next week. An aerial application, Jeff Sumersill, will be in this area next week applying Imidan or Baythroid. If interested, reply to me or call Jeff 561-722-4502

    Contribution by Steve Farr

    10/6/14 Counts are going up. In the process of spraying with ground rigs with Envidor, and Imidan, with nutritionals.

    Plan for the next regional application with a pyrethroid in late October, early November.

    Contribution by Steve Farr

    9/4/14 Counts are on the rise. We are seeing this in many areas we scout. Approximately 2-4 weeks post an Agri-flex application. We are currently applying an Organophosphate material, Chlorpyrifos by air.

    The next regional application being discussed is a Pyrethroid application in late October or early November.

    Contribution by Steve Farr

    6/24/14 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. 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

    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.  Jeff Summersill will be flying in the bears den 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

    4/16/14   Counts are down, approximately 2 weeks post a Danitol spray, some of these blocks done by air where there was participation and some done by ground at the same time. Interestingly, the aerial blocks done with adjacent neighbors have less pressure than the blocks done by ground, independently.

    Growers are discussing going with an Organophosphate material with their post bloom sprays next.

    The next planned regional aerial application is July with an Organophosphate material, such as Dimethoate for 11.00 per acre.

    Contribution by Steve Farr

    3/27/14  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.

    Jeff Summersill will be going in this area first of next week.  All the bees should be out by then, and will have to work around harvesting. The 24 hour PHI should help.

    Either reply to me or call jeff at 561-722-4502

    Contribution by Steve Farr

    3/6/14   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.

    2/4/14 0 counts of psyllids, approximately 3 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 blooms 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 were growers are trying to spray for them. We do have some new materials that might help during this time, that are supposed to be effective against the psyllids and not on the bees.

    Also, growers are discussing going with a regional application of a Pyrethoid in early April or late March, pending on when the bloom is finished (again, when will that be). This is with the anticipation that they are going to spray sometime in February or March with another chemistry, such as an O.P. material mentioned above or the new Closer material. This will enable them to break the cycle of the Danitol just used in January by most growers in the state.

    12/30/13 Our scouting report is starting to show an increase in psyllids. Not surprising with all the flushing going on. This is approximately 6 weeks since the Mustang regional application done in November. As has been discussed, the Danitol dormant regional application is to start Monday January 6th for the bears den area. Applications should be done in a two week window.

    At this time, no aerial applications are being scheduled. Growers are going with ground rigs, some are having to spray for rust mites as well, and most want to include some type of nutritionals.

    The next regional application should be at petal fall (whenever that is) and either a Pyrethroid or Organophosphate material to be used. Most growers think they will spray again in February, before march and will use the Organophosphate material then, thus they can rotate back to a Pyrethroid in April and this will help with harvesting and the 1 day PHI.

    12/12/13 Latest report, counts are down, only pressure is the Stewart road area, we sprayed Surround and Malathion two weeks ago on this block. The adults are down, but still finding nymphs on some of the feathering flush. Unfortunately, there might be more flush coming with the weather we are having.

    This being said, at a grower meeting Tuesday, the CHMA plans were discussed to look at January 6th being the starting date for growers to apply the dormant Danitol. This is preliminary, but all agreed that the more participation and the closer the applications can be coordinated, the better the results. The thought was to attempt to spray everything south of Hwy 98 to Venus in one week. There will be more correspondence coming on this and the date might shift 1 week earlier or later.

    Jeff Summersill will again be available and will be doing many of the blocks in this area, if interested you can contact him directly.

    11/6/13 Most recent scouting report, from this you can see the same hot spot that we have been fighting for the last several months. This is post an Imidicloprid spray done on the perimeters two weeks ago. This area, as well as all the area in the Bears Den is starting a regional application of Mustang tomorrow. Currently, there is over 4000 acres participating in an aerial application to be done in the next 3-4 days, pending weather.

    Contribution by Steve Farr

    10/24/13 Counts are low. 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. Jeff Summersill will be aerial applying in this area, starting around November 9th. His contact information is below:

    9/30/13 Counts are 0 behind the regional application of Dimethoate done 3 weeks ago by air, except for one area, that has all of the counts, and this area was NOT done regionally by air. This area had some participation with a few growers trying to coordinate with ground rigs and using Dimethoate, but the timing between the applications took 9 days, were the other areas done by air were done in two days. Might have something to do with the differences in the counts.

    9/12/13 Counts are on the rise, this is approximately 3 weeks post the Agri-Flex application. This is also the highest counts we currently have in 5 counties. There is currently a regional application of an Organophosphate material being applied in this area and will see how the counts look in 2-3 weeks.

    There has been more discussion in this area than in the past to participate with the regional applications. The next general sprays being discussed is to go in November, with the first dormant Pyrethoid spray.

    There is no reason why an aerial application could not be done from hwy 60 to venus.

    8/28/13 0 counts, first time the scouts did not find any psyllids in this area since January.

    This is approximately 2-3 weeks post the oil and Agri-flex application.

    Discussions are that most growers are finishing their second summer oil spray and are looking at a regional application of an Organophosphate material. Where the 10 REI can be worked out, Dimethoate has been one of the favorites because of its effectiveness and economics.

    Jeff Summersill, a contract aerial applicator (561-722-4502), will be available to do a regional application if other growers are interested. Costs should be less than $12.00 per acre. Growers are discussing to start this application September 9th.

    8/14/13 Counts are low, the blocks that have pressure are in the process of getting sprayed with the second summer oil spray with Agri-flex, copper, and nutritionals.

    In other areas, were there has been regional applications done by aerial and/or ULV, we have had 0 psyllids counts, some of these have had 0 counts since May. The second attachment is the report for an area consisting of more than 5000 acres with 10 different growers participating. This area is northeast of Avon Park.

    In these areas, growers are planning the next regional application to start the middle of September. An O.P. material will be used, and this should work with the higher PHI problems, in that very little harvesting will be going on at this time. We will more than likely be using a plane contractor to put out Dimethoate in the Bears Den area, and if anyone else would like to participate, reply to all and we will get coordinated.

    6/28/13 Plenty of psyllids pressure in the Bears Den area (the Blumberg attachment). If you compare this Blumberg report to the Section 35 report you will see the difference in counts. Same inspectors inspecting the same way. Also the same materials were sprayed two weeks ago (mustang), Section 35 area was done mostly by air WITH neighbors with good regional effect, vs. ground rigs at night with no participation in the Bears Den area.

    Most growers are discussing about using an Organophosphate material between their two summer oil sprays. In the north Highlands county area, there will be a regional spray of Dimethoate going, starting July 8th.

    Contribution by Steve Farr

    6/12/13 This is the highest counts in all the different areas we scout in the state. Same materials sprayed at the same time, just very little coordination in this area. Most growers are discussing going with a regional application of Dimethoate in July.

    Contribution by Steve Farr

    5/24/13 Counts in this area are currently the highest we have. In the process of finishing an oil, agrimek, nutritionals and copper (where needed). Also, have included Imidan by ULV done two weeks ago. 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

    5/9/13 Psyllids counts are up, this is one of the highest areas we scout in. This is post 3-4 weeks behind a Mustang/nutritional spray. In most other areas, treated with the same materials and same time, BUT with a regional application by air, we do not have these high of numbers. If you take the time to look at the state information for cycle 30 you will see that Bears Den CHMA area has some of the highest counts in the state, thus the reason we see these numbers in our scouted blocks, as well with the lack of regional cooperation. We started our post bloom spray last week with agrimek, oil, nutrition, and copper were we have potential canker problems. We also started last night a ULV application with Imidan, which will finish tonight, but the ground sprays with the agrimek will take 4 weeks, thus the reason to bring in the ULV and hopefully get these populations down.

    Looking forward, June is being discussed that it would be hard to coordinate a regional application, with all the different summer oil programs and possibly some harvesting still being done, if any fruit is left from the drops. July has had a lot of success with a regional application of an Organophosphate material between the two summer oil sprays and after all harvesting is finished. If this area could generate enough interest, this could be worked out to be done by air at less than $10.00/acre!!! Again, this has shown the best way to manage the insect that is creating all of our greening problems.

    3/27/13 Psyllids scouting for Bears Den area. This is after two night time perimeter sprays the last 4-5 weeks. Pressure is a little less than this time last year. Based on the history from the state, we are going into the highest pressure for psyllids in the next few weeks. Discussion of most growers is to start after petal fall and bees are gone (whenever that will be) and use either a Pyrethroid or O.P. Harvesting REI is making the O.P. materials difficult, but some growers have used a Pyrethroid (Danitol or Mustang) the last two sprays.

    Contribution by Steve Farr

    2/10/13 Psyllids counts starting to rise. This is approximately 4 weeks post 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.

    Contribution by Steve Farr

    1/29/13 0 counts of adults and 2 nymphs found. This is approximately 2 weeks post the Danitol application. 72% 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 are starting today 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

    1/12/13 Psyllids counts are down. Finishing the Danitol dormant spray. Notice the amount of flush compared to same time last year. 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

    12/28/12 Unfortunately, the psyllids pressure is on the rise. Also increase in flush (60% of the trees inspected had feathering flush, were last year at this same time 24% had flush) which usually means the more flush the more psyllids. As has been discussed, with all the defoliation last month and with the warmer early December, 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 this week, because of harvesting. The Danitol does have a 24 hour post-harvest. The goal is to finish by January 15th. With the amount of flushing (particularly on the sick greening trees, some of these are already in early bloom stages), IFAS recommends to get this dormant spray applied as quickly as possible before the psyllids have a chance to multiply.

    12/12/12 This inspection they found 2 adult psyllids on our young solid planting. Also the %flushing went up to 23%, which is the highest we have seen in any location in the last 3 weeks. But most of the flushing is on the young blocks. The plan has been to go with a regional application of Danitol in early January. With all of the defoliation last month and the weather conditions, growers might see more significant flushing in older plantings, and this will make the dormant sprays even more important to get a head start on the psyllids populations and get a good knock down before they start reproducing, thus the importance to plan on starting the sprays in early January.

    Contribution by Steve Farr

    11/27/12 0 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

    10/26/12 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. Some growers are starting next week because of high pressure now. Per Lake Alfred, if possible, need to try and apply the Pyrethoid after the fall sporadic flushing is over, so that ADULTS psyllids are all you are trying to control. We have all seen how difficult it is to control eggs and nymphs, thus the reason to get the dormant spray on after the flush. Frank Youngman will have several ULV machines going at night in this area and can be reached at 863-441-1164.

    Contribution by Steve Farr

    10/11/12 Psyllids counts 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

    9/17/12 You can tell the blocks that have been sprayed with the O.P. materials vs the ones that have not. Weather has held up this application or all the blocks would be done. Interestingly, in most all other areas were we have not finished this O.P. spray, we do not find the kind of pressure we have in this area. As stated be before, we have been able to coordinate a better region application in these other areas and it is showing a difference in these scouting reports.

    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).

    Contribution by Steve Farr

    8/22/12 The Ft. Meade area is showing a 0 psyllid count for this area. The Blumberg area is down at the Bairs 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 Ft. Meade area. One can see the results in the effectiveness of the regional sprays. The discussion has been to use an O.P. 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 O.P. material. Also, some growers are looking at another nutritional application, thus will be going with ground applications with nutritionals and an O.P. material. This should happen before any harvesting concerns with the PHI problems with the O.P. materials. This also could be the last regional spray attempt until November when the first Dormant applications begin. Contribution by Steve Farr 8/17/12 The report in the Bears Den area shows significantly higher psyllid counts. These counts are currently higher than anywhere else we scout (10 areas in 5 counties). Also these are the highest counts we have seen in these blocks since the scouting program was started. The blocks with the highest counts are in the process of being sprayed with oil, agri-flex, and nutritionals. The Section 35 area report is in the north Avon Park area. As you can see, these are better counts. Some of these blocks have not been sprayed as well, but still have low levels of psyllids. The significant thing to note is that this Section 35 area has had more success with growers cooperating with the regional applications. The discussion has been to look at a regional application in early September with an Organophosphate material. What we have seen that works the best so far, is when growers can coordinate an aerial application. Will see if that could be available for the Bears Den area.

    Contribution by Steve Farr

    7/27/12 This is post 3 weeks the attempt of a regional application of an O.P. material. This area is the highest we have found for psyllids pressure out of the 10 other areas we scout in 5 different counties. These scouting reports are done by the same 3 scouts for all the areas and are done the same way, thus some kind of consistency for the reports.

    Growers are discussing attempting another regional application after their second summer spray, which will be late August or early September. This will be with an O.P. material again, thus growers are not using an O.P. material with their summer oil sprays. Most are going with oil and agriflex materials. Most are fighting the building rust mite problems we are seeing. Some are using another miticide, but adding actara, thus, still using a neonicotinoid material for psyllids and leafminors.

    \We are spraying these heavy areas of psyllids with Agri-flex and oil now and will see how they look in the next inspection in 2-3 weeks and will forward the information out.

    Contribution by Steve Farr

    6/26/12 A coordinated spray is planned for the Bairs Den 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.


    5/3/11 – Latest psyllid scouting reports for Highlands county now posted


    5/23/12 Bairs Den 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 200 nymphs and 19 adults. The current report shows a total of 0 nymphs and 1 adult. This scouting report was conducted approximately 2 – 3 weeks after an Abermectin, Imidicloprid, and Oil spray.

    Contribution by Steve Farr

    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.
