    8/30/16 Counts are high. Jeff Summersill will be available to do a regional application starting September 13th, two weeks from now. He will be applying Chlorpyrifos. Approximately $17.00 per acre

    Contribution by Steve Farr

    8/3/2016 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

    6/21/16 Counts continue to be high, higher for this time of year than the previous 4 years. The summary tab, bottom right shows the picture. This is about 3 weeks post the Dimethoate or Malathion applied by air or ground. Generally most are now going with summer oil, nutritionals, copper, and an insecticide. We are using Movento and Baythroid in most areas.

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

    Contribution by Steve Farr

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

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

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

    Contribution by Steve Farr

    4/23/16 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 and PFD sprays the last three weeks of March and the other half had Danitol with antibiotics the last couple of weeks. Between harvesting of Valencia and coordinating Antibiotics around the 21 day or 40 day PHI, depending on which one is used, there has been very little regional applications towards psyllids in most all areas, thus possibly the reason for the record adult psyllid counts everyone is seeing.

    Currently some growers are spraying the Post-Bloom spray and using a neonic. These are economical and have had some success, will also help with leaf minors.

    The next large regional application being discussed is an Organophosphate material to start after the harvest is completed, whenever that might be, but more than likely sometime in mid to late May. There will be an aerial application going in this area with Dimethoate, one of the most economical and effective applications we have seen.

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

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

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

    Contribution by Steve Farr

    2/24/16 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.

    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.

    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

    12/12/15 Counts are low, but higher for this time of year than the last 4 years. Might be a result of the optimum temperatures for reproduction of the darn psyllids as well as the amount of flush. In this area 74% of the trees had new flush, were the same trees last year in mid-December had 17%, and back in 2011 3%.

    The next regional application being discussed is the first of January with a pyrethroid. The 1 day PHI will help. Most growers are going by ground and will include nutrtitionals and possibly PFD materials.

    Working towards being completed by January 15

    Contribution by Steve Farr

    12/7/15 The next regional application will be in January with a pyrethroid. Most growers are discussing to go by ground and use nutritionals with this application.

    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 75% feathering flush and last year the same trees in mid-November averaged 16% feathering flush.

    As has been discussed this week will start an Organophosphate regional dormant application. Jeff Summersill will be in this area by the end of 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.

    Contribution by Steve Farr

    10/26/15 Counts are finally dropping, as well as the flush and rain. As discussed, the next regional application will start next Monday November 2, with a Pyrethroid. Jeff Summersill will be available to go by air in this area. If interested reply to me or call Jeff 561-722-4502

    Contribution by Steve Farr

    9/23/15 Counts are very high. We are seeing this in other locations as well. Possibly the abundant rainfall and the fairly large amount of flushing is contributing to the pressure. This is approximately 3 weeks post Imidan by ground or Dimethoate by air.  Also, in general, like other areas now and in the past, the aerial blocks in regional locations have lower counts than the ground sprayed blocks. All done at the same time, with the same rainfall, but better results 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. Has a 21 or 28 day PHI, depending on which material used.

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

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

    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

    7/13/15 Counts are down, approximately 2 weeks post an Organophosphate application, by air or ground, depending on the block and surrounding participation.

    Going forward, growers are looking at the second summer oil spray, and will add an insecticide with it, such as Actara or an Imidacloprid.

    The next regional application will be in early September with an Organophosphate material, thus if participating, growers should not use an Organophosphate material with the summer oil in July or August.

    Contribution by Steve Farr

    6/4/15  Counts are leveling about the same as the last scouting report.  This is approximately 3- 4 weeks post the Malathion and Abermectin, applied by air and ground, pending the block. Also about ½ the blocks were sprayed by air last weekend with Baythroid, and they are fairly low with adults.  Growers are going with summer oil now, and most are either using AgriFlex, Movento, or Micromite.

    The next regional application is early July with Dimethoate or another Organophosphate material. This application is approximately $11.50 per acre, including the Dimethoate.

    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.

    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

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

    Contribution by Steve Farr

    2/16/15 0 counts and high flush. This area just had a Baythroid application applied by air or ground. Discussion are to use Movento, Closure, Exirel, or Sivanto during bloom.

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

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

    Contribution by Steve Farr

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

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

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

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

    Contribution by Steve Farr

    10/20/14 Counts are on the rise. Most of the blocks with high counts were not sprayed yet with the Envidor and Imidan that is currently going out and should be finished by mid week.

    Discussions going forward have been to start a regional application of Baythroid next week. Jeff Sumersill should be in this area by the end of next week, pending weather. If you are interested in participating, reply to all or Call Jeff at 561-722-4502

    Contribution by Steve Farr

    9/29/14 Counts are steady, 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

    7/30/14 Counts are low in this area. Some other areas, we have seen much higher counts of psyllids. In general, the state scouting reports are also seeing higher counts than usual for July.

    Growers are discussing going in August with an oil, abermectin material, nutritional, copper where needed, and using either an Imidicloprid or Actara.

    The next regional application being discussed is an Organophosphate material in late August or early September. Jeff Summersill will be in this area for an aerial application if interested. 561-722-4502

    Contribution by Steve Farr

    6/18/14 Counts are down, this is approximately 2-3 weeks post the Mustang regional application. We are also finishing our first summer oil with Movento and Imidacloprid.

    Discussion are to start a regional application early July with an O.P. material.  Jeff Summersill will be doing an aerial application with Dimethoate at this time. Cost will be less than $12.00 per acre. Dimethoate does have a 10 day REI.  Also, Dimethoate has been one of the better materials for efficacy we have seen the last 7 years for adult psyllids.  Reply to me if interested or call Jeff at  561-722-4502.

    Contribution by Steve Farr

    6/17/14    Currently have a few hot spots in this area, these are blocks not able to fly with the Mustang two weeks ago, and are scheduled to be sprayed with ground rigs shortly.  We are finishing our first summer oil with Movento and Imidacloprid.

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

    Contribution by Steve Farr

    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

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

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

    Total costs, materials and application approximately 23.00 per acre.

    If interested reply to me

    Contribution by Steve Farr

    3/20/14 Attached is the latest report on psyllids for the north Frostproof area, up to Alcoma's old processing plant on hwy 60. From this you can tell the adults are starting to move. Per Dr. Rodgers, it is very difficult to go from 0 counts the last 3 months to this high, without fly ins from adjacent areas.

    As has been discussed for the last 2 months, Danitol will be used as the regional material, just as soon as the bloom is finished. Jeff Summersill will be flying in this area. Jeff (561)722-4502.

    Contribution by Steve Farr

    7/12/12 There is a coordinated spray taking place currently in the Babson Park CHMA. The regional spray will last through the end of the week. The selected material for this spray application is an Organophosphate.

    4/2/12 Steve Farr has indicated that the scouts have found some of the heaviest amounts of psyllids since we started the scouting program last summer. We are seeing this in all of the other areas as well The pressure is heaviest around the perimeters of the blocks. We did do a perimeter spray around some of the blocks that had psyllids the last inspection and these particular blocks were clean now, thus the perimeter spray gave us some control to get us to petal fall period we are in now.

    Have started today with Imidan, nutritional and copper (where needed, Canker and Fresh Fruit).

    Will have a plane in the north Frostproof area by the end of the week, if you have not already indicated, please reply to all and we can get the plane in on other growers as well.

    This is with Imidan and an adjuvant only and Imidan has a 7 day PHI.

    Update as of 3/14/12. We are starting to find them around the perimeters of the blocks in this North Frostproof area. The one area with the most found is next to a grove that has not been participating with the regional efforts. The plan that has been discussed it to go with an O.P. material after bloom. We are seeing similar finds in most of the other areas in the state. Some growers are doing a perimeter spray only at night to get to the petal fall period.

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

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

    2/27/12 – Psyllid scouting report
    Steve Farr provided the following information on 2/25/12. The psyllid scouting report for our North part of Frostproof up to Babson Park area. This is about 6 weeks after the regional application of Danitol. This is the second consecutive time the scouts did not find any psyllids in this area since we started the scouting program last August. Were we have checked in blocks that did not participate with the Dormant regional spray, we are finding low populations but can find some, and it is these adult psyllids that will be producing the nymphs that will become adults and will be foraging to adjacent groves in the next few weeks.

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

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

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


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

    The next coordinated psyllid spray will begin on Thursday, January 9, 2012 using a pyrethroid (i.e. Danitol or Mustang). If you are interested in participating in the application contact Chris Oswalt at 863-519-8677 ext. 108 or wcoswalt@ufl.edu.

    8/14/11 – Discussion going on about the next regional spray effort for Babson Park.
    Most growers are in the middle of their second oil spray and are using an imidicloprid, or Actara material, with the nutritionals, coppers, and miticides. Were we have not sprayed yet, and are 1 month out from the July regional spray with an O.P. material we are scouting these blocks and the psyllid counts are still low, other than some hot areas that are usually located next to a grower who is not concerned with the psyllid populations this time of year.

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

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

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

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

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