    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.

    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 561-722-4502

    2/9/16  Counts are low. As has been discussed, going now 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 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.

    1/22/16 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 timming 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 75% feathering flush and last year the same trees in mid-November averaged 20% feathering flush. As has been discussed next week will start an Organophosphate regional dormant application. Jeff Summersill will be in this area starting this weekend, with Alico (TRB and Bermont) going then BHG C&S grove, 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.

    10/26/15 Counts are low, but starting to rise. As discussed, the next regional application of a Pyrethroid will start Monday November 2. Jeff Summersill will be flying in this area, thus far Alico and BHG are in, thus will be doing 2000 acres+. If interested reply to me or call Jeff 561-722-4502.

    10/12/15 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

    9/24/15 Counts are fairly low, but higher for late September than they have been in the last 4 years since we started scouting for the darn things. This is approximately 3-4 weeks post a regional Dimethoate application done by air.

    We are seeing this in most all locations, record amount of pressure for this time of year. Possibly the abundant rainfall as well as the amount of flushing. The spray program and materials has not changed all that much.

    We are spraying with ground equipment for rust mites, nutritionals, and Actara.  The next regional aerial application being discussed is Baythroid to go out late October/early November.  If interested reply to me  or call Jeff Summersill, the pilot available to fly this area.   Jeff  561-722-4502

    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

    4/13/15 The graft shows the results of the Danitol, applied in the last 12 days either by ground or air, most of this area is aerial applied. The counts are lower than last year for the same time period, the only difference was last year no applications during march, this year Exirel was used during the bloom. Danitol was used both years at the same time, rate and method of application in early April.

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

    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.

    3/26/15 Numbers are low, but starting to climb If you look at last year's graft, you can see what the trend has been for the upcoming April counts.

    Discussions have been for the next Regional application to be with a pyrethroid. And to start as soon as the bees and bloom are gone. Danitol has been the choice of the best material for this high pressure application timing. Some growers are looking at getting started next Monday, March 30th. Jeff Summersill will be doing an aerial application of Danitol in this area starting the first of next week, pending weather, if interested reply to me, or call Jeff at 561-722-4502

    3/6/15 1 adult psyllids found. Most of this area just got sprayed with Exirel or 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 (if they got any). This should help keep the populations low going into April.

    2/17/15 Low counts and high flush. This area just had a Baythroid application applied by air or ground. Discussion are to use Movento, Closure, Exirel, or Sivanto during bloom.

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

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

    10/20/14 Counts are finally going down, but flush is slowing down as well. If you look at the report the block with most of the pressure was scouted before this month's application of Envidor, Imidan and nutritional. It is being sprayed today.

    Next planned regional application being discussed is to go with a pyrethroid. Jeff Sumersill will be flying in this area starting next week. If interested in participating reply to me, or call Jeff 561-722-4502. Growers are looking at Baythroid at 10gl/acre. Cost will be approximately $15.00/acre.

    6/13/14 Discussions are looking at a Dimethoate application late June or Early July. Jeff Summersill has been flying some of the groves in this area the last 1-2 years. If interested, reply to me or call Jeff at 561-722-4502

    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.

    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. Jeff Summersill will be doing a regional aerial application in this area in November. You can contact him direct and his information is below.
