    4/28/16 CHMA Participants,

    We are looking to do an aerial application for the month of May. We would like to see who all would be interested in participation of the aerial spray as well as who is spraying with ground rigs. We haven't decided on the spray materials or the start date yet, we are looking for everyone's input so we can maximize participation. Please contact Keith Farr or myself if you are interested or have any recommendations.

    Thanks,
    Conner Davis

    12/15/15 Hardee County will be conducting a coordinated CHMA spray starting tomorrow. The mode of action for this spray will be a neonicotinoid (Imidacloprid or Thiamethoxam).

    There will be an airplane available if you would like to use it. The airplane application will cost $11.10. If you would like to use the plane contact Keith Farr at kmfarr@embarqmail.com or 863-781-1464.

    Any application method is acceptable and you should select the application method that best fits the needs of your grove.

    11/13/15 The Hardee County CHMA leaders meet this morning to discuss the upcoming dormant ACP control sprays. For December the recommended mode of action is an Organophosphate, but if harvesting or re-entry is a concern a Neonicotinoid could be used instead of the Organophosphate. In the January the recommended mode of action is a Pyrethroid.

    6/30/15 In an effort to stay ahead of the psyllids we are planning for another aerial application for the week of July 15th. For this application we will be using Dimethoate (REI-10 day; PHI- 15 days) and Clearsurf 90 as a surfactant. The cost is $12.00 per acre (Materials $5.50/ac, Application $6.50/ac). We would encourage everyone to spray around this time if at all possible, whether that be with the airplane, ground rigs or any other methods. Please let myself of Keith Farr know if you are interested as soon as possible, or if you have any other questions.

    5/22/15  The next coordinated spray for the Hardee County CHMAs will be the week of June 1st.   The Mode of Action for this spray will be a Pyrethroid (Mustang, Danitol, Baythroid).   Growers are free to choose the material they prefer.

    There will be an airplane available to aid in the application of this spray.  The total cost of the aerial application will be $10.55.  If you would like to utilize the airplane contact Keith Farr, kmfarr@embarqmail.com.  The application method for any CHMA spray is decided by each grower.  All spray application methods are acceptable (aerial, speed sprayer, low volume, fogging).  Please choose the appropriate method for your grove. 

    4/17/15 The Hardee County CHMA leaders met this morning to discuss the upcoming CHMA activities. It was decided that the next coordinated spray will take place at the end of May 2015. The Mode of Action for that spray will be an Organophosphate (Dimethoate, Imidan, Lorsban). There will be an airplane available to aid in the application. If you want to utilize the airplane please contact Keith Farr.

    2/20/15    O  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.

    1/30/15 The Hardee county CHMA leaders met this morning to discuss the next course of action in the 4 Hardee county CHMAs. The next spray will be the week of February 9th. The mode of action for this spray will be a pyrethroid (danitol, mustang, baythroid). Growers are free to choose the material that they like. There will be an airplane available to aid in the application. The airplane will be applying Baythroid at $9.75 per acre. If you want to use the plane contact Keith Farr at 863-781-1464 or kmfarr@embarqmail.com. Growers are free to use the application method they prefer (aerial or ground application).

    12/3/14 The next CHMA coordinated spray for the Hardee county CHMAs will begin the week of December 15th. The mode of action for this spray will be a pyrethroid (mustang, danitol, baythroid). Growers are free to use any pyrethroid material they prefer and there preferred method of application (air or ground).

    There will be an airplane available to aid in the completion of the spray. The airplane will be applying Baythroid and a surfactant at a cost of $9.75/acre. If you would like to utilize the airplane contact Keith Farr at 863-781-1464 or kmfarr@embarqmail.com.

    10/6/14   The Hardee county CHMA leaders met Friday morning to discuss the final CHMA activities for 2014.  The next coordinated spray should begin on October 15th and the mode of action will be an organophosphate (Imidan, Dimethoate, Lorsban).  The first of two dormant sprays will be in December and the Mode of Action will be a pyrethroid (Mustang, Danitol, Baythroid). 

    The group also developed a coordinated spray plan for 2015.  The 2015 spray plan is below (page 2).  As the time for each 2015 coordinated spray gets closer, a more exact date will be determined.  Success in the coordinated sprays is dependent on grower participation.  The 5 sprays outlined in the coordinated plan are applications that have been identified to be critical for suppression of psyllids.  

    Participating in the coordinated sprays requires making the spray application during the established timeframe and using the suggested Mode of Action (chemical class).  The insecticides for each Mode of Action are listed in the comments section of the spray plan.  Growers are free to choice which insecticide they want to use within the selected Mode of Action.  Any other material that is added to the spray mixture is solely up to each grower. 

    The application method for any of the coordinated spray is a decision for each grower to make.  For each of the sprays listed below there will be an option for aerial application.  If you would like to utilize the aerial application in your grove, make arrangements with the CHMA leaders.  Participation in the coordinated sprays does not mean that you must use an aerial spray.  Ground application of these sprays is acceptable and in some case may be the only option.  Use the application method you feel most comfortable with. 

    9/5/14 The Hardee County CHMA leaders met this morning to discuss the upcoming dormant sprays for psyllid control. It was decided to conduct the 1st dormant spray at the beginning of November and the 2nd dormant spray will be scheduled for January.

    The insecticide mode of action for both dormant sprays will be a pyrethroid (Mustang, Danitol, Baythroid). Growers are free to choice any pyrethroid insecticide they prefer. There will be an airplane available to aid in the dormant spray applications, if you would like to utilize the airplane contact Keith Farr.

    8/8/14 We are planning on the next CHMA application for the week of August 18th. This application we are using Imidan (organophosphate) and this product has a 24 hour REI. The cost is $16.00 per acre, which includes materials and the application. Please let myself or Keith Farr know if you are interested or have any questions.

    Contribution by Conner Davis

    6/18/14 Counts are down, this is approximately 3 weeks post an aerial application of Mustang, and a ground application of Movento, Imidacloprid, and Oil.

    Contribution by Steve Farr

    6/16/14 Due to weather conditions the aerial spraying was delayed but we are starting today, moving from east to west. Please remember there is a 10 day reentry.

    Contribution by Jahna Davis

    5/28/14 We are planning the next CHMA application for the second week in June. We are using Dimethoate, this product has a 10 day REI. The cost per acre is $12.00, this price includes all materials and the application. Please let myself or Keith Farr know if you are interested as soon as possible. Also, if you have any question feel free to contact me or Keith.

    5/5/14 The Hardee CHMA leader met today to discuss the next course of action for the 4 Hardee County CHMAs. The recommendations are to use a Neonicotinoid for psyllid control in the month of May. The next coordinated spray will be in June using an Organophosphate.

    Please follow all label instructions for any material that is used.

    3/31/14 Psyllids are on the move. In some areas we are finding record amount of adults. Usually this is in areas where we continuously find them anyways, which is areas that have not been able to coordinate many/any regional sprays.

    Per Keith, Danitol/Mustang is the choice and should be finished by air or ground asap, after bloom and bees are gone (most areas the bloom is gone).  We sprayed Danitol by air today at the Roseto grove.

    Contribution by Steve Farr

    3/6/14   Attached is our scouting report for the Roseto grove in the Ona area.  0 counts of psyllids, approximately 8 weeks after 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).

    Per Keith, the next important regional application will be just after petal fall, with Danitol/Mustang, which has a 1 day PHI that should help with the Valencia harvest.

    Contribution by Steve Farr

    1/31/14 The Hardee County CHMA leaders met this morning to discuss the next planned coordinated spray. The growers agreed that a Pyrethroid (Danitol, Mustang) will be utilized for the month of February. Please follow all label instructions the material that is used, paying close attention to PPE requirements, re-entry intervals, pre-harvest intervals, and bloom restrictions.

    11/4/13 The Hardee County CHMA leaders met today to discuss the upcoming dormant sprays. It is recommended that grower utilize a Pyrethroid (Danitol or Mustang) for the first dormant spray during the month of November. The second dormant spray will take place in January and will also be a Pyrethroid. If a spray is needed between the first and second dormant it is recommended to use a material that is not a Pyrethroid.

    As always please follow all label instructions for the insecticide that is chosen, paying close attention to pre-harvest intervals, re-entry intervals, ppe requirements, and application rates.

    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.

    Contribution by Steve Farr

    9/11/13 The 4 Hardee county CHMAs met today to decide the next course of action in coordinated psyllid control. It is recommended that growers use a Pyrethroid (Danitol or Mustang) in the October – November time frame.

    Please follow all label instructions for any material that is used, paying close attention to PPE requirements, Pre-harvest interval, Re-entry interval, and application rates.

    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.

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

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

    Contribution by Steve Farr

    8/14/13 O counts, this is approximately 3 weeks post an aerial application of dimethoate. We are in the process of spraying, by ground, the second summer oil with Agri-flex and nutritionals. Will be looking at another regional aerial application in Mid-September with Dimethaote. This cost less than $11.00 per acre. If anyone else would like to participate, then reply to all and we can get coordinated.

    Contribution by Steve Farr

    8/2/13 The Hardee County CHMA leaders met today to discuss the next course of action for coordinated psyllid control. It is recommended that growers use a pyrethroid (Danitol, Mustang) at this time for psyllid management. Following this the next coordinated spray will take place in the September – October time frame. The Mode of Action for this spray will be an Organophosphate (Lorsban, Dimethoate, Imidan). The exact dates for the application have yet to be determined, but once a time frame has been established the dates will be posted to the CHMA website.

    Please follow all label instructions for any material that is used, pay close attention to PPE requirements, Pre-harvest interval, Re-entry interval, and application rates.

    7/2/13 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)

    4/3/13 The Hardee County CHMA leaders met this morning to discuss the upcoming Asian Citrus Psyllid management plan. It was decided that growers should apply a Pyrethroid (Danitol or Mustang) and Spirotetramet once petal fall as occurred. The next spray will occur in the months of May – June using an Organophosphate. The last planned spray will take place in June – July using a Neonicotinoid and Abamectin.

    The spray plan is subject to change. If there are any changes the new spray recommendations will be posted to the Hardee County CHMA websites.

    1/7/13 The Hardee County CHMA's are in the process of conducting the 2nd dormant spray for Asian Citrus Psyllid control. The application will begin in early January and needs to be complete as quickly as possible. The selected Mode of Action for this application will be a Pyrethroid (Danitol or Mustang). Please follow all label instructions for the material that is chosen.

    12/28/12 Unfortunately, the psyllids pressure is on the rise. Also increase in flush (25% of the trees inspected had feathering flush, were last year at this same time 5% 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.

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

    12/3/12 The Hardee County CHMA's met to discuss the next planned coordinated psyllid control spray. The decision was made to schedule the next coordinated spray for early January. The selected Mode of Action for this application will be a Pyrethroid (Danitol or Mustang). Please follow all label instructions for the material that is chosen.

    11/28/12 0 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

    11/21/12 ACP counts and flush is down. This is 2 weeks after the regional Mustang application. Next application being discussed is the Danitol dormant spray in January

    Contribution by Steve Farr

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

    Contribution by Steve Farr

    10/12/12 Psyllids counts down. This is approximately 3-4 weeks after the regional Dimethoate application. Discussions going forward are to do a dormant Pyrethroid regional application in early November

    10/1/12 The Hardee County CHMA's met this morning in Wauchula to discuss the upcoming CHMA activities for the region. The next coordinated Asian Citrus Psyllid spray will begin on November 1st and continue through November 15th. The selected mode of action for this application will be a pyrethroid (Danitol, Mustang, ect…). Please follow all label instructions and pay close attention to PPE requirements, application rates, re-entry intervals, and post-harvest intervals.

    9/13/12 The latest report for the Roseto grove in Hardee County. This is approximately 5 weeks post the Agri-flex or Actara spray. Pressure is as high as we have seen since the scouting started. We are seeing tremendous better controls were the areas have had a regional application, meaning the entire area had a blanket application, either with an aerial or ULV by ground at night.

    This area is currently going with an O.P. material and David Terrel has his ULV machines in the area and is trying to go at night but has had to work around the wind the last 2 nights. If you are interested in coordinating this application, then call David at 781-0536

    9/4/12  The Hardee County CHMAs met this morning and it was decided that a coordinated spray will take place in the month of September.  The selected Mode of Action for this spray will be an Organophosphate (Lorsban, Dimethoate, Imidan).  Please follow all label instructions and pay close attention to PPE requirements, re-entry intervals, and post-harvest intervals. 

    8/20/12 ACP counts still down, post the Agri-flex spray. Growers are discussing to go with an organophosphate material for regional psyllid control in September

    Contribution by Steve Farr

    7/13/12 This Morning the Hardee County CHMA's met to discuss the next course of action for psyllid management. It is advised to continue with the summer oil sprays and to include a product that is approved for psyllid control. The product chosen for psyllid control during the summer oil sprays should not be a Pyrethroid, because a Pyrethroid will be used in the next coordinated spray.

    The next coordinated spray is scheduled for early September and the selected mode of action for that application will be a Pyrethroid. The early September date is subject to change and if a change of date is made the new date will be posted to the CHMA website. Please follow all label instruction for the material that is chosen.

    5/1/2012 A coordinated spray is begining on June 1, 2012 using Dimethoate.
    If a product other than Dimethoate is required then it is suggested to use an Organophosphate such as Malation or a similar product. Please remember to follow the label recommendations regarding Personal Protective Equipment, REI's and PHI's.

    4/11/12 A spray is suggested for April/early May.
    Using zeta-cypermethrin (Mustang) and a June spray to include dimethoate. Please remember to follow the label directions related to the REIs and PHIs.

    4/11/12 A spray is suggested for April/early May.
    Using zeta-cypermethrin (Mustang) and a June spray to include dimethoate. Please remember to follow the label directions related to the REIs and PHIs.

    2/2/12 Next target coordinated spray will be targeted for the March 1-15 period.
    The suggested spray is an organophosphate spray like Imidan (phosmet) or Malation 5 (malation) due to is short pre harvest interval (PHI) of 7 days as well as short restricted entry interval (REI). If phosmet is chosen, be sure to consult the label for buffering instructions when pH is greater than 7. Harvesting schedule and bloom period may require adjustments to the coordinated spray.

    1/4/12 A dormant spray is suggested for late Jan or early Feb.
    Using fenpropathrin (Danitol). Product has a PHI and REI of 24 hours.

    8/30/11 Next spray planned for October.
    During October, sprays of an organophosphate insecticide is suggested to be applied for psyllid suppression.  The exception to applying an OP insecticide will be where citrus leafminer is a problem and then spinetoram (Delegate WG) would be an alternative material.
