    2/27/15 Just a reminder as we had discussed in the last notice for an area wide spray. We will be planning an area wide spray application immediately Post Bloom. Please help me remind all bee keepers they will have a very short amount of time to get the bees out. Right now we are estimating two or three weeks.

    MOA will be a Pyrethroid and I think most will use Danitol. As usual Jerry Wise will be available. Make your plans now.

    Let me know if you see someone missing from the distribution list and I will add them to it.

    11/21/14 The next coordinated spray will take place the first week in December. Mode of action will be an Organophosphate or Neonic due to the fact we have sprayed Pyrethroids the last two or three sprays. Some of us may be harvesting but selecting the correct product and scheduling the application will not interfere with harvesting. Make sure to contact Jerry Wise if you intend to use him so he can schedule his planes.

    The next scheduled coordinated spray will take place the first week in January and looks like a Pyrethroid will be the mode of action.

    12/10/13 The Central Highlands 17/27 CHMA met today to formulate a strategy for area wide Asian Citrus Psyllid management. A year long, comprehensive, spray plan was developed to maximize the efforts of the CHMA. The spray plan can be found by clicking on the link titled "planned pesticide application". The spray plan only details the date that the spray will occur and what mode of action will be utilized. The decision about the method of application and any other product that is added to the tank is left up to the individual grower. The CHMA Program is only focusing on the timing of the spray and what the insecticide mode of action is.

    For most of the psyllids sprays planned there will be an airplane available to aid in the application. If you would like more information about utilizing the airplane please contact John Gose or Laurie Hurner.

    10/30/12 A coordinated spray is planned for the Central Highlands 17/27 CHMA. The coordinated spray will take place during the month of November. The selected Mode of action for this spray will be an Organophosphate. If the use of an Organophosphate is not possible due to harvesting activities, a Neonicotinoid should be used as a substitute. The coordinated spray plan for this CHMA can be accessed by clicking on the link titled "Planned Pesticide Applications".

    4/3/12 Most growers are in the process of their post bloom spray. Some are using insecticides with minimal PHI restrictions and some are not adding any insecticides for ACP due to low populations. The main focus with this application is delivery of nutrients which require a slower application speed.

    We had originally talked about a post bloom application however with harvesting activities in our area an Organophosphate application with extended PHI's would be very difficult if not impossible for all acreage to be sprayed in a two week period. Dr. Rogers has said many times that the two week window is critical for success in these coordinated sprays as well as covering the entire acreage.

    ACP populations in our area are increasing slightly but mainly in groves that have not been participating in coordinated spray efforts. The good news is with the spring flush hardening off the insects will not have any new flush to lay eggs on to start the next generation. The only exception to this will be young trees but if growers have applied Neonicotinoid soil drenches with young trees will not support nymphal stages.

    The next scheduled coordinated spray for our area will be early to mid-May 2012. I will be in contact with growers as we get closer as to specific dates. We will monitor ACP populations closely and we need to communicate with each other on what we are seeing. Looks like mode of action will be an Organophosphate.

    One of the main goals of coordinating these sprays is to possibly reduce the number of insecticide applications. I think we have been successful in that our numbers have remained low during the spring flush. I want to encourage all growers in the Central Highlands 17/27 CHMA to take part in this next coordinated spray. The next spray will be critical to suppress ACP populations prior to the summer flush.

    Post Bloom Spray: The next coordinated spray will probably occur in early May!

    12/19/11 The second scheduled dormant spray for our area will be during the time frame of January 3, 2012 through January 17, 2012.
    Dr. Rogers has recommended a Pyrethroid for this application. The options Dr. Rogers has listed on the CHMA site are Danitol or Mustang. Some growers are facing a growing problem with spider mites so Danitol will be the material for this application. We do have Dr. Roger's approval to go back to back with Pyrethroids during the dormant period because new ACP populations are not the target. Plan to make arrangements for this application. Dr. Rogers said that it is very important to have these sprays out in a two week window or we will fail in our effort to control Psyllids in a wide area. The full spray schedule for our CHMA is posted on the CHMA webpage so we can all plan accordingly.

    Our ACP inspection numbers are still low as are most for our CHMA. We are pulling the trigger earlier than normal with this spray due to two reasons, first the mild winter we are experiencing and the fact that hedged groves have already begun to flush will promote early ACP reproduction, second as mentioned above growers are beginning to have problems with spider mites.

    Our CHMA neighbors to our north and south have planned on this application and the expanded area wide effect should be noticeable for all of us. The next spray is scheduled for post bloom. Some discussion about another dormant spray at pre-bloom is going on so I will keep you posted.

    11/8/11 – The first scheduled dormant spray for our area will be during the time frame of November 9, 2011 through November 22, 2011.
    Dr. Rogers has recommended a Pyrethroid for this application. The options Dr. Rogers has listed on the CHMA site are Danitol or Mustang. Mustang will be the preferred choice as most growers would like to use Danitol in the next dormant spray. We do have Dr. Roger's approval to go back to back with Pyrethroids during the dormant period because new ACP populations are not the target. Plan to make arrangements for this application. Dr. Rogers said that it is very important to have these sprays out in a two week window or we will fail in our effort to control Psyllids in a wide area. The full spray schedule for our CHMAs is posted on the CHMA webpage so we can all plan accordingly.

    Our ACP inspection numbers are still low as are most for our CHMAs. We need to encourage our neighbors who may not be participating to consider making these two dormant sprays so we will have very low numbers going into the spring flush period.

    The next spray is scheduled for the January or February 2012. We will try to combine our spray with our CHMA neighbors to the south and possibly the north. I will keep you posted.

      11/8/11 – Central Highlands 17/27 CHMA Plan – 2011/2012


    10/18/11 – Next CHMA planning meeting scheduled for 9:30AM Nov. 1 at Lykes
    Growers and Caretakers in the Central Highlands 17/27 CHMA,

    At our first CHMA meeting last year we decided to hold a second meeting once we got through the first year of coordinated sprays to discuss our findings.  The second meeting will be held on Tuesday November 1, 2011 at 9:30am in the Lykes office.  This is the same location of last years’ meeting and the address is below in my contact information.  Dr. Rogers will be on hand to answer any questions we may have.  Please make plans to attend this very important meeting as we will be making plans for the coming year. 

    The next scheduled spray will be in the mid November period.

    Thanks,
    John

    3/14/11 – Next coordinated spray scheduled for Mar 28-Apr 11
    The scheduled Post Bloom spray for our area will be during the time frame of March 28, 2011 through April 11, 2011. Dr. Rogers has recommended an Organophosphate for this application. The options listed on the CHMA site are Lorsban, Dimethoate, Malathion and Imidan. Plan to make arrangements for this application. Dr. Rogers said that it is very important to have these sprays out in a two week window or we will fail in our effort to control Psyllids in a wide area.

    We don't have a timeframe for the next spray as growers have agreed that oil sprays will be applied during the summer. Please consider other modes of action besides an Organophosphate or Pyrethroid. You can visit the link below for information on other options.

    1/10/11 – Next coordinated spray scheduled for
    Jan 31-Feb 14.

    The second scheduled spray for our area will be during the time frame of January 31, 2011 through February 14, 2011.  Dr. Rogers has recommended a Pyrethroid for this application.  The options Dr. Rogers has listed on the CHMA site are Danitol or Mustang.  Plan to make arrangements for this application.  Dr. Rogers said that it is very important to have these sprays out in a two week window or we will fail in our effort to control Psyllids in a wide area.  The full spray schedule for our CHMA is posted on the CHMA webpage so we can all plan accordingly.

    I wanted to share some results of our last ACP inspection with our CHMA group.  Our inspections consist of fifty samples per area checked.  We use the Tap method and count the number on the clipboard.  We then apply a percentage based on the number of stops and the number of ACP.   On the southern end of the grove we had 100% participation by growers and our numbers are showing a 2% rate.  On the north end of the grove we did not have 100% participation and the rate is running 18% to 24%.  As we moved south to north with the inspection the number gradually got higher.  This shows how effective the CHMA concept works.

    The next spray is scheduled for the post bloom spray period probably in the April timeframe.
