    4/22/15 - The next round of CHMA applications are scheduled to begin next Monday, April 27, 2015 in the South Lake/West Orange CHMA and the Green Swamp CHMA.  Applications in the remainder of Lake and Orange, plus Seminole and Marion Counties are scheduled to begin one week later on Monday, May 3, 2015.

    The Mode of Action for this spray will be an Organophosphate.  There will be and option for aerial application.  If you want to utilize the helicopter please contact Grower Coordinator Rex Clonts, wrclonts@yahoo.com.

    It is important to have as much participation in these coordinated applications as possible to continue the downward trends we have seen in many of the blocks being scouted in the CHMA psyllid monitoring program. 

    4/14/14   Our next coordinated spray will start in the South Lake/West Orange CHMA (includes the old Green Swamp CHMA) on April 28th – May 5th.

    For the North Lake CHMA (old Central Lake/ North Orange & North Lake/Marion CHMAs) spray target date is from May 5th – May 12th.

    Please pass the word around for everyone to use an Organophosphate if possible. The helicopter will be operating in the Conserve area spraying Malathion @ 2pts which costs about $8.00/acre.

    So far this year my grove has noticeably lower psyllid population so thanks to everyone who participated in January. I hope you are seeing similar low populations.

    This application comes at a time when most of us are spraying anyway and everyone is feeling the pinch of costs. I just want to emphasize that timing during the 8 day windows is critical to overall psyllid control in the months to come.  Growers who have applied an insecticide earlier, please consider re-spraying during the CHMA window to get the best bang for the buck.

    While controlling psyllids doesn’t guarantee your grove will survive greening….. failure to control psyllids does guarantee it won’t.

    5/8/13 The recommendation for coordinated psyllid management sprays is to apply an Organophosphate at starting May 1st – 18th. The next coordinated spray should take place from June 15th – 29th using a foliar Neonicotinoid and an Abamectin material. Please follow all label directions for any material that is used.

    These spray recommendations come from the Volusia CHMA Coordinated Spray plan. The Volusia CHMA is one of the top preforming CHMA's in the state and the spray plans in use there have proven to be very effective against psyllids.

    The complete coordinated spray schedule for Volusia can be viewed on the Volusia CHMA webpage, under the planned pesticide link.

    9/5/12 A Central Florida CHMA meeting will be held tomorrow at the Lake County Ag Center in Tavares. The meeting will cover CHMA activity in the East Central Florida region. Presentation will be given by personal from the Florida Department of Agriculture and Consumer Services and The University of Florida. The meeting will begin at 9:30 am and will be held in the auditorium.

    The Lake County Ag Center is located at:
    1951 Woodlea Dr.
    Tavares, Fl. 32778

    2/1/12 - Discussion at the East Central Florida CHMA Roundtable today, February 1, 2011, reached a consensus that the following course of action is necessary in the various CHMAs in the region:

    • Application of a dormant spray of a pyrethroid insecticide as soon as possible to control overwintering psyllid populations in the citrus canopy is necessary.

    • Refer to Developing a CHMA Psyllid Management Plan at (http://www.crec.ifas.ufl.edu ) for commercial formulations of pyrethroid insecticides recommended for managing Asian citrus psyllid.

    • Always refer to pesticide labeling for all instructions, including pre-harvest interval, Restricted Entry Interval (REI), etc.

    The group at the CHMA meeting also determined that grower participation in the various CHMAs is vital in reaching the overall goal of reducing the populations of Asian citrus psyllids and thus slowing the potential of further HLB infection of commercial citrus plantings.

    1/5/11 – Important CHMA planning meeting Jan. 26 1:00-2:30PM.
    A planning meeting is scheduled for the North Lake / South Marion CHMA.  The meeting will be held on January 26, 2011 from 1:00 PM till 2:30 PM.  All growers with groves in this defined CHMA are encouraged to attend as plans are made for upcoming coordinated psyllid sprays for 2011. The exact location of this meeting will be announced soon, but please go ahead and reserve this time and date on your calendar.

    1/5/11 – Next coordinated psyllid spray planned for Feb 7 - Feb 21, 2011.

    The North Lake / South Marion CHMA will conduct its first coordinated psyllid spray of 2011 beginning February 7 through February 21.  Growers are encouraged to use a pyrethroid insecticide for this application as part of the ongoing effort to manage pesticide resistance development in local psyllid populations.  The two currently available pyrethroid insecticides available for use in Florida citrus are Danitol (fenpropathrin) and Mustang (zeta-cypermethrin).  Growers can use any application method they choose (aerial, low-volume, speed sprayer).  For additional information please contact Ryan Atwood (352) 343-4101.
