    4/5/16 As you can see from the attached plan, it has been simplified considerably. The fact is, the plan we've been sending out the last couple of years had become busy with too many sprays. Now that we have the bactericides the schedule for spraying has become ever increasingly complicated and overwhelming. I met with a small committee of growers active in the NE Desoto CHMA and it was our opinion to reduce the plan down to just four regional sprays. All four are at critical times for ACP control and the chemistry selected is the lowest cost available. The thinking is with all the noise in the system concerning the numerous spray options we have today, it would make sense to bring it all down to four sprays we can cooperate together on.

    This next REGIONAL spray is important because hopefully this will knock the psyllid population back at a time when the ACP is gaining momentum after the Spring flush. At least that's how it use to work before these past couple of Springs. In this next spray starting Monday April 11th were planning to use a Imidacloprid/Abamectin/Oil. This is a low cost spray and usually very potent. Remember, when we say regional, it doesn't mean just airplane. The idea is to use any spray method available but try to hit a 2 week window with your neighbors with the same chemistry or mode of action.

    Also, never hesitate to give us a call with any questions or if you would like to discuss this further. Please let us know if you have received this email and if you think this is the right direction to go with our CHMA.

    11/25/15 This REGIONAL spray is important because hopefully this will knock the psyllid population back far enough to avoid another spray until January. At least that's how it use to work before these past couple of Winters. By starting behind this last cool front cold we might have a better chance in keeping the numbers down.

    We're using Imidan an OP but any other OP will work. Also, were going with the airplane so don't hesitate to join up. Remember, when we say regional, it doesn't mean just airplane. The idea is to use any spray method available but try to hit a 2 week window with your neighbors with the same chemistry or mode of action.

    Also, never hesitate to give us a call with any questions or if you would like to discuss this further. Let us know how it's going for you.

    10/6/2015 As I said last year, this next REGIONAL spray historically is one of the most important of the year. If we can start behind an oncoming cold front and catch the ACP on a declining population we might have a good chance in keeping the numbers down for the Fall and maybe even into the Winter. We're using Baythroid a pyrethroid but any other pyrethroid will work. This is a variation from the original plan but it seems every other CHMA is going with a pyrethroid and we have put out two OP's recently so the change makes since. Also, were going with the airplane so don't hesitate to join up. Remember, when we say regional, it doesn't mean just airplane. The idea is to use any spray method available but try to hit a 2 week window with your neighbors with the same chemistry or mode of action.

    Right now we're looking at starting the mid October but it's going to depend on weather. Let's stay in touch and get it done together.

    8/21/15  We're starting a second August spray next week which is additional to the 2015 plan. Psyllid populations have been at record levels for weeks, however, it looks like we finally have them on the run, populations are coming down. We started our last spray earlier than we had planned and finished early, therefore, were coming right back with an airplane (Sunniland Aircraft) applied spray using Malathion. Hopefully, by hitting them again quickly we can hold the populations down so we can buy some time before our September spray.

    Naturally, were always wanting to hear your experiences so please stay in touch. If you need to ask any questions or discuss this further please feel free to call.

    7/24/15   We're starting the August spray next week which is classified as a "Regional Spray", meaning, let’s all spray together. Psyllid populations are a record levels, therefore, we moved this spray up a week similar to last year. Usually, this is the “hammer” spray that breaks the cycle of reproduction up enough that we can keep numbers down through the fall, we shall see.

    Naturally, were always wanting to hear your experiences so please stay in touch. If you need to ask any questions or discuss this further please feel free to call.

    7/1/15 We're starting the July spray next week which is classified as a major "Regional Spray". Historically growers have used an Organophosphate based insecticide with this spray. A July regional aerial Organophosphate application goes back to 2008 and has usually been very successful. There will be an airplane flying on most of this application, therefore, if you want to participate please contact Sunniland Aircraft or let us know.

    Naturally, were always wanting to hear your experiences so please stay in touch. If you need to ask any questions or discuss this further please feel free to call.

    6/4/15 This June spray isn't classified as a "Regional Spray" because historically growers do their own thing this time of year with some of the non-traditional chemistries. However, let's all plan on regrouping the first of July with an Organophosphate based insecticide.  A July regional aerial Organophosphate application goes back to 2008 and has usually been very successful.

    5/1/15   Attached please find the latest update to the NE Desoto CHMA. I must admit Orange-Co is taking a different path than the original schedule. Our psyllid populations are eerily high at this time, similar to last year. Therefore, were going with what we call "the hammer", a combination of a neonic, abramectin and oil, instead of an OP. This is usually a very successful spray and our hope is we can knock them back before summer. One of the advantages to using this mix is it's easier dealing with harvesting, plus were going with more gallons per acre to deal with canker.

    Never hesitate to contact us and let us know how your holding up and what your plans are.

    Thanks,

    3/20/15 Attached please find two spreadsheets. The first is the most recent Orange-Co scouting report and the second is the updated NE Desoto Spray Plan.

    The scouting report is interesting because last year, especially at this time, we were looking at some extremely high psyllid (ACP) counts. As you know, high ACP numbers continued for most of the year. However, the report this year reflects a different story. Starting in mid January the ACP have disappeared. We've had some flush all winter and early Spring but no ACP. Hopefully, this is a sign of how the ACP populations go this year.

    On the second attachment you'll find an update to the spray plan. It indicates the next regional spray will start around the first week in April, depending on the bloom finishing and where our ACP counts are. I know all of our sprays are important, but if we can stick together on this spray and keep the window small and all use a pyrethroid, maybe, just maybe we can keep the population beat down. We'll most likely be combining some ground spraying with some air spraying so if you need the airplane let Sunniland Aircraft know.

    Naturally, were always wanting to hear your experiences so please stay in touch. If you need to ask any questions or discuss this further please feel free to call.

    2/19/15   We’re planning on starting next week with the bloom spray using either Sivanto or Exirel. This will be a ground application at night. This shows as a regional spray, however, I'm sure not everyone's going to be spraying at this time but hopefully we can all hook up post bloom.

    2/18/15   The latest update for the NE Desoto CHMA.

    Amazingly, after working with a committee to come up with a proposed plan for 2015 we have eight sprays that fit with the majority of the acres within the NE Desoto CHMA, called Regional Sprays. Wow, eight out of 12 sprays. That means any grower within the CHMA can join in on any of the eight sprays and know the vast majority of the area is spraying the same type material or chemistry within the same time frame.

    Several things were discussed at the International HLB Conference held last week in Orlando regarding CHMA's. First, from Texas to Brazil to California and especially to Florida, if growers within a CHMA spray together, the data overwhelmingly shows psyllid (ACP) populations are reduced. Second, regarding using the same chemistry or mode of action against ACP, the data is starting show a reversal in the trend of more resistance to pesticides. This means, our attempt to rotate modes of action and all use the same chemistry with each spray is working to reduce resistance and more important than ever to continue.

    I promise I won't beat the drum about the two points made above about working together within CHMA's in each update, but last year was the toughest year yet we've had with psyllid populations. No doubt most was attributed to the constant leaf flushing we had all year long but we need to get better. Let's face it, were working against evolution. The ACP is trying even harder to survive our bombardment. The more you spray, the more we need to spray, we just have to be smarter and work together.

    Naturally, were always wanting to hear your experiences so please stay in touch. If you need to ask any questions or discuss this further please feel free to call.

    1/13/15 Attached please find the latest update to the NE Desoto CHMA Plan. Actually, I hesitate to call it the 2015 plan because I failed to get our committee together and build a program for 2015. The first spray highlighted, is our typical January dormant (?) pyrethroid that we've been spraying for years, recommended by all the entomologist. Before the next spray I hope to have the committee's recommendation to send out. The good news is for the last month our ACP numbers have been low.

    Orange-Co is going by ground, however, if you need a plane within the NE Desoto CHMA, just coordinate the spray with your pilot if you need our strip.

    Also, never hesitate to give us a call with any questions or if you would like to discuss this further. Let us know how it's going for you.

    11/12/14 This is the first time we've had to spray in November since we started spraying for ACP in 2006. Our ACP counts are finally trending down, however, our plan is to hammer them again on a declining population to keep them down. The hope is if we drop the numbers further we can wait until the next regional spray in January. We haven't used Dimethoate in years but we might have to supplement Baythroid in a few areas due to harvest intervals.

    Never hesitate to give us a call with any questions or if you would like to discuss this further. Let us know how it's going for you.

    10/2/14   I guess I spoke to soon in the last update about psyllid populations moderating. On the other hand, who could of predicted September would have so many wet/windy days. Our last spray took three and a half weeks, and normally we’re done in two. Scouting is showing pockets of high numbers but not quite as wide spread as over the summer.

    This next REGIONAL spray historically is one of the most important of the year. If we can start behind the oncoming cold front and catch the ACP on a declining population we might have a good chance in keeping the numbers down for the Fall and maybe even into the Winter. We’re using Imidan an Organophosphate, but any Organophosphate will work, also, were going with the airplane so don’t hesitate to join up. Remember, when we say regional, it doesn’t mean just airplane. The idea is to use any spray method available but try to hit a 2-3 week window with your neighbors with the same chemistry or mode of action.

    Right now we’re looking at starting the week of Oct 13th. Let’s getter done together.

    Also, never hesitate to give us a call with any questions or if you would like to discuss this further. Let us know how it’s going for you.

    8/19/14   Finally, our psyllid (ACP) numbers have moderated. We just finished the neonic/abamectin/oil ground spray and as usual, it turned the tide in most areas. I’m not convinced we’ll be able to hold off on the next scheduled spray (highlighted in the spray plan) until Sept 2nd but that’s our game plan unless ACP numbers start increasing. We’ll continue to target hot spots and let you know how it’s looking.

    One of my take home messages from the EXPO this year after talking to several growers and Entomologist was, this is a very tough year to control ACP. We’ve all experienced years that rust mite or other pest and diseases were impossible to control, well I think we’ve hit a year like that with ACP. All we can do is keep battling and hope the cycle changes.

    Also, never hesitate to give us a call with any questions or if you would like to discuss this further. Let us know how it’s going for you.

    7/24/14 Unfortunately, our psyllid numbers continue to be high. Over the last two weeks, since completing the Malathion/MicroMite spray, we have been aggressively treating "hot spot" areas. This approach is failing to keep up with the rising tide of psyllids, therefore, were starting earlier than planned a ground spray application using a neonic/agrimectin/oil combination, plus were starting the airplane using Danitol in front of the ground sprayers to quickly knock the populations back. Historically, the ground spray mix has been a hammer to bring populations down heading into the fall. With us being a couple of weeks earlier than normal this might cause the next few application to be sooner than scheduled too.

    Please contact me if you'd like to participate with the airplane. Also, never hesitate to give us a call with any questions or if you would like to discuss this further. Let us know how it's going for you.

    6/30/14  This next spray is a very important Regional Spray and I hope everyone will participate. We’ll be using an Organophosphate (OP), Malathion/Oil. There’s several OP’s available and all of them do a great job but it’s important all of us use the same chemistry with these big area wide sprays. The airplane will be flying using 10 GPA. Orange-Co will do some limited ground spraying around sensitive areas and power line blocks, plus, we’ll be adding some Micromite to help with the psyllid nymphs, leafminers, rust mites and weevils. However, just because we’re adding extra materials doesn’t mean you have to. To make the spray mix as low cost as possible the flying company can work out just spraying the OP if desired.

    Never hesitate to give us a call with any questions or if you would like to discuss this further. Let us know how it’s going for you.

    6/17/14    Please review the most recent NE Desoto CHMA update. As you can see were finishing up our first summer spray using Delegate this week. Psyllid numbers have been like a roller coaster since the bloom. The spraying were doing is knocking the populations down but by the time we’re covering the acreage again the adults and nymphs have returned.

    With that in mind, the next spray is a very important Regional Spray and I hope everyone will participate. We’ll be using and Organophosphate (OP), Malathion/Oil. There’s several OP’s available and all of them do a great job but it’s important all of us use the same chemistry with these big area wide sprays. The airplane will be flying using 10 GPA. Orange-Co will do some limited ground spraying around sensitive areas and power line blocks, plus, we’ll be adding some Micromite to help with the psyllid nymphs, leafminers, rust mites and weevils.

    4/29/14 We finally finished our Danitol post bloom spray. Unfortunately, storms and windy weather caused us to take longer than we wanted. Once we got started we experienced an explosion of psyllid numbers, especially nymphs, therefore, we added Grandevo to our mix for the 2nd half of the application. I guess it shouldn't of come as a surprise because since we have been aggressively scouting psyllids we have had ACP increases during the post bloom period six of the last seven years. The only year we didn't see an increase was last year and I think that was attributed to the extended bloom.

    We're starting right back this week with a ground applied Movento/Mustang application.

    Orange-Co is going mostly with ground equipment but if you need air spraying it can be arranged.

    Thanks,

    3/31/14 I’m sure some of you have a slightly different version based on whether you sprayed pre-bloom or during the bloom. The Closer application we put out did and excellent job of holding the psyllids down. Unfortunately, it looks like most growers have seen significant high numbers for a couple of weeks and ours are just starting to increase.

    I see some CHMA’s are cranking up this week with a Danitol spray. We’re scheduled to start on Ap 7th with a Danitol application due to having low psyllid numbers up until now and making sure the beekeepers are out of the grove. Our groves are clearly past the 90% open bloom stage at this writing.

    Orange-Co is going with mostly ground equipment but if you need air spraying it can be arranged.

    Thanks,
    Jerry
    863-559-2976

    3/14/14   As you can see from the attached Psyllid Scouting Report psyllid numbers remain very low. We just finished our night time spraying with Closer and at this point were in a holding pattern waiting for the bloom to finish before spraying again, unless we have a spike in psyllid numbers. Please be cautious when spraying at this time due to honey bees because were close to maximum bloom.

    The next scheduled regional spray is with a Pyrethroid (Danitol, Mustang) immediately after the bloom.  So the question is, when is the bloom going to be over ? I certainly don’t know but if I had to guess I’d say 3 weeks. Below I have copied Gene Albrigo’s bloom model for reference.

    Thanks,
    Jerry

    FLOWER BUD INDUCTION ADVISORY #7 for 2013-2014-2/19/14

    NOTICE FOR CITRUS EXTENSION AGENTS & SPECIALISTS AND GROWER NEWSLETTERS
    The following information has been developed as part of the Decision Information System for Citrus.
    L. Gene Albrigo, Horticulturist Emeritus
    Citrus Research & Education Center, Lake Alfred, FL
    This is a service to our citrus growers posted on the CREC website.  The internet Expert System on intensity and time of bloom can be accessed anytime: http://disc.ifas.ufl.edu/bloom/
    Current Status: Last advisory I discussed the lack of response of our model to the obvious current flower bud development and the stress induced bloom in January.   I recommend you bring up Avalon in the ‘Flowering Monitor System’ in order to get a truer picture of what is happening in your area.  Your area is likely to be a little ahead of Avalon. The prediction is for a full bloom of the current cohort by the end of February.  Remnants of the January bloom are overlapping into the beginning of this cohort.  A second regular cohort is predicted for the end of March to April 1st. If this scenario holds true, we should expect another extended bloom.  I am hoping that most of the available buds will flower in this cohort so that no buds will be available for a late March bloom.
    For those of you trying to determine the cut off for spraying harsher chemicals for psyllid control, it is going to be difficult to determine when 10 % of the flowers in the current cohort are open since some of the first (stress induced) blooms are still opening.  At best less than 10 % open flowers will have passed by this weekend.
    If there are very high flower counts in a 2 x 2 feet frame, you might try counting one square foot.  You can also take a ½ to ¾ inch diameter branch and count the total flowers and open ones on that branch.  It is relatively easy to keep track of where you are in the count on a branch if you are systematic as you move from the base through the branching.  A couple of these per tree side will be equivalent to a frame count.
    If you have any questions, please contact me (albrigo@ufl.edu).

    The next scheduled regional spray is with a Pyrethroid (Danitol, Mustang) immediately after the bloom.  So the question is, when is the bloom going to be over ? I certainly don’t know but if I had to guess I’d say 3 weeks. Below I have copied Gene Albrigo’s bloom model for reference.

    Thanks,
    Jerry

    2/11/14   Please see the latest revision of our spray plan. Because our psyllid numbers are remaining low our next spray won’t be starting until approx. Feb 27th. Because of the bloom implications we will be using Closer (Sulfoxaflor) sprayed at night by ground. Closer is one of the products IFAS has suggested for the flowering period, especially if the grower follows the bloom recommendations. As I said in the last update, there are several other options but we felt this fit us the best. We will be hitting our perimeters around the same time using an airplane, so if you need to coordinate with the pilot you should have time.

    Never hesitate to communicate your situation and if we can help in any way please let us know.

    Thanks,

    Jerry 863-559-2976        Buddy Strickland 863-381-2676

    2/7/14   It looks like most of our January Danitol applications are complete and fortunately our scouting reflects very low psyllid numbers at this time. Our original NE Desoto Spray Plan called for the next spray to be a regional application using Dibrome an OP. However, because of warm spells throughout the winter and stress on HLB trees, we have quite a bit of bloom emerging. Unfortunately, it would be difficult to complete a regional application with an OP over the next month. It’s certainly possible for individual growers depending on their bloom stage to act quickly, especially if their seeing psyllids. I have attached a revised spray plan that eliminates the OP in February and moves right into one of the bloom labeled products. Orange-Co plans to use the revised plan and mostly spray at night. If the bloom becomes extended and psyllids start to increase then we’ll use another bloom approved material per the revised plan. It appears the next regional spray that can be carried out uniformly will be the post bloom Danitol.

    It’s easy to sit behind a desk and write down a plan that looks great but when it comes to farming, rarely do we get to make the schedule. I think these last couple of winters are good examples. The revised plan that’s attached is one possibility, however, there’s many different options. I think it’s up to each of us to evaluate our individual situation over the next couple of months and do the best we can and then meet up again at post bloom.

    This has been a difficult discussion to have via email so please if you have any questions don’t hesitate to call and discuss in more detail.

    Thanks,

    1/13/14 Psyllid numbers are on the rise in a few places so it appears our application starting this week is well timed (see spray plan).

    1/3/14 Based upon a committee meeting of some NE Desoto CHMA members, a spray program was developed for 2014. The idea was to simplify the program to six regional sprays with low cost psyllid control products with the hope of getting 100% participation. Please find a detailed program that outlines the CHMA sprays under the planned pesticide applications link. As you can see, the next major regional spray is going to start Jan 13th, depending on weather. Hopefully, with all of these regional sprays the airplane will be available to supplement ground spraying. It is recommended we try to coordinate these sprays within a two week window and use the same chemistry to avoid resistance issues.

    Please call us if you need help coordinating applications and never hesitate to tell us your plans and results.

    11/22/13 Psyllid numbers have be low since our last spray. At this time were not planning a overall grove application but we are planning a perimeter spray using Danitol and we will continue to spray isolated finds. The perimeter spray will start next week depending on weather. We are using an airplane for a portion of the application so please feel free to coordinate any of your applications with Sunniland Aircraft.

    Thanks,

    Jerry 863-559-2976 Buddy Strickland 863-381-2676

    10/10/13 Based upon low psyllid numbers and waiting on the weather to change we delayed the start of the next spray application until next week (see attached plan). The airplane will be flying starting Monday, therefore, if you haven't scheduled your spray you have plenty of time.

    Jerry Newlin

    9/27/13 Psyllid numbers continue to be low. Fortunately, our August and September sprays did a good job of getting the numbers into acceptable ranges, despite all the rain. I'm not sure about your groves but this wet summer has brought on one of the largest most uniform Fall flushes I've ever seen. Of course, when you have flush you have psyllids but I think we knocked them back so hard pre-flush we hopefully can pound them down with this next major area wide aerial spray. The next spray is with an Organophosphate, were using Imidan, but any Organophosphate will work. Right now we have plans to start the plane moving the week of the 7th but naturally, that could be delayed some depending on weather and psyllid pressure.

    Please let us know if you want to participate. Historically, this has been one of our most important sprays for keeping the numbers down through the winter. Also, give us your comments and call anytime.

    Also, I'll be scheduling a meeting of our CHMA to discuss next year's plan.


    Thanks,
    Jerry 863-559-2976     Buddy Strickland 863-381-2676

    9/6/13 The good news is we seem to have weathered the bump in psyllid numbers we experienced mid-summer but we can't let up now. We're starting a Delegate spray Monday the 9th that should take about two weeks depending on weather. We're using ground rigs at 3 mph and 50 gpa. The next spray will be with an airplane using an Organophosphate sometime in October.

    Please give us your comments and call anytime.

    7/31/13 We just completed the Malathion aerial application and a Grandevo perimeter spray. Unfortunately, our psyllid numbers have increased some, especially on our eastside where we started the last spray. Our next spray starts Monday Aug 5th. We're using a Neonic/abamectin combination that's worked great for us over the last several years. This is our second summer Greasy Spot spray; therefore, we'll be going with ground application which will take 3-4 weeks. In the middle of Aug we'll hit the perimeters again or any hot spots.

    Please give us your comments and call anytime.

    Thanks,
    Jerry 863-559-2976     Buddy Strickland 863-381-2676

    6/24/13 We just completed the Delegate ground application and our psyllid numbers are still low. Today we started with the airplane spraying our perimeters; hopefully it will only take a couple of days. The next big airplane regional spray is scheduled at Orange-Co for July 8th but other area growers are stating from the 1st on. If you want to participate with the airplane I've included his contact information below. Remember, this spray is scheduled for an Organophosphate. At Orange-Co were using Malathion for REI issues but Dimethoate, Lorsban/Chlorpyrifos, Imidan all the same modes of action.

    6/6/13 In the last update the psyllid numbers were down and we intended to keep pounding them. It looks like our efforts have worked. These are some of the lowest numbers we've ever seen for this time of year. Maybe it's the weather or screwed up bloom but I want to think it's our intensified spraying, at least it makes us feel better saying that. Per the spray chart were not stopping now. We started another complete spray this week dodging rain and storms but we'll be hard at it when we can.

    Please give us your comments and call anytime.

    See you in Bonita,
    Thanks,

    5/3/2012 - A new coordinated spray schedule has been posted to the Northeast Desoto CHMA website, under the link Planned Pesticide Applications. The spray schedule from 2010 – 2011 has been archived under a new link, Past pesticide applications.

    The next scheduled coordinated spray will begin on May 4, 2012. Please see the spray schedule for material recommendations. Also, please follow the label for any pesticide that will be applied, especially in regards to Personal Protective Equipment, PHI's, and REI's.

    In April we were seeing higher psyllid numbers, so were all the other CHMA's. The good news is we continue to have some of the lowest numbers statewide. The important take home message is the regional sprays are working. The more growers work together the better the results. Call with any comments or if you want to work with the airplane.

     

    11/14/11 - First dormant spray could be scheduled for mid November with an organophosphates (OP) or pyrethroids.
    OPs have a long pre harvest interval (PHI) ranges from 7 to 21 days (Lorsban 21 days; Dimethoate 15 to 45 days; Malathion 7 days; Imidan 7 days) and may not be a good option as the PHI may impact harvesting schedules. Pyrethoids have a much shorter PHI of 12 hrs (Mustang) to 24 hrs for Danitol and may work around harvesting schedule much better than the OP. When using any pesticide, be sure to read the label and follow the directions. Labels between products with the same active ingredient may vary in regards to REI, PHI and/or amount to apply.

    Second dormant spray (Jan/Feb) is suggested to use a pyrethoid due to short PHI and they (pyrethoids) tend to work good in cool/cold situations and have a short PHI that would be very flexiable around harvesting operations.


    10/12/11- Next psyllid spray scheduled for Oct 20
    At Orange-co we were all ready to go with the next regional spray on Monday the 17th but because of the approaching cold front due in next Wednesday we have rescheduled to spray behind the weather change. Historically, if you can spray most pest in the Fall once cool weather has started, the success rate for longer control is usually good.  Our new target starting date will be Thursday, October the 20th, depending on weather.

    The plan calls for an Organophosphate this cycle and the airplane will be flying off of Orange-co’s strip if you would like to participate. Let us know.

    Also,  in the last update I mentioned the FDACS/USDA  psyllid scouting. I’m really impressed with the program so far. Check out the CHMA scouting reports and look what CHMA has the fewest psyllid numbers Obviously, we won’t always have these kinds of results but it makes you feel better about all the effort and dollars were spending.

    Never hesitate to give us a call or e-mail us about your plans and thoughts. Hopefully, in the next month our committee (anybody welcome) will get together to map out a plan for 2012.

    Thanks,
    Jerry

    3/4/11 - Next psyllid spray scheduled for April 11.
    Below please find the proposed spray plan for Orange-co for 2011. Naturally, this can change based on scouting and other factors. I would like to hear your opinion or see what your plans are. As you can see, I've included our Leaf Miner strategy too. Also, attached please find our most recent psyllid scouting report. If you have any questions give one of us a call.

    9/29/10 - Next coordinated application being planned for late Oct / early Nov.
    Dear NE Desoto County CHMA members, Below please find highlighted the next scheduled start date for a regional spray. The plan was to use a Organophosphate (OP) sometime late Oct or early Nov. Some us will be using an airplane at 10 gpa, however, the important part is to try and spray within a 2-3 week window and to use an OP for resistance considerations (at Orange-co we'll be adding 3oz per acre of Agri-mek/Oil for leafminer and rust mites).

    6/23/10 -NE Desoto Growers Group (NE Desoto CHMA) Program for the next 12 Months
    After our last meeting a few of us came up with the below listed psyllid control plan for the next 12 months. Also, Dr. Michael Rogers with IFAS, reviewed and signed off on the program relative to effective psyllid control and chemical resistance management. I have also included for informational purposes Orange-co's leafminer control plan because of canker (Agri-mek and Intrepid). We realize this is an aggressive program but the fact is, some of us will be spraying in-between these scheduled sprays due to scouting information. I think all of us can agree that the application method can vary but the timing of the sprays need to be as close as possible. Also, not everyone's going to want to do all seven sprays together but the more we do the more successful were going to be. If you're not going to do all the sprays, at least try to coordinate the ones your planning. Orange-co is willing to be the clearing house for the coordination and we will send out regular psyllid scouting results. Give us a call and let us know what you think and what your plans are……….thanks, Jerry
