2009 Field Season Consultant Survey

The 2009 Field Season Consultant Survey was mailed out in January 2010. The results of that survey are now available for viewing online here or you can download the written report. The results of this survey will be compared to the 2007 Field Season Consultant Survey and compiled. A report of compariative findings will be posted when complete.

Please share your thoughts about the Guthion phase-out:

  • "Total phase-out is unnecessary. Limited use would allow growers to have an additional tool for codling moth at their disposal. Alternatives have not reduced the amount of pesticides applied to the environment or the total environmental impact due to increased applications of shorter residual products. Total labor and fuel costs will increase."
  • "I think that it is a valuable tool that should be retained for use in a restricted capacity but not totally eliminated."
  • "Since Guthion is already on a phase-out program we can’t really battle it. It would be nice if Guthion could be used once every 3-5 years. This should keep the new chemistries more viable in a chemistry rotation program. "
  • "1. There are situations where the use of Guthion still makes sense. But, 2. this should be on a case by case basis. 3. Grower input costs will and are going up--this is fact. 4. Replacement products need to have MRL's established before products are released for use. The complexity of trying to keep straight the residue issues for each grower, each variety and each export market is absolutely insane right now!!!"
  • "1 or 2 Applications of Guthion per season would be very helpful at 3 lb per acre rate."
  • "My only thought is that Guthion is still number one in the defense of codling moth, so I really feel it should be kept of a single application at 1st codling moth cover."
  • "I think it is a material that is needed because of cost and effectiveness in control. Many of the growers and consultants will have to be more vigilant in walking orchards and using IPM practices. (More cost for labor as well as chem.)"
  • "Guthion can be used safely in small or limited applications to clean up tough populations."
  • "I think that Guthion is an important part of the codling moth control rotation. I tend to use it when we are at a high percentage of egg hatch and it still works well even when coverage is not perfect. We will be losing a great tool that doesn't flare mites and aphids by killing their natural predators. This is the biggest problem I have with using some of the alternatives. Not only do the growers pay more for the products, they get to put on an additional miticide and aphicide that year. In general the cost of my programs have increased over $100.00 per acre due to these reasons."
  • "Would prefer to have the tool remain in the tool box, but excellent alternatives are available."
  • "Much of your research over the past years still shows Guthion as the best control. I am sad to see it go. It would be nice to have around as a backup. Timing is much more critical, growers must spray more often in hi pressure, some of the alternatives (Altacor) are not 100%."
  • "It would be nice to have Guthion to use in rotation for codling moth control. The new insecticides kill beneficials at twice the cost."
  • "New Guthion alternatives are too expensive. This will force more "smaller" growers out of business."
  • "The cheapest and most effective tool for control of codling moth is being taken away. It sucks but we're moving on."
  • "$$$$ - A cheap alternative will be lost."
  • "I think that there is no strong replacement/alternative for Guthion in high pressure codling moth orchards/areas."
  • "By phasing out Guthion (Penn CAP) we have increased the number of applications need to control (codling moth) - an application of pheromones equals the cost of 2 applications of Guthion. And I would not [use] any new product without the back of pheromone. I am in my 30th year of being a fieldman and I've seen way too many dumped on the backs of growers with no compensation for them (growers)."
  • "Phasing out Guthion, in my opinion, will not have any well defined impact on worker safety, environment, fruit marketing or consumer food safety. Phasing out Guthion reduces fruit growers' options. Reducing pest control options reduces pest control stability."
  • "I think the Guthion phase-out is something that is going to make codling moth control difficult for growers. I think the whole OP is a political agenda by environmentalists and the risk it perceives is blown out of proportion."
  • "The industry was in a no win scenario vs. the EPA on Guthion phase out. I don't believe Guthion was ever proven to injure or harm workers but here we are."
  • "Guthion is a broad spectrum insecticide that kills more than CM (aphid, mealybug etc). Early season use will be missed in good control of CM. Limiting the spectrum of control classes (types) are never good."
  • "I feel that Guthion is an important tool for the control of Codling Moth because of the quickness of its action to lessen the amount of stings. I do acknowledge that there are some handling issues with workers but I will miss its efficacy."
  • "As an Agricultural Chemical fieldman with 31 years experience I hate to see chemistries that work -disappear. New replacements cost the grower lots more and generally don't work as well. As a consultant, I'm forced to do more monitoring. I wish we still had Penncap M. I'm getting older and find myself studying more and more. With 31 years behind me I should be able to enjoy some short cuts you would think."
  • "The phase out of Guthion is costing my growers at least an additional $200.00 an acre per year. The alternatives are not working and causing additional pest problems."
  • "Codling Moth mating disruption is the corner stone of all effective control programs and OP's are not essential."
  • "Guthion phase out will be fine. But: 1.It will be expensive to growers. 2.Require more application for same days of coverage...not greener. 3.Will flare mites and allow the re-distribution of new pest threats that were once not an issue when Guthion was used. IE: Stink bug, weevils, etc."
  • "New chemistries are looked down upon by some of my growers because they, 1) cost more & 2) don't give the same level of control as OPs. Personally, I believe the positive effects out-weight the negative effects: 1) possibly better control of non-targeted pests by not killing their natural enemies, 2) improved safety for growers/ workers, 3) less harsh on the environment/ wildlife 4) improved consumer safety."
  • "It is time to move on and use alternative products."
  • "Should not be that hard; have been doing it for many years with very good results."
  • "It needed to be done."
  • "Don't need it. Gives me a headache when I go into Guthion Blocks. Was a very good thing for our Industry."
  • "Guthion had already begun its phase out over the years because of use and lack of effectiveness. The time is right for alternative and a more specific approach!"
  • "In the areas I work, Guthion has not worked very well or almost not at all for several years. So I have quit using it many years ago except in specific orchards and only very rarely. Guthion phase-out has not had any effect on my growers."
