Request ID: 171
Request From: Steve Toth
Date Requested: Mar 14, 2007
Request: State Contacts: As stated by Al Jennings (USDA's OPMP) below, EPA has developed two lists of crops for the Soil Fumigant Benefit Assessment. List 1 contains those crops they believe have significant fumigant use and anticipates focusing the assessment of the potential impacts of fumigant risk mitigation on these sites. List 2 contains those crops that EPA believes do not have significant agricultural use and they do not anticipate assessing the potential impacts of fumigant risk mitigation on these sites. The attached Word file contains memos on the subject from EPA and both List 1 and List 2. We are being asked to review these lists and let the agency know if the lists are appropriate. If your experts, growers and/or other stakeholders believe it important for EPA to assess the impacts of potential risk mitigation options on additional crops, please provide information describing the growing conditions and why an assessment should be conducted (see form on last page of handout). Please submit any responses from your respective states/territories to the Southern Region IPM Center's Information Requests Monitoring System by Friday, March 30, 2007. Thanks. Steve Toth -------------------------------------------------- Colleagues, I am forwarding a very substantial data request from EPA (see attached file) and asking that you please provide input. EPA would like to have your responses by April 1. Please let me know if you think that deadline is reasonable or not. Some of you and your cooperators will recognize this as very similar to an information request that was circulated through some grower-organizations a year or so ago. If there has been no change, it should be OK to dust off the older response and re-submit it. Basically BEAD is preparing to do soil fumigant benefit assessments for the crops identified in “List 1”. BEAD believes those crops may have significant benefits. “List 2” identifies crops that may use some soil fumigants but EPA believes the benefits may not be significant. They seek your opinions on the appropriate listing of crops and any other suggestions you may have on the benefit assessment plans. The specific data needs are listed on page 4 of the fumigant crop list memo. I have taken the liberty of expanding that list into the attached page in case a standardized format is useful to you. Please feel free to modify it in any way that makes sense to you. Thanks and best regards, Al Jennings Office of Pest Management Policy USDA

Response: Fumigants are critical for production of fruits in Georgia. Strawberries require fumigation with methyl bromide or methyl bromide alternatives on 100% of the acreage in Georgia, and without fumigation, we would simply not have sufficient production to overcome other costs of production. The 1,3-dichloropropene, chloropicrin and metam sodium products are among those utilized on strawberries as methyl bromide alternatives, but with methyl bromide exemptions, they have not been adopted to date. The 1,3-dichloropropene products are also utilized extensively in replant sites for peach. Likewise, methyl bromide or altenatives are utilized on replant sites for other fruit commodities, though the percentage of use varies.

Response: I will leave final word on cotton to Steve Koenning, but in my opinion there is no need to fight it on cotton. No concern with the other crops I work with (Corn, soybean, small grains). Alan York Department of Crop Science North Carolina State University

Response: None of my crops will be covered. Asimina Mila is the new Tobacco Pathology specialist and perhaps should be consulted. Steve Koenning Department of Plant Pathology North Carolina State University

Response: In Appendix A for tobacco there are checks in Dazomet, metam sodium and pottasium. I am not sure if these compounds are extensively used on tobacco. Chloropicrin and Telone are common but for the others I am not very certain. Asimina Mila Department of Plant Pathology North Carolina State University

Response: I didn't see turfgrasses on List 1 or List 2. Does this mean that they didn't know where to put it or that they're not worried about it? I'd say it should be in List 2. Lane P.

Response: Just to be sure I understand this: No other information is required since peanuts are already on the list for soil fumigant benefit assessment. Is that correct? Barbara Shew Department of Plant Pathology North Carolina State University
