Request From: Steve Toth
Date Requested: Jun 29, 2005
Request: Note the following request for information on chloroneb seed treatment uses on cotton and soybeans. Please circulate this request to the experts in your respective states/territories and submit any responses to the Southern Region IPM Center Information Request Monitoring System by July 13, 2005. Have your folks answer for your state/territory and I'll collate the answers for the Southern Region. Thanks. Steve Toth ------------------------------ Your feedback is requested specifically for the use of chloroneb as a seed treatment for cotton and soybeans. We'd like the information by July 13, if at all possible. USDA is meeting with the registrant and EPA on July 14. But if a response by July 13 is not possible, we would like feedback by July 21 (the public comment period closes on July 25). Thank you for your responses to our March 2005 questionnaire. The registrant is seeking to defend the cotton seed, soybean seed and golf course (no info needed for golf course) uses. COTTON We believe most of the chloroneb used for treating cottonseed is done in California and the Southwest where stripper cotton is grown; that chloroneb is not being used on picker cotton which is grown in Texas; that picker cotton gin by-products are fed to cattle but not stripper cotton gin by-products. Your feedback will help refine EPA's risk assessment which assumes 100% of cotton seed is treated with chloroneb and 20% of gin-trash is being fed to cattle (resulting in possible residues in meat and milk). A Texas A&M study concluded that gin trash is not being fed to dairy cattle. The National Cotton Council would like to see chloroneb retained as a seed treatment. (1) What percent of cotton seed in your IPM region (Southern Region, Western Region) is treated with chloroneb? Also, please identify the region : Southern Region [TX, OK, AR, LA, AL, MS, TN, KY, VA, NC, SC, GA, FL) or Western Region [AK, AZ, CA, ID, NV, NM]. (2a) What percentage of the chloroneb-treated cotton seed is stripper cotton? (2b) Are the stripper cotton gin by-products from seed treated with chloroneb being fed to cattle? (3a) What percentage of the chloroneb treated cotton seed is picker cotton? (3b) Are the picker cotton gin by-products from seed treated with chloroneb being fed to cattle? SOYBEANS (1) What percentage of soybean seeds in your IPM region are treated with chloroneb? Also, please identify the region: Northeast Region, NorthCentral Region, Southern Region, Western Region. http://www.ipmcenters.org/about.cfm (1a) What percentage of soybean by-products are fed to livestock? (1b) What percentage of soybeans by-products from soybean seeds treated with chloroneb are fed to livestock? -------------------------------------------------------------------------------------------------------- Chloroneb Risk Assessment; Related Document, and Input on Risk Management; Notice of Availability http://a257.g.akamaitech.net/7/257/2422/01jan20051800/edocket.access.gpo.gov/2005/05-10576.htm http://docket.epa.gov/edkpub/do/EDKStaffCollectionDetailView?objectId=0b0007d48047229e

Response: After distributing the request for information to the appropriate specialists/researchers, I received the following responses: Dr. Craig Rothrock, Professor - Dept. of Plant Pathology, Univ. of ArkansasSeed treatments depend on the companies treating the seed. It has nothing to do with picker vs. stripper cotton. Callifornia has a lot of seed treated with Chloroneb because of the presence of Wilbur-Ellis. Syngenta nor Gustafson use the product as standard seed treatment on cotton, so in the midsouth it is in some custom seed treatments which is increasing. I would think it is on less that 5% of the seed. 0% stripper. Dr. Tom Troxel, Extension Beef Cattle Specialist, Coop. Ext. Ser., Univ. of Arkansas, responded that cotton seed by-products (i.e., gin trash) is occasionally used for cattle feed in Arkansas. Its primary use is as a "filler" to bulk up the rations because it is not very nutritious.

Response: For Oklahoma we do not have a Plant Pathologist working on cotton and soybeans so the best answer I have would be to contact the seed companies or Gustafason to find out if chloroneb is used in treating cotton seed for Oklahoma. Cotton seed for Oklahoma comes already treated in the bag by the seed companies custom seed treating done that I am aware of for cotton. I really don't think they would use different seed treatments for picker cotton versuas stripper cotton for Oklahoma. On the soybeans we do not have the personal to answer that question espcially the byproducts treated with chloroneb.
