Request From: Steve Toth
Date Requested: Feb 16, 2008
Request: Note the following request for information on malathion use on tobacco. Please send any responses to the Southern Region IPM Center Information Requests Monitoring System by Friday, February 29, 2008 and I will forward them to Teung Chin. Steve Toth ----------------------------------- Dear Paul: In response to your attached 2/11/08 request, I am providing you with usage information for malathion on tobacco from Crop Profiles. No Pest Management Strategic Plans are available for tobacco. I am copying the IR-4 Program to see if they would consider generating residue data to support the use of malathion on tobacco. Since Cheminova and EPA are completing final labeling decisions for malathion, feedback is requested by the end of this week. I am copying the Southern Region IPM Center as well as FYI and invite them to provide any additional information. Kentucky - 483 pounds of malathion used in 2001. No pest identified. http://www.ipmcenters.org/CropProfiles/docs/KYtobacco.pdf North Carolina - no malathion use reported http://www.ipmcenters.org/CropProfiles/docs/nctobacco.pdf Tennessee 57 EC 0.825 - 1.66 lb ai/acre for aphids 57 EC 0.825 - 1.25 lb ai/acre for grasshoppers 57 EC 0.825 - 0.825 lb ai/acre for stinkbugs http://www.ipmcenters.org/CropProfiles/docs/tntobacco.pdf Virginia - no malathion use reported http://www.ipmcenters.org/CropProfiles/docs/vatobacco.pdf West Virginia Green June Bugs Malathion may be used to discourage feeding http://www.ipmcenters.org/CropProfiles/docs/wvtobacco.pdf Thanks in advance! Please do not hesitate to contact me if you have any questions or comments. Best regards, Teung ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Teung F.

EPA wants us to finalize our decsions this week, therefore, we need USDA to identify any critical uses that should be reconsidered. We appreciate your help with this task. Best regards, Paul Whatling Senior Manager of Regulatory Science Cheminova, Inc. 1600 Wilson Boulevard, Suite 700 Arlington, VA 22209 Office phone: 703-373-8883 (ext 1) Mobile phone: 202-271-0074 paul.whatling@cheminova.com ------------------------------------------------------------------------------------------------------------------------------------------------------ Proposed Cheminova Response to EPA: 1. Ships, Containers and surrounding areas Cheminova had previously made a decision not to support these uses. Our decision was based on the potential need for additional data requirements as well as risk assessment considerations. Cheminova is not aware that malathion is of critical importance for these uses; therefore, we do not intend to reconsider our decision. 2. Cereal processing plants, commercial and industrial uses for baffed flour and commercial storage/warehouses premises Cheminova is concerned that these are indoor uses that may trigger further inhalation toxicity and exposure data requirements. For these reasons, we have previously made a decision not to support these uses. Cheminova is not aware that malathion is of critical importance for these uses; therefore, we do not intend to reconsider our decision. 3. Forest trees Cheminova has prevously decided that it will not support the continued use of malathion on forest trees. Our decision is based on the need for further data requirements and to refine risk assessments. Cheminova is not aware of any critical use of malathion for forestry uses, therefore, we do not intend to reconsider our decision. Note that EPA has clarified that the current uses on pine seed orchards, poplar plantations, cottonwood plantations and Christmas tree plantations are ”terrestrial non-food uses”, rather than ”Forestry” uses. Cheminova will continue to support the use of malathion on the labeled terrestrial non-food uses (but not forestry uses). 3. Apples, almonds, gooseberry, peanuts, plum/prune, quince, post-harvest rice, soybean and sugar beets. Cheminova has made a decision to continue to support these uses. Therefore, we currently intend to generate the required data to support these uses. We would appreciate any help that USDA can provide to identy the use pattern needs by growers. 4. Citrus (post-harvest, dried pulp), cowpea, cranberry, dried peas (including pea vines), filberts, flax, lentils, safflower, sunflower, and tobacco. Cheminova previously decised that it will not generate the residue data needed to support the continued use of malathion on these crops. Cheminova is not aware that malathion is of critical importance for these uses; therefore, we do not intend to reconsider our decision. USDA should let us know if it intends to generate the required data. 5. Grape, post-harvest: this is for raisins; specifically "malathion use for the control of insects during the drying of grapes (raisins)" Cheminova had previously decided not to support a post-harvest use of malathion on grapes (raisins) because EPA wanted residue data on raisins and also on the formation of malaoxon on raisin drying trays. Cheminova is not aware that malathion is of critical importance for this use; therefore, we do not intend to reconsider our decision. USDA should let us know if it intends to generate the data to support this use.
