Request From: Steve Toth
Date Requested: Apr 08, 2005
Request: Note the following request for information regarding a list of uses of malathion to be voluntarily cancelled by EPA. Please forward this list (attached) to the experts/stakeholders in your state/territory and solicit their responses. If there are malathion uses on this list that should be retained, please respond to me via the Information Request System by the APRIL 29, 2005 deadline. Thanks. Steve Toth ----------------------------------------------------- Attached is a list of uses that the registrant has agreed with EPA to be voluntarily canceled. EPA will issue a 6F Federal Register notice in the near future. USDA is sending this in advance of the 6F cancellation notice. If you believed any of these uses should be retained, please notify me by April 29. Please explain why the use should be retained and provide your contact information in case we need additional details. Because the registrant has decided not to generate the data needed to support these uses, USDA will need to explore the feasibility of other options to support the uses, a somewhat lengthy process. Also, the availability of the revised risk assessment for malathion for public comment has been delayed until mid-May or so. We will keep you apprised. (See attached file: Malathion-Uses-to-be-deleted-March05.doc) Please do not hesitate to contact me if you have any questions or comments. Teung F.

Response: Malathion use in tobacco is low. There are generally more effective alternatives in all cases. Thus, I would not argue against this cancellation.

Response: I can provide considerably more details but, in brief, none of the crop cancellations will adversely impact Texas agriculture and none of the structural/storage uses are economically or biologically important. However, in the animal listings, the use of malathion for ectoparasites in sheep and goats IS extremely important. I am working with Teung Chen with USDA/APHIS on some detailed assessments and impacts (he had asked for information earlier). Please let me know if you need more information. Dudley T.

Response: We completed an assessment of Malathion uses and needs in Texas. In brief, none of the proposed cancellations in the crops grown here (apples and peanuts), animal uses, and use in storage/ commercial facilities or structural uses would be adversely impacted EXCEPT FOR lice control in sheep and goats. Please forward these notes on to the Agency for us. (Some acknowledgment would be appreciated, if possible - when received and filed with EPA.) These small ruminants are the main (and on some ranches the ONLY) domestic livestock species raised in the Edwards Plateau region (an uplifted limestone region, characterized by shallow soils, arid conditions/ sparse rainfall, and predators). In this industry, "lice and ticks" on sheep and goats have an impact like uncontrolled weeds in cropland, regarding their impact and major economic losses - in fiber (wool and mohair) production, raising of lambs and kids for meat, and the ultimate survival of the ewes and does. The attached Assessment includes a list of some alternative products but these are NOT labeled in the U.S. although some of them have been evaluated and are very effective. Research (state and federal), Extension, and industry people in Texas would be pleased to talk with the present registrant or with Agency people, particularly if there could be a fast track or special consideration for registering some alternative for Sheep and Goats. The loss of malathion really would create a problem in an economically stressed industry. Dudley Smith Texas A&M University
