Request ID: 108
Request From: Steve Toth
Date Requested: Mar 09, 2005
Request: For those of you that have rice production in your states/territories, please note the following request for reaction to a proposed change in the rate of propanil on rice. EPA has only given until this Friday, March 11, on a response. You may want to expedite the response from your stakeholders via the telephone. Sorry for the short turnaround time. USDA's Office of Pest Management Policy personnel have expressed to EPA the need for 3-4 weeks of response time on such requests; but sometime that is not what happens. Thanks for your help. Steve Toth ------------------------------------ EPA is considering an amendment to the Propanil RED of 2003. It will likely result in a rate change on rice. The following change is being considered: A maximum single application rate of 4 lbs a.i. per acre. Seasonal maximum application rate of 8 lbs a.i. per acre. Background: The propanil RED was signed in September of 2003. Due to worker exposure concerns a biomonitoring study had been submitted by the registrant but was still under review at the time the RED was signed, and as a result it could not be included in the RED document. After reviewing the biomonitoring study the Agency still has concerns for worker exposures. Cathryn O'Connell, the EPA Chemical Review Manager, is currently in the process of putting together an Amendment document, which will explain the mitigation measures the Agency will establish based on the continued concern for worker exposure. The Agency is considering the above restriction for propanil use on rice. The Question: Please respond by Friday, March 11, 2005 concerning whether you feel the above measure is realistic, If not, please send Cathryn any comments or suggestions you may have to improve or change this restriction. Please respond directly to: Cathryn O'Connell Chemical Review Manager US EPA/OPP/SRRD/RBII Phone: 703.308.0136 Fax: 703.308.8041 Thank you for your time and help in responding to this request.

Response: I was able to get a hold of our rice weed scientist in the Everglades and he said that they are using Stam (propanil) at right around the 3 to 4 lb ai/A rate. So this amendment would not be a problem from Florida's standpoint. Mark Mossler UF/IFAS Pesticide Info. Office 352 392-4721

Response: Ford Baldwin is the former Weed Scientist for the Extension Service in Arkansas (now retired with his own consulting service). He knows more about weed control in rice than anyone else in the state and probably in the U.S. J.

University Little Rock, AR 72203 501-671-2234 Mobile: 501-944-0941 FAX: 501-671-2252 pspradley@uaex.edu --------------------- Ples: These can be lived with. The 8 lb./A total is certainly realistic. It would be nice if the first application allowed up to 5 lb. However if a 4 lb per application would avoid the 5000 acre per aircraft per week restriction we can certainly live with it. It is not often that I ever recommend above 4 lb in a single application anyway. The 5,000 acres per aircraft per week simply will not work. Ford L.
