Pesticide News Story: Disulfoton and Methamidophos Voluntarily Canceled
For Release: October 2, 2009
EPA has issued a final order approving the voluntary cancellations, requested by the registrants, of pesticide products containing disulfoton and methamidophos. The order, published in the Federal Register on September 23, 2009, cancels the last disulfoton and methamidophos products registered for use in the United States. These organophosphate insecticides are registered for use on a variety of food crop and non-food sites, including disulfoton use on residential ornamentals. EPA received no comments in response to a July 22, 2009 Notice announcing the Agency’s receipt of the requests for voluntary cancellation.
For all methamidophos products and most disulfoton products, the cancellations are effective December 31, 2009; two disulfoton products will be canceled effective December 31, 2010. Use of the disulfoton and methamidophos products canceled by this order may continue until existing stocks are exhausted, provided that use is consistent with approved product labeling. The registrants may sell and distribute existing stocks of most disulfoton products and all methamidophos products until December 31, 2010; two disulfoton products may be sold and distributed by the registrant until June 30, 2011.
