US EPA mulls diflubenzuron exemption
The US EPA has received a specific exemption request from the Wyoming Department of Agriculture to use the insecticide, diflubenzuron, to treat up to 26,000 acres (10,522 ha) of alfalfa to control grasshoppers and Mormon crickets. The applicant claims that registered alternatives would not provide adequate control to avert significant economic losses. The proposed use is supported by the minor-use IR-4 Project. A similar request has been submitted for five or more years without a tolerance petition being submitted, the EPA notes. The request is open to public comment until May 15th.
