ABSTRACT

Cotton products have been under review at EPA under FQPA requirements and FIFRA reregistration of older products. To date, the focus has been on the 44 organophosphates (OP's), many are registered for use in cotton. Cotton OP products will be maintained for cotton with relatively minor modifications in usage restrictions. The 12 OP's to be maintained include Lorsban, Orthene, Curacron, Bidrin, Di-Syston, Thimet and Def/Folex (defoliant), malathion, methyl parathion, Cygon, Imidan and Supracide. Guthion and Monitor will be phased out over the next few years. Registrants are not supporting continued registration for Bolstar and Diazinon on cotton. In the next few months, EPA is expected to complete review of malathion, methyl parathion, and endosulfan and then the Cumulative Risk Assessment of the OP's as a group. In the meantime, EPA will continue with the FQPA/FIFRA review process on remaining products. Two groups of cotton products to be reviewed include the carbamates and the synthetic pyrethroids. There are nine new products for cotton that have been registered within the past 5 years and there are seven products in the advanced developmental stage. Also, the pipeline for future developmental products looks good at this time.
