US EPA extends scope of pheromone exemption
The US EPA has extended the scope of the tolerance exemption for the insect pheromone, lavandulyl senecioate, following a request from US biopesticide company Suterra (Bend, Oregon). The pheromone is used as a mating disruptant for vine mealybugs (Planococcus ficus). The original tolerance exemption covered use in retrievably sized polymeric matrix dispensers but Suterra applied to use an aqueous suspension of micro bead/dispensers through normal spray equipment. The original exemption did not allow for repeated dietary exposure from sprayable formulations.
