Fulfull™ is a new insecticide from Ciba research that came into our development effort several years ago. It is a representative of a novel new class of chemistry referred to as a pyridine azomethine derivative. It came into our screening program as CGA-215944 with the common name - pymetrozine - now approved. We plan to use the trademark Fulfill in cotton for aphid control. A 50% wettable powder formulation is currently in development while a water dispersible granule is under consideration.
