No. 264-1007-66330) for control of insects in bulb vegetables, cucurbit vegetables, fruiting vegetables, root vegetables, tuberous and corm vegetables, pome fruits, tree nuts, field/pop/sweet corn, soybean, sorghum, and sunflower. (PREC Agenda, 8/3/06).
- On July 17, the FDACS registered Agriliance’s Delta Gold® (deltamethrin) insecticide (EPA Reg.
