AC 303,630, a member of a novel class of insecticides, is a broad spectrum insecticide/acaricide on many economic crops. It shows insecticidal activity by foliar application as well as by limited systemic uptake through the roots in a hydroponic system. AC 303,630 is highly active by ingestion, possesses contact activity and provides moderate residual activity on plants. It is effective at low application rates. Initial work has shown that the compound is equally effective against resistant and susceptible insects and mites. No phytotoxicity has been observed at field use rates. AC 303,630 is classified as moderately toxic to mammals based on acute toxicity studies and is nonmutagenic in the modified Ames and Chinese hamster ovary tests. AC 303,630 is under full scale global development for the control of insects and mites on cotton, vegetables and fruit. Field work has confirmed the effectiveness seen in laboratory and greenhouse studies.
