Abstract: The compound 4"-deoxy-4"-N-methylamino avermectin Bla/Blb has been discovered to have unexpected properties when used as an agricultural insecticide. Specifically, the compound is considerably more active against insects, particularly lepidoptera, than closely related compounds, and the compound exhibits significantly lower levels of mammalian toxicity and aquatic animal toxicity. Thus the compound presents a much wider margin of safety towards the human appliers of the compound and to other mammals that come in contact with treated areas as well as wider margins of safety to aquatic animals to which any spray drift or run-off containing the compound may be directed.
