The article presents the results of testing the oxadiazine insecticide Avaunt with the active substance indoxacarb against the cotton bollworm on cotton and the mulberry moth on mulberries. In all experiments, high efficiency against caterpillars of all ages was obtained, which greatly distinguishes it from other preparations - larvicides. Depending on the objects, the consumption rates of the preparation can be in the range from 0.3 to 0.45 l / ha. The preparation is practically non-toxic for entomophages - trichogramma, bracon and lacewing, which is especially valuable in integrated plant protection programs.
