Abstract

The invention discloses a synergistic insecticidal composition containing avermectin and metaldehyde. The composition comprises effective components of avermectin and metaldehyde with a weight ratio capable of being 1: 0.1-80. Pharmacodynamic tests show that the composition has positive characteristics like strong complementarity, significant synergistic effect, expanded control spectrum, decreased application amount, prolonged appropriate application period, high safety to crops, reduced environmental pollution, and strong compatibility with the environment.

Description

technical field [0001] The present invention belongs to the field of agricultural plant protection, and in particular relates to an insecticidal composition with improved properties. It specifically relates to a synergistic insecticidal composition comprising abamectin and metaldehyde. Background technique [0002] The active ingredient Abamectin is a widely used agricultural or veterinary fungicide, insecticide and acaricide. Abamectin has stomach poisoning and contact killing effects on mites and insects, but cannot kill eggs. The mechanism of action is different from general insecticides in that it interferes with neurophysiological activities and stimulates the release of GABA, which inhibits nerve conduction in arthropods. Mite adults, nymphs and insect larvae will appear paralyzed symptoms after contact with abamectin, do not move, do not feed, and die after 2 to 4 days. Abamectin has a slow lethal effect because it does not cause rapid dehydration of insects. Alth...
