Abstract

The invention belongs to the technical field of pesticides, and specifically relates to an avermectin composition and its preparation method and application. The invention provides an avermectin composition, the avermectin content is 1.8-10% calculated by weight percentage. The abamectin composition of the present invention is environmentally friendly and has low toxicity; it can effectively eliminate pests on rice, vegetables and fruit tree crops.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to an avermectin composition and a preparation method and application thereof. Background technique [0002] Abamectin is a widely used agricultural or veterinary fungicide, insecticide and acaricide. Also known as Amidin. Abamectin is a class of sixteen-membered macrolide compounds with bactericidal, insecticidal, acaricidal and nematicidal activities firstly developed by Satoshi Omura of Kitasato University in Japan and Merck Company of the United States. Produced by fermentation of the mold Streptomyces avermitilis. [0003] 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 larv...
