Insecticidal composition containing avermectin with synergistic effect

Abstract

The invention relates to an insecticide compound of avermectin and nitenpyram, which is characterized in that the effect components of the invention are avermectin and nitenpyram, and the mass ratio of avermectin and nitenpyram is between 0.1:50 and 5:1. The invention has the advantages that obvious synergy effect and persistent effect can be achieved after remixing, and plural functions of broadspectrum, high efficiency, low toxicity, low pollution and low residual against aphides, whiteflies, spiny white flies, tobacco whiteflies and the like which are common on fruit trees and cotton can be achieved. Besides, the consumption and application times of pesticide are substantially decreased, costs are reduced and the drug resistance of pests is retarded.

Description

technical field

[0001] The invention belongs to the technical field of compound pesticides, and in particular relates to a rich compound pesticide of abamectin and nitenpyram. Background technique

[0002] Abamectin: It is a macrolide disaccharide compound. It is a natural product isolated from soil microorganisms. It has contact and stomach poisoning effects on insects and mites, and has weak fumigation effect, without systemic effect. However, it has a strong penetrating effect on the leaves, can kill pests under the skin, and has a long residual effect. It does not kill eggs. Its mechanism of action is different from that of general insecticides in that it interferes with neurophysiological activities, stimulates the release of r-aminobutyric acid, and r-aminobutyric acid has an inhibitory effect on the nerve conduction of arthropods, and acarids, nymphs and insects are related to The larvae will appear paralyzed after being in contact with the drug, will not move or e...
