Abstract

The invention discloses a pesticidal composition containing spiromesifen and nereistoxin, which contains an active component A and an active component B, wherein the active component A is selected from spiromesifen; the active component B is selected from any one of thiocyclam, bisultap and monosultap; and the weight ratio of the active component A to the active component B is 1:80-60:1. The composition has a synergistic action on multiple pests jeopardizing agricultural production, reduces the pesticide consumption, lowers the residue level of the pesticide on crops, relieves the environmental pollution, is safe for both human and livestock and has favorable environmental compatibility, and the pests can not easily generate drug resistance.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to the application of an insecticidal composition containing spiromethicone and necrotoxin to crop pests. Background technique [0002] Spiromesifen Molecular formula: C 23 H 30 O 4 . The mechanism of action of spiromethicone is to affect the development of whiteflies and mites, interfere with the biosynthesis of their liposomes, especially in the larval stage, and has a good activity in the larval stage. reproductive capacity, greatly reducing the number of eggs laid. [0003] Insecticidal ring, insecticidal double, and insecticidal single all belong to the nereid toxin class of insecticides. Neretoxin insecticides have contact and stomach poisoning effects, as well as certain systemic and fumigation effects, and can kill eggs. The poisonous effect on pests is relatively slow, and those with mild poisoning can sometimes be resurrected. It disappears quickly from the plant b...
