Abstract

The invention discloses a compound insecticidal composition containing bifenthrin and chlorpyrifos. The compound insecticidal composition contains the active ingredients bifenthrin and chlorpyrifos in a weight ratio of 1:80-60:1. The composition provided by the invention has a synergistic effect on a variety of pests harmful to agricultural production, reduces the dosage of pesticides, lowers the pesticide residue on crops, alleviates environmental pollution, is safe to human and livestock, has good environment compatibility, and is difficult for pests to generate drug resistance.

Description

technical field [0001] The invention belongs to the technical field of pesticides and relates to the application of a compound insecticidal composition containing bifenthrin and chlorpyrifos on crop pests. Background technique [0002] Bifenthrin chemical name: (1R,S)-cis(Z)2,2-dimethyl-3-(2-chloro-3,3,3-trifluoro-1-propenyl) Cyclopropanecarboxylic acid-2-methyl-3-phenylbenzyl ester, molecular formula: C 23 h 22 CIF 3 o 2 . Bifenthrin belongs to the class of pyrethroid insecticides and acaricides. It has contact and stomach poisoning effects, no systemic and fumigation effects, and has a wide insecticidal spectrum and rapid action. It does not move in the soil, is safer for the environment, and has a longer residual period. It is suitable for controlling lepidoptera larvae, whiteflies, aphids, leaf miners, leafhoppers, spider mites and other pests and harmful mites on cotton, fruit trees, vegetables, tea and other crops. It is used for the concurrent occurrence of inse...
