Abstract

The invention discloses an insecticidal composition containing spiromesifen and afidopyropen and application of the insecticidal composition, the insecticidal composition comprises an effective component A and an effective component B, the effective component A is spiromesifen, the effective component B is afidopyropen, the mass ratio of spiromesifen to afidopyropen is 30: 1-1: 30. The insecticidal composition has the characteristics of expanding the insecticidal spectrum, improving the prevention and control effect, prolonging the application period, reducing the dosage, reducing the phytotoxicity, reducing the residue, delaying the drug resistance of pests, delaying the occurrence of drug resistance and the like.

Description

technical field [0001] The invention relates to the technical field of plant protection, in particular to an insecticidal composition containing spiromethin and dipropacyclopyrene and application thereof. Background technique [0002] Spiromesifen is a spirotetronic acid insecticide and acaricide developed by Bayer. It is mainly used to control whitefly and aphids in cotton, vegetables and ornamental plants. It can affect the development of whiteflies and mites, interfere with the biosynthesis of their liposomes, and at the same time produce ovariectal closure, reducing the reproductive capacity of mites and whitefly adults. CAS number: 283594-90-1, chemical structure: [0003] [0004] Afidopyropen mainly prevents pests from eating quickly through stomach poisoning and contact killing, leading to starvation death of pests. It can control a variety of piercing-sucking pests such as aphids, whiteflies, leafhoppers, psyllids, scale insects and planthoppers. CAS number: ...
