Insecticidal composition containing novaluron and carbamates

Abstract

The invention discloses an insecticidal composition containing novaluron and carbamates. The insecticidal composition comprises an active ingredient A and an active ingredient B, wherein the active ingredient A is the novaluron; the active ingredient B is any of the following compounds: indoxacarb, metolcarb, carbaryl and carbosulfan; and the weight ratio of the active ingredient A to the active ingredient B is 1:80-80:1. The composition can control various pests, has a remarkable synergistic effect, widens a bactericidal spectrum, and has higher activity on rice planthoppers, aphids, leafhoppers, Chilo suppressalis, Pectinophora gossypiella, cotton bollworms, beet armyworms, Plutella xylostella, cabbage caterpillars, Phyllocoptruta oleivora Ashmead, leaf miners, underground pests and the like on vegetables, fruit trees, cotton, rice and corn; the using amount of pesticides is reduced, the residual amount of the pesticides on crops is reduced, and the environmental pollution is reduced; and the insecticidal composition is safe to people and livestock, has high environmental compatibility, and ensures that pests cannot produce the pesticide resistance easily.

Description

technical field

[0001] The invention belongs to the technical field of pesticides and relates to an insecticidal composition containing fluorine urea and carbamate. Background technique

[0002] Chemical name of fluorourea (novaluron): (±)-N-[[[3-chloro-4-[1,1,2-trifluoro-2-(trifluoromethoxy)ethoxy]phenyl] Ammonia]carbonyl]-2,6-difluorobenzamide, molecular formula: C 17 h 9 CIF 8 N 2 o 4 , fluorourea is a new type of benzoylurea insect growth regulator, which can prevent the synthesis of chitin in the molting stage of insects during the growth process, thereby affecting the molting of insects, so that the pests cannot form new cuticles during molting, and the insects appear as insects. deformed and died. It can also regulate the growth and development of insects, inhibit molt metamorphosis, and inhibit the eating speed of pests, and has high ovicidal activity. It mainly enters the body of insects through insect feeding, and can also enter the body of insects through c...
