Abstract

The invention discloses an insecticidal composition containing fluorine louse sulfanilamide and pyrethroids. The insecticidal composition comprises an active ingredient A and an active ingredient B, wherein the active ingredient A is selected from fluorine louse sulphanilamide, and the active ingredient B is selected from any one of the following compounds: lambda-cyhalothrin, ethofenprox, bifenthrin, fenpropathrin and tefluthrin; and the weight ratio of the active ingredient A to the active ingredient B is (1:80)-(60:1). The composition has higher activity towards various pests on various crops, has obvious synergism, expands the insecticidal spectrum and has the characteristics of small dosage, rain wash resistance and obvious synergism.

Description

Technical field [0001] The present invention belongs to the technical field of pesticides, and relates to the application of an insecticidal composition containing sulfonamides and pyrethroids on crop pests. technical background [0002] Pyrethroids are a kind of broad-spectrum insecticides that can control a variety of pests. Its insecticidal toxicity is 10-100 times higher than that of older generation insecticides such as organochlorine, organophosphorus and carbamates. Pyrethroids have a strong contact-killing effect on insects. Some species have gastric toxicity or fumigation effects, but none of them have systemic effects. Its mechanism of action is to disturb the normal physiology of insect nerves, causing them to die from excitement, spasm and paralysis. Because of its small dosage and low concentration, pyrethroids are safer to humans and animals and have little pollution to the environment. Its disadvantages are mainly high toxicity to fish and damage to certain benef...
