Abstract

The invention belongs to the technical field of pesticide compounding and particularly relates to a cyfluthrin-containing composition and application thereof. According to the cyfluthrin-containing composition, effective ingredients are liuyangmycin and cyfluthrin. The compounded composition has the advantages that the problem of generation of pest resistance is effectively resisted, and the current problem of pest drug resistance is relieved to the maximum, so that the dosage of a pesticide is reduced, and the influence on the environment is relieved.

Description

technical field [0001] The invention belongs to the technical field of compounding pesticides and insecticides, in particular to a composition containing cyfluthrin and its application. Background technique [0002] Cyfluthrin [0003] BESTRUCTUR; BESTRETHIN, RENTATHIN (RS) α-CYANO-4-FLUORO-3-PHENOXYBENZYL(1RS,3RS; 1RS,3RS)-3-(2,2-DI Chlorovinyl)-2,2-dimethylcyclopropanecarboxylate. [0004] [Density] 1.27~1.28; [Melting point (℃)] 60 (industrial product); [Toxicity LD50 (mg / kg). [0005] The acute oral LD50 of rats is about 500, and that of mice is 450. Rats were fed with an ineffective dose of 125mg / kg feed for 90 days. The pure product is a viscous, partially crystalline amber oil. With contact and stomach poisoning effect, long-lasting. [0006] Liuyangmycin [0007] It is an antibiotic with a macrocyclic lactone structure produced by Streptomyces griseus Liuyang varietal. It is a low-toxicity, low-residue, broad-spectrum acaricide that can prevent and control ...
