Abstract

The invention belongs to the technical field of pesticide compounding, and particularly relates to fenitrothion containing missible oil and an application thereof. The effective components of the fenitrothion containing missible oil are theta-cypermethrin and fenitrothion, wherein the weight ratio of the fenitrothion to the theta-cypermethrin is 1:1-20: 1. The fenitrothion containing missible oil has a particular effect on prevention and treatment of pink rice borer through the synergistic effect of the components.

Description

technical field [0001] The invention belongs to the technical field of compounding pesticides and insecticides, and specifically relates to an emulsifiable concentrate containing fenitrothion and its application. Background technique [0002] Fenitrothion [0003] It is an organophosphorus insecticide. Moderate toxicity, low toxicity to humans and animals, the acute oral LD50 of rats is 400-800 mg / kg, and the acute percutaneous LD50 of rats is 1200 mg / kg. Fenitrothion has contact killing and stomach poisoning effects, no systemic and fumigation effects, medium residual effect period, wide insecticidal spectrum, special effect on Lepidoptera larvae, and can also control Hemiptera, Coleoptera and other pests. The drug is stable to light, and it is easy to decompose and fail when exposed to high temperature. It is hydrolyzed in alkaline medium, and iron, tin, aluminum, copper, etc. will cause the drug to decompose. It can be stored in glass bottles for a long time. [0004] ...
