Embodiment 1

[0014] A kind of acephate pesticide, each component by weight: 100 parts of acephate, 5 parts of hexaflumuron, 20 parts of cyhalothrin, 0.5 parts of stabilizer, 5 parts of emulsifier and 20 parts of toluene solvent share. The emulsifier is one or more of nonylphenol polyoxyethylene ether, alkylbenzene calcium sulfate, and styrene-ethylphenyl polyoxyethylene-polyoxypropylene ether.

[0015] The preparation process of acephate comprises the steps:

[0016] (1) Put methamidophos and chloroform into the reaction kettle according to the molar ratio of 1:1, stir evenly, then add acetyl chloride dropwise, the molar ratio of methamidophos and acetyl chloride is 1:1.5, and control the vacuum -0.04MPa, the hydrogen chloride gas released by the reaction is absorbed by water to produce hydrochloric acid; (2) After the reaction is completed, the obtained reaction solution is subjected to precipitation, the precipitation temperature is 70-75°C, the vacuum is -0.15MPa, and the precipitation...

Abstract

The invention provides an acephate pesticide. The components are calculated in parts by weight: 100-150 parts of acephate, 5-15 parts of hexaflumuron, 20-30 parts of cyhalothrin, and 0.5 parts of a stabilizer 1.5 parts, 5-8 parts of emulsifier and 20-50 parts of toluene solvent. The invention has the characteristics of high efficacy, good stability, little environmental pollution and the like.

Description

technical field [0001] The invention relates to the field of pesticide manufacturing, in particular to an acephate pesticide. Background technique [0002] Acephate, also known as acephate, is a low-toxicity insecticide. Acephate is a systemic insecticide, which has stomach poisoning and contact killing effects, and can kill eggs. It has a certain fumigation effect and is a slow-acting insecticide. It is suitable for vegetables, tea trees, tobacco, fruit trees, cotton, etc. [0003] Flowers, rice, wheat, rapeseed and other crops, control a variety of chewing, piercing and sucking mouthpart pests, harmful mites and sanitary pests. Improper storage and use can cause human and animal poisoning. [0004] Mix heterogeneous pesticides to make a compound agent, which can complement each other in efficacy, kill insects with multiple mechanisms, expand the scope of insecticide, reduce drug resistance, and improve comprehensive control benefits. The compound agent has better applica...
