Abstract

An aquatic emulsion for preventing and treating the pests of rice, fruit tree and warehouse is prepared from fenobucarb or carbosulfan or pirimiphos-methyl, emulsifier, thickening agent, antifreezing agent, and stabilizer and deionized through dissolving or fusing, homogenizing and dispersing. Its advantage is no environmental pollution.

Description

technical field [0001] The invention relates to an aqueous emulsion of pesticides secbutacarb, carbosulfan and pirimiphos-methyl and a preparation method thereof. Background technique [0002] Zhongdingwei ISO common name: fenobucarb. Chemical name: 2-sec-butylphenyl-N-methylcarbamate [0003] Structural formula: [0004] [0005] The pure product has a melting point of 33-34°C, 660mg / l in water at 30°C, and is easily soluble in general organic solvents, such as acetone, chloroform, benzene, toluene, xylene, etc. Unstable to alkalis and strong acids. It can be used to control rice planthoppers, thrips, leafhoppers, rice stem borers, rice leaf rollers, aphids, fruit tree borers and other pests on rice, vegetables, cotton, fruit trees and other crops, mainly by inhibiting acetylcholinesterase. Pests die from poisoning, have a strong contact effect on pests, and have certain stomach poisoning, fumigation and ovicidal effects. [0006] Carbosulfan’s English common name i...
