Problems solved by technology

[0005] Pyrethrin pesticides are a class of insecticides that are currently used in large quantities at home and abroad. However, emulsifiable concentrates still account for the vast majority of pyrethroid pesticide preparations registered and used in my country, especially aromatic organic solvents. Long-term use will damage the environment. The power is huge, and there are no cost advantages and unsafe transportation and use

Abstract

The present invention discloses a pyrethroid pesticide aqueous emulsion and a preparation method thereof, wherein the pyrethroid pesticide aqueous emulsion comprises, by weight, 3-8% of 96% efficient cyhalothrin raw drug, 4-9% of epoxy fatty acid methyl ester, 6% of an emulsifier, and the balance of water. According to the present invention, the epoxy fatty acid methyl ester is adopted as the solvent in the formula, and the emulsifier N-300, the emulsifier G-100 and the fatty acid methyl ester sulfonate form the emulsifier, such that the pyrethroid pesticide aqueous emulsion has characteristics of good stability, good dispersion, easy degradation, low toxicity, low residue, and environmental protection.

Description

technical field [0001] The invention relates to the technical field of pesticide production, in particular to a pyrethroid pesticide emulsion in water and a preparation method thereof. Background technique [0002] Pesticides have dual effects on the environment. They are both environmental protectors and environmental polluters. Therefore, people seek to solve the environmental problems caused by pesticide formulations from various aspects. [0003] In the process of pesticide processing, some auxiliaries are generally added, and solvents and emulsifiers are the most important pesticide auxiliaries. However, traditional pesticide products use some toxic aromatic organic solvents, and the emulsifiers used are also some old varieties. Therefore, poor safety is the shortcoming of most pesticides, which bring serious harm to humans and the environment. [0004] With people's concern about food safety and environmental safety, coupled with the rising prices of some organic raw ...
