Problems solved by technology

The fenpropathrin products sold on the market are mainly emulsifiable concentrate formulations, which use a large amount of organic solvents, which is not conducive to reducing production costs and reducing environmental pollution. In addition, the production, storage and transportation of the finished products are poor in safety, and the spreading, wetting and penetration of the liquid medicine The performance is not good, and its dosage form does not meet the requirements of the development trend of pesticides
So far, there is no report on the patent of fenpropathrin microemulsion

Abstract

The invention discloses a fenpropathrin microemulsion and a preparation method thereof. The fenpropathrin microemulsion which can kill pests and mites takes fenpropathrin as the active principle and is characterized that water is used as solvent and synergistic agent also can be added to enhance the pesticide effect. The invention has the characteristics of reduced toxicity and cost, high prevention effect, little pollution, and the like, and can replace corresponding emulsifiable concentrate preparation for preventing and treating pests and mites.

Description

technical field [0001] The invention relates to a new formulation of insecticidal and acaricidal pesticides, in particular to a fenpropathrin microemulsion and a preparation method thereof. Background technique [0002] A fenpropathrin microemulsion and a preparation method thereof. [0003] Chemical name: (R,S)-2-cyano-3-phenoxybenzyl-2,2,3,3-tetramethylcyclopropanecarboxylate. [0004] English name: fenpropthrin [0005] Molecular formula: C 22 h 23 NO 3 [0006] Structural formula: [0007] [0008] A kind of pyrethroid insecticide and acaricide, which has contact killing, stomach poisoning and repelling effects, has no systemic and fumigation effects, can kill larvae, adults and eggs, is effective for a variety of mites, and has a moderate degree of persistence in the field The effect is better at low temperature. At the initial stage of its launch on the market, it quickly occupied the pesticide market due to its high efficiency, low toxicity, and low dosage,...
