Abstract

The invention relates to high-performance cyhalothrin pesticide aqueous emulsion and a preparation method thereof. The aqueous emulsion is prepared by mixing the following raw materials by weight percent: 2.5 to 10 percent of high-performance cyhalothrin, 10 to 70 percent of Jatropha seeds biodiesel, 3 to 10 percent of emulphor, 0.5 to 4 percent of high-performance cyhalothrin solvent and the balance of water. The pesticide aqueous emulsion has the advantages that the environment pollution is small, the characteristic is stable, the pesticide aqueous emulsion can be diluted by 2000 to 2500 times of water, can tolerate the temperature of 0 to 65 DEG C, the aqueous emulsion is not layered, the combination of the high-performance cyhalothrin and the Jatropha seeds biodiesel has synergism to the high-performance cyhalothrin, and the aqueous emulsion is suitable for large-scale generalization and application.

Description

technical field [0001] The invention relates to a pesticide water emulsion, in particular to a pesticide water emulsion containing beta-cyhalothrin and a preparation method of the water emulsion. Background technique [0002] The main method for humans to prevent and control agricultural and forestry diseases and insect pests is to use chemical control. Chemical pesticides play a very important role in increasing agricultural production and income. Organic solvents such as toluene and xylene have brought serious pollution to the natural environment. Today, with stricter environmental protection requirements, the international call for reducing pesticide pollution is becoming stronger and stronger. It is not appropriate to vigorously develop old formulations such as EC and WP. , there is an urgent need to develop some safe and efficient new dosage forms, so many new dosage forms such as microemulsions, suspension concentrates, water solvents, microcapsules, water-dispersible ...
