Emamectin-benzoate aqueous emulsion

Abstract

The invention relates to a methylamino abamectin benzoate aqueous emulsion, which consists of methylamino abamectin benzoate, a solvent, a co-emulsifier, an emulsifier, a thickener, an antifreeze agent, an antifoaming agent and water, wherein the emulsifier is castor oil polyethenoxy ether, a mixture of the castor oil polyethenoxy ether and styryl phenol polyethenoxy ether, or a mixture of the castor oil polyethenoxy ether and ethylene oxide-propylene oxide segmented copolymers; the co-emulsifier is n-butyl alcohol, lauryl alcohol or a mixture of the n-butyl alcohol and the lauryl alcohol; the thickener is selected from one or a mixture of gum Arabic, polyvinyl alcohol, polyacrylate and magnesium aluminum silicate; and the antifreeze agent is glycerin. The methylamino abamectin benzoate aqueous emulsion solves the general problems of high water segregation rate, oil segregation, and the like in the aqueous emulsion, and has good product stability.

Description

technical field [0001] The invention relates to a pesticide, in particular to an emamectin benzoate emulsion in water, which belongs to the field of pesticides. Background technique [0002] With the use of chemical pesticides, the world's environment and ecological balance have been severely damaged. The toxicity, residue and environmental pollution of pesticides are very serious in our country. In order to solve this problem, on the one hand, we should strengthen the development of new pesticides with high efficiency, low toxicity, easy biodegradation and environmental compatibility. On the other hand, we must research, develop and use Green pesticide formulation. For a long time, pesticide emulsifiable concentrates have been an important dosage form of pesticide preparations, and emulsifiable concentrates contain a large amount of organic solvents, which have strict requirements on production, storage, transportation and use, otherwise poisoning or phytotoxicity will eas...

AI Technical Summary

Problems solved by technology

[0005] Emamectin benzoate has high activity, so the content of preparations is generally low. Currently, the market is mainly emulsifiable concentrate, which requires organic solvents such as xylene, which is easy to cause environmental pollution, waste resources and increase costs.
