AI Technical Summary

Problems solved by technology

[0003] However, the current microemulsion products often have problems such as stratification, crystallization, turbidity, and flocs in the market, especially in the north of -20 ° C, such as Heilongjiang, Inner Mongolia and other regions, there will also be freezing phenomena, which greatly affects Influenced the development of this dosage form in the field of pesticide technology
In addition, the organic solvents added in the microemulsion--stupid solvents such as toluene, xylene and benzene, etc., have serious environmental pollution.

Description

technical field [0001] The invention relates to an insecticide, in particular to a microemulsion insecticide and a production method thereof, belonging to the field of microemulsion insecticides. Background technique [0002] With the extensive use of pesticides, it has brought serious pollution to the natural environment, which has aroused widespread concern from relevant parties. Especially in today's increasingly perfect environment and strict requirements, the call for reducing pesticide pollution is getting stronger and stronger. The pollution caused during the application of pesticides includes drifting and scattering of pesticide ingredients themselves, poisoning caused by soil erosion, residues on crops and fruits, and a large number of supplementary ingredients in preparations such as toxic organic solvents. In recent years, in the United States and other countries, the restrictions on the use of organic solvents in pesticide preparations have become increasingly s...
