Description

technical field [0001] The invention relates to an insecticide, specifically a microemulsion insecticide and a production process thereof, belonging to the field of microemulsion insecticides. Background technique [0002] With the widespread use of chemical pesticides, how to reduce environmental pollution and harm to humans and animals has attracted more and more attention. Therefore, reducing toxicity and improving drug efficacy is an inevitable trend in the development of pesticides. Compared with the original drug research and development, it is a more economical and quicker way to achieve the purpose of reducing toxicity and improving drug efficacy through dosage form research and development. 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 so...
