Abstract

Disclosed is an microemulsion of emamectin benzoate and cypermethrin, and its preparing process, wherein the microemulsion is prepared from the following constituents (by weight ratio): emamectin benzoate 0.01-10%, cyhalothrin 0.1-50%, cyclohexanone 10-20%, alkylphenol polyoxyethylene ether 0.1-20%, styrene phenol polyoxyethylene ether 0.1-20%, calcium dodecyl benzene sulphonate 0.1-20%, and balancing water.

Description

technical field [0001] The invention belongs to the technical field of pesticide compounding, and in particular relates to a compound insecticide of emamectin benzoate and cypermethrin and a preparation method thereof. Background technique [0002] Emamectin benzoate (emamectin benzoate), chemical name 4′-epi-methylamino-4′-deoxyabamectin benzoate, referred to as emamectin salt, is a kind of methylamino Abamectin (abamectin-aminomethyl) is a semi-synthetic antibiotic insecticide pesticide as a raw material. It is the latest low-toxic insecticide and acaricide that can replace highly toxic pesticides. Compared with other series of abamectin, the insecticidal effect of emamectin emamectin has been greatly improved, and it is suitable for the control of cotton bollworm, diamondback moth, sugar beet leaf moth, and litura leaf moth that are resistant to pyrethroids and organophosphates. , tea yellow mites and other pests of good insecticides. Emamectin emamectin exhibits extrem...
