Embodiment 1
[0031] The emulsifiable concentrate compounded with beta-cyhalothrin and chlorpyrifos is composed of the following components by weight: beta-cyhalothrin 1%, chlorpyrifos 50%, compound emulsifier 22%, N,N-dimethyldecanamide 10%, the remainder is dimethyl carbonate;
[0032] The weight ratio of phenethylphenol polyoxyethylene ether sulfate, alcohol ether carboxylate and PEG-80 sorbitan laurate in the composite emulsifier is 1:5:5.
[0033] The preparation method comprises the following steps: adding the metered high-efficiency cyhalothrin and chlorpyrifos, N,N-dimethyl decylamide and dimethyl carbonate into the mixing kettle and stirring to dissolve them, and then adding phenethylphenol polymer. Oxyethylene ether sulfate, alcohol ether carboxylate, PEG-80 sorbitan laurate, supplemented with dimethyl carbonate, turned on the mixer, stirred evenly, filtered, and passed the quality inspection.
