摘  要:
A novel and environmental friendly formulation of emamectin benzoate EW was prepared with the phase transfer method using polymer emulsifier and evaluated through its physical and chemical performances.The optimum formulation of emamectin benzoate 37 EW consisted of 3.7%(W/W) emamectin benzoate,5%cyclohexanone,5%xylene,2%dimethyl sulfoxide,the polymer emulsifier of 2.5%N-300 and 3.5%G-200,and water.The results indicated that the formulation was stable in room temperature,low temperature and thermal storage,and that the physical and chemical performances met the technical standard of oil-in-water emulsion.
