Through the determination for water emulsion system of emamection benzoate with different formulation and the screening of emulsifiers, antifreeze agents and suspending adjuvant, the best formula of emamectin benzoate 5% EW and the appropriate processing technology were confirmed. By adding the water-phase into the oil-phase, better stability was obtained. The studies found that different salt content (1 000-5 000 mg/L) and different hardness (0-500 mg/L) of the water quality was almost no effect on stability of preparations, and the preparation showed good stability.
