Abstract:: Wet grinding technology was used and the optimum formulation of 10% fluorinated anthranilamide and avermectin water suspension was determined by the selection of dispersion mediums，emulsifiers and thickeners，and the particle size，suspension rate，dispersion of the suspension were tested.The results showed that the optimum formulation of water suspension of 10% fluorine anthranilamide avermectin was fluorinated anthranilamide 8 g，avermectin 2 g，magnesium aluminumsilicate 2 g，ethylene glycol (antifreeze) 4 g，defoamers 1 g，phenol ether phosphate salts TXPK 4 g，agricultural emulsifier 500# 2 g，pesticide emulsifier 1601# 2 g，water 75 g.The formulation was not layered obviously with a white or milky appearance；it had a good dispersion property in water，and all indexes were in line with the criterion of suspension after the formulation was stored under cold (0±1)℃ and heating (54±2)℃ conditions respectively.
