The optimum formulation of 10% bifenthrin emulsion in water（EW）was developed by the screening of the solvent and surfactant through the orthogonal experiment.The optimum solvent was 18% dimethylbenzene,the optimum surfactants of 602# and Tween-20 and 500# were 3% and 2.5% and 2%,the ethanediol was 4%,the organic silicon defoamer was 0.2%,the other component was deionized water.The best productive technology of 10% bifenthrin EW was that the shearing speed was 6 000 r/min,and the shearing time fixed on 4 mins.The pH was 5.7～6.5,there were not oil slick,precipitation,the stability of the bifenthrin EW was up to grade.The formulation had been stored at the temperature（54±2）℃for14 days with the resolution ratio 1.5%,its surface tension was low enough,and good pourability it had.
