| Abstract: | The faded rate of the population and the efficacy of phoxim 8% ME at different concentration 1-3 day after sprayed pesticide against aphid and Prodenia litura were investigated using whole-plant bioassay.The results showed that the efficacy of Phoxim 8% ME at 375 g ai./hm2against aphid was obviously better higher than that of phoxim 40% EC at 375 g ai/hm2,and the efficacy of Phoxim 8% ME at 93.75-187.5 g ai./hm2was equal to that of phoxim 40% EC at 375 g ai/hm2.The efficacy of Phoxim 8% ME at 400 g ai./hm2 against Prodenia litura was equal to that of phoxim 40% EC at 400 g ai/hm2.Phoxim 8% ME had better efficacy against aphid and Prodenia litura,was applicable against aphid and Prodenia litura in the cruciferae vegetables. |
