高氰戊菊酯与氧乐果以不同的比例混配对菜蚜的毒力测定表明，都有不同程度的增效作用，综合评价以1：3配比最佳，共毒系数为426．73。田间药效试验证明对多种蚜虫均表现出显著的增效作用，最佳使用浓度为75～150PPm，且表现出低浓度比高浓度增效明显的趋势。
The results showed that all of the synergistic effect of the mixture of the high-activity fenvalerate and the omethoate on the aphids in the cabbage had different synergism. The comprehensive evaluation was the best with the ratio of 1: 3, the co-toxicity coefficient was 426.73 . The field efficacy test showed that all kinds of aphids showed a synergistic effect, the best concentration of 75 ~ 150PPm, and showed a low concentration of higher concentration than the obvious synergistic trend.
