摘要

田间药效试验结果表明,25%甲维.毒死蜱EW对稻纵卷叶螟有较好的防治效果,使用25%甲维·毒死蜱EW 60～80 ml/667m2药后16 d防效为73.85%～82.01%,与对照药剂1%甲氨基阿维菌素苯甲酸盐EC 60 ml/667m2防效79.99%和40%毒死蜱EC 100 ml/667m2防效76.01%相当或略高,能有效控制稻纵卷叶螟的发生为害,可以推荐使用。%Results of field efficacy trial showed that, 25% emamectin benzoate.chlorpyrifos EW had a better control effect against cnaphMocmcis medinalis, which means 73.85%-82.01% at 60-80 ml/667m2 after application in 16 days, and that was the same or slightly higher to CK pesticides： 1% emamection-benzoate EC at 60 ml/667m2 with control effect of 79.99% and 40% chlorpyrifos EC at 100ml/667m2 with control effect of 76.01%, that is to say, cnaphalocmcis medinalis could be effectively controlled with 25% emamectin benzoate.chlorpyrifos EW, and the pesticide was recommended for application.
