| 摘 要： | 田间试验示范结果表明,20%氯虫苯甲酰胺悬浮剂对稻纵卷叶螟有较好的防治效果,其药后14 d,8～12 ml/667m2杀虫效果为89.6%～92.2%,表现出较强的胃毒、触杀性,保叶防效为89.0%～93.5%,明显优于施用药剂40%毒死蜱乳油,建议在稻纵卷叶螟卵孵盛期和低龄幼虫高峰期进行防治。

| Abstract: | Results of field trial demonstrated that,20% chlorantraniliprole SC had a better control effect against cnaphalocrocis medinalis,which means 89.6%~92.2% at 8~12 ml/667m 2 after application in 14 days with strong stomach and contact toxicity,leaf control effect of the pesticide was 89.0%~93.5%,and was apparently superior to those of 40% emamectin benzoate.chlorpyrifos EW,control measurements were recommended to carried out at peak stage of egg hatch and low instar larvae of cnaphalocrocis medinalis. |
