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。
Results of field trial demonstrated that, 20% chlorantraniliprole SC had a better control effect against cnaphalocrocis medinMis, which means 89.6%-92.2% at 8-12 ml/667m2 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 ofcnaphalocrocis medinalis.
