| 摘 要： | 进行6种农药防治水稻稻纵卷叶螟的田间药效试验，结果表明：200g／L氯虫苯甲酰胺悬浮剂、25g／L多杀霉素悬浮剂、240g／L氰氟虫腙悬浮剂、50g／L虱螨脲乳油、100g／L虫螨腈悬浮剂、500∥L丙溴磷乳油等6种农药对水稻稻纵卷叶螟的卷叶防效达61．11％～88．58％，虫口防效达51．99％～97．35％。其中240g／L氰氟虫腙悬浮剂的卷叶防效最好，每667m２用100g和130g处理的防效分别为88．58％和87．65％。6种供试农药在试验剂量范围内均对水稻安全无药害，可替代高毒农药防治水稻稻纵卷叶螟。

| Abstract: | A trial on control efficacy of 6 pesticides against Cnaphalocrocis medinalis was conducted under field condition. The results showed that the control efficacies of 200 g/L chlorantraniliprole（ SC）, 25g/L Spinosad（SC）, 240 g/L metaflu- mizone（SC）, 50 g/L lufenuron（EC）, 100 g/L chlorfenapyr（ SC ）, 500 g/L profenofos （EC） on Cnaphalocrocis medinalis reached 61.11% -88.58%, the controlling effects of pest population were 51.99% -97.35%. Among which, 240 g/L metaflumizone（SC） showed the best effect on controlling Cnaphalocrocis medinalis, and the efficacy were 88.58% and 87.65 %, respectively, when applied 100 g and 130 g per 667 m2. In this experiment, 6 pesticides were tested under reason- able dosages, which were safe to rice production and could be used to substitute the high toxic pesticides for controlling Cnaphalocrocis medinalis. |
