目的]探讨10%氟虫双酰胺·阿维菌素悬浮剂对稻纵卷叶螟的防治效果和使用技术。方法]测定了10%氟虫双酰胺·阿维菌素悬浮剂300、450、600 ml/hm23个施用量对稻纵卷叶螟的田间防治效果。结果]10%氟虫双酰胺·阿维菌素悬浮剂对稻纵卷叶螟具有较好的防治效果。药后3 d,10%氟虫双酰胺·阿维菌素悬浮剂用药300、450、600 ml/hm2对稻纵卷叶螟幼虫的防治效果分别为94.91%、96.11%和96.84%;药后7 d的防治效果分别为96.45%、99.23%和99.36%;药后14 d对水稻的保叶效果分别为97.97%、98.38%和98.49%。结论]为该药剂的进一步推广应用及水稻害虫的控制提供了参考。

Control Effect of 10% Flubendiamide · abamectin Suspension Concentrate against Cnaphalocrocis medinalis （Guen~e）

Objective ] The aim was to understand control effect of 10% Flubendiamide ~ abamectin suspension concentrate against C. medinal/s and using technology. Method] Control effect of 10% Flubendiamide · abamectin suspension concentrate at 300,450 and 600 ml/hm2 against C. medinalis in field were determined. Result] 10% Flubendiamide · abamectin suspension concentrate had better effect on C. medinalis. The control efficiencies of 10% Flubendiamide · abamectin suspension concentrate at 300,450 and 600 ml/hm2 against C. medinalis in field were 94.91%, 96.11% and 96.84% after three days of treatment, and were 96.45%, 99.23% and 99.36% after seven days of treatment, meanwhile the leave protecting effects were 97.97%, 98.38% and 98.49% after 14 days of treatment. Conclusion] The research results provide reference for further popularization and application of 10% Flubendiamide · abamectin suspension concentrate and control of rice pests.
