[目的]探寻有效防治水稻稻纵卷叶螟的药剂。[方法]用清水作对照,采用1.8%阿维菌素乳油450 g/hm2、40%毒死蜱乳油1 800 g/hm2、20%三唑磷乳油1 800 g/hm2和40%辛硫磷乳油1 500 g/hm2进行防治水稻稻纵卷叶螟的对比试验。[结果]施药15天后,1.8%阿维菌素乳油450 g/hm2和40%毒死蜱乳油1 800 g/hm2的防效分别为85.58%和86.80%,卷叶内有虫率均为0;40%辛硫磷乳油1 500 g/hm2的防效为79.60%,卷叶内有虫率为4.35%;20%三唑磷乳油1 800 g/hm2的防效最低,为72.45%。[结论]4种药剂均对稻纵卷叶螟有一定防治效果,且以1.8%阿维菌素乳油450 g/hm2和40%毒死蜱乳油1 800 g/hm2的防效最为明显。
[目的]探尋有效防治水稻稻縱捲葉螟的藥劑。[方法]用清水作對照,採用1.8%阿維菌素乳油450 g/hm2、40%毒死蜱乳油1 800 g/hm2、20%三唑燐乳油1 800 g/hm2和40%辛硫燐乳油1 500 g/hm2進行防治水稻稻縱捲葉螟的對比試驗。[結果]施藥15天後,1.8%阿維菌素乳油450 g/hm2和40%毒死蜱乳油1 800 g/hm2的防效分彆為85.58%和86.80%,捲葉內有蟲率均為0;40%辛硫燐乳油1 500 g/hm2的防效為79.60%,捲葉內有蟲率為4.35%;20%三唑燐乳油1 800 g/hm2的防效最低,為72.45%。[結論]4種藥劑均對稻縱捲葉螟有一定防治效果,且以1.8%阿維菌素乳油450 g/hm2和40%毒死蜱乳油1 800 g/hm2的防效最為明顯。

[Objective] The aim was to select pesticides on controlling Cnaphalocrocis medinalis Guenee.[Method] With water as CK,the compared experiment on controlling Cnaphalocrocis medinalis Guenee was conducted by using 1.8% abamectin EC 450 g/hm2,40% chlorpyrifos EC 1 800 g/hm2,20% triazophos EC 1 800 g/hm2 and 40% phoxim EC 1 500 g/hm2.[Result] The control effects of 1.8% abamectin EC 450 g/hm2 and 40% chlorpyrifos EC 1 800 g/hm2 were 85.58% and 86.80%,and both the rate of insects in the curled leaf were 0.The control effect of 40% phoxim EC 1 500 g/hm2 was 79.60%,and the rate of insects in the curled leaf was 4.35%.The control effect of 20% triazophos EC 1 800 g/hm2 was the lowest,only 72.45%.[Conclusion] Four pesticides had control effect and the effects of 1.8% abamectin EC 450 g/hm2 and 40% chlorpyrifos EC 1 800 g/hm2 were best.
