[目的]为了探寻有效防治水稻纵卷叶螟的药剂及组合。[方法]用清水作为对照(CK),采用48%毒死蜱EC 1 500 ml/hm2、2%阿维菌素EC600 ml/hm2、25%唑磷.毒死蜱EC1 500 ml+2%阿维菌素EC300 ml/hm2、50%毒.乙酰甲EC1 200 ml/hm2、25%唑磷.毒死蜱EC1 500 ml/hm2、50%敌.氟腈EC1 500 g/hm2进行防治水稻纵卷叶螟的对比试验。[结果]施药4 d后,以48%毒死蜱EC1 500 ml/hm2的防效最高,7 d和13 d后,以25%唑磷.毒死蜱EC1 500 ml+2%阿维菌素EC300 ml/hm2防效最佳,杀虫总效果和保叶效果均尤其突出。[结论]6种药剂均对水稻纵卷叶螟具有一定防治效果,且以25%唑磷.毒死蜱EC 1 500 ml+2%阿维菌素EC300 ml/hm2防效最为明显。
[Objective] The research aimed to explore the effective control of rice leaf roller and its combination. [Method] With CK as the control, 48% chlorpyrifos EC 1 500 ml / hm2, 2% abamectin EC 600 ml / hm2, 25% ml / hm2, 50% Toxicity. Acetyl EC1 200 ml / hm2, 25% Zooxanthin. Comparison of chlorpyrifos EC1 500 ml / hm2, 50% [Result] The control effect of 48% chlorpyrifos EC1 500 ml / hm2 was the highest after 4 days of application, with 25% of azadirachtin after 7 days and 13 days. EC1 500 ml + 2% abamectin EC 300 ml / hm2 best control effect, insecticidal effect and leaves are particularly prominent. [Conclusion] All the six kinds of pesticides had certain control effects on C. medinalis, and were most effective against 25% azadirachtin. EC1 500 ml + 2% abamectin EC 300 ml / hm2.
