水稻钻蛀性害虫之二化螟药剂筛选试验结果初报

摘要

为筛选生产上防治二化螟的有效药剂,2016年进行了田间药剂筛选试验.结果表明,10个药剂中以10%甲氧虫酰肼悬浮剂(制剂用量1200 g/hm2)对二化螟的防效最优,药后25 d的白穗率为1.9%,防效在92%以上,防效好于其他供试药剂,且持效期长.5%丁虫腈乳油(制剂用量1500 mL/hm2)、10%阿维·氟酰胺悬浮剂(制剂用量675 g/hm2)防效较好,其余药剂效果不太理想.%In order to screen excellent insecticides for controlling Chilo suppressalis, ten insecticides were tested in trials. The experimental results showed that methoxyfenozide 10% SC 1200 g/hm2 could control Chilo suppressalis effectively, with the control effect of 92.25%. The control effects of flufiprole 5% EC, abamectin + flubendiamide 10% SC on Chilo suppressalis were 72.54% and 73.24%.
