摘要
选用环虫酰肼5%悬浮剂1 800 m L/hm2,氯虫苯甲酰胺20%悬浮剂150 m L/hm2,阿维菌素1.8%乳油1 500m L/hm2进行药效对比试验防治稻纵卷叶螟。试验结果表明:环虫酰肼5%悬浮剂1 800 m L/hm2,氯虫苯甲酰胺20%悬浮剂150 m L/hm2对稻纵卷叶螟有较好的防效,两者药后14 d防效分别为91.3%、90.2%,且对水稻生长安全,对其他有益生物未见药害。建议使用时,用环虫酰肼5%悬浮剂1 800 m L/hm2或氯虫苯甲酰胺20%悬浮剂150 m L/hm2于水稻稻纵卷叶螟1龄幼虫高峰期兑水6 750 L在水稻叶面均匀喷雾。
The effects of 3 insecticides against Cnaphalocrocis medinalis Guenee in rice field trials were evaluated. The results showed that the control efficiency of 5% chromafenozide and 20% chlorantraniliprole was 91.3% and 90.2%, respectively, after 14 days. These insecticides had no worse effect on rice and beneficial arthropods. We suggest to spread 5% chromafenozide SC（120 m L/667m2） or 20% chlorantraniliprole（10 m L/667 m2） with 450 L water to counter C. medinalis.
