摘要
2010和2012年,采用田间小区试验分别探索了氟虫双酰胺种子包衣处理、喷雾处理对水稻稻纵卷叶螟的实际防治效果。2010年试验结果表明,24%氟虫双酰胺水分散粒剂种子包衣处理对稻纵卷叶螟的控制作用较好,且持效期长。2012年试验结果表明,氟虫双酰胺不同剂型(20%悬浮剂、20%水分散粒剂)喷雾处理能有效防控该害虫危害,且持效性长达28d,药后7～28d卷叶防治效果分别为75.72%～97.21%、79.71%～97.43%;同时,该药剂对稻纵卷叶螟低龄及高龄幼虫的杀灭效果高,药后7～21d防治效果大于92%。
Field plot experiments were conducted to investigate control efficacies of flubendiamide with coating treatment of seed and spraying treatment on the rice leaf-roller, Cnaphalocrocis medinalis in 2010 and 2012, re- spectively. The results showed that high control efficacy against C. medinalis and excellent residual effect could be achieved with coating treatment of seed by 24% flubendiamide WG in 2010. C. rnedinalis was obviously controlled by 20% flubendiamide SC and 20% flubendiamide WG within 28 days after spraying treatment in 2012, and the control efficacies of leaf rolling were 75.72% -97.21% and 79.71% -97.43%, respectively, at 7-28 days after spraying treatment. Both young and old larvae of C. medinalis were effectively controlled by the above two for- mulations, and control efficacies were over 92% at 7-21 days after spraying treatment.
