10阿维∙茚虫威（艾酷）防治稻纵卷叶螟效果及应用技术

摘要

田间药效试验结果表明：10%阿维∙茚虫威水分散粒剂对稻纵卷叶螟具有较好的防治效果，其药效随着用药量的增加而极显著上升，药后9 d、16 d、25 d 450 g/hm2的处理对稻纵卷叶螟的综合防效分别为87.5%、95.2%、83.5%，与对照药剂10%阿维∙氟酰胺悬浮剂450 mL/hm2的处理防效相当，未达极显著差异。试验药剂综合表现为速效性较好、持效期较长，安全性好，因此在当前生产上有良好的推广应用前景。%Field efficacy trials indicated that 10% abamectin ­ indoxacarb WDG had good effect on controlling Cnaphalocrocis medinalis (rice leaf folder). Its insect preventing efficiency when the dose increased, with the respective efficiency up to 87.5%, 95.2%, and 83.5%after spraying for 9 d, 16 d, and 25 d (450 g/hm2), respectively, which had no significant differences from that using 10% abamectin­flutolanil (CK). In addition, 10% abamectin­indoxacarb WDG showed quick action, long duration, and safety. A regional application could be developed and promoted.
