研究10%氟虫双酰胺.阿维菌素悬浮剂对稻纵卷叶螟的防治效果。结果表明:在主害代稻纵卷叶螟低龄幼虫高峰期,喷施1次10%氟虫双酰胺.阿维菌素悬浮剂,用量分别为450、600 mL/hm2,控虫保叶效果较好,药后3 d防效达71.28%、78.26%,药后14 d防效达99.75%、100.00%,药后14、20 d保叶效果分别达86.84%～89.91%、90.69%～90.81%,与对照药剂相当或优于对照药剂。施药1次即可有效控制稻纵卷叶螟的危害,达到控害、保叶、增产的效果。
Study on the Control Effect of 10% Flubendiamide and Abamectin Suspension for Rice Leaf Roller. The results showed that 10% flubendiamide and avermectin suspensions were sprayed on the main stage of the young larvae of C. medinalis at 450 and 600 mL / hm2, respectively, The control effect was 71.28% and 78.26% on the 3rd day after drug treatment, and the control effects reached 99.75% and 100.00% on the 14th day after drug treatment respectively. The leaf protection effects reached 86.84% ~ 89.91% and 90.69% ~ 90.81 %, Comparable to or better than the control agent. Application 1 times can effectively control the harm of rice leaf roller, to control damage, leaves, the effect of increasing production.
