摘　　要：以不同浓度5％锐劲特悬浮剂、20％三唑磷乳油和40％毒丝本乳油等3种药剂进行防治水稻稻纵卷叶螟田间药效试验。结果表明，在1～2龄幼虫高峰期，每公顷使用5％锐劲特悬浮剂300～600mL，对水稻稻纵卷叶螟的防治效果最高可达97．6％，且药效期长，防效明显优于20％三唑磷乳油等常用药剂。从使用成本与防治效果两方面综合考虑，生产上5％锐劲特悬浮剂的使用剂量以450mL／hm^2比较合适。Efficacy test of fipronit 50/00 SC, triazophos 20% EC and 40% dusiben against rice caseworm was carried out. The results indicated that the control effects of 5% fipronil SC at 300-600 mL/hm^2 on rice caseworm were obviously higher than those of triazophos 20% EC and the highest was 97. 6% with long efficiency during peak activity of 1-2 instar larvae. Considering the using cost and control effect of reagent,fipronil 5% SC at 450mL/hm^2 should be advised to use in practical application.
