摘　　要：[目的]为了筛选防治稻飞虱的有效药剂。[方法]用清水作为CK,对5%锐劲特悬浮剂、40%毒死蜱乳油、3%啶虫咪和10%大功臣可湿性粉剂进行防治稻飞虱的对比试验。[结果]施药3 d和7 d后,均以毒死蜱1 200 ml/hm21、050 ml/hm2的防效最佳,防效分别达到76.70%7、2.94%、90.88%和86.32%。施药14 d后,锐劲特防效最高,3种剂量下防效分别为91.72%8、5.25%、81.01%。[结论]4种药剂防治稻飞虱,毒死蜱防效最好,具有速效性和持效性;锐劲特持效性好;啶虫咪和吡虫啉效果较差。[Objective] The study aimed to select the effective pesticides on controlling planthopper, [Method] With water as CK, the compared expefiwent on controlling planthopper with 5% regent suspending agent, 40% chloipyrifos cream, 3% acetamipfid and imidaclopfid 10% WP was conducted, [Result] The control effects of 1 200 ml/hm^2 and 1 050 ml/hm^2 chloipyrifos were best after using pesticides for 3 and 7 days, being 76.70%, 72.94%, 90.88% and 86.32% respectively. The control effect of regent was highest after using for 14 days. The control effects of 3 dosages were 91.72%, 85.25 % and 81.01% respectively. [ Conclusion] Among 4 pesticides, the control effect of chloipyrffos was best, quick and persistent. The residual effect of regent was best and the effects of acetamiprid and imidacloprid were worst.
