摘　　要：为筛选防治稻纵卷叶螟的混用和复配药剂,在三亚市进行了不同药剂对稻纵卷叶螟的田间药效试验。结果表明,每公顷使用10%氟铃·毒死蜱(酷锐)1500mL+50%丙溴磷600mL的速效性最好,药后1d防效达到97.74%,其持效期也较好,药后7d防效达100.00%;试验中使用的其他单剂或复配药剂对稻纵卷叶螟的防治效果也比较理想,可用于对稻纵卷叶螟的轮换防治。The present study was conducted to screen mixed application pesticides or compound pesticides for controlling rice leaf roller（Cnaphalocrocis medinalis Guenee）.Nine treatments of different pesticides,viz.,hexaflumuron·chlorpyrifos（10%）,abamectin EC（10%）,chlorpyrifos EC（10%）,methomyl（20%）,profenofos（50%）,and water were applied on rice under field conditions in Sanya City,Hainan,on Jun.3,2009.The methomyl（20%） was used as the check.The results showed that 150mL hexaflumuron.chlorpyrifos（10%） with 600mL profenofos（50%） per hectare had the best and persistent control effects with 97.72% control efficiency after one day and 100% after 7 days.The other pesticides also had a good control effect on rice leaf roller and could be used to control rice leaf roller.
