褐飞虱是水稻主要害虫之一,近年来褐飞虱对防治药剂产生了一定的抗药性。为寻求防治褐飞虱有效新药剂,利用比较方法,进行燕化吡蚜酮.烯啶虫胺（以下简称燕化扫飞）防治晚稻褐飞虱小区试验。试验结果表明,药后7d,燕化扫飞12g、燕化扫飞9g＋敌敌畏150ml、吡蚜酮24g、立本烯啶虫胺30g防效分别为94.8%、93.8%、91.5%、91.1%;燕化扫飞对褐飞虱防治效果较好,优于敌敌畏、吡蚜酮、立本烯啶虫胺,是防治褐飞虱的好药剂,可以在大田推广应用。生产上用量以12g/667m2为佳,药后3d防效达92.3%,7d防治效果可达94.8%。

Brown paddy plant hopper is one of the major pests in rice,which has engendered certain pesticide-resistance in recent years.In order to choose better new pesticide for controlling it,a comparison experiment was conducted based on ＂Yanhua Saofei＂ application.The results showed that the effect rates of ＂Saofei＂ 12g,＂Saofei＂ 9g＋ dichlorvos 150ml,Pymetrozine 24g and ＂Liben＂ 30g reached to 94.8%,93.8%,91.5%,91.1% respectively.So that ＂Saofei＂is the best pesticide among them for the hopper and can be extended in large scale.In field application,the recommended dosage 12g/667m2,the controlling effect will be 92.3% three days after application,and 94.8% seven days after application.
