中文摘要：
在大葱甜菜夜蛾初龄幼虫盛发期,用3种杀虫剂常规喷雾及其在药液中添加有机硅助剂Ag-64（倍效）进行处理。结果表明：甜菜夜蛾核型多角体病毒、甲氨基阿维菌素苯甲酸盐和氯虫苯甲酰胺分别减少药量25%、降低药液量50%、加入浓度0.1%的有机硅喷雾助剂Ag-64时,对甜菜夜蛾能够达到或优于其常规推荐剂量大容量喷雾的防治效果,且对大葱作物安全,初步分析认为与有机硅喷雾助剂Ag-64提高了药液在大葱叶片上的湿润性能有关。
英文摘要：
In order to explore the role of silicon surfactant on the control effect of beet armyworm（Spodoptera exigua）,S.exigua Nuclear Polyhedrosis Virus（SeNPV）,emamectin benzoate,and chlorantraniliprole were added silicon surfactant Ag-64（0.1 %）respectively,and 25 % effective dose,50 % spray volume were cut down for each insecticides in the meantime.Each treatment were sprayed at the peak of 1^st-3^rd instar larvae of Spodoptera exigua and the same or better control effects could be obtained,suggesting that the silicon surfactant could increase the moisture quality on the leaves of green Chinese onion（Allium fistulosum L.var.giganteum Makino）.
