摘　　要：在温室条件下研究了5种常用除草剂助剂油酸甲酯助剂、药笑宝、885、机油乳剂和信德宝对磺草酮防除稗草、牛筋草、马唐、反枝苋、马齿苋和苘麻的药效增强作用以及对玉米苗期生长的安全性。结果表明,5种常用除草剂助剂均不同程度地增加了磺草酮对供试6种杂草的防效,油酸甲酯助剂和药笑宝对磺草酮药效增强作用最大,其次是885和机油乳剂,信德宝的增效作用稍差。而助剂与磺草酮混用后对玉米的安全性由高到低依次是机油乳剂、信德宝、885、药笑宝、油酸甲酯助剂。Greenhouse studies were conducted to investigate the enhancement effect of five herbicide adjuvants on sulcotrione when controlling Echinochloa crusgalli L., Eleusine indica （L.） gaertn, Digitaria adscendens （H.B.K.）, Henrard, Amaranthus retroflexux L., Portulaca oleracea L. and Abutilon theophrasti Medic. And studies also include crop safety to corn seedling. Results showed that the five herbicide adjuvants enhanced the activity of sulcotrione differently, Methyl oleate adjuvant and Yaoxiaobao had the best enhancement effect on sulcotrione, while the safety of sulcotrione with methyl oleate adjuvant and Yaoxiaoba on corn were the worst. Oil emulsion and 885 took second place, and the Synertrol had the worst enhancement. The Oil emulsion had the best safety.
