【摘要】 温室试验测定了4种常用除草剂助剂对磺草酮防除稗草和反枝苋的增效作用,同时也测定了在喷洒液中加入助剂后对玉米苗期的安全性。供试4种助剂分别为885、机油乳剂、药笑宝和信德宝。试验结果表明,4种常用除草剂助剂均不同程度地增加了磺草酮对稗草和反枝苋的防效;其中,药笑宝对供试除草剂的增效作用最为明显,其次是机油乳剂和885,信德宝的增效作用稍差。与磺草酮混用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。更多还原

【Abstract】 Experiments in greenhouse were done to test the enhancement of 4 adjuvants on the weed control of Sulcotrione.Their effect on the growth of maize seedling was also determined. Results showed that the herbicide adjuvants enhancedthe activity of sulcotrione differently on the control of Echinochloa crus-galli and Amaranthus retroflexus and Yaoxiaobaoshowed the best, while, the security of Sulcotrione with Yaoxiaobao on maize was the worst. Oil emulsion and 885showed a little less enhancement, but they were much better in the security.更多还原
