摘要：

为了筛选江淮地区大麦田有效除草剂，选用麦喜+唑啉草酯处理、高渗异丙隆、麦喜、唑啉草酯进行防除杂草的筛选试验。结果表明，麦喜可以有效防除大麦田阔叶杂草，唑啉草酯可以有效防除禾本科杂草；而以58 g/L麦喜悬浮剂150 mL/hm2+5%唑啉草酯乳油1200 mL/hm2防除阔叶及禾本科杂草总防效较好，60天总草株校正防效、鲜重防效分别达98.58%和98.77%，并且对大麦安全性好，可以在江淮地区大麦田推广应用。

Abstract:

Control effect of Derby, pinoxaden and isoproturon was investigated in barley field weeds of Jianghuai region. The results showed that, the effect of Derby was better for broadleaf weeds and pinoxaden was better for grass weeds in barley field weeds. Chemical control by the does 150 mL/hm2 of Derby 58 g/L SC plus 1200 mL/hm2 of pinoxaden 5% EC was the best. At 60 days after, correction control effect and fresh weight inhibition rate were 98.58% and 98.77%. Furthermore, it was safety and could be used as pre-emergence herbicides for extensive in barley field of Jianghuai region.
