摘　　要：室内生测结果表明,供试的5种水田除草剂中,丙草胺对稗草的活性最高,苯噻草胺对稗草的活性最低,莎稗磷、二甲戊灵和丁草胺居中,且三者对稗草的活性相当;二甲戊灵对稻稗的活性最高,丁草胺对稻稗的活性最低,莎稗磷、苯噻草胺和丙草胺对稻稗有较好的防除效果。s： Efficacy of Five herbicides on barnyardgrass and water barnyardgrass was studied in greenhouse. The results showed that pretilachlor had the highest activity to barnyardgrass among the five herbicides and mefenacet had a relatively low activity. Pendimethalin had the highest activity to water barnyardgrass and then anilofos, mefenacet and pretilachlor. Butachlor had a relatively low activity on water barnyardgrass.
