摘　　要：溴嘧草醚(代号:ZJ0777)为化学结构新颖的油菜田专用除草剂,为扩大其杀草谱,提高除草活性,我们以日本看麦娘(Alopecurus aequalis)和小藜(Chenopodiumalbum)等为试验靶标进行了与胺苯磺隆(Ethametsulfuron)混用的室内防除效果配方筛选研究,并采用共毒系数法和等效线法对二者混用的联合作用进行评价。结果表明,两者混用后表现相加或增效作用,最佳配比为溴嘧草醚∶胺苯磺隆质量比为1:0.2。ZJ0777 and Ethametsulfuron were used for rape to control weeds. Combining two compounds showed being a good way to widen the spectrum of weeds control for ZJ0777 and reducing residual phytotoxicity of Ethametsulfuron on rotational crops. Efficacy of combinations on Alopecurus aequalis, chenopodium album was tested, The results showed that the performance of a mixture of ZJ0777 and Ethametsulfuron were additive and synergism by two reference models.The optimal mass proportion was 1：0.2.
