摘　　要：[目的]探索2,4-D丁酯、异丙甲草胺与扑草净的增效作用。[方法]通过盆栽马唐、马齿苋等杂草,喷施混配制剂,筛选最佳配比。[结果]当2,4-D丁酯、异丙甲草胺、扑草净三者配比为20∶37∶8时增效作用最强。[结论]确认了混配的最佳比例,为田间试验提供理论依据。[ Objective ] For studying the synergism of 2,4-D butylate and metolachlor to prometryn. [ Method ] Screening of optimal proportion is obtained by spraying mixed preparation to weeds of potted digitaria, purslane, etc. [ Result] The strongest synergism is at the ration of 2, 4-D butylate, metolachlor and prometryn for 20： 37： 8. [ Conclusion] The research confirms the optimal ration of mixed preparation, and pro- vides the reference for fi＇eld trial.
