摘要： 采用湿磨法，选用适量的两种表面活性剂、增稠剂、防冻剂等分别制成48%乙草胺.莠去津悬乳剂和48%丁草胺.莠去津悬乳剂，可解决用同类药剂配制可湿性粉剂含量低的问题，而且其物理和应用性能优于可湿性粉剂和悬浮剂。田间试验表明，两种悬乳剂对夏玉米地主要杂草──马唐的防除效果优于莠去津单用，残留量符合标准。

Abstract: Described in this paper is the right dosage of surface active agents,sticking agents, anti-frostbite agents used in the preparation of two suspoemulsions containing 48% mixture of atrazine and butachlor or acetochlor through the wet grind method. The formulation increased the content of active ingredients in the two preparations. Their physical properties and application performances were better than those of the corresponding wettable powders and suspension concentrate. The results of field experiments indicated that the application of the two suspoemulsions exercised better control over Digitaria sanguinalis,a main weed in summer corn fields,than the single application of atrazine. Their atrazine residues conformed with the standards.

Key words: Herbicide mixture, Atrazine, Acetochlor:Butachlor
