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
