Herbicidally active thiolcarbamates are employed in combination with certain organophosphorous compounds having the formula <IMAGE> in which R4 is selected from the group consisting of C1-C4 alkyl, C1-C4 alkoxy and C1-C4 alkylthio; R5 is selected from the group consisting of C1-C4 alkoxy and C1-C4 alkylthio; R6 is selected from the group consisting of C2-C6 alkylene and C2-C6 alkenylene; R7 is selected from the group consisting of hydrogen, phenyl, C1-C4 alkyl and C2-C4 alkenyl, all optionally substituted with up to two halogens; X is oxygen or sulfur; and n is zero or one. As a result, the herbicidal effectiveness of the thiocarbamate is enhanced and prolonged, rendering a single application of the herbicide effective over a longer period of time.
