Herbicidally active thiolcarbamates are employed in combination with certain amine oxanilic acid salts having the formula <IMAGE> in which R is selected from the group consisting of C1-C6 alkyl, C2-C6 alkenyl, phenyl and benzyl, and a and b are both integers from zero to four such that the sum of a and b is four. In a typical application, the amine oxanilic acid salts are included in sufficient quantity to lessen the rate of soil degradation of the thiolcarbamate. As a result, the herbicidal effectiveness of the thiolcarbamate is enhanced and prolonged, rendering a single application of the herbicide effective over a longer period of time.
