Herbicidally active thiolcarbamates are employed in combination with certain 4-phenyl-1,2,3-thiadiazoles having the formula <IMAGE> in which R4 is selected from the group consisting of trifluoromethyl and <IMAGE> in which R5 is selected from the group consisting of C1-C3 alkyl, phenyl, and phenyl substituted with one or more members selected from the group consisting of halogen and trifluoromethyl. In a typical application, the 4-phenyl-1,2,3-thiadiazole is 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.
