The soil life of herbicidally active thiolcarbamates is extended by employing in combination therewith certain organophosphorus compounds having the formula 3 <IMAGE> in which R4 is selected from the group consisting of C1-C4 alkyl and C1-C4 alkoxy; R5 is selected from the group consisting of C1-C4 alkyl, C1-C4 alkoxy, C1-C4 alkylthio, C2-C4 alkenylthio and C2-C4 alkynylthio; R6 is selected from the group consisting of hydrogen , C1-C10 alkyl, C5-C7 cycloalkyl and phenyl; and R7 is selected from the group consisting of C2-C4 alkenyl, C1-C10 alkoxy, C1-C10 alkylthio, C2-C6 alkynoxy, C2-C5 carbalkoxy, phenyl, phenoxy, (C1-C3 alkoxy)phenyl, benzyl and benzyloxy, all optionally substituted with up to two halogen atoms.
