ABSTRACT:
The soil life of herbicidally active thiolcarbamates is extended by employing in combination therewith certain organophosphorus compounds having the formula 3 ##STR1## in which R.sup.4 is selected from the group consisting of C.sub.1 -C.sub.4 alkyl and C.sub.1 -C.sub.4 alkoxy; R.sup.5 is selected from the group consisting of C.sub.1 -C.sub.4 alkyl, C.sub.1 -C.sub.4 alkoxy, C.sub.1 -C.sub.4 alkylthio, C.sub.2 -C.sub.4 alkenylthio and C.sub.2 -C.sub.4 alkynylthio; R.sup.6 is selected from the group consisting of hydrogen , C.sub.1 -C.sub.10 alkyl, C.sub.5 -C.sub.7 cycloalkyl and phenyl; and R.sup.7 is selected from the group consisting of C.sub.2 -C.sub.4 alkenyl, C.sub.1 -C.sub.10 alkoxy, C.sub.1 -C.sub.10 alkylthio, C.sub.2 -C.sub.6 alkynoxy, C.sub.2 -C.sub.5 carbalkoxy, phenyl, phenoxy, (C.sub.1 -C.sub.3 alkoxy)phenyl, benzyl and benzyloxy, all optionally substituted with up to two halogen atoms.
