Abstract
Herbicidally active thiolcarbamates are employed in combination with certain organophosphorous compounds having the formula ##STR1## in which R.sup.4 is selected from the group consisting of C.sub.1 -C.sub.4 alkyl, C.sub.1 -C.sub.4 alkoxy and C.sub.1 -C.sub.4 alkylthio; R.sup.5 is selected from the group consisting of C.sub.1 -C.sub.4 alkoxy and C.sub.1 -C.sub.4 alkylthio; R.sub.6 is selected from the group consisting of C.sub.2 -C.sub.6 alkylene and C.sub.2 -C.sub.6 alkenylene; R.sup.7 is selected from the group consisting of hydrogen, phenyl, C.sub.1 -C.sub.4 alkyl and C.sub.2 -C.sub.4 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.
