ABSTRACT:
Herbicidally active thiolcarbamates are employed in combination with certain organophosphorus compounds having the formula ##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 alkoxy and C.sub.2 -C.sub.4 alkynylthio; R.sup.6 is C.sub.1 -C.sub.4 alkylene; R.sup.7 is selected from the group consisting of methyl and phenyl, X is oxygen or sulfur; Y is oxygen or sulfur; m is zero or one; 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.
