Abstract: Herbicidally active thiocarbamates are employed in combination with certain unsaturated aryl sulfides, sulfoxides or sulfones having the formula ##STR1## in which R.sup.4 is hydrogen, halogen, C.sub.1 -C.sub.6 alkyl or C.sub.1 -C.sub.6 alkoxy; R.sup.5 is C.sub.2 -C.sub.6 haloalkenyl or C.sub.2 -C.sub.6 alkynyl; and n equals 0 or 2. In a typical application, the unsaturated aryl sulfide, sulfoxide or sulfone is included in sufficient quantity to lessen the rate of soil degradation of the thiocarbamate. 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.
