ABSTRACT:
Herbicidally active thiolcarbamates are employed in combination with certain halogenated allylthioisopropyl N-methylcarbamates having the formula ##STR1## in which R.sup.4, R.sup.5, R.sup.6, R.sup.7, R.sup.8, and R.sup.9 are independently halogen. In a typical application, the N-methylcarbamate is included in sufficient quantity to lessen the rate of soil degradation of the thiolcarbamate. As a result, the herbicidal effectiveness of the thiolcarbamate is enhanced and prolonged, rendering a single application of the herbicide effective over a longer period of time.
