  • Patent number: 4299616
    Abstract: Herbicidally active thiolcarbamates are employed in combination with certain substituted carbamates having the formula ##STR1## in which R.sup.4 and R.sup.5 are each methyl,R.sup.4 and R.sup.5 conjointly form C.sub.1 --C.sub.4 alkylenedioxy,R.sup.4 is --CF.sub.3 and R.sup.5 is hydrogen, orR.sup.4 is --CH.sub.2 Br and R.sup.5 is hydrogen.In a typical application, the carbamate 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.
