<p>Herbicidally active thiolcarbamates are employed in combination with certain substituted carbamates having the formula

<UnorderedLists id="ula01" listStyle="none"><ListItem>R<Sup>4</Sup> and R<Sup>5</Sup> are each methyl,</ListItem><ListItem>R<Sup>4</Sup> and R<Sup>5</Sup> conjointly form C<Sub>1</Sub>-C<Sub>4</Sub> alkylenedioxy,</ListItem><ListItem>R<Sup>4</Sup> is -CF<Sub>3</Sub> and R<Sup>5</Sup> is hydrogen, or</ListItem><ListItem>R<Sup>4</Sup> is -CH<Sub>2</Sub>Br and R<Sup>5</Sup> is hydrogen.</ListItem></UnorderedLists>
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.</p> |
