ABSTRACT:
Herbicidally active thiolcarbamates are employed in combination with certain N-methylcarbamoyloxy benzaldehyde imines having the formula ##STR1## in which R.sup.4 is selected from the group consisting of chlorophenyl, chlorophenylthiomethylphenyl, acetoxy, and ##STR2## where R.sup.5 is selected from the group consisting of phenyl, pyridyl, and cyanomethyl, and n is zero or one.
In a typical application, the imine 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.
