Abstract:
Herbicidally active thiocarbamates are employed in combination with organophosphorothioates, the latter in sufficient qualtity to prevent soil degradation of the former. As a result, the herbicidal effectiveness of the thiocarbamate is significantly enhanced and prolonged, rendering a single application of the herbicide effective over a longer period of time.
Abstract:
Herbicidally active thiolcarbamates are employed in combination with certain substituted carbamates having the formula in which R 4 and R 5 are each methyl, R 4 and R 5 conjointly form C 1 -C 4 alkylenedioxy, R 4 is -CF 3 and R 5 is hydrogen, or R 4 is -CH 2 Br and R 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.
