Herbicide Composition of Life on Earth

摘要

Herbicidally active thiolcarbamates are employed in combination with certain substituted carbamates having the formula IMAGE in which R4 and R5 are each methyl, R4 and R5 conjointly form C1-C4 alkylenedioxy, R4 is -CF3 and R5 is hydrogen, or R4 is -CH2Br and R5 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.
