Abstract
Abstract The soil lives of many herbicides may be extended combining them with various O-phenylcarbamates having one or two cycloalkyl groups attached to the carbamic nitrogen atom. An exemplary composition is a mixture of isopropyl N-(3-chlorophenyl)carbamate and 4-chlorophenyl N-cyclohexylcarbamate.
