An N-(3-chloro-4-isopropylphenyl)carboxamide derivative represented by the general formula
wherein R represents a 1-methylbutyl, 1-methylcyclopropyl or cyclopropyl group. This derivative is useful as a selective herbicide, and can be pro- duced by reacting 3-chloro-4-isopropylaniline with a carboxylic acid halide derivative of the general formula
wherein R is as defined above and X represents halogen, or with a carboxylic acid anhydride of the general formula
wherein R is as defined above.
