A 3,4,5,6-tetrahydrophthalamide derivative and a 3,4,5,6-tetrahydroisophthalimide derivative, both having an excellent efficay as the active ingredient of a herbicide, and an industrial process for efficiently producing these higher-performance, herbicidally active compounds. A tetrahydrophthalamide derivative represented by general formula (I) is produced by the reaction of a tetrahydrophthalimide derivative, prepared by the reaction of a halogenated 5-cycloalkyloxyaniline derivative with 3,4,5,6-tetrahydrophthalic anhydride, or of the tetrahydroisophthalimide derivative of the invention with various amines. These tetrahydrophthalamide and tetrahydroisophthalimide derivatives have an excellent herbicidal effect in the treatment of lowland and upland soils and foliage treatment. The tetrahydroisophthalimide derivative is useful also as an intermediate for producing the tetrahydrophthalamide derivative and the like.
