The present invention provides a novel alkanoic acid amide derivative of the formula, ##STR1## (wherein R.sup.1 is a hydrogen atom, an alkyl group or an alkoxyalkoxy group, R.sup.2 is a group of --SO.sub.2 R or a hydroxyl group, R.sup.5 is an alkyl group, R.sup.3 is an alkyl group, a cycloalkyl group, a cycloalkenyl group or a phenyl group, R.sup.4 is a hydrogen atom or an alkyl group, X and Y may be the same or different and are an alkoxy group, an alkylamino group or a dialkylamino group, and Z is a methine group or a nitrogen atom) and its salt, a process for preparing the same and a herbicidal composition containing the same as an effective ingredient. This compound kills annual and perennial weeds grown in paddy fields and upland fields at a small dose, and is safe to a useful crop plant.
