Pyrimidinyloxyalkanamide derivatives and herbicide composition

Abstract

A pirimidinyloxyalkanamide derivative of Formula 1: ##STR1## wherein R.sub.1 represents a hydrogen atom, a halogen atom, a lower alkyl group, a lower alkylthio group, a lower alkenylthio group, a lower alkynylthio group, a halogenated lower alkenylthio group, a cycloalkylthio group, an aroxyalkylthio group, a lower alkoxyl group, an amino group, a methanesulfonyl group, a trifluoromethyl group, an anilino group which may be substituted with a halogen atom or a benzylthio group which may be substituted with a halogen atom; R.sub.2 represents a hydrogen atom, a halogen atom, a lower alkyl group, a trifluoromethyl group, an amino group, a lower alkoxy group or a lower alkylthio group; R.sub.3 represents an ethyl group or an n-propyl group; and R.sub.4 represents a cyclohexyl group, a thienyl group, a pyridyl group, a furyl group or a ##STR2## group wherein X and Y may be the same or different and each represent a hydrogen atom, a lower alkyl group, a trifluoromethyl group, a lower alkoxyl group or a halogen atom, and a herbicide composition comprising the same as an active ingredient.
