The present invention provides the compounds represented by the general formula(I):[wherein X is a halogen atom or an (C-C) alkyl groupwhich may be substituted with a halogen atom(s)； Y is a hydrogen or halogen atom,or a cyano, a (C1-C3) alkyl or (C-C) alkoxy group； R is ahydrogen or halogen atom, a cyano group, or a (C1-C6) alkyl , (C2-C6) alkenyl group,(C2-C6) alkynyl, (C1-C6) alkoxy, (C2-C6) alkenyloxy, (C2-C6) alkynyloxy,(C1-C6) alkylthio, (C-C) alkylsulfinyl or (C1-C6) alkylsulfonylgroup which may be substituted with a halogen atom(s), a (C1-C6) alkoxycarbonylgroup, a (C-C) alkoxyimino (C1-C3) alkyl group, a tri(C1-C10) alkylsilyl group, or a phenyl,phenoxy, pyridyloxy or pyrimidyloxygroup which may be substituted with a substituent (s) ； n is an integer of 1 to 5 ], which compounds cause reduced loads of deleterious, harmful effects to theearth environment, and exhibit a widened controlling spectrum at lowered chemicalapplication rates, thereby finding useful application as a plant disease controllingagent for agricultural and horticultural uses.
