An N-2-(hetero)arylethylcarboxamide derivative represented by the formula (I) wherein Rand Rare each independently a hydrogen atom etc., Rand Rare each independently a hydrogen atom etc., each Y is independently a halogen atom; a (C-C)alkyl group optionally substituted by halogen atom(s) etc., n is an integer of 1 to 5, A is a specific substituted cyclic group, E is C&#x2014;H; C&#x2014;Y (Y is as defined above); or a nitrogen atom, a salt thereof, and a pest controlling agent containing the derivative or salt as an active ingredient show superior performance as compared to the prior art technique, and are is useful particularly as plant disease controlling agents or nematocides having a broad control spectrum at a low dose.

The present invention provides the compounds represented by the general formula (I): [wherein X is a halogen atom or an (C-C)alkyl group which may be substituted with a halogen atom(s); Y is a hydrogen or halogen atom, or a cyano, a (C-C)alkyl or (C-C)alkoxy group; R is a hydrogen or halogen atom, a cyano group, or a (C-C)alkyl, (C-C)alkenyl group, (C-C)alkynyl, (C-C)alkoxy, (C-C)alkenyloxy, (C-C)alkynyloxy, (C-C)alkylthio, (C-C)alkylsulfinyl or (C-C)alkylsulfonyl group which may be substituted with a halogen atom(s), a (C-C)alkoxycarbonyl group, a (C-C)alkoxyimino(C-C)alkyl group, a tri(C-C)alkylsilyl group, or a phenyl, phenoxy, pyridyloxy or pyrimidyloxy group 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 the earth environment, and exhibit a widened controlling spectrum at lowered chemical application rates, thereby finding useful application as a plant disease controlling agent for agricultural and horticultural uses.
