The present invention provides a novel nitrogen-containing heterocyclic compound represented by formula (I) and its salt or N-oxide compound, and an agricultural and horticultural fungicide containing at least one selected from them as an active ingredient. In formula (I), R represents a group represented by CR 1 R 2 R 3 or a cyano group. R 1 to R 3 each independently represent a hydrogen atom, an unsubstituted or substituted C1-8 alkyl group, an unsubstituted or substituted hydroxyl group, and the like. R 4 or R 5 represents a halo group and the like. Y or Z represents a carbon atom or the like, and A or D represents a benzene ring or the like. X represents an oxygen atom, a nitrogen atom, or the like. Formula (I) |
