PCT No. PCT/JP97/03945 Sec. 371 Date Apr. 30, 1999 Sec. 102(e) Date Apr. 30, 1999 PCT Filed Oct. 30, 1997 PCT Pub. No. WO98/18766 PCT Pub. Date May 7, 1998The present invention provides a pyrimidinyloxyalkanamide derivative represented by Formula (I): (wherein R1 represents a hydrogen atom, a C1-C6 alkyl group, a C3-C6 cycloalkyl group, or the like, R2 represents a C1-C6 alkyl group, a C1-C4 haloalkyl group, or the like, R3 represents a hydrogen atom, a C1-C6 alkyl group, a halogen atom, or the like, R4 represents a hydrogen atom, a C1-C6 alkyl group, or the like, Q represents a cyano group, a C1-C6 alkoxycarbonyl group, or the like, and A represents an oxygen atom or a sulfur atom) and a novel agricultural or horticultural fungicide including the same as an active ingredient. The agricultural or horticultural fungicides according to the present invention have excellent controlling effects with regard to rice blast, which are apparently excellent controlling effects as compared with the known compounds. In addition, the agricultural or horticultural fungicides of the present invention also exhibit excellent residual activity, as well as persistence after rain without any negative effects on the subject plants.
