The present invention provided a pyrimidinyl oxyalkane-acidamide derivatives and a fungicide for agri-horticultural of formula [I], in which R1 is hydrogen atom, C1-6 alkyl group, C3-6 cycloalkyl group or the like, R2 is C1-6 alkyl group, C1-4 haloalkyl group or the like, R3 is hydrogen, C1-6 alkyl group, hologen atoms or the like, R4 is hydrogen, C1-6 alkyl group or the like, Q is cyano group or C1-6 alkoxycarbonyl group or the like, A is oxygen atom or sulfur atom. The fungicide for agri-horticultural has a high prevention effect for the blast of rice plant, and comparative to the known compounds, they are exhibited an excellent of prevention effect, however, the characterized in that they are not pharmaceutically harmful to the crops, and having an excellent in residual effect and resistance to rain. |
