PCT No. PCT/JP95/00981 Sec. 371 Date Feb. 3, 1997 Sec. 102(e) Date Feb. 3, 1997 PCT Filed May 23, 1995 PCT Pub. No. WO96/04252 PCT Pub. Date Feb. 15, 1996The present invention provides an amino-acid amide derivative represented by the formula: <IMAGE> (wherein R1 represents a C1 DIFFERENCE C6 alkyl group, a C3 DIFFERENCE C8 cycloalkyl group, or a phenyl group, R2 represents a hydrogen atom or a methyl group, X represents a halogen atom, a methyl group, a methoxy group, Y represents a C1 DIFFERENCE C6 alkyl group, A represents an oxygen atom, or a sulfur atom, and n represents 0 or an integer from 1 to 3), an agricultural or horticultural fungicide including an effective amount of the same, and a method for killing agriculturally or horticulturally harmful fungi which comprises a step of using a fungicidally effective amount of the amino-acid amide derivative. The present invention provides the amino-acid amide derivatives, which exhibit superior control of plant diseases such as late blight and downy mildew, and which are not harmful chemicals.
