The present invention provides an amino-acid amide derivative represented by the formula: ##STR1## (wherein R.sup.1 represents a lower alkyl group (optionally having at least one same or different substituent of a halogen atom), R.sup.2 represents an ethyl group, R.sup.3 represents a hydrogen atom, R.sup.4 represents a hydrogen atom, R.sup.5, R.sup.6, and R.sup.7 independently represent a hydrogen atom or a lower alkyl group, R.sup.8 represents a hydrogen atom, Z.sup.1 and Z.sup.2 independently represent an oxygen atom or a sulfur atom, Z.sup.3 represents an oxygen atom or a sulfur atom, Q represents a phenyl group, m represents an integer from 0 to 2, and n represents 0 or 1), and an agricultural or horticultural fungicide including an effective amount of the same. The amino-acid amide derivatives exhibit a superior control of plant diseases, particularly downy mildew and late blight, and are not harmful to plants.
