| abstract |
The present invention provides an amino-acid amide derivative represented by the formula: (wherein R1 represents a lower alkyl group (optionally having at least one same or different substituent of a halogen atom), R2 represents an ethyl group, R3 represents a hydrogen atom, R4 represents a hydrogen atom, R5, R6, and R7 independently represent a hydrogen atom or a lower alkyl group, R8 represents a hydrogen atom, Z1 and Z2 independently represent an oxygen atom or a sulfur atom, Z3 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. |
