摘要

An amino acid amide derivative represented by general formula (I), anagrohorticultural fungicide containing the derivative as the activeingredient, and a fungicidal method using the fungicide against destructivefungi. In formula (I), R1 represents C1-C6 alkyl, C3-C8 cycloalkyl or phenyl;R2 represents hydrogen or methyl; X represents halogen, methyl or methoxy; Yrepresents C1-C6 alkyl; A represents oxygen or sulfur; and n represents aninteger of 0, 1 to 3. The derivative has a potent control effect againstdisease damages, particularly plague and downy mildew.
