Abstract: It is to provide a novel fungicide having high controlling effects on plant diseases particularly on wheat powdery mildew and cucumber gray mold, without ill effects on crops. A carbamate derivative represented by the general formula [I] {wherein X is a halogen atom, a C1-C6 alkyl group or the like, n is 0 or an integer of from 1 to 4, R1 is a C1-C6 alkyl group, R2 is a hydrogen atom, a C1-C6 alkyl group or the like, R3 is a hydrogen atom or a C1-C6 alkyl group, G is an oxygen atom, a sulfur atom or the like, Y is a hydrogen atom, a C1-C10 alkyl group, C2-C10 alkenyl group or the like, and Q is a hydrogen atom, a C1-C6 haloalkyl group, a phenyl group or the like} and an agricultural/horticultural fungicide containing the same as the active ingredient.

Abstract: A phenylacetylene derivative represented by the formula [I]: {wherein X is a halogen atom, a C1-C6 alkyl group, a C2-C6 alkoxy group, a C2-C6 haloalkyl group, etc., n is 0 or an integer of from 1 to 4, R1 is a C1-C6 alkyl group, R2 is a hydrogen atom, a C1-C6 alkyl group, a C2-C6 alkynyl group, a C2-C6 alkynyl group, a C1-C6 alkoxy group, etc., A is a C1-C6 alkylene group which may be branched, G is an oxygen atom, a sulfur atom or a —NR3— group; R3 is a hydrogen atom or a C1-C6 alkyl group, and Y is a hydrogen atom, a C1-C10 alkyl group, said group may be substituted by a halogen atom, a hydroxyl group or a C1-C6 alkoxy group], a C2-C6 alkenyl group, etc.; and an agricultural/horticultural fungicide containing the same as the active ingredient.
