Abstract

This fungicide for agricultural and horticultural use includes a compound represented by formula (I) (in the formula, X represents a halogen group, or the like; n represents any integer of 0 to 4; when n is 2 or more, X may be the same or different; L represents a single bond or a substituted or unsubstituted C1-6 alkylene group; Q is a group represented by formula (Q-1) or formula (Q-2) (in the formulae, * represents a binding site; Y1 is N or CR1; Y2 is N or CR2; Y3 is N or CR3; Y4 is N or CR4, at least two of Y1 to Y4 are not nitrogen atoms; R1, R2, R3, and R4, each independently represent a hydrogen atom, a substituted or unsubstituted C1-6 alkyl group, or the like; R represents a substituted or unsubstituted C1-6 alkyl group or the like; G represents a substituted or unsubstituted C1-6 alkylene group; T represents a substituted or unsubstituted C1-6 alkylene group; Y5 is N or CH)) or a salt thereof.

First claim

The invention claimed is:

1. A compound of formula (I) or a salt thereof:

wherein, in the formula (I),
X represents a substituted or unsubstituted C1-6 alkyl group, a substituted or unsubstituted C1-6 alkoxy group or a halogeno group,
n represents a chemically acceptable number of X, and is an integer of 0 to 4, and, when n is 2 or more, X is identical to or different from each other,
L represents a single bond, or a substituted or unsubstituted C1-6 alkylene group,
Q represents a group of formula (Q-1) or formula (Q-2):

in the formula (Q-1) and the formula (Q-2), * represents a bonding position,
in the formula (Q-1),
Y 1 represents a nitrogen atom or CR 1 ,
Y 2 represents a nitrogen atom or CR 2 ,
Y 3 represents a nitrogen atom or CR 3 ,
Y 4 represents a nitrogen atom or CR 4 ,
provided that, at least two of Y 1 to Y 4 do not represent nitrogen atoms,
R 1 , R 2 , R 3 , and R 4 each independently represent a hydrogen atom, a substituted or unsubstituted C1-6 alkyl group, a hydroxyl group, a substituted or unsubstituted C1-6 alkoxy group, a substituted or unsubstituted C1-6 alkoxycarbonyl group, a substituted or unsubstituted C1-6 alkylcarbonyloxy group, a substituted or unsubstituted C1-6 alkylthio group, a substituted or unsubstituted alkylsulfinyl group, a substituted or unsubstituted alkylsulfonyl group, a substituted or unsubstituted C6-10 aryl group, a substituted or unsubstituted 5- to 6-membered heterocyclyl group, a substituted or unsubstituted C6-10 aryloxy group, a substituted or unsubstituted amino group, a substituted or unsubstituted aminocarbonyl group, a halogeno group or a cyano group,
at least one of R 1 , R 2 , R 3 , and R 4 represents a substituted C1-6 alkoxy group, and a substituent on the substituted C1-6 alkoxy group is a halogeno group, a C2-6 alkenyl group, a C1-6 alkoxy group, a C1-6 alkylthio group, a C1-6 alkylsulfinyl group, a C1-6 alkylsulfonyl group, a substituted or unsubstituted C1-6 alkoxyimino group, a 5- to 6-membered saturated heterocyclyloxyimino group, a C6-10 aryloxyimino group, a cyano group or an aminothiocarbonyl group,
in the formula (Q-2),
R represents a hydrogen atom, a 5- to 6-membered saturated heterocyclyl group or a substituted or unsubstituted C1-6 alkyl group,
G represents a substituted or unsubstituted C1-6 alkylene group,
T represents a substituted or unsubstituted C1-6 alkylene group, and
Y 5 represents a nitrogen atom or CH.

2. The compound or the salt thereof according to claim 1 , wherein the formula (I) is formula (II):

in the formula (II), X, n and L represent the same groups as those in the formula (I), and Y 1 to Y 4 represent the same groups as those in the formula (Q-1).

3. The compound or the salt thereof according to claim 1 , wherein the formula (I) is formula (III):

in the formula (III), X, n and L represent the same groups as those in the formula (I), and R, G, T and Y 5 represent the same groups as those in the formula (Q-2).

4. An agricultural or horticultural fungicide comprising, as an active ingredient thereof, at least one selected from the group consisting of a compound and a salt thereof of claim 1 .
