## Abstract

An agricultural or horticultural chemical according to the present invention is an agricultural or horticultural chemical containing a plurality of active ingredients, the agricultural or horticultural chemical comprises, as one of the active ingredients, an azole derivative represented by general formula (I) below, and can be used as a plant disease controlling agent that can reduce the content of an active ingredient: wherein, R1 represents an alkyl group having from 1 to 6 carbons, R2 represents a hydrogen atom, an alkyl group having from 1 to 3 carbons, an alkenyl group or an alkynyl group having from 2 to 3 carbons, A represents a nitrogen atom or a methine group, Y1 represents a halogen atom, and n represents either 0 or 1.

## Claims

### Claim 1

A fungicide containing a plurality of active ingredients in an effective amount, the fungicide comprising: as one of active ingredients, an azole derivative represented by general formula (I) below; and, as another one of the active ingredients, a compound having a ubiquinol reductase inhibitory capacity:
wherein, R1 represents an alkyl group having from 1 to 6 carbons, R2 represents a hydrogen atom, an alkyl group having from 1 to 3 carbons, an alkenyl group having from 2 to 3 carbons or an alkynyl group having from 2 to 3 carbons, A represents a nitrogen atom, Y1 represents a halogen atom, and n represents either 0 or 1.

### Claim 2 (depends on 1)

The fungicide according to claim 1, wherein the compound having a ubiquinol reductase inhibitory capacity is at least any one of pyraclostrobin, azoxystrobin, kresoxim-methyl, trifloxystrobin, fluoxastrobin, picoxystrobin, and dimoxystrobin.

### Claim 3 (depends on 1)

The fungicide according to claim 1, wherein the azole derivative is an azole derivative represented by general formula (Ia) below:
wherein, Y2 represents a chlorine atom, a fluorine atom or a hydrogen atom.

### Claim 4

A product for controlling plant diseases separately comprising, as combination preparations by which a plurality of active ingredients, in an effective amount, are mixed for use: an azole derivative represented by general formula (I) below; and a compound having a ubiquinol reductase inhibitory capacity:
wherein, R1 represents an alkyl group having from 1 to 6 carbons, R2 represents a hydrogen atom, an alkyl group having from 1 to 3 carbons, an alkenyl group having from 2 to 3 carbons or an alkynyl group having from 2 to 3 carbons, A represents a nitrogen atom, Y1 represents a halogen atom, and n represents either 0 or 1.
