## Abstract

The present invention relates to novel active compound combinations comprising the known fungicidally active compounds N-[2-(1,3-dimethylbutyl)phenyl]-5-fluoro-1,3-dimethyl-1H-pyrazole-4-carboxamide, metalaxyl and strobilurin (3), which are highly suitable for controlling unwanted phytopathogenic fungi. Moreover, the invention relates to a method for the curative or preventive treatment of phytopathogenic fungi on plants or useful plants, in particular to the treatment of seed, for example seed of cereals, and not least to the treated seed itself.

## Claims

### Claim 1

An active compound combination, comprising
(1) N-[2-(1,3-dimethylbutyl)phenyl]-5-fluoro-1,3-dimethyl-1H-pyrazole-4-carboxamide and/or a salt thereof, and
(2) metalaxyl, and
(3) trifloxystrobin, and/or a salt thereof,
wherein 0.005-500 parts by weight of N-[2-(1,3-dimethylbutyl)phenyl]-5-fluoro-1,3-dimethyl-1H-pyrazole-4-carboxamide (1) and 0.005-500 parts by weight of metalaxyl (2) are used per part by weight of trifloxystrobin (3).

### Claim 2 (depends on 1)

An active compound combination according to claim 1, which is fungicidally active.

### Claim 3 (depends on 1)

A composition comprising an active compound combination according to claim 1.

### Claim 4 (depends on 3)

A composition according to claim 3, further comprising an auxiliary, solvent, carrier, surfactant and/or extender.

### Claim 5 (depends on 3)

A method for controlling phytopathogenic fungi in crop protection or in the protection of materials, comprising applying a composition according to claim 3 to seed, a plant, to fruits of plants and/or to soil on which a plant grows and/or is supposed to grow.

### Claim 6 (depends on 5)

A method according to claim 5, wherein in the treatment of leaves from 0.1 to 10 000 g/ha of the composition are used, in the treatment of seed from 0.01 to 200 g of the composition per 100 kg of seed are used, and in the soil treatment from 0.1 to 10 000 g/ha of the composition are used.

### Claim 7 (depends on 1)

Seed treated with an active compound combination according to claim 1.

### Claim 8 (depends on 1)

The active compound combination according to claim 1, wherein 0.1-10 parts by weight of N-[2-(1,3-dimethylbutyl)phenyl]-5-fluoro-1,3-dimethyl-1H-pyrazole-4-carboxamide (1) and 0.1-10 parts by weight of metalaxyl (2) are used per part by weight of trifloxystrobin (3).

### Claim 9

A method for controlling phytopathogenic fungi in crop protection or in the protection of materials, comprising applying a composition comprising the active compounds N-[2-(1,3-dimethylbutyl)phenyl]-5-fluoro-1,3-dimethyl-1H-pyrazole-4-carboxamide (1), metalaxyl (2), and trifloxystrobin (3) wherein the active compounds (1), (2) and (3) are applied simultaneously or in succession to seed, to a plant, to leaves, to fruits of plants and/or to soil on which a plant grows and/or is supposed to grow.

### Claim 10 (depends on 9)

A method according to claim 9, wherein seed is treated.

### Claim 11 (depends on 9)

A method according to claim 9, wherein transgenic plants are treated.

### Claim 12 (depends on 9)

A method according to claim 9, wherein the compounds are applied simultaneously.

### Claim 13 (depends on 9)

A method according to claim 9, wherein the actives are applied in succession.
