## Abstract

Described herein are fungicidal compositions and methods of controlling and/or suppressing phytopathogenic fungi and fungus-like pathogens and maintaining crop health. Particularly described are fungicidal compositions and methods of controlling the phytopathogenic fungi and the Aphanomyces fungus-like pathogen and maintaining crop health in crops susceptible to infection.

## Claims

### Claim 1

A method of controlling the growth of Aphanomyces sp. in crop plants, the said method comprising:
contacting or applying to foliage, a seed, or a locus of the crop plants an effective amount of a fungicidal combination comprising:
(a) ipconazole,
(b) metalaxyl or a salt thereof, and
(c) carboxin,
wherein the ipconazole, metalaxyl and carboxin are admixed in a weight ratio of (1-80):(1-80):(1-80), respectively, and
wherein the ipconazole, metalaxyl and carboxin are the only fungicides applied.

### Claim 2 (depends on 1)

The method of claim 1, wherein the crop plant is one or more of peas, beans, lentils, and legume crops.

### Claim 3 (depends on 1)

The method of claim 1, wherein the fungicidal combination is a liquid applied at a rate ranging from 200 ml/100 kg to 600 ml/100 kg to seed of the crop plants.

### Claim 4 (depends on 1)

The method of claim 1, wherein the ipconazole, metalaxyl and carboxin are in the form of a liquid composition, and the delivery rate of ipconazole to seed of the crop plants is in the range of 0.5 g a.i./100 kg to 3 g a.i./100 kg; wherein the delivery rate of metalaxyl to seed of the crop plants is in the range of 4 g a.i./100 kg to 8 g a.i./100 kg, and wherein the delivery rate of carboxin to seed of the crop plants is in the range of 50 g a.i./100 kg to 70 g a.i./100 kg.

### Claim 5

A method of improving plant health in crop plants susceptible to Aphanomyces sp. comprising:
contacting or applying to foliage, a seed, or a locus of the crop plants an effective amount of a fungicidal combination comprising:
(a) ipconazole,
(b) metalaxyl or a salt thereof, and
(c) carboxin,
wherein the ipconazole, metalaxyl and carboxin are admixed in a weight ratio of (1-80):(1-80):(1-80), respectively,
wherein the ipconazole, metalaxyl and carboxin are the only fungicides applied; and
wherein the effective amount of the fungicidal combination increases crop yield of legumes in Aphanomyces sp. infested soils.

### Claim 6 (depends on 5)

The method of claim 5, wherein the crop plant is one or more of peas, beans, lentils, and legume crops.

### Claim 7 (depends on 5)

The method of claim 5, wherein the fungicidal combination is a liquid applied at a rate ranging from 200 ml/100 kg to 600 ml/100 kg to seed of the crop plants.

### Claim 8 (depends on 5)

The method of claim 5, wherein the ipconazole, metalaxyl and carboxin are in the form of a liquid composition, and the delivery rate of ipconazole to seed of the crop plants is in the range of 0.5 g a.i./100 kg to 3 g a.i./100 kg; wherein the delivery rate of metalaxyl to seed of the crop plants is in the range of 4 g a.i./100 kg to 8 g a.i./100 kg, and wherein the delivery rate of carboxin to seed of the crop plants is in the range of 50 g a.i./100 kg to 70 g a.i./100 kg.

### Claim 9

A method of controlling the growth of Aphanomyces sp. in legumes, the method comprising:
contacting or applying to foliage, a seed, or a locus of the legumes an effective amount of a fungicidal combination comprising:
(a) ipconazole,
(b) metalaxyl or a salt thereof, and
(c) carboxin,
wherein the ipconazole, metalaxyl and carboxin are admixed in a weight ratio of (1-5):(1-15):(20-40), respectively,
wherein the ipconazole, metalaxyl and carboxin are the only fungicides applied; and
wherein the effective amount of the fungicidal combination reduces Aphanomyces sp. growth.
