## Abstract

The disclosure provides methods for reducing fungal infestation to a crop or plant by applying a composition including propamocarb and Bacillus firmus to a crop or plant. Methods of reducing yellow spot infestation to a plant or crop are also described herein. The disclosure also provides for compositions and methods of improving turfgrass and/or ornamental grass quality.

## Claims

### Claim 1

A composition comprising:
a) propamocarb; and
b) Bacillus firmus
wherein the propamocarb and Bacillus firmus in said composition are present in amounts that synergistically reduce or control yellow spot in a plant when treating soil, a seed, a plant, and/or a plant part with a composition comprising a) and b).

### Claim 2 (depends on 1)

A kit comprising a composition of claim 1.

### Claim 3 (depends on 1)

The composition of claim 1, wherein component (a) is propamocarb-HCl.

### Claim 4 (depends on 1)

The composition of claim 1, wherein the weight ratio of propamocarb to Bacillus firmus is 0.75:1-1:12.

### Claim 5 (depends on 1)

A method of reducing or controlling yellow spot in a plant or crop comprising treating soil, a seed, a plant, and/or a plant part with a composition according to claim 1.

### Claim 6 (depends on 5)

The method of claim 5, wherein component (a) is propamocarb-HCl.

### Claim 7 (depends on 5)

The method of claim 5, comprising treating soil, a seed, a plant, and/or a plant part with a composition comprising:
a) propamocarb-HCl in an application amount from about 2 to about 4.5 fl. oz/1000 ft2; and
b) 5% Bacillus firmus in an application amount from about 6 to about 24 oz/1000 ft2.

### Claim 8 (depends on 5)

The method of claim 5, comprising treating soil, a seed, a plant, and/or a plant part with a composition comprising:
a) propamocarb-HCl in an application amount of about 2 fl. oz/1000 ft2; and
b) 5% Bacillus firmus in an application amount of about 12.9 oz/1000 ft2.

### Claim 9 (depends on 5)

The method according to claim 5, wherein said composition is applied as a foliar treatment.

### Claim 10 (depends on 5)

The method according to claim 5, wherein said composition is applied as a treatment to one or more turfgrass leaves.

### Claim 11 (depends on 1)

A method of improving turfgrass quality comprising treating soil, a seed, a plant, and/or a plant part with a composition according to claim 1.

### Claim 12 (depends on 11)

The method of claim 11, comprising treating soil, a seed, a plant, and/or a plant part with a composition comprising:
a) propamocarb-HCl in an application amount from about 2 to about 4.5 fl. oz/1000 ft2; and
b) 5% Bacillus firmus in an application amount from about 6 to about 24 oz/1000 ft2.

### Claim 13 (depends on 11)

The method of claim 11, comprising treating soil, a seed, a plant, and/or a plant part with a composition comprising:
a) propamocarb-HCl in an application amount of about 2 fl. oz/1000 ft2; and
b) 5% Bacillus firmus in an application amount of about 12.9 oz/1000 ft2.

### Claim 14 (depends on 11)

The method according to claim 11, wherein said composition is applied as a foliar treatment.

### Claim 15 (depends on 1)

A method of reducing or controlling yellow spot in a plant or crop comprising treating soil, a seed, a plant, and/or a plant part with a composition of claim 1 that consists of:
a) propamocarb; and
b) Bacillus firmus.

### Claim 16

A composition consisting essentially of
a) propamocarb; and
b) Bacillus firmus,
wherein the propamocarb and Bacillus firmus in said composition are present in amounts that synergistically reduce or control yellow spot in a plant when treating soil, a seed, a plant, and/or a plant part with a composition comprising a) and b).
