## Abstract

The present invention relates to a method for controlling dallisgrass or tropical signalgrass in warm-season turfgrass, comprising applying to the warm-season turfgrass or to the locus of the warm-season turfgrass an effective rate of pinoxaden.

## Claims

### Claim 1

A method of turfgrass management in a turfgrass, comprising:
spraying a weed, the turfgrass, or the locus of the turfgrass with a composition comprising pinoxaden;
wherein:
the turfgrass is a warm-season turfgrass;
the pinoxaden is present in an amount effective in controlling the weed;
the weed is selectively controlled over the warm-season turfgrass; and
the weed is selected from tropical signalgrass, tropical carpetgrass, large crabgrass, bahiagrass, torpedograss, bull Paspalum, thin Paspalum, and dallisgrass.

### Claim 2 (depends on 1)

The method of claim 1, wherein the spraying is to the weed.

### Claim 3 (depends on 2)

The method of claim 2, wherein the turfgrass management is in a golf-course.

### Claim 4 (depends on 3)

The method of claim 3, wherein fairways and greens are sprayed with different rates of pinoxaden.

### Claim 5 (depends on 2)

The method of claim 2, wherein the turfgrass management is in a sod farm.

### Claim 6 (depends on 2)

The method of claim 2, wherein the turfgrass management is in a lawn.

### Claim 7 (depends on 2)

The method of claim 2, wherein the turfgrass management is in a public park.

### Claim 8 (depends on 1)

The method of claim 1, wherein quality of the turfgrass is improved.

### Claim 9 (depends on 1)

The method of claim 1, wherein visual quality of the turfgrass is improved.

### Claim 10 (depends on 1)

The method of claim 1, wherein functional quality of the turfgrass is improved.

### Claim 11 (depends on 1)

The method of claim 1, further comprising:
providing the composition as a concentrate; and
diluting, dispersing, or dissolving the concentrate.

### Claim 12 (depends on 11)

The method of claim 11, wherein the concentrate is an emulsion concentrate (EC).

### Claim 13 (depends on 11)

The method of claim 11, wherein the concentrate contains an adjuvant.

### Claim 14 (depends on 12)

The method of claim 12, further comprising tank-mixing the concentrate with one or more active ingredients that are not pinoxaden, one or more surfactants, or one or more adjuvants.

### Claim 15 (depends on 14)

The method of claim 14, wherein the tank-mixing is with the one or more adjuvants.

### Claim 16 (depends on 15)

The method of claim 15, further comprising tank-mixing with a safener.

### Claim 17 (depends on 16)

The method of claim 16, wherein the safener is cloquintocet-mexyl.

### Claim 18 (depends on 1)

The method of claim 1, wherein the composition is a ready to use composition.

### Claim 19 (depends on 2)

The method of claim 2, wherein the turfgrass is bermudagrass.

### Claim 20 (depends on 19)

The method of claim 19, wherein the pinoxaden is sprayed at 70 to 140 g/ha.

### Claim 21 (depends on 20)

The method of claim 20, wherein the weed is Paspalum notatum.

### Claim 22 (depends on 20)

The method of claim 20, wherein the weed is Digitaria sanguinalis.

### Claim 23 (depends on 20)

The method of claim 20, wherein the weed is Axonopus compressus.

### Claim 24 (depends on 20)

The method of claim 20, wherein the weed is Panicum repens.

### Claim 25 (depends on 20)

The method of claim 20, wherein the weed is dallisgrass.

### Claim 26 (depends on 20)

The method of claim 20, wherein the weed is tropical signalgrass.
