Method of controlling weeds in warm season turfgrass
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.
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.
2. The method of claim 1 , wherein the spraying is to the weed.
3. The method of claim 2 , wherein the turfgrass management is in a golf-course.
4. The method of claim 3 , wherein fairways and greens are sprayed with different rates of pinoxaden.
5. The method of claim 2 , wherein the turfgrass management is in a sod farm.
6. The method of claim 2 , wherein the turfgrass management is in a lawn.
7. The method of claim 2 , wherein the turfgrass management is in a public park.
8. The method of claim 1 , wherein quality of the turfgrass is improved.
9. The method of claim 1 , wherein visual quality of the turfgrass is improved.
10. The method of claim 1 , wherein functional quality of the turfgrass is improved.
11. The method of claim 1 , further comprising:
providing the composition as a concentrate; and
diluting, dispersing, or dissolving the concentrate.
12. The method of claim 11 , wherein the concentrate is an emulsion concentrate (EC).
13. The method of claim 11 , wherein the concentrate contains an adjuvant.
14. 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.
15. The method of claim 14 , wherein the tank-mixing is with the one or more adjuvants.
16. The method of claim 15 , further comprising tank-mixing with a safener.
17. The method of claim 16 , wherein the safener is cloquintocet-mexyl.
18. The method of claim 1 , wherein the composition is a ready to use composition.
19. The method of claim 2 , wherein the turfgrass is bermudagrass.
20. The method of claim 19 , wherein the pinoxaden is sprayed at 70 to 140 g/ha.
21. The method of claim 20 , wherein the weed is Paspalum notatum.
22. The method of claim 20 , wherein the weed is Digitaria sanguinalis.
23. The method of claim 20 , wherein the weed is Axonopus compressus.
24. The method of claim 20 , wherein the weed is Panicum repens.
25. The method of claim 20 , wherein the weed is dallisgrass.
26. The method of claim 20 , wherein the weed is tropical signalgrass.
