Composition and system for turf maintenance
View Patent ↗The present invention provides an agricultural composition comprising a plant growth regulator and a pigment that provides reduced phytotoxicity as compared to an equivalent application of the plant growth regulator alone. The composition can further include a fungicide. A system for turf management as well as methods for enhancing turf are also provided.
1. An agricultural combination for enhancing turf comprising:
(a) at least one plant growth regulator comprising ethephon, trinexapac ethyl, paclobutrazole, flurprimidol or a combination thereof; and
(b) at least one pigment comprising a phthalocyanine compound; and
at least one fungicide comprising fosetyl aluminum,
wherein the combination provides phytoregulation and reduced phytotoxicity as compared to an equivalent application of the plant growth regulator alone in turf.
2. The agricultural combination of claim 1 , wherein the at least one plant growth regulator is a combination of ethephon and trinexapac ethyl.
3. The agricultural combination of claim 1 , wherein the at least one fungicide further comprises, trifloxystrobin, triadimefon, triticonazole, iprodione or a combination thereof.
4. The agricultural combination of claim 1 , wherein the phthalocyanine compound is Pigment Blue 16, Vat Blue 29, Pigment Blue 15, Heliogen Green GG, Ingrain Blue 14, Ingrain Blue 5, Ingrain Blue 1, Pigment Green 37, Pigment Green 7, or a combination thereof.
5. The agricultural combination of claim 1 , wherein said pigment is present in an amount of between about 1 to about 900 parts by weight of total composition.
6. The agricultural combination of claim 1 , wherein the combination is an aqueous suspension or a wettable powder.
7. A method for enhancing turf quality comprising applying an effective amount of a combination according to claim 1 to the turf.
8. The method of claim 7 , wherein said at least one pigment is present in an approximate amount of about 1 to about 900 parts by weight of the total composition.
9. The method of claim 7 , wherein said combination is applied in an amount of from about 300 to about 800 L/ha.
10. The method of claim 7 , wherein said combination is applied to the turf selected from Bluegrass, Bentgrass, Fescue, Ryegrass, Wheatgrass, Beachgrass, Orchardgrass, Timothy, Smooth Brome, Bermudagrass, Zoysiagrass, St. Augustinegrass, Centipedegrass, Carpetgrass, Bahiagrass, Kikuyugrass, Buffalograss, Blue Grama, and Sideoats Grama.
11. The method of claim 10 , wherein the turf is said Bluegrass, Bentgrass, Fescue, or Ryegrass.
12. A system for turf management comprising a combination according to claim 1 .
13. The agricultural combination of claim 1 , wherein said phthalocyanine compound comprises copper.
14. The agricultural combination of claim 1 , wherein said fungicide consists essentially of fosetyl aluminum.
15. The agricultural combination of claim 1 , wherein said at least one plant growth regulator comprises ethephon.
16. The agricultural combination of claim 1 , wherein said at least one plant growth regulator comprises trinexapac ethyl.
17. The agricultural combination of claim 1 , wherein said at least one plant growth regulator comprises paclobutrazole.
18. The agricultural combination of claim 1 , wherein said at least one plant growth regulator comprises flurprimidol.
19. The agricultural combination of claim 1 , wherein said at least one plant growth regulator comprises ethephon, and wherein said fungicide consists essentially of fosetyl aluminum.
20. The agricultural combination of claim 1 , wherein said at least one plant growth regulator comprises trinexpac ethyl, and wherein said fungicide consists essentially of fosetyl aluminum.
21. The method of claim 7 , wherein said at least one plant growth regulator and said at least one pigment and said at least one fungicide are applied sequentially.
22. The method of claim 7 , wherein said at least one plant growth regulator and said at least one pigment and said at least one fungicide are applied simultaneously.
23. An agricultural combination comprising:
(a) at least one plant growth regulator comprising ethephon, trinexapac ethyl, paclobutrazole, flurprimidol or a combination thereof;
(b) phthalocyanine; and
at least one fungicide comprising fosetyl aluminum, wherein the at least one plant growth regulator retards growth or reduces the number of seed heads in turf.
