Abstract

The invention relates to a colorant composition comprising humic acid and/or fulvic acid and a water soluble dye. The invention in particular relates to a colorant composition and method for imparting color to turf grass.

Claims

1. A method of imparting color to foliage, the method including applying an aqueous foliage colorant composition consisting of humic and fulvic acid, water and a water soluble dye, and optionally a water soluble fertilizer, a source of iron, a surfactant and an additive selected from the group consisting of an insecticide, a fungicide, a pesticide and a herbicide to the foliage.

2. The method of claim 1, wherein the foliage is turf grass.

3. The method of claim 2, wherein between about 24 to about 120 g humic and fulvic acid and between about 1.5 to about 7.5 g dye are applied per 100 m² turf grass.

4. The method of claim 1, wherein a water soluble fertilizer is present.

5. The method of claim 4, wherein the water soluble fertilizer is urea.

6. The method of claim 1, wherein a source of iron is present.

7. The method of claim 6, wherein the source of iron is ferric EDTA.

8. The method of claim 1, wherein an additive selected from the group consisting of an insecticide, fungicide, pesticide or herbicide is present.

9. The method of claim 1, wherein the dye is selected from the group consisting of acid blue 62 (Sodium 1-amino-4-(cyclohexylamino)-9,10-dihydro-9,10-dioxoanthracene-2-sulphonate);

acid blue 74 (Disodium 5,5′

-(2-(1,3-dihydro-3-oxo-2H-indazol-2-ylidene)-1,2-dihydro-3H-indol-3-one)disulphonate);

acid blue 1 (Hydrogen[4-[4-(diethylamino)-2′

,4′

-disulphonatobenzhydrylidene]cyclohexa-2,5-dien-1-ylidene]diethylammonium, sodium salt);

acid blue 185;

acid blue 9 (Dihydrogen(ethyl)[4-[4-[ethyl(3-sulphonatobenzyl)]amino]-2′

-sulphonatobenzhydrylidene]cyclohexa-2,5-dien-1-ylidene](3-sulphonatobenzyl)ammonium or disodium salt);

acid green 1 (Trisodium tris[5,6-dihydro-5-(hydroxyimino)-6-oxonaphthalene-2-sulphonato(2-)-N5,O6]ferrate(3-) and acid green 50 (Hydrogen[4-[4-(dimethylamino)-a-(2-hydroxy-3,6-disulphonato-1-naphthyl)benzylidene]cyclohexa-2,5-dien-1-ylidene]dimethylammonium, monosodium salt) or mixtures or any two or more thereof.

10. A method of imparting a green color to foliage, the method comprising applying to the foliage a composition consisting of humic acid, fulvic acid, water and a water soluble acid blue dye, and optionally a water soluble fertilizer, a source of iron, a surfactant and an additive selected from the group consisting of an insecticide, a fungicide, a pesticide and a herbicide.

11. The method of claim 10, wherein the foliage is turf grass.

12. The method of claim 11, wherein between about 24 to about 120 g humic and fulvic acid and between about 1.5 to about 7.5 g dye are applied per 100 m² turf grass.

13. The method of claim 10, wherein a water soluble fertilizer is present.

14. The method of claim 13, wherein the water soluble fertilizer is urea.

15. The method of claim 10, wherein a source of iron is present.

16. The method of claim 15, wherein the source of iron is ferric EDTA.

17. The method of claim 10, wherein an additive selected from the group consisting of an insecticide, fungicide, pesticide or herbicide is present.

18. The method of claim 10, wherein the dye is selected from the group consisting of acid blue 62 (Sodium 1-amino-4-(cyclohexylamino)-9,10-dihydro-9,10-dioxoanthracene-2-sulphonate);

acid blue 74 (Disodium 5,5′

-(2-(1,3-dihydro-3-oxo-2H-indazol-2-ylidene)-1,2-dihydro-3H-indol-3-one)disulphonate);

acid blue 1 (Hydrogen[4-[4-(diethylamino)-2′

,4′

-disulphonatobenzhydrylidene]cyclohexa-2,5-dien-1-ylidene]diethylammonium, sodium salt);

acid blue 185 and acid blue 9 (Dihydrogen(ethyl)[4-[4-[ethyl(3-sulphonatobenzyl)]amino]-2′

-sulphonatobenzhydrylidene]cyclohexa-2,5-dien-1-ylidene](3-sulphonatobenzyl)ammonium or disodium salt or mixtures or any two or more thereof.

19. A method of imparting color to foliage, the method including applying a foliage colorant composition consisting of humic acid, fulvic acid, water, and a water soluble dye to the foliage.

20. The method of claim 19 wherein a green color is imparted to the foliage and the water soluble dye is an acid blue dye.
