Method of improving grass quality
View Patent ↗The invention relates to a method of improving grass quality comprising applying an effective amount of a composition containing a phthalocyanine to the grass in the substantial absence of phosphorous acid, monoalkyl esters of phosphorous acid, or salts thereof.
1. A method of improving quality of grass under stress comprising applying to grass a composition comprising an amount of a phthalocyanine effective to improve the quality of grass under stress, wherein
(i) the composition does not include phosphorous acid or a salt thereof or a monoalkyl ester of phosphorous acid or a salt thereof;
(ii) about 0.01 to about 2 kg per hectare of said phthalocyanine is applied to said grass; and wherein the application of said composition to grass improves the quality of grass under stress
(iii) wherein said phthalocyanine is a copper phthalocyanine, and
(iv) said composition does not include a metallic ethylene bisdithiocarbamate contact fungicide.
2. The method according to claim 1 , wherein
(v) the composition does not include an effective amount of other fungicides.
3. The method of claim 1 , comprising applying to grass an effective amount of a composition comprising from 1% to 95% by weight of the copper phthalocyanine on a solid support, from 0 to 5% by weight of a wetting agent, and from 3 to 10% by weight of a dispersant.
4. The method of claim 1 , wherein said composition does not include a polymer.
5. The method of claim 1 , wherein about 0.1 to about 1 kg per hectare of said phthalocyanine is applied to grass.
6. The method of claim 1 , wherein said stress is heat induced stress.
7. A method of improving quality of grass under stress comprising applying to grass a composition comprising an amount of a phthalocyanine effective to improve the quality of grass under stress, wherein
(i) the composition does not include phosphorous acid or a salt thereof or a monoalkyl ester of phosphorous acid or a salt thereof;
(ii) about 0.01 to about 2 kg per hectare of said phthalocyanine is applied to said grass; and wherein application of said composition to said grass improves the quality of the grass under stress
(iii) wherein said phthalocyanine is selected from the group consisting of Pigment Blue 16, Vat Blue 29, Pigment Blue 15, Heliogen Green GG, Ingrain Blue 14, Ingrain Blue 5, Ingrain Blue 1, Pigment Green 37, and Pigment Green 7, and
(iv) said composition does not include a metallic ethylene bisdithiocarbamate contact fungicide.
8. The method of claim 7 , wherein about 0.1 to about 1 kg per hectare of said phthalocyanine is applied to grass.
9. The method of claim 7 , wherein said stress is heat induced stress.
10. A method of improving quality of grass under stress comprising applying to grass a composition comprising an amount of a phthalocyanine effective to improve the quality of grass under stress, wherein
(i) the composition does not include phosphorous acid or a salt thereof or a monoalkyl ester of phosphorous acid or a salt thereof;
(ii) about 0.01 to about 2 kg per hectare of said phthalocyanine is applied to said grass; and wherein the application of said composition to grass improves the quality of grass under stress
(iii) wherein said composition comprises a fungicide, wetting agent, dispersant, and stabilizer, and
(iv) said composition does not include a metallic ethylene bisdithiocarbamate contact fungicide.
11. The method of claim 10 , wherein about 0.1 to about 1 kg per hectare of said phthalocyanine is applied to grass.
12. The method of claim 10 , wherein said stress is heat induced stress.
