Growth enhancement of plant by using cationic guars
The present invention provides a method for increasing the growth of a plant by contacting a seed of the plant with a composition comprising a cationic guar having an average molecular weight of between 2,000 Daltons and 90,000 Daltons. The present invention also provides a seed treated with a cationic guar having an average molecular weight of between 2,000 Daltons and 90,000 Daltons.
1. A method for increasing the growth of a plant which comprises the step of contacting a seed of said plant with a composition comprising guar hydroxypropyltrimonium chloride having an average molecular weight of between 10,000 Daltons and 50,000 Daltons and having a Degree of Substitution of between 0.005 and 3,
wherein the composition is in the form of a liquid composition or a solid composition, wherein the liquid composition is a suspension, a dispersion, a slurry, or a solution in a liquid carrier selected from water, organic solvents, oils or a mixture thereof, and the solid composition is a powder, a particle, an agglomerate, a flake, a granule, a pellet, a tablet, or a paste.
2. The method according to claim 1 , wherein the method comprises coating the seed of said plant with said composition.
3. The method according to claim 1 , wherein the method comprises at least the steps of:
a) the seed of said plant is implanted in a hole or a furrow in the soil; and
b) said composition is applied to surround or partially surround, or to be adjacent to the seed of said plant so that the seed of said plant comes into contact with said composition.
4. The method according to claim 1 , wherein said composition further comprises a carrier.
5. The method according to claim 1 , wherein the method comprises at least the steps of:
a) administering said composition to soil in which said plant is cultivated; and
b) the seed of said plant is applied to the soil so that the seed of said plant comes into contact with said composition.
6. The method according to claim 1 , wherein said plant is selected from the group consisting of: corn, wheat, sorghum , soybean, tomato, cauliflower, radish, cabbage, canola, lettuce, rye grass, grass, rice, cotton, sunflower, and mixtures thereof.
7. The method according to claim 1 , wherein the guar hydroxypropyltrimonium chloride has a Degree of Substitution of between 0.005 and 1.
8. The method according to claim 1 , wherein the cationic guar hydroxypropyltrimonium chloride has a Degree of Substitution of between 0.12 and 0.5.
9. The method according to claim 1 , wherein said composition further comprises a bioactive ingredient.
10. The method according to claim 1 , wherein said composition further comprises a plant biostimulant.
11. The method of claim 1 , wherein the guar hydroxypropyltrimonium chloride is from 1 wt % to 60 wt % based on the total weight of the composition.
12. The method of claim 1 , wherein the composition does not include a surfactant.
13. A seed coated with a composition comprising at least guar hydroxypropyltrimonium chloride,
wherein the guar hydroxypropyltrimonium chloride has an average molecular weight of between 10,000 Daltons and 50,000 Daltons and having a Degree of Substitution of between 0.005 and 3, and
wherein the composition is in the form of a liquid composition or a solid composition, wherein the liquid composition is a suspension, a dispersion, a slurry, or a solution in a liquid carrier selected from water, organic solvents, oils or a mixture thereof, and the solid composition is a powder, a particle, an agglomerate, a flake, a granule, a pellet, a tablet, or a paste.
14. The seed of claim 13 , wherein the guar hydroxypropyltrimonium chloride is from 1 wt % to 60 wt % based on the total weight of the composition.
15. The seed of claim 13 , wherein the composition does not include a surfactant.
