Abstract

The invention is directed to methods and compositions for increasing a growth characteristic of a plant, increasing nutrient use efficiency of a plant, or improving a plant's ability to overcome stress comprising applying a composition comprising ketosuccinamate, a derivative thereof, or a salt thereof, to the plant or to a propagation material of the plant.

First claim

What is claimed:

1. A method for increasing a growth characteristic of a plant, or increasing nutrient use efficiency of a plant, or improving a plant's ability to overcome stress comprising applying to a plant or to a propagation material of a plant a composition comprising ketosuccinamate, dimeric ketosuccinamate; 4-amino-2,4-dioxobutanoic acid; (S)-4-oxo-2-azetidinecarboxylic acid; (R)-4-oxo-2-azetidinecarboxylic acid; 4,8-dioxo-1,5-diazocane-2,6-dicarboxylic acid; or 2,6-dihydroxy-4,8-dioxo-1,5-diazocane-2,6-dicarboxylic acid, or a salt thereof.

2. The method of claim 1 , wherein the applying is to a part of the plant that is foliage.

3. The method of claim 1 , wherein the applying is to a seed.

4. The method of claim 1 , wherein the application is pre-emergence.

5. The method of claim 1 , wherein the composition is an aqueous solution, a non-aqueous solution, a suspension, a gel, a foam, a paste, or an emulsion.

6. The method of claim 5 wherein the composition is an aqueous solution.

7. The method of claim 1 , wherein the composition further comprises a surfactant, a humectant, an adjuvant, an antioxidant, a stabilizer, a plant macronutrient, a plant micronutrient, a pesticide, a fungicide, an antiviral, an anti-bacterial, a herbicide, or a combination thereof.

8. The method of claim 1 , wherein the composition is a powder, a dust, or a solid.

9. The method of claim 1 , wherein the composition further comprises a plant growth stimulating compound.

10. The method of claim 9 , wherein the plant growth stimulating compound is selected from the group of (R)-2-hydroxy-5-oxopyrrolidine-2-carboxylic acid, (S)-5-oxopyrrolidine-2-carboxylic acid, L-Pyroglutamate, and combinations thereof.

11. The method of claim 9 or claim 10 , wherein the ratio of the ketosuccinamate, dimeric ketosuccinamate; 4-amino-2,4-dioxobutanoic acid; (S)-4-oxo-2-azetidinecarboxylic acid; (R)-4-oxo-2-azetidinecarboxylic acid; 4,8-dioxo-1,5-diazocane-2,6-dicarboxylic acid; or 2,6-dihydroxy-4,8-dioxo-1,5-diazocane-2,6-dicarboxylic acid, to the plant growth stimulating compound is from about 50:50 to about 40:60.

12. The method of claim 1 , wherein the applying is post-emergence.

13. A composition comprising
ketosuccinamate, dimeric ketosuccinamate; 4-amino-2,4-dioxobutanoic acid; (S)-4-oxo-2-azetidinecarboxylic acid; (R)-4-oxo-2-azetidinecarboxylic acid; 4,8-dioxo-1,5-diazocane-2,6-dicarboxylic acid; or 2,6-dihydroxy-4,8-dioxo-1,5-diazocane-2,6-dicarboxylic acid, or a salt thereof; and
a plant growth stimulating compound selected from the group consisting of (R)-2-hydroxy-5-oxopyrrolidine-2-carboxylic acid, (S)-5-oxopyrrolidine-2-carboxylic acid, L-Pyroglutamate, and combinations thereof.

14. The composition of claim 13 , further comprising a carrier.

15. The composition of claim 13 or claim 14 , wherein the composition is in the form of an aqueous solution, a non-aqueous solution, a suspension, a gel, a foam, a paste, or an emulsion.

16. The composition of claim 15 , wherein the composition is an aqueous solution.

17. The composition of claim 13 , wherein the ratio of the ketosuccinamate, dimeric ketosuccinamate; 4-amino-2,4-dioxobutanoic acid; (S)-4-oxo-2-azetidinecarboxylic acid; (R)-4-oxo-2-azetidinecarboxylic acid; 4,8-dioxo-1,5-diazocane-2,6-dicarboxylic acid; or 2,6-dihydroxy-4,8-dioxo-1,5-diazocane-2,6-dicarboxylic acid, or a salt thereof to the plant growth stimulating compound is from about 50:50 to about 40:60.

18. The composition of claim 13 , wherein the ketosuccinamate derivative is dimeric ketosuccinamate; 4-amino-2,4-dioxobutanoic acid; (S)-4-oxoazetidine-2-carboxylic acid; 4,8-dioxo-1,5-diazocane-2,6-dicarboxylic acid; or a combination thereof.

19. The composition of claim 13 , further comprising a surfactant, a humectant, an adjuvant, an antioxidant, a stabilizer, a plant macronutrient, a plant micronutrient, a pesticide, a fungicide, an antiviral, an anti-bacterial, a herbicide, or a combination thereof.

20. The composition of claim 13 , further comprising a microbe.

21. The composition of claim 20 , wherein the microbe is a nitrogen fixing microbe or a microrrhizae.

22. The composition of claim 13 or claim 14 , in the form of a powder, a dust, or a solid.

23. A method of preparing the composition of claim 18 comprising combining
ketosuccinamate, dimeric ketosuccinamate; 4-amino-2,4-dioxobutanoic acid; (S)-4-oxo-2-azetidinecarboxylic acid; (R)-4-oxo-2-azetidinecarboxylic acid; 4,8-dioxo-1,5-diazocane-2,6-dicarboxylic acid; or 2,6-dihydroxy-4,8-dioxo-1,5-diazocane-2,6-dicarboxylic acid, or a salt thereof;
the plant growth stimulating compound; and
the carrier.
