Abstract

An agricultural spray may be produced by admixing citric acid and glutamic acid with a metal salt and a pesticide or other agricultural chemical containing components capable of precipitating with the metal salt in the admixture. The citric acid and the glutamic acid chelate with the metal salt to provide a stability and compatibility-enhancing composition, thereby preventing the metal salt from forming an insoluble solid within the admixture. Such a composition may be produced by admixing citric acid and glutamic acid at a molar ratio of about 6.8:0.5 to about 1:0.29. The composition may include a metal sat, citric acid and glutamic acid in a molar ratio of about 1:6.8:0.5 to about 1:1:0.29 and a pesticide.

First claim

What is claimed is:

1. A method of spraying an agricultural spray admixture, comprising:
spraying an admixture comprising citric acid and glutamic acid with a metal salt and a pesticide, the pesticide comprising phosphate, the metal salt comprising one or more zinc, boron, copper, iron, chloride, manganese, molybdenum, cobalt, magnesium, calcium, or nickel;
wherein the citric acid glutamic acid and metal salt form a chelate to thereby prevent the metal salt from forming an insoluble solid with the phosphate, and
wherein the citric acid and the glutamic acid are present in the composition at a molar ratio of about 6.8:0.5 to about 1:0.29,
wherein the admixture remains stable, non-precipitated for at least 72 hours.

2. The method of claim 1 , wherein the metal salt is present with the citric acid and the glutamic acid at a molar ratio of about 1:6.8:0.5 to about 1:1:0.29.

3. The method of claim 1 , wherein the pesticide comprises N-(phosphonomethyl)glycine.

4. The method of claim 1 , wherein the composition further includes at least one insecticide and/or at least one fungicide.

5. The method of claim 1 , wherein the composition is free of ethylenediaminetetraacetic acid.

6. The method of claim 1 , wherein the composition does not exhibit at least one of flocculation, sludge, gelling, clumping, precipitation, separation, or non-dispersible oil over at least one week.

7. The method of claim 1 , wherein the admixture remains stable, non-precipitated for at least 42 days.

8. A method of producing a stability and compatibility-enhancing composition, comprising:
admixing a composition comprising citric acid and glutamic acid at a molar ratio of about 6.8:0.5 to about 1:0.29, the composition further comprising a metal salt, the metal salt comprising one or more of zinc, boron, copper, iron, chloride, manganese, molybdenum, cobalt, magnesium, calcium, or nickel; wherein the citric acid, glutamic acid and metal salt form a chelate; and
wherein the composition remains stable, non-precipitated over 72 hours.

9. The method of claim 8 , wherein the molar ratio of the chelated composition of the metal salt, the citric acid and the glutamic acid is about 1:6.8:0.5 to about 1:1:0.29.

10. The method of claim 8 , wherein the metal salt includes a metal oxide.

11. The method of claim 8 , wherein the composition does not exhibit at least one of flocculation, sludge, gelling, clumping, precipitation, separation, or non-dispersible oil over at least one week.

12. The method of claim 8 , wherein the composition remains stable, non-precipitated for at least 42 days.

13. The method of claim 8 , further comprising producing an agricultural spray by mixing the composition with one or more of a pesticide or a fertilizer.

14. The method of claim 13 , wherein the composition comprises at least the pesticide, the pesticide comprising one or more of: N-(phosphonomethyl)glycine, 4-Dichlorophenoxyacetic acid, bentazon, 3,6-dichloro-o-anisic acid, 3,6-dichloro-2-methoxybenzoic acid, 1-chloro-3-ethylamino-5-isopropylamino-2,4,6-triazine, amide herbicides, arsenical herbicides, carbamate and tiocarbamate herbicides, carboxylic acid herbicides, dinitronailine herbicides, heterocyclic nitrogen-containing herbicides, organophosphate compounds, urea herbicides, and quaternary herbicides, 5-[2-chloro-4-(trifluoromethyl)phenoxy]-N-(methylsulfonyl)-2-nitrobenzamide, tembotrione or an ester of the pesticide.

15. The method of claim 8 , wherein the composition is a solid.

16. A stability and compatibility-enhancing admixture of a composition comprising a metal salt, citric acid and glutamic acid in a molar ratio of about 1:6.8:0.5 to about 1:1:0.29 and a pesticide, the metal salt comprising one or more of zinc, boron, copper, iron, chloride, manganese, molybdenum, cobalt, magnesium, calcium, or nickel; wherein the citric acid, glutamic acid and metal salt form a chelate; and
wherein the admixture remains stable, non-precipitated for at least 72 hours.

17. The admixture of claim 16 , wherein the pesticide comprises one or more of: N-(phosphonomethyl)glycine, 4-Dichlorophenoxyacetic acid, bentazon, 3,6-dichloro-o-anisic acid, 3,6-dichloro-2-methoxybenzoic acid, 1-chloro-3-ethylamino-5-isopropylamino-2,4,6-triazine, amide herbicides, arsenical herbicides, carbamate and tiocarbamate herbicides, carboxylic acid herbicides, dinitronailine herbicides, heterocyclic nitrogen-containing herbicides, organophosphate compounds, urea herbicides, and quaternary herbicides, 5-[2-chloro-4-(trifluoromethyl)phenoxy]-N-(methylsulfonyl)-2-nitrobenzamide, tembotrione or an ester of the pesticide.

18. The admixture of claim 16 , wherein the composition does not exhibit at least one of flocculation, sludge, gelling, clumping, precipitation, separation, or non-dispersible oil over at least one week.

19. The admixture of claim 16 , wherein the admixture remains stable, non-precipitated for at least 42 days.

20. The admixture of claim 16 , wherein the composition is free of ethylenediaminetetraacetic acid.
