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 admixture, comprising:
spraying an admixture comprising citric acid, glutamic acid, a metal salt and one or more agricultural chemicals, the metal salt comprising one or more zinc, boron, copper, iron, chloride, manganese, molybdenum, cobalt, magnesium, calcium, nickel, vanadium, or chromium;
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 one or more agricultural chemicals, and
wherein the citric acid and the glutamic acid are present in the agricultural spray at a molar ratio of about 14:1 to about 0.9:0.5,
wherein the admixture is a liquid that remains stable, non-precipitated for at least 72 hours.

2. The method of claim 1 , wherein the one or more agricultural chemicals includes at least one of:
one or more pesticides;
one or more fertilizers; or
one or more additional agricultural chemicals containing a component capable of precipitating with the metal salt in the absence of the citric acid and the glutamic acid.

3. The method of claim 1 , wherein the citric acid and the glutamic acid are present in the agricultural spray at a molar ratio of about 6.8:0.5 to about 1:0.29.

4. 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 2:14:1 to about 1:0.9:0.5.

5. The method of claim 1 , wherein the metal salt is present with the citric acid and glutamic acid at a molar ratio of about 2:2:1, about 1:0.9:0.5, or about 1:1:0.29.

6. The method of claim 1 , wherein the admixture 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 , further comprising admixing the citric acid, glutamic acid, and the metal salt.

8. A method of producing an agricultural spray, comprising:
admixing citric acid, glutamic acid, a metal salt and one or more agricultural chemicals, the metal salt comprising one or more of zinc, boron, copper, iron, chloride, manganese, molybdenum, cobalt, magnesium, calcium, nickel, vanadium, or chromium;
wherein the citric acid and the glutamic acid are admixed at a molar ratio of about 14:1 to about 0.9:0.5;
wherein the citric acid, glutamic acid and metal salt form a chelate; and
wherein the agricultural spray is a liquid that remains stable, non-precipitated over 72 hours.

9. The method of claim 8 , wherein the one or more agricultural chemicals include at least one of:
one or more pesticides;
one or more fertilizers; or
one or more additional agricultural chemicals containing a component capable of precipitating with the metal salt in the absence of the citric acid and the glutamic acid.

10. The method of claim 8 , wherein the one or more agricultural chemicals comprise one or more pesticides, the one or more pesticides 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 thiocarbamate herbicides, carboxylic acid herbicides, dinitroaniline 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.

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

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

13. The method of claim 8 , wherein the agricultural spray remains stable, non-precipitated for at least 42 days.

14. The method of claim 8 , further comprising providing a composition including the citric acid and glutamic acid with a metal salt; and
wherein, after providing the composition, admixing citric acid and glutamic acid with a metal salt and one or more agricultural chemicals includes admixing the composition with the one or more agricultural chemicals.

15. The method of claim 14 , wherein providing the composition includes admixing the citric acid, glutamic acid, and the metal salt.

16. An agricultural spray, comprising:
a metal salt, citric acid and glutamic acid in a molar ratio of about 2:14:1 to about 1:0.9:0.5, the metal salt comprising one or more of zinc, boron, copper, iron, chloride, manganese, molybdenum, cobalt, magnesium, calcium, or nickel, vanadium, or chromium; wherein the citric acid, glutamic acid and metal salt form a chelate; and
one or more agricultural chemicals;
wherein the agricultural spray is a liquid that remains stable, non-precipitated for at least 72 hours.

17. The agricultural spray of claim 16 , wherein the admixture includes at least one of:
one or more pesticides;
one or more fertilizers; or
one or more additional agricultural chemicals containing a component capable of precipitating with the metal salt in the absence of the citric acid and the glutamic acid.

18. The agricultural spray of claim 16 , wherein the one or more agricultural chemicals comprise one or more pesticides, the one or more pesticides 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 thiocarbamate herbicides, carboxylic acid herbicides, dinitroaniline 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.

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

20. The agricultural spray of claim 16 , wherein the agricultural spray remains stable, non-precipitated for at least 42 days.
