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 increasing zinc uptake in foliar applications, comprising:
spraying foliage with an admixture comprising citric acid, glutamic acid, a metal salt comprising zinc, and one or more agricultural chemicals; wherein the citric acid, glutamic acid and metal salt form a chelate to thereby prevent the metal salt from forming an insoluble solid in the admixture, 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, and wherein uptake of the metal salt comprising zinc by the foliage is increased by the admixture that is a liquid containing the chelate.

2 . The method of claim 1 , wherein the citric acid and glutamic acid are present at a molar ratio of about 2:1.

3 . The method of claim 2 , wherein the metal salt comprising zinc is present with the citric acid and glutamic acid at a molar ratio of about 2:2:1.

4 . The method of claim 3 , wherein the metal salt comprising zinc consists of zinc salt.

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

6 . The method of claim 1 , wherein the one or more agricultural chemicals comprises a monosaccharaide.

7 . The method of claim 1 , wherein the one or more agricultural chemicals comprises a fungicide.

8 . The method of claim 7 , wherein the one or more agricultural chemicals comprises a monosaccharaide.

9 . The method of claim 7 , 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.

10 . A method of producing an agricultural spray, comprising:
admixing citric acid, glutamic acid, a metal salt comprising zinc, and one or more agricultural chemicals; 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, or wherein the admixture is a liquid that does not exhibit at least one of flocculation, sludge, gelling, clumping, separation, or non-dispersible oil over at least one week.

11 . The method of claim 10 , wherein the metal salt comprising zinc consists of zinc salt.

12 . The method of claim 10 , wherein prior to the step of admixing, further comprising the step of providing a composition including the citric acid, glutamic acid and metal salt.

13 . An agricultural spray, comprising:
a metal salt comprising zinc, citric acid and glutamic acid in a molar ratio of about 2:14:1 to about 1:0.9:0.5, wherein the citric acid, the glutamic acid and the metal salt comprising 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, or wherein the admixture is a liquid that does not exhibit at least one of flocculation, sludge, gelling, clumping, separation, or non-dispersible oil over at least one week.

14 . The agricultural spray of claim 13 , wherein the citric acid and glutamic acid are present at a molar ratio of about 2:1.

15 . The agricultural spray of claim 14 , wherein the metal salt comprising zinc is present with the citric acid and glutamic acid at a molar ratio of about 2:2:1.

16 . The agricultural spray of claim 15 , wherein the metal salt comprising zinc consists of zinc salt.

17 . The agricultural spray of claim 13 , wherein the metal salt comprising zinc is present with the citric acid at a molar ratio of about 1:1, or wherein the metal salt comprising zinc is present with the glutamic acid at a molar ratio of about 2:1.

18 . The agricultural spray of claim 13 , wherein the one or more agricultural chemicals comprises a monosaccharaide.

19 . The agricultural spray of claim 13 , wherein the one or more agricultural chemicals comprises a fungicide.

20 . The agricultural spray of claim 19 , 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.
