Abstract

The invention includes aqueous compatibilized pesticidal formulations and methods of making them. In typical embodiments, formulations comprise a first electrolytic pesticide and a second electrolytic pesticide, and about 30 to about 300 g/L of at least one alkyl polyglycoside. The invention also includes methods of preparing pesticidal formulations to increase the concentration of the electrolytic pesticides. The invention also includes storage and transport systems containing formulation embodiments. The invention also includes methods inhibiting pests.

First claim

What is claimed is:

1. A compatibilized aqueous pesticidal formulation comprising:
about 30 to about 300 g/L of at least one alkyl polyglycoside (APG); and
about 85 to about 600 g a.e./L of an electrolytic pesticide mixture (EPM) comprising at least:
glyphosate in a first salt form, and
a second herbicide selected from dicamba and fomesafen in a second salt form, wherein said first salt form is different from said second salt form.

2. The compatibilized formulation of claim 1 , further comprising about 1% to about 15%, by weight/volume %, of at least one hydrotrope chosen from a salt of xylene sulphonic acid, a salt of cumene sulphonic acid, and a salt of toluene sulphonic acid.

3. A method of inhibiting at least one pest in a crop area, the method comprising applying a formulation according to claim 1 to the crop area.

4. The method of claim 3 , further including diluting the formulation prior to applying.

5. A method of forming the compatibilized aqueous pesticidal formulation of claim 1 , the method comprising adding to a volume of water:
about 30 to about 300 g/L of at least one alkyl polyglycoside (APG); and
about 85 to about 600 g a.e./L of an electrolytic pesticide mixture (EPM) comprising at least the glyphosate and the second herbicide.

6. The method of claim 5 , the method comprising adding to a volume of water:
about 30 to about 300 g/L of at least one alkyl polyglycoside (APG);
about 75 to about 500 g a.e./L of the glyphosate; and
about 10 to about 400 g a.e./L of the second herbicide.

7. The compatibilized formulation of claim 1 , wherein said formulation comprises from about 250 to about 600 g a.e./L of said electrolytic pesticide mixture (EPM).

8. A compatibilized aqueous pesticidal formulation comprising:
about 30 to about 300 g/L of at least one alkyl polyglycoside (APG);
about 200 to about 600 g a.e./L of an electrolytic pesticide mixture (EPM) comprising at least:
glyphosate in a first salt form and
a second herbicide selected from dicamba and fomesafen in a second salt form, said first salt form being different from said second salt form; and

about 1% to about 15%, by weight/volume %, of at least one hydrotrope chosen from a salt of xylene sulphonic acid, a salt of cumene sulphonic acid, and a salt of toluene sulphonic acid.

9. The formulation of claim 1 , wherein the second herbicide is dicamba and the second salt form is a diglycoamine salt.

10. The formulation of claim 1 , wherein the second herbicide is fomesafen and the second salt form is a sodium salt.

11. The formulation of claim 9 , where the first salt form is a potassium salt.

12. The formulation of claim 10 , where in the first salt form is a potassium salt.

13. The formulation of claim 1 , wherein the glyphosate and the second herbicide are present at a glyphosate:second herbicide ratio of from about 9:1 to about 1:3.

14. The formulation of claim 1 , wherein the glyphosate and the second herbicide are present at a glyphosate:second herbicide ratio of from about 3:1 to about 1:3.

15. The formulation of claim 8 , wherein the second herbicide is dicamba and the second salt form is a diglycoamine salt.

16. The formulation of claim 15 , wherein the first salt form is a potassium salt.

17. The formulation of claim 8 , wherein the second herbicide is fomesafen and the second salt form is a sodium salt.

18. The formulation of claim 17 , wherein the first salt form is a potassium salt.
