- 1. A suspension concentrate comprising glyphosate acid particles suspended in water and surfactant selected from the group consisting of cationic surfactant, anionic surfactant, and mixtures thereof.
- 11. A suspension concentrate comprising glyphosate acid and short chain alcohol ethoxylate nonionic surfactant having a short chain branched or linear alkyl having from 3 to 23 or fewer carbon atoms.

14. A herbicide composition comprising
a suspension concentrate comprising glyphosate acid, and acidifying agent other than sulfuric acid, in an amount so the pH of the herbicide composition is below the pKa of glyphosate acid.
-
19. A method of applying a herbicide composition, the method comprising
preparing a herbicide composition comprising a suspension concentrate comprising glyphosate acid, acidifying agent other than sulfuric acid, in an amount so the pH of the herbicide composition is below the pKa of glyphosate acid, and applying the herbicide composition to control plant growth.
-
26. A method of preparing a suspension concentrate comprising glyphosate acid, the method comprising
combining glyphosate acid particles with water and surfactant selected from the group consisting of cationic surfactant, anionic surfactant, short chain alcohol ethoxylate nonionic surfactant, and mixtures thereof, and mixing or agitating the water, glyphosate acid particles, and surfactant, to produce a suspension concentrate.
-
27. A method of preparing a suspension concentrate comprising glyphosate acid, the method comprising:
-
combining glyphosate acid particles with water, surfactant, and dispersant, wet milling the mixture of glyphosate acid particles, water, surfactant, and dispersant to reduce the size of glyphosate acid particles to a size that can be suspended in the water, surfactant, and dispersant, and using a high speed mixer to mix the water, glyphosate acid particles, surfactant, and dispersant, to produce a suspension concentrate comprising the glyphosate acid particles. - View Dependent Claims (28, 29)

30. A method of preparing a herbicide composition comprising glyphosate acid, the method comprising
preparing a suspension concentrate composition by a method comprising combining glyphosate acid particles with water and one or more of surfactant and dispersant, and mixing or agitating the water, glyphosate acid particles, and one or more of surfactant and dispersant, to produce a suspension concentrate containing the glyphosate acid particles, and combining the suspension concentrate composition with acidifying agent other than sulfuric acid.
