6. A method of applying a herbicide application composition, the method comprising
preparing a herbicide application composition comprising a suspension concentrate comprising glyphosate acid, acidifying agent in an amount so the pH of the herbicide application composition is below the pKa of glyphosate acid, and applying the herbicide application composition to control plant growth.

13. 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 (14, 15)

16. A method of preparing a herbicide application 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 adding acidifying agent in an amount so the pH of the herbicide application composition is below the pKa of glyphosate acid.
