Herbicidal concentrate compositions containing glyphosate salts and tank mix compositions containing a combination of glyphosate salt and dicamba salt herbicides are described. A method of preparing a tank mix composition comprising a glyphosate component and a dicamba component is also described. The method includes combining a glyphosate concentrate composition, a dicamba composition comprising one or more salts of dicamba and dilution water to form the tank mix composition. The glyphosate concentrate composition comprises a glyphosate salt selected from the group consisting of the monoethanolamine salt, the potassium salt, and mixtures thereof at a glyphosate loading of at least about 240 grams acid equivalent per liter (g a.e./l), and the pH of a 5 wt. % acid equivalent dilution of the glyphosate concentrate composition is from about 5 to about 6.5.
