Abstract

Herbicidal concentrate compositions containing a combination of glyphosate salt and dicamba salt are provided. For example, a low volatility aqueous herbicidal concentrate composition including a glyphosate salt, dicamba salt, and a surfactant is described, wherein (i) the composition contain a total active herbicide loading of glyphosate salt and dicamba salt of at least about 450 grams acid equivalent per liter; (ii) the pH of the concentrate composition is less than about 5.7; and (iii) the acid equivalent weight ratio of glyphosate salt to dicamba salt is from about 1:1 to about 3:1.

Claims
