Abstract:
1. A method of improving the compatibility of aqueous herbicide solutions containing a water soluble salt of 2,4-D and a water soluble salt of glyphosate, wherein the solutions contain one or more inorganic cations selected from the group consisting of NH 4 + , Na + , K + , Ca 2+ , Mg 2+ , Fe 2+ , Fe 3+ , Cu 2+ , Mn 2+ and Zn 2+ , which comprises adding to the aqueous herbicide solution one or more polyethylenimine or polyvinylamine crystallization inhibitors, wherein the pH of the aqueous herbicide solution is below or about 6.5, the weight percent ratio of 2,4-D to glyphosate on an acid equivalent basis is from about 16:1 to about 1:16, and the crystallization inhibitor is added in an amount sufficient to improve compatibility and reduce the amount of solids formed.
