Abstract

The invention pertains to new composition and a method for increasing the solubility of various agricultural compounds in water at a low pH. The compounds included in this patent are typically not soluble at pH ranges less than 7 to produce commercially viable liquid concentrates. This method requires the use of amine-containing surfactants and organic acids to lower the pH of various compounds and also keep them soluble in water.
