Procedure

In another example, a dispersion or emulsion of 30% by weight 2,4-dichlorophenoxy acetic acid (2,4-D) and 70% by weight dicamba is prepared in water, at a concentration of 45% by weight of the 2,4-D and dicamba mixture. Thirty grams of the 2,4-D/dicamba mixture is added to a 50 ml (milliliter) beaker, and while this mixture is mixed vigorously, 1.5 grams of sodium montmorillonite (i.e., POLARGEL NF from AMCOL International Corporation) is added. The weight ratio of clay to (2,4-D dicamba mixture) is--1.9. The mixture is vigorously mixed and heated for 1 hour at 85° C.
