| Abstract | Pesticides incorporated into granules are a popular formulation option. Ideally, a granule should offer high liquid holding capacity, high resistance to attrition, low dust and chemical inertness. Clay granules offer a formulator all of the above benefits except, on occasion, chemical inertness. Clays possess chemical activity arising From acid sites associated with the clay surface. While this is not always a problem, in some instances a deactivator (e.g. dipropylene glycol) is incorporated into the formulation to counteract the surface activity of the clays. In this paper, a clay granule that has been processed to lower surface activity is described. The physical characteristics of the new granule are contrasted with clay granules processed in the traditional manner. The stability of two phosphate ester pesticides on the new granule is presented. In one instance, the new granule results in a decrease in the amount of deactivator needed for a stable formulation. In the other instance, the new granule results in a formulation that is stable with no deactivator. |
