Abstract: An inert dispersible granular substrate is suitable for use as a carrier for chemical agents. The granular substrate is comprised of one or more mineral components, the one or more mineral components having a bulk density of greater than about 70 pounds per cubic foot, one or more dispersibility additives; and one or more water soluble binders. The granular substrate has a bulk density of from greater than 55 pounds pcf to about 70 pcf, a water dispersibility of less than 5 minutes, a pH of from 6 to 8, and sufficient strength to survive formulation processing after 3 days of continuous exposure to a temperature of approximately 75° F. and a relative humidity of approximately 95%. Preferably, an active pesticide is applied to the dispersible granular substrate. The water dispersible granular substrates may be produced by forming a granular substrate admixture, pelletizing the admixture to form granular substrates, and drying the granular substrates.
