Zusammenfassung:A manufactured granular substrate composition suitable for use as a carrier for active chemical agents. The composition includes about 65 wt % or more of one or more mineral components having a bulk density greater than about 70 pounds per cubic foot. The composition also contains about 5 wt % to about 25 wt % of one or more light weight additives and up to 20 wt % of one or more water soluble binders. The resulting manufactured granular substrate is readily dispersable in water and has a bulk density of less than about 55 pounds per cubic foot with a size guide number of about 100 to about 230.
