ABSTRACT:
Water dispersible agricultural chemical formulations are disclosed wherein the individual granules are coated with a water-soluble film. The water-soluble film coating on the granules thus significantly reduces any chemical residue on interior surfaces of containers used to package the formulations for transport/handling, while it does not affect dispersibility of granules and providing the end-user with a variety of crop application rates--i.e., since the entire package does not need to be used. In preferred forms, the present invention is embodied in water dispersible agricultural chemical formulations wherein the water-soluble coating is polyvinyl alcohol, sodium silicate or an alkyl cellulose (e.g., methyl cellulose), of which, polyvinyl alcohol is particularly preferred.
