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.
A dry, flowable, water-dispersible granular agricultural chemical having a water-soluble coating layer of polyvinyl alcohol on individual granules thereof which is present in an amount between about 0.01 to about 1.0 wt. %.
A dry, flowable, water-dispersible granular agricultural chemical which comprises granules of quinclorac, wherein individual ones of said quinclorac granules are coated with a layer of water-soluble polyvinyl alcohol in an amount between about 0.01 to about 1.0 wt. % sufficient to prevent more than 4.0 ppm of the coated quinclorac granules from remaining as a residue on interior surfaces of a container which contains the same.
