Compounds to be released into biological environments can be subject to loss by degradation, dilution, leaching, or evaporation. The loss of effectiveness increases costs and may result in contamination of the surrounding environment. It is often desirable to extend the period of release. This formulation uses native, denatured starch and synthetic, biocompatible polymers to protect the active agent by encapsulating it. Exposure to the biological environment allows slow degradation of the encapsulating matrix and extended release of the agent. The particulate formulation can be made in any particle size distribution for spreading and cultivation, and it can be slurried for wet application without altering the release properties of the formulation. The type and proportion of biopolymers can be changed to adjust the release time and pattern as desired.
