The Kinetics of Fungicide and Herbicide Release from Slow-Release Formulations Prepared from Degradable Poly-3- Hydroxybutyrate

Release kinetics of the fungicide tebuconazole and the herbicide metribuzin from polymeric carriers was investigated.Carriers were prepared from poly-3-hydroxybutyrate as granules, films and 3D forms.The main mechanisms of pesticide release were discovered; kinetic constants for the first order model and Higuchi model were calculated.
