摘要： Polymeric materials are provided that are produced from a blend of hydrophilic and hydrophobic biodegradable polymers. The polymeric materials can form fibers, nonwoven fabrics, films, coatings, pellets, capsules, etc. A compound can be incorporated in the polymeric materials. The delivery of the compound can be controlled by diffusion of the compound from the polymeric material and during biodegradation of the polymeric material. The release rate is controlled by varying the composition of the polymeric material to control diffusion rates of the compound and/or biodegradation rate of the polymeric material. This technology provides methods for delivering and controlling release rates of pesticides and related compounds in agricultural and non-agricultural settings. When adhered to plants or plant parts, the polymeric materials can provide protection from insect and disease pests. In pellet or capsule form, pesticides can be delivered into seed furrows along with crop seeds, providing similar protection.
