Slow-release agricultural pesticide formulations: state of the art

The need for a long-term sustaining of optimal concentrations applied pesticides in the soil agriculture resulted development systems controlled release active substances. Such are based on use eco-friendly carrier materials that harmless to plants, humans and environment. Inorganic substances (e.g., clays or alike substances), biodegradable polymers natural synthetic origin, blends such their composites with inorganic fillers can be used as carriers. deposited released by diffusion or, case polymers, degradation carrier. carriers usually impregnated pesticide. As there is wide range methods obtaining forms. Namely, these microsphere nanoparticle formation, film casting, tablet pressing, form gelatinizing, coprecipitation pesticide polymer from solution. Co-extrusion at temperatures below temperature components another promising method
