Silver nanoparticles and polyphenol inclusion compounds composites for Phytophthora cinnamomi mycelial growth inhibition

Phytophthora cinnamomi, responsible for “root rot” or “dieback” plant disease, causes a significant amount of economic and environmental impact. In this work, the fungicide action of nanocomposites based on silver nanoparticles and polyphenol inclusion compounds, which feature enhanced bioavailabili...
