In the past years, nanotechnology has been resorting to green synthesis as an eco-friendly or environmentally friendly technology rather than chemical methods. Of the metal oxide nanoparticles, zinc oxide (ZnO) has generated considerable interest because of its exceptional photocatalytic, UV-shielding, and antimicrobial activities. In the present work, ZnO nanoparticles were prepared in green approach using Azadirachta indica (neem) leaf extract as a reducing as well as stabilizing agent. The structure and morphology of the biosynthesized ZnO nanoparticles were investigated by Scanning Electron Microscopy (SEM) and X-Ray Diffraction (XRD) techniques. In addition, the antifungal activity of the prepared nanoparticles was examined against some phytopathogenic fungi such as Laetiporus sulphureus and Pycnoporus sanguineus. The characterization data showed that the green-formed ZnO nanoparticles were mainly spherical, crystalline and had notable antifungal efficacy, suggesting them as potential eco-friendly tools for managing fungal diseases.
