Abstract
The increasing incidence of antifungal resistance and environmental hazards of synthetic fungicides create an urgent need for eco-friendly alternatives. In this regard, green nanotechnology has been developed as a promising approach for synthesis of biologically active nanomaterials. In this study, the efficiency of biosynthesized silver nanoparticles (AgNPs), using sunflower was evaluated. oil of Helianthus annuus L. as reducing and stabilizing agent with special reference to their antifungal activity and effects on mycotoxins production The synthesized nanoparticles were characterized by using UV-Vis and FTIR techniques. Their antifungal activity was evaluated against some fungal strains like Fusarium solani, Alternaria alternata and Aspergillus niger. Results showed significant inhibition of fungal growth and reduction of mycotoxin production of these fungi species. These findings underscore the promising role of plant-mediated AgNPs as eco-friendly antifungal agents for agricultural and biomedical applications.
