Abstract
In the current study, silver nanoparticles (Ag NPs) were synthesized using Aspergillus versicolor. The synthesized Ag NPs were characterized by UV-Vis spectrum, TEM, XRD, SEM, and EDS, which revealed that the synthesized NPs had a face-centred cubic similarity. The rapid synthesis of Ag NPs in fungal filtrate showed bright sunlight. The maximum absorbance of Ag NPs was observed at 620 nm which is a sign of Ag NPs. The TEM analysis revealed the spherical shape with the size ranged between 5 to30 nm and EDS showed the presence of Ag at 3kev. The antifungal activity of biogenic Ag NPs was evaluated against white mold (Sclerotinia sclerotiorum) and grey mould (Botrytis cinerea) in strawberry (Fragaria x ananassa). The results showed that synthesized silver nanoparticles exhibit significant antifungal potential on both pathogens in a concentration-dependent manner. The maximum reduction in both fungi was observed at 150 ppm of Ag NPs.
