Abstract:
Seed-borne fungus Penicillium duclauxii was examined in this study to investigate its capability of synthesizing silver nanoparticles (Ag-NPs). In vitro experiments were conducted using corn-grain contaminating fungal isolate. Ag-NPs detection and characterization were assayed by the aid of spectroscopic techniques. Spectroscopy (energy dispersive), X-ray diffraction, transmission electron-microscope and optical absorption dimensions were employed. Ag-NPs with biosynthesized were used to test invitro against Bipolaris sorghicola; the cause of target leaf spot disease on sorghum plants. The myco-synthesis of Ag NPs using Penicillium duclauxii was proved in this study. Moreover, Bipolaris sorghicola was successfully inhibited by such Ag NPs in vitro.
