peanuts are vulnerable Assignment toxigenic and cause to fungal infections during long term storage. Funei infecting peanuts are health hazards. The goal of this study was isolation and identification of frs in peanuts and use of nanoparticles (AgNPs) to inhibit them. For this purpose, firstty, we have silver isolated fungi from infected peanuts and identified on the basis of morphological and molecular study. Out of the total 54 fungal isolates, 47 were found to be Aspergillus spp and other belongs to Penicillium spp. and Macrophomina phaseolina. Biochernical assay was performed to identify cultures of Aspergillus favus from other species of this genus by inoculating it on Aspergulus Differentiation Medium (ADM). Thirty-one isolates were found to be A novus. Todcity of Aspenetlus spp. was evaluated on Yeast Extract sucrose agar (YES) medium additive methylated b- with an different n and nine isolates were found toxigenic. Secondly, were synthesized from plants and their characterization was performed using various analytical t such as uvevisible spectrophotometer, Fourier Transform infrared spectroscopy, zetasizer and Nanoparticle Tracking Analysis, etc. Further, antifungal potential of thus synthesized AgNPs was evaluated. All the synthesized AgNPs possess ability to inhibit fungal growth. cymbopogon citrotus leaf extract mediated AgNPs were found to have prominent antifungal potential against att test fungi and its minimum inhibitory concentration (MIC) was found to be 20 mg / rnt. The biogenic approach proposed in the present study is eco-friendly. safe and economical viable. A8NPs also reported to have significant antifungal activity asainst toxigenic isolates of peanuts, hence such AgNPs can be effectively used for the management of toxigenic pathogens.
