A large number of plant pathogens belongs to the kingdom fungi, which are responsible for some catastrophic diseases in crops. The diseases that are common in fruits and vegetables are mostly fungi originated. In the present work, an attempt has been made to evaluate the antifungal activity of biosynthesized sulphur nanoparticles (SNPs). Sulphur is an essential component in both agriculture and technology. Ocimum basilicum (Basil) leaves extract has been used as a surfactant in an acidic (oxalic) medium to synthesize Sulphur nanoparticles. Oxalic acid is a weak acid that meets the requirement of green synthesis fairly. Different characterization techniques such as XRD, UV-Vis, SEM and FTIR have been employed to assess the nanoparticles. Uv-Vis spectrum shows a peak at 298nm, which confirms the formation of Sulphur nanoparticles. A highly crystalline nature with crystalline size 58nm has been revealed by the XRD analysis. The linkage of biomolecules on the surface of Sulphur nanoparticles has been analyzed by the FTIR spectrum. The adsorption of biomolecules on the surface is responsible for ceasing the agglomeration process and increasing their adaptability with nature. SEM data shows the quasi-spherical shape of nanoparticles. Well diffusion assay has been performed to study the antifungal activity of SNPs against Alternaria triticina, Aspergillus niger and Fusarium oxysporum, and significant growth inhibition has been observed in the case of Aspergillus niger.
