| dc.description.abstract | Zinc sulfide nanoparticles in aqua-dispersed form were prepared by reaction of zinc acetate with sodium sulfide by sonochemical method. Zinc ion and sulfide ion coated ZnS nanoparticles were prepared in different molar ratios of ion to ZnS nanoparticles. The products were characterized by Transmission Electron Microscopy (TEM), UV-Visible spectroscopy (UV-Vis), Fourier Transform Infrared Spectroscopy (FT-IR), Scanning Electron Microscopy (SEM) and Energy Dispersive Spectroscopy (EDS). All the synthesized samples of zinc sulfide nanoparticles were screened for their in vitro antifungal potential against various phytopathogenic fungi viz. C. capsici, P. drechsleri, P. cubensisand P. parasiticaby applying spore germination inhibition technique, using Copper Oxychloride and Metalaxyl-M + Mancozebas a standard for comparison of the results. The prepared samples exhibited excellent broad spectrum inhibitory activity against all the test fungi, at concentration as low as 5μg/ml, which was multifold lower than the standards used. ZnS:Zn+2(1:5) exhibited better results among all samples. | en_US |
