Abstract
Copper sulfide nanoparticles in aqua-dispersed form were prepared by reaction of copper ions with different sulfide sources by sonochemical irradiation method. The products were characterized by Transmission Electron Microscopy (TEM) and UV-Visible spectroscopy (UV-Vis). All the synthesized samples of nanoparticles were screened for their in vitro antifungal potential against various phytopathogenic fungi viz. Drechslera oryzae, Alternaria alternata, Ustilago tritici and Ustilagonoidea virens by spore germination technique, using Propiconazole and Carboxin + Thiram as 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 10 g/ml, which was multifold lower than the standards used.
