Augmented antifungal potential of benzothiazol-2-ylcarbamodithioates as hybrid-silver aqua nanoformulations

Abstract

This study was focused on the preparation of benzothiazol-2-ylcarbamodithioates-silver nanoconjugates (BCDTC-AgNPs) for their in vitro antifungal evaluation against various phytopathogenic fungi viz. Pyricularia grisea, Drechslera oryzae, Fusarium moniliforme and Ustilaginoidea virens. Benzothiazol-2-ylcarbamodithioates (BCDTCs) were used both as capping as well as stabilizing for silver nanoparticles (AgNPs). The prepared nanoconjugates were analysed by UV-visible and TEM studies. The comparative antifungal evaluation of BCDTC-AgNPs with precursor BCDTCs and AgNPs indicated the manifold increase in antifungal potential when applied as nanoconjugates. The promising results were comparable to the standard commercial fungicides Tilt and Bavistin, in most of the cases.
