Activity of Biosynthesized Silver Nanoparticles in Combination with Synthetic and Natural Fungicide Against Some Pathogenic Fungi

Abstract

Silver nanoparticles have been synthesized biologically using Aspergillus foetidus MTCC8876 fungi and then characterized the same by various biophysical and biochemical techniques. It is observed that this synthesized nanoparticle have very potential antifungal activity against some pathogenic fungi. In this experiment we used some synthetic and natural fungicide tebuconazole, trifloxystrobin and hexaconazole, as well as plant extract of ginger and teak. These fungicides are well known and have been used to control the fungal infection of plant. We observed the effect of silver nanoparticles in combination with systematic as well as natural fungicide against some Aspergillus sp. and Fusarium sp. It was observed that the diameter of inhibitory zone of fungicide + silver nanoparticles were higher compare to only fungicide or only silver nanoparticles against pathogenic fungi. So, it is assumed that the silver nanoparticles are very useful antifungal substance in-combination with systematic and natural fungicide to control the pathogenic fungi.
