Synthesis of Biogenic silver nanoparticles using plant growth-promoting bacteria: Potential use as biocontrol agent against phytopathogens

Biogenic nanoparticles (NPs) derived from microbes present an excellent opportunity to deal with various challenges in medicine, diagnosis, environment and agriculture. In the area of agriculture sciences, researchers are facing related excessive utilization pesticides which can be answered by utilizing plant growth-promoting (PGP) microbes. Herein, we have employed culture filtrate two PBP bacteria strains, Serratia marcescens Burkholderia cepacia prepare biogenic silver NPs. The NPs were characterized techniques viz. UV-VIS spectroscopy, SEM, XRD FTIR. AgNPs able control growth phytopathogenic fungi Aspergillus niger, A. fumigatus, Fusarium oxysporum, Pythium sp., Rosellinia sp. more than 80% as examined vitro reduction on agar medium. Very significantly, inhibition seedlings was efficiently rescued using PGP bacteria. These results indicate potential use reduce burden chemical-based pesticides.
