Abstract

Abstract The application of talc-formulation through seed, seed treatment plus foliar spray and foliar spray alone significantly reduced the leaf blight incidence both under greenhouse and field conditions. The groundnut plants treated with biocontrol agent and challenge inoculated with Alternaria alternata recorded significantly increased activity of Peroxidase isozyme (PO), Polyphenol oxidase isozymes (PPO) activity. Expression of PO2, PPO1 and PPO2 isoforms were found in all the plants treated with Pf1 while additional PO1, PPO3, PPO4 and PPO5 were observed in Pf1-treated plants followed by challenge inoculation with the pathogen.
