Abstract

Late leaf spot incited by Cercosporidium personatum is the serious disease in groundnut. The effect of different methods of application of Pseudomonas fluorescens (Pf1) in managing late leaf spot of groundnut was assessed under greenhouse condition. Among the different methods tested, seed treatment coupled with foliar application of Pf1 formulation was found to be the most effective in managing late leaf spot disease. The boosting effect of Pf1 formulation on plant growth was evidenced by the fact that the plant height, leaf area index, root length, nodules per plant and dry matter production were the maximum in P. fluorescens treated plants. Pod yield was also found to be increased by using Pf1. Seed treatment followed by foliar application of Pf1 formulation gave the maximum pod yield
