Curvularia lunata is a soil-borne fungal pathogen that attacks rice and causes significant losses in its production, while Pseudomonas fluorescens is one of the common biocontrol agents used for managing foliar infection in soil born pathogen. The aim of this research was to study the effect of Pseudomonas fluorescens as biocontrol agent against Curvularia lunata on rice variety Gawal r1. The isolate were tested for pathogenicity. In a pot experiment, P. fluorescens significantly reduced the disease severity of rice blight caused by C. lunata. After application of a spore suspension of Pseudomonas fluorescens -biofungicide and Synthetic fungicide (Mancozeb) to rice seedlings inoculated with C. lunata, the disease severity was reduced by 2.00, 2.55, 3.2, and 4.66, respectively. In Screen house trial, the concentrations Pseudomonas fluorescens concentrations at 3.0 × 108 CFU/ml gave the best results in all plant parameters, as compared to the inoculated control with C. lunata.
