Finger millet is an important food crop that is grown in arid and semi-arid parts of Africa and Asia and it serves as a staple food source for millions of people. Blast is the most devastating disease affecting it at every stage of growth and development. In recent years, endophytes received attention because of their potential to increase crop yield without massive application of synthetic chemicals. Landraces are traditional, regional ecotypes that have adapted to their natural environment, some possess resistance to the blast disease. In this study, 42 bacterial endophytes were isolated from fifteen landraces and were screened for their antagonistic activity against Pyricularia grisea, causal agent of finger millet blast. Seed constitutes high number of bacterial colonies with the landrace, thenemundaga ragi. The isolates HMS-1 (91.04%), GPRS-1 (92.54%) and GPRR (92.54%) were efficient in inhibiting the pathogen growth in both dual culture plate and biomass assay by means of antibiosis and hyper parasitism. Hence, one can explore the microflora of these landraces and can utilize them as best microbial inoculants for management of blast disease, to improve plant growth and crop yield.
