Bio-Agent induced systemic resistance in rice (Oryza Sativa L.) against sheath blight caused by Rhizoctonia solani Sathya R1, Devi P. Ahila1, Rajappan K.1 Tamil Nadu Rice Research Institute, Aduthurai, Thanjavur District-612 101 1National Pulses Research Centre, Vamban, District Pudukottai-622 303 Online published on 27 August, 2019. Abstract Isolates P. fluorescens showed positive results. When it wasapplied as seed treatment @ 10 g/kg of seeds, seedling root dip @ 2 g/l, soil application @ 2.5 kg/ha and foliar spray @ 5 g/l (T3) at 30 and 45 DAT recorded least disease severity, with 9.58 per cent increase in the yield. Foliar application of P. fluorescens on R. solani inoculated plants showed increased activities of Peroxidase, Poly phenol oxidase, Phenyl alanine ammonia-lyase, phenolic content and ß 1, 3-glucanase.
