Abstract
The present investigation was carried out to study the effect of integrated use of propiconazole and bacterial bio control agents (Pseudomonas fluorescens and Bacillus subtilis) on the incidence of rice (Oryza sativa L) brown leaf spot during 2020-2021 at Annamalai University, Chidambaram. Among the various treatments tested in pot culture, seed treatment with consortia of P. fluorescens and B. subtilis + 1st foliar spray with Consortia of P. fluorescens and B. subtilis at 45 DAT + 2nd foliar spray with Propiconazole 25% EC at 60 DAT (T7) recorded minimum disease incidence (7.45%) and maximum number of productive tillers/ clump (17), grain (76.0 g/pot) and straw (127 g/pot) yield. In field studies also T7 treatment produced least disease incidence of brown spot (8.50%) and maximum growth parameters (17 productive tillers/clump) grain (74 qha-1) straw (86.30 qha-1) yield. Per cent disease incidence increased regularly with age of the crop, irrespective of treatments and maximum values were recorded at harvest. The maximum disease incidence and minimum values of growth and yield of rice recorded under control in both pot culture and field condition.
