Abstract An investigation was carried out with the aim to study the interactive effect of Pseudomonas fluorescens(PF9) and Rhizophora apiculata for the management of bacterial leaf blight disease of rice. In both pot andfield trials, application of P. fluorescens as seed treatment (10 ml/kg seed) and foliar spray of R. apiculata @15% at 35 and 50 DAT significantly reduced the bacterial leaf blight incidence with maximum plant height,number of productive tillers per hill, panicle length, grains per panicle of paddy and recorded on par resultswith that of streptomycin (100 ppm) treatment. Untreated control treatment recorded the maximum per centdisease incidence and minimum plant height, number of productive tillers per hill, panicle length as well asgrains per panicle of rice.
