Rhizobacterial isolates were investigated for biocontrol efficacy against bhendi yellow vein mosaic virus (BYVMV) in bhendi plants. Bioformulations of rhizobacteria applied to seed, soil and foliage significantly reduced BYVMV, with a concomitant increase in plant growth and fruit yields under glasshouse condition. Of all the rhizobacterial isolates evaluated, fluorescent Pseudomonas 218 (1) was the most effective strain. It reduced the incidence of BYVMV to the maximum extent (up to 86.6 per cent), through induced systemic resistance by triggering defense molecules. Biosynthesis of peroxidase and PALase were improved by 79 and 47 percent respectively over the diseased control.
