An investigation was carried out to assess the efficiency of Pseudomonas flourescens (PGPR) and Heterorhabditis indica Poinar (Entomopathogenic Nematode) against major rice pests. Rice seedling dip plus spraying in the main field @ 15g/litre with P. flourescens was found to be significantly effective in reducing the incidence of stem borer (Scirpophaga incertulas). Spraying of H.indica @ 3000 IJs /ml was effective in reducing the white ear incidence. The incidence of gall midge (Orselia orzae) was significantly reduced with the treatment of P. flourescens seedling dip plus spray @ 10g/litre. EPN spray @ 2500 IJs /ml was also equally effective in reducing the gall midge incidence at 25 DAT. Case worm (Paraponyx stagnalis) damage was observed to be lowest in plots treated with P. flourescens seedling dip plus spray @ 15g/litre. Treatment with H. indica indicated a lowest incidence of leaffolder (Cnaphalocrocis medinalis). H. indica applied @ 3000 IJs/ml was the superior treatment at 25 days after transplanting while at the later stage (55 days after transplanting), a lower dose @ 2500 IJs /ml was found to be sufficient to bring about significant control of leaffolder. The incidence of P. stagnalis was significantly lowest with P. flourescens seedling dip plus spray @ 15g/litre. But the treatments showed no significant difference against the incidence of blue beetle (Leptispa pygmaea) and whorl maggot (Hydrellia phillippina).
