Two field experiments were conducted with tomato Hybrid 5005 at Kuttathottam and Theethipalayam villages of Coimbatore district to investigate the potential of two promising native isolates of plant growth promoting rhizobacteria (PGPR), viz., Pseudomonas fluorescens (Pfbv22) and Bacillus subtilis (Bbv57) for the management of ischolar_main knot nematode Meloidogyne incognita and reniform nematode Rotylenchulus reniformis in tomato. The biocontrol agents were compared with the standard chemical viz., carbofuran. Consortium application of P. fluorescens (Pfbv22) and B. subtilis (Bbv57) as seed treatment each @ 5 g kg-1 seeds and soil application (SA) @ 1.25 kg ha-1 significantly reduced the nematode infestation in soil and ischolar_main. The microbial consortium treatment also significantly enhanced the plant growth parameters such as plant height, shoot weight, ischolar_main length, ischolar_main weight and fruit yield.
