Eight strains of Psuedomonas fluorescensviz., Pf1, Pf2, Pf3, Pf4, Pf5, Pf6, Pf7 and Pf8 were tested
for their efficacyagainst mortality of J2 of Meloidogyne incognitaassociation with wilt complex in
pomegranate. Among eight strains, Pf3 recorded the 78.00 per cent mortality of M. incognita J2 at
an exposure time of 120 hours followed by Pf1 (68.33%), Pf4 (62.00%) and Pf8 (54.33%), Pf6
(50.67%) were on par with each other at 100 per cent concentration. Minimum mortality of second
stage juvenile were observed in Pf2 (40.67%) at 100% concentration at an exposure period of 120
hours, followed by Pf5 (48.00%) and Pf7 (49.00%). All the bioagents evaluated had caused
mortality of M. incognita J2 with 50%, 75% and 100% concentration in comparison to the control
