Abstract

An investigation was carried out in vitro to evaluate the antagonistic effect of fungal bio-control agents i.e., Trichoderma harzianum, T. viride, Purpureocillium lilacinum, Metarhizium anisopliae and Beauveria bassiana on second stage juvenile (J₂) mortality of root-knot nematode (RKN) at 10⁶ and 10⁷ dilutions on juvenile mortality of M. incognita after 24, 48, 72, 96 and 120 hrs exposure period as compared to untreated check. Among different dilutions, T. viride at 10⁶ dilutions (86.00 per cent) gave maximum per cent juvenile mortality followed by T. harzianum at 10⁶ dilutions (82.00 per cent), P. lilacinum at 10⁶dilutions (76.00 per cent) and T. viride at 10⁷ dilutions (72.00 per cent) after 120 hrs. M. anisopliae at 10⁷ dilutions (38.00 per cent) was found least effective at different period of exposure.Further studies need to be conducted in pot and field conditions to evaluate the efficacy of these bio-agents against root knot nematode, M. incognita.
