An experiment was conducted to know the efficacy of bio agents viz., Purpureocillium lilacinum, Trichoderma harzianum, Bacillus subtilis,Bacillus megaterium, Vermicompost and Consortium of bio-agents (Purpureocillium lilacinum + Trichoderma harzianum + Bacillus subtilis +Bacillusmegaterium +Vermicompost) and Carbofuran3G @ 0.3 i.e., alone for management of rice root-knot nematode Meloidogyne graminicola for one season at Chikadadakatte village of Honnali taluk, Davanagere district during Kharif- 2018. The results revealed that all the treatments were significantly superior over check with respect to growthparameters and nematode population. However, carbofuran 3G significantly reduced the nematode population (275.11 /200 cc soil)which was found to be the best treatment as it recorded highest plant height (114.06 cm), root length (23.13 cm), maximum grain yield (44.60 q/ha) with least RKI (1.20) followed byConsortium of bio-agents (Purpureocilliumlilacinum + Trichoderma harzianum + Bacillus subtilis +Bacillusmegaterium +Vermicompost).
