The test antagonists Trichoderma spp. and Pseudomonas spp. were tested against test pathogen Rhizoctonia solani and they were grown on the same plate to test the antagonistic activity. About 15 to 20 ml of melted and cooled PDA medium. and the King’s B medium was poured in to Petri plates and allowed to solidify. Fungal disc of the antagonist of was placed at one end of media on Petri plate. In dual culture test, maximum inhibition in radial growth of Rhizoctonia solani was obtained with Trichoderma viride (67.60 %) followed by Trichoderma harzianum (60.00%). Pseudomonas spp. was also inhibited the radial growth of Rhizoctonia solani by (70.40%).
