Abstract: A laboratory experiment was conducted to find out the efficacy of different fungal and bacterial biocontrol agents against cumin wilt pathogen Fusarium oxysporum f. sp. cumini. Among different fungal biocontrol agents tested using dual culture technique, Trichoderma harzianum improved JAU isolate 1 exhibited significantly the maximum inhibition of mycelial growth of F. oxysporum f. sp. cumini (25.22 per cent). Whereas, the least effective biocontrol agent found was Trichoderma koningii (MTCC 2051) with 13.18 per cent mycelial growth inhibition of test fungus in vitro. The antagonistic actions of selected seven bacterial biocontrol agents were evaluated against the test fungus by dual culture technique (ring method). Among different bacterial antagonists, Pseudomonas fluorescens found significantly superior over rest of the biocontrol agents and showed maximum inhibition of mycelial growth of F. oxysporum f. sp. cumini (95.11%). While, the least effective biocontrol agent found was B. subtilis (KT894726) with 47.22 per cent mycelial growth inhibition of test fungus in vitro.
