Experiment was conducted to assess the effect of different bioagents like Trichoderma viride, T. harzianum and Pseudomonas fluorescence and fungicides like Carbendazim (0.1%), Curzate M-8 (0.2%), Topsin M (0.2%), Chlorothalonil (0.2%), Metalaxyl (0.2%), Tridemorph (0.1%), Propiconazole (0.1%), Mancozeb (0.2%), Copper oxychloride (0.3%), Thiram (0.3%), Carbendazim + Mancozeb (0.2%), Tricyclazole + Mancozeb (0.2%) and Zineb + Hexaconazole (0.2%) against Curvularia lunata. After 7th days the T. viride recorded maximum inhibition 60.81% followed with T. harzianum (50.71%) and minimum inhibitory effect was observed in P. fluorescens (33.41%). Among all the systemic non systemic and combination products, Complete inhibition was achieved in tridemorph, propiconazole, dithane, carbendazim + mancozeb, tricyclozole + mancozeb and zineb + hexaconazole and minimum inhibition (10.17%) was recorded in carbendazim 0.1 per cent while 65.33 mm radial mycelial growth was recorded in control.
