Abstract: Bean anthracnose caused by Colletotrichum lindemuthianum (Sacc. and Magn.) is an important seed borne disease throughout the world. This pathogen overwinters on bean seed hence the losses can be 100%. Three fungicides alone namely Hexaconazole, Captan, Carbendazim and three in combinations i.e. Hexaconazole + Bacillus ceresus, Captan + Trichoderma harzianum and Carbendazim + Pseudomonas fluorescens were used at different concentrations (100, 250, 500 and 750 ppm) by poisoned food technique. Alone Carbendazim and in combination, Carbendazim + P. fluorescens found complete inhibition of C. lindemuthianum at 100 ppm, while Captan at all concentration (52.48, 62.27, 68.05 and 69.75%) and in combination Hexaconazole + B. ceresus (53.30, 63.98, 80.89 and 81.77%) were found minimum inhibition. Three bio control agents viz. B. ceresus, T. harzianum and P. fluorescens were evaluated by dual culture technique, to check their antagonistic effect on the growth of C. lindemuthianum. Among bio agents T. harzianum observed (73.87%) maximum mycelium growth inhibition while B. ceresus minimum (31.33%).
