Soybean [Glycine max (L.) Merrill.] is an important oilseed crop. Colletotrichum truncatum, the incitant of anthracnose/ pod blight in soybean is one of the most destructive pathogens. Eight fungicides (@ 500, 1000, 1500, 2000 and 2500ppm each), 10 botanicals@ 10% and four bioagents were evaluated in vitro against C. truncatum, using PDA as basal medium. The results revealed that all the fungicides, botanicals and bioagents tested were found fungistatic and significantly inhibited the mycelial growth of the test pathogen over untreated control. Among the fungicides, Carbendazim + Mancozeb and Propiconazole recorded the highest mean inhibition (100 %) of mycelial growth of the test pathogen, followed by the fungicide, tebunconazole inhibited 100 per cent inhibition at concentration of 1500 ppm. Least inhibition was observed in hexaconazole at 500 ppm concentration. Among ten botanicals tested, Garlic extract recorded highest mean mycelial growth inhibition (53.22%) of the test pathogen followed by the onion extract (47.11%), neem (46.44%).Vavilaku extract (9.7%) was found to be the least effective in inhibition of mycelial growth of pathogen. Among the bioagents, T. harzianum recorded highest mean mycelial growth inhibition of 80.22 followed by T.viride (72.55%).
