Black mold and Fusarium base rot of onion is caused by Aspergillus niger and Fusarium oxysporum f.sp.cepae are the most destructive diseases of onion in storage causing accountable losses of about 80 per cent and more than 50 per cent respectively. The fungicides, evaluated in vitro were found fungistatic/antifungal against both pathogen. In A. niger the most effective fungicides with significantly highest mycelial growth inhibition were SAFF (94.55 per cent), carbendazim (92.22 per cent) and mancozeb (90.98 per cent). The bioagents viz., T. viride (85.61 per cent) and T.harzinum (82.19 per cent) were found potential antagonists against A.niger. In Fusarium oxysporum f.sp.cepae fungicides viz., hexaconazole, SAFF, mancozeb and carbendazim were found most effective with significantly highest mycelial growth inhibition of 91.73 per cent, 91.39 per cent, 90.82 per cent and 88.42 per cent respectively. The bioagents viz., T. viride (88.1 per cent) and T. harzianum (81.55 per cent) recorded significantly highest mycelial growth inhibition.
