ABSTRACT
Among the fungicides tested, propiconazole and hexaconazole at 0.05 per cent concentration each, provided total inhibition of mycelial growth of A. alternata, while carbendazim, mancozeb, copper hydroxide and propiconazole at 0.1, 0.2, 0.25 and 0.05 per cent concentrations respectively, provided total inhibition of mycelial growth of F. oxysporum f. sp. niveum. Unilife (0.6 per cent) proved most effective bio organics tested against both fungi. Clove extract of garlic (Allium sativum) provided total inhibition of mycelial growth of both fungi. T. harzianum was most promising bio-agent against A. alternata and T. viride was the most effective bio-agent against F. oxysporum f. sp. niveum followed by G. virens. In both cases, T. koningii proved less effective in controlling mycelial growth.
