Abstract:
Seven fungicides and four biocontrol agents were evaluated In vitro for their efficacy against virulent isolate (BDN Foc-04) of Fusarium oxysporum f. sp. ciceris causing wilt in chickpea. Carbendazim 50% wp was found the most effective with completely (100 per cent) inhibition the mycelial growth of F. oxysporum at all concentrations (100, 500 and 1000 ppm) followed by Saaf (Carbendazim 12% + Mancozeb 63% WP) was found effective with 70.00, 78.67 and 84.89 percent mycelial growth inhibition at 100, 500 and 1000 ppm respectively. Among all tested antagonist viz Trichoderma viride (T.v.-5), T. harzianum (JH. h. 89-2), T. aureoviride (DG.a.91-5), and T. viride (PCI- Banglore) by dule culture method Trichoderma viride (T.v.-5), found most effective with 73.6 percent mycelia growth inhibition.
