Abstract:
Among the various diseases of sunhemp, fusarium wilt is causing severe loss to the sunhemp production. Managing Fusarium wilt in sunhemp is challenging because the pathogen can persist in the soil as chlamydospores for several years, even in the absence of the host plant. Consequently, fungicides have become a crucial tool in managing this disease. Assessing the efficacy of fungicides against Fusarium wilt in sunhemp is vital for developing effective disease management strategies. Hence, In vitro and in vivo evaluation of fungicides were carried out in our study. Studies on In vitro evaluation of fungicides revealed that, mancozeb among contact fungicides, tebuconozole among the systemic fungicides and carbendazim 12% + mancozeb 63%) WP and (carboxin 37.5% + thiram 37.5%) WP from the combi group were found effective with cent per cent inhibition of mycelial growth of the pathogen. Management of fusarium wilt of sunhemp under field condition revealed that, seed treatment with (carboxin 37.5% + thiram 37.5%) @ 3 g/kg + soil drenching of (carboxin 37.5% + thiram 37.5%) @ 0.2% or ST with tebuconozole 2% DS @ 2 g/kg + soil drenching of tebuconozole 250 EC @ 0.1% were found effective in reducing the disease incidence with maximum yield. As per B:C ratio, seed treatment with (carboxin 37.5% + thiram 37.5%) WP @ 3g/kg of seeds recorded highest B:C ratio of 2.84 and was found best.
