Development of bio-rational management package for fusarium wilt and sigatoka disease of banana

Abstract

Efficacy of different bio-rational based fungicides was studied at the Regional Horticulture Research Station, Bangladesh Agricultural Research Institute, Shibpur, Narsingdi during the period of April, 2021 to May, 2022 to find out the effective management package(s) against Fusarium wilt and sigatoka diseases of banana. Four treatments combinations were compared with the farmer’s practices (control where no fungicide) under natural epiphytotic conditions. Among the tested treatments, T₄ = Decoprima (5g/pit) + Soil recharge (5g/pit) + Alternate foliar spray with Dynamic (2g/pit) and Tilt 250 EC (0.5ml/litre of watre) displayed maximum reduction of Fusarium wilt disease incidence (100%) at 180 days after planting (DAP). In case of sigatoka, the highest disease severity of 26.67 % was recorded in T₅ (Farmers practices) treated plants at 180 DAP and the lowest in T₄ treated plants where severity was 10%. The highest banana fruit yield (11 kg per bunch) was obtained from T₄ treated plants while the lowest yield (6.40 kg per bunch) in T₅ treated plants.
