INTEGRATED MANAGEMENT OF FOOT AND ROOT ROT DISEASE OF BETELVINE (Piper betle L.) CAUSED BY Sclerotium rolfsii

Piper betel or Betelvine leaves called Pan belongs to the family Piperaceae. Leaves are rich in many nutrients like water, energy, protein, fats, fiber, calcium and iron etc. and the antioxidants and used for chewing in Bangladesh. The foot and root rot caused by Sclerotium rolfsii is the most devastating disease that decreases the production of betel leaf. The betelvine growers have no sustainable approach for controlling the disease to increase production. The objective of the study was to find out the integrated effect of integrated pest management components for the management of foot and root rot disease of betelvine caused by S. rolfsii. The experiment was conducted in a betelvine orchard (Baroj) under field condition. The integrated application of nine IPM components in 22 treatment combinations including an untreated control were evaluated under inoculated conditions to control foot and root rot of betel vine caused by Sclerotium rolfsii. Efficacy of as integrated approach application of either Provax 200 (0.25%) or Score 250 EC (0.05%) or Garlic clove extract (1:1 w/v) (15% concentration) in combination with soil application of Trichoderma harzianum (5g of culture in barley grain) or Vermi-compost (30g per plant) was found as the suitable approach for the management of foot and root rot disease of betel vine that reduced up to 100% disease incidence increasing yield up to 82.78% over control. So, the integrated effect of IPM components, soil drenching with either garlic clove extract or Provax 200 or Score 250 EC in combination of soil amendment with T. harzianum or Vermi-compost are recommended the promising performances for the eco-friendly management of foot and root rot disease of betelvine.
