Anthracnose caused by Colletotrichum sp. is a major disease of betelvine under humid cultivation conditions. The present investigation was conducted to study the physiological and nutritional requirements of the pathogen and to evaluate effective management strategies under in vitro conditions. Among the solid media tested, Oat meal agar supported maximum mycelial growth (45.16 mm at 3 days and 79.66 mm at 6 days) with excellent sporulation, followed by Potato dextrose agar, while minimum growth and no sporulation were observed on Sabouraud’s dextrose agar. Optimum fungal growth was recorded at 25°C, pH 7.5 and 95–100% relative humidity. Glucose and maltose were the most suitable carbon sources, whereas potassium nitrate and ammonium nitrate supported maximum growth among nitrogen sources.
