Abstract : The maximum growth of the pathogen Botryodiplodia theobromae was observed at 25°C, while there was no growth at 0, 5, 10 and 40°C. The maximum mycelial weight and pycnidial production were recorded at pH 6.5 followed by pH 6.0. Among the carbon sources, sucrose and glucose encouraged the growth of B. theobromae (81.66 and 84.00 mm, respectively). The pathogen showed noticable pycnidia formation in mannitol and maltose substituted media. Among the nitrogen sources, potassium nitrate recorded higher growth (90.00 mm colony diameter) than other nitrogen sources.
