Mango anthracnose disease is one of the major fungal diseases of mango. In the present investigation, the rate of growth of Anthracnose (C. gloeosporides) has been compared in various temperature and culture solid media types viz., simple PDA (Potato Dextrose Agar), Oatmeal agar, Nutrient agar, Mango leaf extract agar, Czapek Dox agar. Among all the solid media tested, maximum mycelial growth with excellent sporulation rating was obtained in Potato dextrose agar medium (49.69 mm), which was significantly higher than the other. It was followed by Czapek’s Dox agar (47.83 mm) with good sporulation and oat meal agar (47.29 mm) which were found at par with each. Temperature plays an important role in infection and disease development. Maximum mean colony diameter of fungus was recorded at temperatures of 25°C (48.25 mm) and 30°C (46.17 mm) which was significantly superior over all other temperatures. Lowest mean colony diameter was obtained at temperatures of 15°C (14.54 mm) and 20°C (31.65 mm). Among the four temperature level tested, the optimum temperature for conidial germination of C. gloeosporioides was found to be 25°C followed by 30°C whereas, least growth and germination was observed at 15°C. This is important for further study of disease management.
