Mango is regarded as ‘king of fruits’ and is grown mainly in tropical and subtropical regions of the world. Anthracnose is one of the devastating disease, known to cause yield loss from 10 to 80 per cent in orchard and also being post-harvest disease, it cause an economical loss to the tune of 15-20 per cent. The disease is caused by the fungal pathogen Colletotrichum gloeosprorioides. Information on the cultural and physiological requirements of the pathogen will aid in formulating the effective management stratergy. Among the ten solid media tested, maximum radial growth of the pathogen was observed in potato dextrose agar (88.23 mm) followed by Sabouraud’s agar (78.33 mm) and the least radial growth was recorded in host leaf extract agar (57.09 mm). Sporulation of the fungus was found to be abundant on Richards’s agar, least in host leaf extract agar and no sporulation in V-8 juice agar. Under physiological requirements of the pathogen temperature of 25 oC accompanied with relative humidity of 95 per cent were found optimum for the maximum growth of the pathogen.
