Abstract : Anthracnose caused by Colletotrichum gloeosporioides (Penz.) Penz. and Sacc. is one of the most damaging diseases causing losses in pre and post harvest conditions in mango. Studies were conducted to find out the favourable temperature, relative humidity and light period for the growth and conidial germination of C. gloeosporioides under in vitro condition. The study indicated that the temperature of 25°C was found to be good for the mycelial growth (89.6 mm) and conidial germination (69%). At 100% relative humidity, the mycelial growth (90 mm) and conidial germination (87%) were higher. In this context, different light periods were tested, continuous light favoured the both mycelial growth and conidial germination.
