Pomegranate is an important commercial fruit grown worldwide. The productivity of pomegranate is hampered by different diseases, among them anthracnose is one of the important disease caused by Colletotrichum gloeosporioides. Therefore, for better understanding of the nature of the pathogen cultural studies carried out. In cultural studies on different solid media, maximum radial growth of the fungus (87.5 mm) was recorded on malt extract agar, while sporulation was excellent in the case of malt extract agar which was at par with oat meal agar and potato dextrose agar medium. Colony growth varies from flat to fluffy with regular to irregular margin and pigmentation varies from white or yellow or orange. In growth phase study the maximum dry mycelial weight of C. gloeosporioides was observed on 12th days of incubation on potato dextrose broth (451.9 mg).
