Thirty isolates of Colletotrichum falcatum responsible for red rot of sugarcane were isolated from seven sugarcane varieties from different localities during 2018–2019 and the resulting cultures were maintained on suitable media. Length of conidia ranged from 10 to 30 μm, while width from 4 to 12 μm. The conidia of all isolates were falcate shaped with hyaline colour at the base. On cultural media, growth of fungus was in the form of colony having 60–90 mm diameter. The colonies exhibited various colours viz., greyish, greyish white, white orange and white brown. The margin of the colony was smooth and irregular. All isolates were with well sporulation. The isolates from different region of Maharashtra and Karnataka were, however, culturally and morphologically dissimilar with respect to their mycelial growth, conidial size as well as colour and texture of the colonies.
