Papaya is prone to many diseases incited by fungi, bacteria, nematodes and viruses leading to enormous loss in yield. Among all, papaya anthracnose incited by Colletotrichum gloeosporioides (Penz.) Penz. & Sacc. appear to be more severe causing substantial losses to papaya fruits during transit and storage. Papaya anthracnose is the most important disease throughout the year in India and it became a major limiting factor in papaya cultivation. Total nineteen isolates of Colletotrichum spp. studied for their cultural characters at 2nd, 4th, 6th and 8th day after incubation. Significantly highest mycelial growth of Colletotrichum spp. after 4 days was recorded in isolate Cd-8. After 8th day of incubation, significantly highest mycelial growth was recorded in isolates Cd-13 and Cd-15 (90.00 mm). Significantly highest length and breadth of conidia were recorded in an isolate Cd-13 (26.97 & 5.57 µm) and Cd-8 (25.40 & 5.33 µm) as compare to other isolates. Significantly maximum number of setae per acervulus was recorded in isolate Cd-13 (32.00) over all other isolates.
