Abstract: An extensive roving survey carried out during both the year 2017-18 and 2018-19 in the eight districts of Marathwada region for the incidence and intensity of anthracnose of chilli. The disease was found to be predominant in all the eight districts of Marathwada region. Based on symptomatology, cultural and morphological characteristic, pathogenicity test and microscopic observations, the test pathogen was identified as Colletotrichum capsici (Syd.) Butler and Bisby. All the eight representative isolate of C. capsici collected during survey exhibited a wide range of variability in respect of cultural and morphological characters. However, the isolates Cc7 followed by Cc1, Cc2 and Cc3 exhibited maximum mycelial growth of 84.33, 80.90, 75.13 and 68.26 mm, respectively. Maximum conidial size of 25.52 × 2.14 μm was produced by the isolate Cc1 followed by the isolates Cc6 (23.52 × 1.83 μm) and Cc2 (23.12 × 2.85 μm). Maximum growth of C. capsici was recorded on Richard’s agar (88.94 mm) followed by Czapek’s dox agar (88.53 mm), Oat meal agar (87.83 mm), Sabouroud agar (87.31 mm), Beijerinka agar (86.63 mm), and Potato Dextrose Agar (84.37 mm).
