The present objective of this study was to assess the diversity in isolates, identification and virulence of Colletotrichum capsici from major chilli growing areas in Tamil Nadu, India using the pathogenicity tests under pot culture conditions. Among the major chilli growing areas of Tamil Nadu, the maximum per cent disease index was recorded in Kovilpatti followed by Sattur and Sankarankovil. Whereas, the minimum disease incidence was recorded in Villupuram. Also, the nine isolates of C. capsici collected from various parts of Tamil Nadu exhibited a great variability with respect to mycelial growth, colony colour, colony pattern and Acervuli production. Among the nine isolates, the isolate Cc3 collected from Kovilpatti, Tamil Nadu was significantly the most virulent one which recorded the highest fruit rot intensity and leaves infection.
