Cross Inoculation Studies of Colletotrichum capsici Isolates between Betelvine, Turmeric and Chilli

Colletotrichum capsici causes chilli anthracnose and has a wide host range betel vine, turmeric, bitter gourd, castor, cluster bean, cotton, marigold etc. Cross inoculation studies were made on three important horticultural crops, betel vine, chilli and turmeric. In all the three hosts (chilli, turmeric and betelvine) the mean lesion size (mm 2 ) produced by the isolates from the original host were higher compared to isolates from non hosts. Isolates also differed in their virulence levels and C. capsici isolated from turmeric is more virulent compared to other isolates. Isolates differed in the days for chlorotic and necrotic symptoms. C. capsici isolates exhibited host preference among the three hosts. Turmeric is more preferred host for C. capsici compared to betelvine and chilli.
