Anthracnose of kartoli (Momordka dioica) in Konkan region of Maharashtra

摘要

The fungus producing typical anthracnose like symptoms was isolated and the pathogenicity tests were confirmed. The fungus identified as Colletotrichum lagenarium (Pass.) Ellis and Halsted produced cottony growth with pinkish conidial masses and acervuli in the form of raised black bodies on colony surface. The pathogen could infect snapmelon, cucumber, watermelon, snake gourd, bitter gourd and bottle gourd but was non-pathogenic to pumpkin, sponge gourd, ridge gourd and little gourd from cucurbitaceous family and some noncucurbitaceous crops viz. tomato, chilli, brinjal, okra, groundnut, dolichos bean, cowpea and amaranthus. Bordeaux mixture, copper oxychloride, carbendazim and thiophanate were promising in inhibiting the mycelial growth of the fungus in vitro.
