Colletotrichum is one of the most important plant pathogens worldwide causing the economically important disease anthracnose in a wide range of hosts including cereals, legumes, vegetables, perennial crops and tree fruits. Among these hosts, chilli (Capsicum spp.), an important economic crop worldwide, is severely infected by anthracnose which may cause yield losses of upto 50 per cent. Typical anthracnose symptoms on chilli fruit include sunken necrotic tissues, with concentric rings of acervuli (Manandhar et al., 1995). Fruits showing blemishes have reduced marketability. During March-April, 2012 very high disease incidence (upto 100% of plants) was observed in farmer’s fields in KannamangalamSaveriyarpuram village in Illayankudi block in Ramnad district.

Abstract


Colletotrichum is one of the most important plant pathogens worldwide causing the economically important disease anthracnose in a wide range of hosts including cereals, legumes, vegetables, perennial crops and tree fruits. Among these hosts, chilli (Capsicum spp.), an important economic crop worldwide, is severely infected by anthracnose which may cause yield losses of upto 50 per cent. Typical anthracnose symptoms on chilli fruit include sunken necrotic tissues, with concentric rings of acervuli (Manandhar et al., 1995). Fruits showing blemishes have reduced marketability. During March-April, 2012 very high disease incidence (upto 100% of plants) was observed in farmer’s fields in KannamangalamSaveriyarpuram village in Illayankudi block in Ramnad district.
