Abstract

RChilli anthracnose caused by Colletotrichum truncatum is the major fungal foliar pathogen causing havoc inproduction, export and marketing. A study was conducted on cultural and morphological characterization of the pathogenunder in vitro condition. Among the media, the radial growth ranged from 38.00 to 90.00 mm, maximum radial growth wasrecorded in Czapek’s dox agar (90.00 mm) and lowest growth was seen in Czapek’s malt agar (38.00 mm). Colour of thecolony varied from white, dull white, grey and dull white to grey. The colony texture varied from smooth to coarse and themargin varied from regular to irregular. The sporulation varied from moderate to good. Good sporulation was recorded incorn meal agar, Czapek’s dox agar, potato carrot agar and potato dextrose agar.
