Abstract: Dracaena, is an ornamental plant which helps in air purification. The foliage is damaged by innumerable diseases. Various carbon containing media viz. Potato dextrose agar, Peptone salt agar, Czepek’s Dox Agar, dextrose in Czepek’s Dox Agar medium was replaced by the same amount of sucrose and lactose and Oat meal agar was used to study the radial growth of Colletotrichum fragrans from Dracaena. Among these six carbon media, the most effective medium for its rapid growth was Peptone salt agar medium. Also, the morphological characters differed with change in media constituents, wherein Oat meal agar medium was found to be effective for the production of acervuli, conidia, setae of higher dimensions. Bioassay was conducted using four fungicides viz. Blitox, Mancozeb, Chlorothalonil and Difenoconazole with six different concentrations, Difenoconazole with EC50 value 299.2µ/ml gave best results. Also, in-vivo studies confirmed that Difenoconazole could inhibit the diseased lesion most effectively than others.
