Survey on the disease in the field showed the extent of Cercospora leaf spot disease affecting the crop and quality of the leaves in different locations which was widespread particularly in intermitted rainy season / high moisture conditions, cloudy weather and incidence and severity of disease was more in Chikamagalur district followed by Davanagere and Shivamogga districts. Among the tested fungicides, in vitro hexaconazole, carbendazim were superior, in inhibiting the mycelial growth of the fungus. Where as in vivo carbendazim,  hexaconazole and propiconazole at 0.1 per cent were found effective in managing the disease and recorded higher yield of 11.86, 7.92 and 6.96 tons per ha respectively.
