Abstract: Leaf blight of cardamom incited by the fungal pathogen <em>Colletotrichum gloeosporioides</em> (Penz.) has become a major and wide spread leaf disease in major cardamom growing regions of South India. Attempts were made to find out the best suitable fungicide for the management of leaf blight of cardamom in arecanut based intercropping system. Among the fungicides tested combination fungicide SAAF (carbendazim + mancozeb) @ 0.2 % and carbendazim @ 0.1 % are found to be more effective in cardamom leaf blight disease management fallowed by hexaconazole. The plants treated with SAAF (carbendazim + mancozeb) were consistently recorded less disease intensity consecutively for three years. Other fungicides propeconazole and difenconazole did not show better performance compared to SAAF (carbendazim + mancozeb) and carbendazim. The information generated from the study is useful in formulating effective and economical method of disease management.
