Attempts were made to determine the effect of leaf extracts of Azadirachta indica, Ocimum sanctum, Tridex procumbens, Clerodendron innermis, Cathranthus roseus, Ricinus communis, Citrus limon against Colletotrichum capsici. Out of these medicinal plants tested, 15% alcoholic extract of Azadirachta indica and O. sanctum was found inhibitory for the growth of Colletotrichum capsici. The results show that extracts from leaves of different plants vary in their effects on growth of C. capsici. It is evident from the results that aqueous and alcoholic leaf extracts of A. indica and O. sanctum exhibited strong fungitoxicity against C. capsici. Alcoholic extract of all the seven plants showed significant result as compared to aqueous extracts.
Key words: Chilli, anthracnose, leaf extract, Colletotrichum capsici.
