Anthracnose incited by various species of Colletotrichum causes huge yield losses to beans. Cultural and morphological characteristics of Colletotrichum sp. from field bean, French bean, cowpea, mungbean, urdbean, soybean, horsegram, clusterbean, swordbean, wingedbean, yard longbean and pillipesara were studied in vitro on Potato Dextrose Agar. Variations were noticed with respect to colony colour and shape of conidia. Pathogenicity of these isolates was proved on their respective native hosts and cross pathogenicity varied from different test plant species. Among the test plant species, cowpea, horsegram and mungbean showed the positive reaction to the C. lindemuthianum and C. truncatum isolates, while clusterbean showed host specificity.
