The present researches were carried out to differentiate the species of Colletotrichum by elecrophoretic method. C. gloeosporioides, C. dematium and Gloeosporium fructigenum could be differentiated by the isozyme patterns of esterase, leucine aminopeptidase, acid phosphatase and glutamic oxaloacetic transaminase. Especially. G-strain and R-strain of C. gloeosporioides were differentiated by the enzyme patterns. The G­strain damaged all stage fruits (green and red fruits) of Capsicum annum. The R-strain could not infect the unripe (green) fruits, but it could damage only ripe (red) fruit of Capsicum annum.
