Abstract

                                Colletotrichum lindemuthianum (Saco. and Magn.) Bri. and Cav., which is responsible for the disease known as 'anthracnose affecting french bean (Phaseolus vulgaris. L.), Scarlet runner bean (P. multiflorus L.) Cowpea (Vignacatjang. L.) and Dolichos lablab L.) enjoys wide distribution almost in all countries. But whether the disease on these hosts is due to the same fungus or to different races of it, or to distinct but related species has not been definitely established (Butler and Jones, 1949). In this state anthracnose' of french bean is prevalent on the Nilgiris and the Palnis. In India anthracnose of D. lablab has been reported by Butler (1917). Subramaniam (1953) has described the same from Coimbatore and has identified the pathogen as Colletotrichum lindemuthianum (Glomerella lindemuthianum).
