Abstract
At the United States Department of Agriculture Sugar Plant Investigations, Meridian, Mississippi, the author studied the pathogenicity to sugar-cane and sorghum of 593 isolates of Colletotrichum from 18 grass species, of which 563 were collected on sugar-cane, sorghum, Johnson grass [Sorghum halepense]. Sudan grass, broomcorn [S. bicolor var. technicus]. and Erianthus. Pathogenicity was judged by the capacity of the isolates to induce red rot in cut sugar-cane and sorghum stalks and leaf spot in sorghum following leaf whorl inoculations. The two methods, yielded comparable results. Three species of Colletotrichum have been described as occurring on different grasses, namely, C. falcatum [Physalospora tucumanensis [Glomerella tucumanensis]]. the agent of red rot of sugar-cane, C. lineola, and C. cereale, of which the two last-named were referred by G. W. Wilson (Phytopathology, 4, pp. 106-112, 1914) to a single species, C. graminicola. In these experiments the isolates fell into three groups on the basis of pathogenicity to sorghum and sugar-cane. Cultures isolated from sugar-cane formed a group which caused severe damage to the same host but rarely attacked sorghum, while those originating on sorghum, S. halepense, Sudan grass, S. bicolor var. technicus, and Erianthus were non-pathogenic to sugar-cane but mostly highly pathogenic to sorghum. Neither sorghum nor sugar-cane sustained any material damage from a third group of 28 isolates from 13 other grasses.
