摘要：

A previously unreported anthracnose disease incited by Colletotrichum truncatum was discovered on hemp sesbania seedlings in Washington County, Mississippi, in 1987. Hemp sesbania inoculated with 2 x 10(7) spores per milliliter in the greenhouse were killed within 7 days. Soybean cvs. Bragg, Bedford, and Hill developed small, necrotic leaf spots, but no further symptoms occurred after 3 wk. Several cultivars of cotton, rice, and 23 other plant species representing eight plant families were immune to disease, as measured by visual assessment. Results of these tests indicate that this fungus has potential as a mycoherbicide to control hemp sesbania.
