First report of the anthracnose fungus Colletotrichum musicola (Sordariomycetes: Glomerellales) infecting Glycine max (soybean)
Source: Plant Disease
Event:  New Host

In 2016 and 2017, cultivated Glycine max (soybean) plants in Brazil exhibited necrotic, irregular lesions on stems, leaves, and pods. Morphological and molecular analyses, as well as fulfillment of Koch’s postulates, confirmed that the causal agent was the anthracnose fungus Colletotrichum musicola (Sordariomycetes: Glomerellales). Pathogenicity tests confirmed that Colletotrichum musicola is seed-borne. This is the first report of Colletotrichum musicola infecting G. max.

Colletotrichum musicola also infects Musa sp. (banana), Colocasia esculenta (taro), and Phaseolus lunatus (lima bean). Colletotrichum musicola has been reported from Brazil and Mexico and is not known to occur in the United States. The PEST ID database lists the genus Colletotrichum as reportable (queried 2/26/20).
