Incidence and Pathogenicity of Didymella americana on Table Beet in New York

N. Vaghefi, J. R. Kikkert, and S. J. Pethybridge

January 2017


New York is the second largest producer of table beet (Beta vulgaris ssp. vulgaris) in the United States. In 2015, a Didymella sp. was isolated from table beet fields across New York. Foliar symptoms included dark sunken spots, large necrotic patches with indefinite margins, and necrotic, round-to-oval lesions. The objective was to identify the Didymella sp. associated with table beet, and assess pathogenicity.
