Cercospora beticola Sacc. is a necrogenic pathogene which produces brown small nearly circular spots on the foliage of table beets, sugar beets, mangolds and Swiss chard. On beet leaves the spots have a reddish-purple border, while on mangolds there is usually a pale green border around each spot. The center of the spot is grayish due to long septate conidia produced on conidiophores which come out through the stomata.
