Carrot cercospora leaf blight (Cercospora leaf spot of carrots)
Cercospora carotae
Cercospora infections can occur along the leaf margin, but spots are elongated and cause the leaflet to curl. Spots not on the margin are circular. Spots are at first small chlorotic flecks that become larger and tan, brown, or black with a necrotic center surrounded by a yellowish border. Commonly, spots coalesce and, subsequently, the leaves curl.
