First report of crater rot caused byRhizoctonia carotaeon carrots (Daucus carota) in Turkey.

The article reports the occurrence of crater rot caused by Rhizoctonia carotae on carrots in Turkey. Primary symptoms seen were a band of dark brown necrosis around the carrot crown and horizontal, brown, canker-like lesions, mostly on the crown and upper roots. Small pits subsequently developed beneath the lesions, which enlarged into sunken brown crater lines with a white, flocculent mycelium produced under high humidity. Fungal colonies were initially white, but turned brown with age. Dark brown to black sclerotia were occasionally produced.
