STORAGE DISEASES OF CARROTS, ESPECIALLY RHIZOCTONIA CRATER ROT

In 1934 Ramsey reported a disease which occurred in a cold storage in New York State, USA, and which must be the same as the one discussed here.
Because of rather severe attacks in 1940’s in the same state, Rader investigated the disease and isolated a fungus which he named Rhizoctonia carotae n.sp.; he named the disease Rhizoctonia crater rot.

Since 1952 (Rader) there seems to have been very little published about Rh. carotae and the typical disease symptoms.
Mukula (1957) did not find Rh. carotae in his comprehensive investigations of storage diseases of carrots in Finland, and besides the above mentioned occurrence in USA the disease only seems have been observed in Denmark (Jensen 1967 and 1969) and in Norway (Arsvoll 1968).
