SUMMARY Out of 1200 autumn‐lifted carrots (Daucus carotd) , stored for 40 days at 4–6 ° C in the laboratory, twenty‐seven developed lesions caused by Botrytis cinerea ; of these primary lesions, twenty‐three occurred in the crown. Similar lesions were observed on the crowns of field‐stored carrots whether or not they were protected from frost damage by strawing over. The fungus was isolated from lesions on the foliage and petiole bases of freshly harvested carrots throughout the storage season. All such isolates proved to be pathogenic to roots at storage temperatures. Carrots may thus enter storage with an incipient infection, which may develop into a crown rot and spread to adjacent healthy roots by hyphal growth.
