Abstract
Abstract A description is provided for Xanthomonas campestris pv. corylina . Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Corylus avellana, C. maxima and C. rostrata (syn. C. californica ). On inoculation C. colurna is also infected. DISEASE: Bacterial blight or bacteriosis of filbert or hazel nut trees. Leaf spots, bud and twig necroses and stem cankers are produced. The cankers may girdle branches or even trunks of young trees and cause death above. GEOGRAPHICAL DISTRIBUTION: Turkey (Black Sea area 54, 578), Australia (Vict. 60, 6677), England (59, 3913), France (56, 86), Italy (64, 4520), Yugoslavia (37: 125), USA (OR, WA), Chile (culture received at CMI), and apparently USSR (58, 4044). TRANSMISSION: Bacteria overwinter in cankers on branches and in buds, and spread to other parts of the tree in wet weather. Limited spread from tree to tree takes place by water splash. Man is an important vector especially during pruning activities on young trees. He is also responsible for the introduction of the disease into new areas.
