Abstract
A description is provided for Pseudomonas amygdali. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: On Prunus amygdalus[Prunus dulcis]. Other stone fruits have been inoculated without success. DISEASE: Bacteriosis of almond. Perennial cankers are formed on branches and twigs, usually at leaf scars. They begin as swellings of the bark that crack open and become surrounded by swollen and darkened cortical tissue. They remain actively growing all the year round, reaching 3-5 cm long in 2 years and eventually up to 15-20 cm. If a branch is girdled by canker the part above dies. Buds near the cankers often fail to open in the spring and as the disease progresses trees steadily decline. GEOGRAPHICAL DISTRIBUTION: Greece (Crete), Turkey (55, 324). TRANSMISSION: This has not yet been reported, but as cankers are usually sited at leaf scars it seems likely that bacteria are carried to these scars in wet conditions at, or soon after, leaf fall.
