A new disease was observed during the spring and autumn of 2009 and 2010 on kiwifruit plants (Actinidia deliciosa cv. Hayward) in Rize Province of Turkey. Disease incidence was estimated as 3% in approximately 10 ha. Symptoms were characterized by dark brown spots surrounded by yellow halos on leaves and cankers with reddish exudate production on twigs and stems. Eight representative bacterial strains were isolated from leaf spots and tissues under the bark on King's B medium (KB) and identified as Pseudomonas syringae pv. actinidiae on the basis of biochemical, physiological (1,2), and PCR tests (3).
