Occurrence of Xanthomonas arboricola pv. pruni in Lazio (IT)
During spring and summer 1993, symptoms of necrotic spots on leaves, water-soaked lesions on fruit, and cankers on branches were observed on plum trees (Prunus domestica cvs President and Angeleno) in several orchards situated in the north of Lazio (central Italy). Investigations revealed the presence of Xanthomonas arboricola pv. pruni (EPPO A2 quarantine pest). The authors noted that this is the first report of this pathogen in Lazio.
