First record of Xanthomonas arboricola pv. corylina in Sardegna and Sicilia (IT)
In Italy, during surveys done in hazelnut (Corylus avellana) orchards in Sardegna (near Nuoro), and Sicilia (near Messina and Catania), symptoms resembling those of Xanthomonas arboricola pv. corylina (EPPO A2 list) were observed. Water-soaked necrotic spots were observed on fruit husks and twigs sometimes showed partial die-back. Laboratory and pathogenicity tests confirmed that Xanthomonas arboricola pv. corylina was the causal agent of the disease observed. This is the first record of X. arboricola pv. corylina on both islands. In Italy, X. arboricola pv. corylina had been reported previously in Lazio (EPPO RS 519/12, 1992).
The situation of Xanthomonas arboricola pv. corylina in Italy can be described as follows: Present, occurs in Lazio and reported in 2006 in Sardegna and Sicilia.
