First report of Xanthomonas arboricola pv. pruni in Iran
In Iran, studies were carried out in stone fruit tree orchards in different parts of the province of Guilan (north of the country, along Caspian Sea) to detect the possible presence of Xanthomonas arboricola pv. pruni (EPPO A2 list). Cherry, plum and peach orchards were visually inspected and samples showing symptoms of bacterial leaf spot were collected from buds, leaves and shoots and then tested (bacterial isolation followed by biochemical and pathogenicity tests). The presence of X. arboricola pv. pruni was detected in samples of sweet and sour cherry (Prunus avium, P. cerasus) and plum (P. domestica). This is the first report of X. arboricola pv. pruni in Iran.
The situation of Xanthomonas arboricola pv. pruni in Iran can be described as follows: Present, first reported in 2005 in several Prunus orchards of Guilan province.
