First report of Pseudomonas syringae pv. actinidiae in Portugal
In March 2010, symptoms of bacterial canker were observed on two-year-old plants of Actinidia deliciosa cv. ‘Summer’ in kiwifruit orchards in the province of Entre-Douro-e-Mińo, North of Portugal. The symptoms were characterised by dark brown spots surrounded by yellow haloes on leaves, and cankers with copious reddish exudate on twigs and stems. In some cases, the disease incidence reached up to 30%. Laboratory analysis confirmed the presence of Pseudomonas syringae pv. actinidiae (EPPO Alert List) in diseased kiwi plants. This is the first report of this bacterium on A. deliciosa in Portugal.
The situation of Pseudomonas syringae pv. actinidiae in Portugal can be described as follows: Present, first found in 2010 in kiwifruit orchards in Entre-Douro-e-Mińo province.
