First report of Pseudomonas syringae pv. actinidiae in Spain
In spring 2011, bacterial canker of kiwifruit caused by Pseudomonas syringae pv. actinidiae (EPPO Alert List) was detected for the first time in Spain. Symptoms were observed on two-year-old plants of Actinidia deliciosa cv. ‘Hayward’ and of A. chinensis cv. ‘Jin Tao’, in two orchards (15 and 23 ha) located in Burgueira (province of Pontevedra, Galicia). Galicia is one the major kiwifruit-growing area of Spain. Bacterial colonies were isolated from infected leaves and laboratory analysis (biochemical, molecular, and pathogenicity tests) confirmed the presence of P. syringae pv. actinidiae. The NPPO of Spain noted that the plants had been imported from an Italian nursery. All infected plant material has been destroyed and surveys are being undertaken.
The situation of Pseudomonas syringae pv. actinidiae in Spain can be described as follows: Transient, first found in 2011 in 2 orchards in Galicia, under eradication.
