Detection and characterization of Pseudomonas syringae pv. actinidifoliorum in kiwifruit in Spain

摘要

Aims: Bacterial canker of kiwifruit caused by Pseudomonas syringae pv. actinidiae (Psa) is currently the major threat to its commercial production worldwide. In 2011, the most virulent type (Psa3) was detected for the first time in Northwest-Spain, in the province of Pontevedra. In 2013 surveys, leaves and flower buds with mild symptoms were observed in Actinidia deliciosa `Hayward' vines in an orchard at the province of A Coruna, suggesting the presence of P. syringae pv. actinidifoliorum (Psaf).
