First report of Pseudomonas syringae pv. actinidiae in Georgia
In Georgia, unusual symptoms were observed in autumn 2013 on kiwifruit (Actinidia deliciosa cv. ‘Hayward’) plants growing in a 30-ha orchard located in the municipality of Lanchkhuti. The disease incidence was approximately 10%. Symptoms on leaves included brown angular spots surrounded by chlorotic margins that later became dark brown, and occasionally a reddish exudate was observed on the trunk. Laboratory tests (morphological, biochemical, pathogenicity, PCR) confirmed the presence of Pseudomonas syringae pv. actinidiae (EPPO A2 List) in diseased samples. This is the first time that the presence of P. syringae pv. actinidiae is associated with kiwifruit bacterial canker in Georgia.
The situation of Pseudomonas syringae pv. actinidiae in Georgia can be described as follows: Present, first found in 2013 in the municipality of Lanchkhuti (Western part).
