General Comments

A bacterial disease whose main hosts include grapevine, citrus, coffee and almond. Detected in Germany in 2016 in Nerium oleander. Some uncertainty about the potential to establish under UK climatic conditions, which will be investigated further. As an EU regulated pest, should an outbreak occur, there would be a need for eradication action, which would result in environmental and social impacts.
