First report of laurel wilt caused by Raffaelea lauricola on bay laurel (Laurus nobilis) in the United States.
In September 2013, a 6-m-tall bay laurel (Laurus nobilis) in Gainesville, Florida, USA, exbibited wilted leaves, discolored sapwood and ambrosia beetle (Xyleborus glabratus) entrance holes. In addition, the tree was growing close to an avocado that succumbed to the disease months earlier. Diseased samples were collected and analysed in the laboratory. The saucal pathogen was identified as Raffaelea lauricola based on cultural, morphological, genetic (PCR) and pathogenicity analyses. This is thought to be the first report of Laurel wilt caused by R. lauricola on bay laurel in the USA.
