laurel wilt
Laurel wilt, also called laurel wilt disease, is a vascular disease caused by the fungus ''Raffaelea lauricola'',〔Harrington, TC; Fraedrich, SW; and Aghayeva, DN. 2008, ''Raffaelea lauricola'', a new ambrosia beetle symbiont and pathogen on the ''Lauraceae''. Mycotaxon. 104: 399 - 404.〕 which is transmitted by the invasive redbay ambrosia beetle, ''Xyleborus glabratus''. The disease affects and kills members of the laurel family. The avocado is perhaps the most commercially valuable plant affected by laurel wilt.
== Symptoms ==
Symptoms of laurel wilt include wilted stems and leaves and dark streaking in the wood.〔(Redbay Ambrosia Beetle-Laurel Wilt Pathogen: A Potential Major Problem for the Florida Avocado Industry )〕 Laurel wilt can spread in at least two ways: one is via the beetle's natural reproduction and migration. A second way is through the sale and transport of beetle-infested wood, a result of redbay's use as firewood and for outdoor grilling.〔〔
