A Destructive Disease
Laurel Wilt
What is Laurel Wilt?
Laurel Wilt (LW) is a serious and deadly disease caused by the fungus Harringtonia lauricola. The disease was introduced by the invasive pest called the redbay ambrosia beetle (Xyleborus glabratus). This beetle was detected in Georgia (USA) in 2002 and by 2005 was detected in Florida. Laurel wilt has only been detected in trees of Lauraceae (Laurel Family) of which avocado is a member. Currently, five different species of ambrosia beetle have been documented capable of transmitting the pathogen to avocado trees.

Devastating Impact of Laurel Wilt
Hundreds of thousands of commercial avocado trees have died due to LW since 2012 when it was detected in the commercial avocado production area (Miami-Dade County). Many industry growers, educators and scientists have dedicated time and effort to test, experiment, and find solutions to combat LW and the ambrosia beetles that carry the pathogen.
