Keeping an Eye on Laurel Wilt Disease

March 25, 2011

Laurel wilt is a deadly disease of redbay (Persea borbonia) and other tree species in the Laurel family (Lauraceae). The disease is caused by a fungus (Raffaelea lauricola) that is introduced into host trees by a non-native insect, the redbay ambrosia beetle (Xyleborus glabratus). Laurel wilt can have a devastating impact on Florida’s avocado industry, as avocado is a tree in the Laurel family.

DPI implemented the Save the Guac campaign to help Floridians get involved with protecting the state from laurel wilt disease and the redbay ambrosia beetle. Laurel wilt has been spreading throughout the state since its introduction in 2005, and has also been detected in Georgia and South Carolina. If you suspect laurel wilt disease in your yard, or think you have found a redbay ambrosia beetle, please submit a sample to DPI using the forms below.
