August Avocado Grower Seminar Topic: Laurel Wilt Disease

Jul 6, 2017

 

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 nonnative insect, the redbay ambrosia beetle (Xyleborus glabratus). https://youtu.be/2x7vgFWLHkY
