Recommendations for the Detection and Mitigation of Laurel Wilt Disease in Avocado and Related Tree Species in the Home Landscape

This devastating disease has spread rapidly along the southeastern seaboard of the U.S. since 2003 and has begun to affect commercial avocado production in Florida. Laurel wilt is spread by ambrosia beetles and interconnected roots of avocado trees. The time from infection to tree mortality ranges from four to eight weeks. To prevent spread of the disease, it is important that trees be destroyed as soon as they are affected by the disease.

"Florida's agricultural industry generates more than $103 billion in annual economic impact and employs more than 500,000 people. Florida's farmers produce nearly 300 commodities, and winter vegetables and citrus consistently lead the national rankings. To meet the needs of this diverse industry, research and extension programs in the areas of fruit and vegetable production, postharvest technology and weed science are delivered on a county, regional and statewide basis using a variety of methods including field days, intensive hands-on training, and distance learning. Excellence in programming facilitates the exchange of information and technology and contributes to the professional development of extension faculty and the agricultural clientele they serve."
