GAINESVILLE, Fla. — With the laurel wilt pathogen threatening the Florida avocado industry, a UF/IFAS tropical fruit scientist will lend his expertise at the World Avocado Congress in September in Lima, Peru.
Jonathan Crane, professor in horticultural sciences, will give an opening presentation titled: “The Potential for Laurel Wilt to Threaten Avocado Production is Real” at the meeting, Sept. 13-18. With this talk, Crane will provide evidence that laurel wilt will spread throughout North America and will pose a threat to native trees and to commercial avocado production.
Later, Crane will present a paper titled: “Current status and control recommendations for laurel wilt and the ambrosia beetle vectors in commercial avocado orchards in South Florida.” Crane co-authored the paper with Daniel Carrillo, assistant professor in entomology; Randy Ploetz, professor in plant pathology; Edward Evans, associate professor in food and resource economics and Aaron Palmateer, associate professor in plant pathology – all of whom work at the UF/IFAS Tropical Research and Education Center in Homestead. The final co-author is Don Pybas, director of the Florida Avocado Administrative Committee.
Several ambrosia beetle species transmit the laurel wilt pathogen to avocado trees, killing most of them, threatening an industry with a $100 million-a-year economic impact on Florida. The original ambrosia beetle vector of laurel wilt was discovered in the U.S. in Georgia in 2002 and since that time has spread to seven additional states. Laurel wilt has begun to slightly affect commercial avocado production in Florida.
