Beyond Redbay: Monitoring Spread and Impact of Laurel Wilt in Sassafras Beyond the Gulf-Atlantic Coastal Plain
Mayfield A, Fraedrich S, Olatinwo R, Hwang J. 2020. Beyond Redbay: Monitoring Spread and Impact of Laurel Wilt in Sassafras Beyond the Gulf-Atlantic Coastal Plain. USDA Forest Service Southern Research Station
Conclusion: Laurel wilt is spreading in sassafras well beyond the Gulf-Atlantic Coastal Plain. Sassafras mortality in sites observed in the Piedmont/Sandhills and Mountains can progress rapidly. Beetle vector flight persists well into autumn and the pathogen likely moves underground in clonal sassafras clumps. Sites in this project will be monitored for a third year in 2020. Additional detections and impact of laurel wilt in the central and northern parts of the sassafras range appear likely.
