New Research on Oak Wilt Leaf Testing

Oak wilt can now be diagnosed using leaf petiole samples, saving time and money. Click here for more information.

Michigan Invasive Species Grant Program awards Dr. Monique Sakalidis for her work on Epidemiology, biology and population genetics of Oak Wilt

MSU Department of Plant, Soil, and Microbial Sciences, and Department of Forestry’s Dr. Monique Sakalidis and her collaborators, including Dr. Deb McCullough, Dr. Bert Cregg and Dr. Jan Byrne, focused on refining Michigan-specific oak wilt control measures. They studied the epidemiology, biology and population genetics of oak wilt. They monitored fungal spore production and host tree susceptibility, and evaluated molecular methods to identify infected trees and the source of spread. They also determined high-risk periods when insects are most likely to introduce the oak wilt fungus into trees.

Stay tuned for future publications on this work.
