Ailanthus Wilt Research Study, Wayne National Forest, Ohio

The USDA Forest Service’s Wayne National Forest and the Northern Research Station is conducting a field trial of a native fungus (Verticillium nonalfalfae) as a means of killing the non-native invasive tree Ailanthus (Ailanthus altissima). This biological control method could be more cost effective than past treatment methods that rely on the use of chemical injections. This podcast was produced in partnership with the USDA Forest Service’s Wayne National Forest and the Northern Research Station to promote a greater awareness of the research study.
