Control and Management
Research is being conducted to develop, evaluate, and improve regulatory and management tools to protect and conserve ash trees from EAB in our urban and natural forests. For urban forests, researchers found that periodic injections of systemic insecticides can successfully protect ash trees from decline and mortality as EAB invades a community. In natural forests, biological control is being used to suppress high EAB populations, thereby helping to conserve some surviving and regenerating ash for future generations. Researchers are also evaluating these surviving or “lingering” ash for EAB resistance, studying resistance mechanisms, and ultimately developing ash trees resistant to EAB through hybridization of North American and Asian ash species. To control and reduce the spread of EAB by humans, researchers developed regulatory treatments of ash firewood and high-value logs such as debarking or heat treatment.
