Recent research includes a retrospective assessment of imidacloprid treatments used as part of an integrated pest management plan to reduce the impact of the hemlock woolly adelgid on eastern hemlock in the Great Smoky Mountains National Park. The project focused on the following:
persistence and efficacy of imidacloprid and its metabolites in eastern hemlock
assessment of insecticide concentration in different size eastern hemlock trees, resulting in a model to optimize insecticide dosage
presence and concentration of imidacloprid in streams
potential non-target insecticide impacts to aquatic macroinvertebrate communities
Increased knowledge of insecticide persistence in various size eastern hemlock trees and potential non-target impacts to surface water quality have improved management decisions. This will enhance eastern hemlock health in the southern Appalachians.
