National Research Highlights
Identification of a clover proliferation group phytoplasma as the probable cause of American elm Ttee mortality
Year: 2017
Forest Service scientists observed premature canopy decline symptoms in elm trees within their research plantations in midsummer 2016. They attributed canopy decline symptoms to a phytoplasma in the clover proliferation group previously not reported to impact forest trees. Mitigation approaches are currently being undertaken.
