Beech Leaf Disease

BEECH LEAF DISEASE: NEMATODES ATTACKING BEECH TREES!

Wednesday, October 22, 2025, 6:00 PM - 7:00 PM

The new Beech Leaf Disease has been in southeastern New York since 2019—and it has been spreading. Learn about the new invasive exotic nematode that causes the foliar infections, and how the disease progresses until even large trees may be killed in 6-10 years. There are no guaranteed measures for stopping the advance of Beech Leaf Disease in the wild on the native American beech, but research has shown some benefit to treatments on landscape ornamentals (usually European beech). This talk will cover the history of the disease, the symptoms, the geographic range, , and our local NY observations. Injection treatments and sprays for management of the disease will be discussed.
