This NebGuide describes anthracnose diseases in sycamore, ash, oak, maple and walnut trees and offers suggestions for control.
Anthracnose diseases affect a wide variety of plants including many popular shade trees. Sycamore, ash, oak, maple, and walnut commonly exhibit symptoms each spring. Although the symptoms may appear serious, anthracnose diseases rarely kill trees. In most cases, healthy trees quickly recover from anthracnose infections with little damage to their long-term health.
