Shade Tree Anthracnose (PPFS-OR-W-23)

Anthracnose is the common name given to several fungal shade tree diseases with similar dark, irregularly-shaped leaf lesions. While they are primarily foliar diseases, damage on some hosts may extend to twigs, branches, and buds.  Resulting defoliation and dieback, especially if it occurs year after year, can weaken trees and make them more susceptible to environmental stresses and secondary pathogens

This publication discusses anthracnose on the shade tree hosts most commonly affected in Kentucky: ash, maple, oak, and sycamore.

Shade Tree Anthracnose (PPFS-OR-W-23) is available online.
