Anthracnose

Anthracnose is a common problem on trees in Southeast Nebraska during cool, wet spring weather.

Symptoms first appear as water-soaked spots on the expanding leaves. The spots enlarge and develop brown lesions. The lesions are often associated with leaf veins and margins. Growth of the infected tissue slows or stops as the rest of the leaf continues to expand. As a result, the leaf tissue around the lesion becomes twisted and wrinkled. Defoliation also may occur.
