Anthracnose

[View Larger Image]

Anthracnose is the name given to a group of fungal diseases that cause leaf spots, blotches along leaf veins and distortion of the leaves. Infected leaves eventually drop off the tree. Some of these fungi are capable of infecting twigs, causing lesions and twig dieback. This disease is seen most frequently on ash, oak, and maple trees. Weather conditions play a large role in the severity of the disease. In years when the spring is cool and wet the disease can reach epidemic proportions.
