Anthracnose is one of the most common diseases on plants such as oak, maple, and sycamore. Anthracnose usually causes little damage to the tree but severe outbreaks do occur causing death of the tree. Symptoms vary with the plant host. Maple symptoms include brown lesions that spread along the larger veins, circular brown to reddish brown spots with tan centers, and irregular blotches that kill large sections of a leaf. Oak Symptoms on the young leaves and shoots include browning and shriveling of the blighted tissues. Control for anthracnose includes raking up the leaves before budbreak and discard, fertilize and irrigate trees that have foliar blighting and defoliation, fungicide applications work as well.
