Anthracnose is a fungal disease that typically occurs in the spring when the weather is cool and wet, it thrives during moist and warm conditions. It tends to dissipate once dry and hot weather begins but is usually spread through watering. It most commonly affects elm, oak and sycamore trees but can also affect ash, maple, and willow trees. Besides trees it can infect shrubs, vegetables, flowers, and fruit.


This disease causes dark lesions on leaves, the leaves can also become curled and distorted. In severe cases, lesions and cankers can occur on stems, girdling and dieback may also occur. Typically, this fungus leads to defoliation of trees from the ground up.
