Tree Disease

Tree diseases are ailments or infections that affect the health, growth, and overall well-being of trees. They can be caused by various factors, including fungi, bacteria, viruses, environmental stressors, pests, or a combination of these. Tree diseases can impact trees of all ages and species and can lead to symptoms such as discoloration, wilting, leaf loss, cankers, or decay. Here are some common tree diseases:

1. Dutch Elm Disease: This fungal disease affects elm trees and is spread by elm bark beetles. It causes wilting, yellowing, and browning of leaves, eventually leading to tree death.

2. Oak Wilt: Oak wilt is caused by a fungus and primarily affects oak trees. It disrupts the tree's water-conducting system, leading to wilting, leaf discoloration, and death.

3. Chestnut Blight: This fungal disease affects chestnut trees, causing cankers on the trunk and branches. It is responsible for the decline and near extinction of the American chestnut tree.

4. Apple Scab: Apple scab is a fungal disease that affects apple trees. It causes dark, scaly lesions on leaves, fruit, and twigs, leading to reduced fruit quality and yield.
