Various factors, including insects, bacteria, fungi, and environmental stress, can cause tree diseases.
While some tree diseases are treatable, others can lead to the tree’s death. It’s essential to identify the signs and symptoms of common tree diseases so that you can take steps to prevent or treat them.
Common Tree Diseases
Several common tree diseases can affect both deciduous and evergreen trees. Some of the most common include:
- Anthracnose: A fungal disease that affects trees during cold, wet weather conditions. Symptoms include leaf spots, premature leaf drop, and twig dieback. This disease is most common in maples, oaks, and sycamores.
- Bacterial Blight: Bacterial blight is caused by a bacteria called Pseudomonas syringae and affects a tree’s leaves, twigs, and fruits. Symptoms include small brown or black lesions on the leaves and fruits and twig dieback. Bacterial blight is most common in cherries, plums, and pears.
- Canker: Canker is a tree disease caused by various fungi and bacteria. It leads to dead areas, or cankers, on the tree’s bark. Canker is most common in maples, oaks, and willows.
- Damping-off: Damping-off is a fungal disease that affects young trees and is caused by fungi in the soil, leading to the tree’s roots rotting. Symptoms include wilting, yellowing leaves, and stunted growth. Damping-off is most common in pines and firs.
- Dutch Elm Disease: Dutch elm disease is a fungal disease that affects elm trees. It is spread by a beetle that bores into the tree’s bark. Symptoms include yellowing and wilting leaves, as well as twig dieback. Dutch elm disease can kill a tree within one year of infection.
- Fusiform Rust: Fusiform rust is a fungal disease that affects pines and is spread by wind-blown spores. Its symptoms include yellowing and falling needles and cankers on the tree’s trunk. Fusiform rust is most common in loblolly pines and slashes pines.
- Powdery Mildew: This fungal disease affects trees during warm, humid weather conditions. It is most common in maples, oaks, and sycamores. Symptoms include white or gray powdery growth on the leaves and stunted leaf growth.
- Root Rot: Caused by various fungi and bacteria, root rot shows symptoms such as wilting, yellowing leaves, and stunted growth. Root rot is most common in pines and firs.
Treatment of Tree Diseases
The treatment of tree diseases depends on the type of disease. Some conditions, such as Dutch elm disease, can be fatal to trees and cannot be cured. However, there are treatments available for other common tree diseases, including:
