There are a variety of bacterial and fungal infections that can cause damage to your trees. Arborists can help diagnose and treat tree problems. To explore what may be wrong with your trees, get to know these common tree diseases.
Fire Blight
Fire Blight is a bacterial infection that is most prevalent in apple and pear trees. Warm, humid weather is an ideal environment for this bacterium to spread rapidly. As your tree or shrub blooms, you may notice brown to black streaks on the leaves and flowers. If left untreated, Fire Blight will gradually infect the entire tree, eventually killing it.
Fungus
Fungi is naturally occurring throughout nature and usually does not affect tree health. However, some types of fungal infections can cause problems such as weakening of stems and branches. Cottonwood and Mulberry are prone to wood rot caused by fungal infection.
Powdery Mildew
Powdery Mildew is a fungal infection that affects the leaves and stems of indoor and outdoor plants and shrubs. Unlike other fungal infections, it does not require moisture to grow. Infections are spread through spores carried by the wind. Powdery mildew can be identified through grayish white, powdery patches on leaves and stems. Without treatment, the leaves will turn yellow and wither. Eventually, the disease can kill entire branches.
Rust Disease
Rust disease is a common fungal infection that can weaken the trunks and branches of trees. Infections can be seen in the form of small reddish or yellow bubbles on the lower surface of leaves, resembling the appearance of rust. These symptoms usually appear late in the summer season and may cause early leaf loss.
