Due to a number of different reasons, some trees get infected by diseases. If left untreated, these diseases may spread to another tree, or another plant.
Tree diseases can weaken trees, cause them to die, and cause them to fall – potentially leading to accidents.
A professional arborist or tree surgeon can save trees and treat various tree diseases, as long as consulted the minute signs of tree problems are spotted.
Licensed arborists should be capable of diagnosing and possibly treating the following types of tree diseases:
Verticillium wilt – Verticillium wilt is a tree fungal disease that may be acquired from soil. Signs of Verticillium wilt include leaves suddenly starting to wilt and suffer discoloration. This disease can also cause branches to die prematurely. Low-nitrogen fertilizers can help treat Verticillium wilt. Trees that have this disease should be pruned regularly. Affected leaves and branches should be cut off immediately to prevent the disease from spreading.
Anthracnose – Another fungal disease in trees, Anthracnose are also known to affect various plants and shrubs. Anthracnose can cause unexpected curling of leaves and leaves falling without warning. This tree disease commonly affects trees and plants in cold, wet areas. Although Anthracnose isn’t known to kill off trees, they cause some trees to weaken, resulting in trees falling. Tree pruning and spraying of fungicide are typical steps taken to control Anthracnose.
Powdery mildew – Powdery mildew isn’t considered as a serious tree disease as this fungal infection mostly affects just the surface of trees or leaves. However, this disease might result in stunted growth of trees, its leaves, fruits, and flowers. To battle powdery mildew, you can spray fungicide on the trees and avoid their fertilization.
Beech bark disease – This tree disease causes mortality to beech trees. Beech bark disease is commonly spread by scale insects that feed on the sap of trees. Monitoring of trees affected by cutting off new roots and removing beech scale insects can help in saving trees with Beech bark disease.
