Mulberry Tree Diseases

Mulberry trees (Morus spp.) are susceptible to a variety of diseases, both fungal and bacterial. These diseases can cause leaf spots, dieback, wilting, and even death of the tree.

Bacterial blight

Bacterial blight is a common disease of mulberry trees caused by the bacterium Pseudomonas syringae. The disease is characterized by small, brown spots on the leaves. These spots eventually enlarge and coalesce, causing the leaves to wilt and drop. Bacterial blight can also cause cankers on the branches and trunk of the tree.

Canker

Canker is a fungal disease of mulberry trees caused by the fungus Botryosphaeria dothidea. The disease is characterized by sunken, discolored areas on the bark of the tree. These areas eventually enlarge and girdle the tree, causing it to die.

Dieback

Dieback is a condition in which the branches and twigs of a tree die back. Dieback can be caused by a variety of factors, including drought, pests, and diseases. In mulberry trees, dieback is often caused by the fungus Botryosphaeria dothidea.

Leaf spot

Leaf spot is a fungal disease of mulberry trees caused by a variety of fungi. The disease is characterized by small, brown spots on the leaves. These spots eventually enlarge and coalesce, causing the leaves to wilt and drop.

Rust

Rust is a fungal disease of mulberry trees caused by the fungus Melampsora medusae. The disease is characterized by orange or yellow pustules on the leaves. These pustules eventually release spores that spread the disease to other plants.

Verticillium wilt

Verticillium wilt is a fungal disease of mulberry trees caused by the fungus Verticillium albo-atrum. The disease is characterized by wilting and yellowing of the leaves. The leaves eventually die and the tree may eventually die.

White mulberry mosaic virus

White mulberry mosaic virus is a viral disease of mulberry trees caused by the virus Bymovir muri. The disease is characterized by yellow or white streaks on the leaves. The leaves eventually become distorted and the tree may eventually die.

Management of Mulberry Tree Diseases

The best way to manage mulberry tree diseases is to prevent them from occurring in the first place. This can be done by:

• Planting resistant varieties of mulberry trees.
• Avoiding overhead irrigation, which can spread fungal spores.
