Fruit Tree Root Disease

Fruit trees are susceptible to a number of bacterial and fungal root diseases. These include Phytophthora root disease, armillaria root rot, white root rot, black root rot and clitocyle root rot.

Fungal Diseases

Fruit tree roots are prone to fungal diseases. These affect the growth and vigor of the trees. One of the symptoms of fungal disease is small mushrooms growing from the tree base.

Bacterial Root Rot

Fruit tree roots can suffer from bacterial diseases that create spongy galls on the roots and crowns of trees. These galls grow harder over time and particularly stunt the growth of young trees.

Common Root Disease

Cherry, peach and apple trees are often struck by Phytophthora root disease. This is one of the most common and fatal root diseases of fruit trees. Southern Blight infects the roots and lower stems of trees, leading to the trees' decline and death.

Significance

No chemicals can prevent or control the majority of fruit tree root diseases. Though fungicidal sprays can be used as a prevention against Phytophthora root rot, little can be done after infection sets in.

Prevention

The best way to avoid root disease is to take precautionary measures to discourage diseases and pests. Do not over water the trees. Regularly clean and burn fallen leaves, remove fruits before they rot, and spray trees with dormant oil during fall.
