WHO CAUSES IT?
Armillaria mellea is a phytopathogenic fungus that causes the disease known as armillaria, root rot or white root rot in apple trees and other fruit trees. The fungus spreads through rhizomorphs, root-like structures that spread through the soil and can infect new plants by coming into contact with their roots. Armillaria mellea can survive on dead wood and plant debris, persisting in the soil for long periods.
SYMPTOMS
Armillaria, root rot or root white disease in apple trees produces a decomposition of the roots, which leads to the loss of vigor of the plant and its eventual death. Symptoms may be subtle at first, but may become more obvious as the disease progresses.
• Loss of vigor in the plant.
• Wilting and yellowing of the leaves.
• Appearance of mushrooms at the base of the trunk or near the roots.
• Root decomposition.
