How do I get rid of Armillaria?
Cut out and burn diseased bark and roots, and paint cuts with a plastic paint. Leave the crown and roots permanently uncovered and do not replace soil during cultivation. This will halt the development of the disease, as exposure to air kills Armillaria. Remove and burn all badly affected trees, including roots.
Is Armillaria invasive?
The fungal pathogens that cause Armillaria root disease (Armillaria species) on diverse tree hosts around the world can act as invasive pathogens when they are introduced to new areas.
What is the cause of Armillaria root rot?
Armillaria root rot is a disease of trees and woody plants, although it also affects palms, succulents, ferns and other herbaceous plants. This disease is caused by fungi in the genus Armillaria, also known as “oak root fungus,” although the fungus has no specificity for oaks.
What trees are affected by Armillaria root rot?
Armillaria root rot infects many crops and native and ornamental plants. Common hosts include avocado, cherimoya, citrus, and oaks. The fungus persists in infested roots, stumps, and wood in soil, infecting new plantings and spreading to infect nearby plants.
How is Armillaria spread?
Armillaria can survive many years in wood debris like an old stump or root system. New infections occur when healthy roots grow close to diseased roots. Black shoestring-like strands of fungal growth, called rhizomorphs, can spread up to 10 feet from an infected tree or stump to infect healthy roots.
How do you treat tree root rot?
Begin by carefully digging around the younger tree, making sure to remove as much of the intact root system as possible. Rinse off the root ball with your garden hose, and carefully cut away the affected sections. Treating the tree roots with fungicide can help prevent root rot from forming in the future.
How do you treat oak root fungus?
There are no effective fungicide treatments for the control of the disease in living trees. The fungus can survive for many years in the dead or living tree roots. Remove as many roots from infected soil as possible before replanting. Armillaria is sensitive to drying and grows most rapidly under wet conditions.
How do you treat root rot?

How far can honey fungus spread?
It is this ability to spread long distances through soil that makes honey fungus such a destructive pathogen, often attacking plants up to 30m (100ft) away from the source of infection.
How do you treat root rot naturally?
TWO Simple Ways to Cure Root Rot:
- Hydrogen Peroxide (3%) Mix 2 parts water, 1 part hydrogen peroxide, soak your soil with this mixture.

How do you get rid of tree root fungus?
Is there a fungicide for root rot?
For many years the best and most reliable fungicides for black root rot have included the active ingredient thiophanate-methyl (or others in the benzimidazole group – MOA 3). While other fungicides have sometimes given some control, those containing a benzimidazole have always provided the best control.
