How to detect the armillaria root disease?
Answer / suvidha
Early symptoms of the disease can often be difficult to
detect but may include dieback of the limbs and branches,
yellowing of foliage, splits in the trunk of the infected
tree, poor vigour, exudates from the trunk (kino
production), scars may form on the trunk and darkening of
the larger roots.
Removal of the bark may reveal the presence of mycelial
fans ? these are large sheets of fungal growth, usually
white in colour, which will have a characteristic mushroom
odour. The surface of the affected timber is often pitted
in appearance.
The fungus produces mushrooms in May?June. These are olive
brown to yellow in colour, can be up to 12 cm in diameter
with a stipe (stalk) of up to 15 cm high, although usually
less. The stipe will have an annulus (the ring of tissue
around the stipe) that should be quite obvious. The spores
of the fungus are white and these often coat the surface of
the mushrooms.
