armillaria mellea

[nuggsy]

can anyone tell me how the risk of this is reduced ?

its for a project at college but the question is asking for a cure but i have yet to find any information on cure ?

 

any help is much appreciated

It is commonly accepted that their is no cure for armillaria mellea nor control therapy...you can only take steps to reduce the an infection of armillaria within trees.

 

Where a tree is infected it is suggested that it is removed and that as much of the plant material i.e. main roots, fiborous roots and soil is also removed. Then subsequent replanting should focus on resistant species, exmaples include:

 

Acer negundo

Taxus spp

Juglans nigra

 

Alternatively restrict the movement of rhizomorphs through placing a barrier (plastic sheeting) in the ground around an infected tree, to prevent root contact with trees protected.

cheers m8y that was really helpfull

Although certainly not the best way to tackle the situation, you could use Armillatox.

I had an Oak with a massive encroachment issue of A. mellea a year or so back.

A liberal dowsing (manufacturers guidelines) of the trunk/route area, has completly halted the ingress of the rhizomorphs and there was no evidence of fruiting bodies last fall.

 

The major issue wiith this, is that you will possibly/probably lose any benefical micorhiza in the local vicinty.

 

Not so good .

 

Won't personaly gowing down this route again.

 

Does work however.

One should also bear in mind that control of armillaria is not an approved use of Armillatox, although it is still available as a high strength disinfectant. Unauthorised use of Armillatox would be frowned upon by the authorities that regulate pesticide use.

Keep your tree stock nice an healthy, the less pruning the better, make sure the trees get good drainage and mulch wherever possible

My father-in-law sought the advice of the RHS some years ago. They said that to (virtually) guarantee removal of the fungus from the immediate vicinity remove tree and all soil for 10m round and 2m deep! Otherwise be prepared for reoccurrence. Unfortunately he has many conifers (unfortunately because only a few are leylandii; there are many good specimens).

Hope this gives you an idea as to the degree of infiltration possible with armillaria.
