What is Daldinia concentrica effects!

[Silver Back]

Well IMHO, I believe it is already present in the wood, and will only begin to grow when conditions are right. So ash, main host, with this on is probably more then likely already stressed for some reason and the fungus then takes advantage.

As was inferred in the above post...Im not sure why you should try to "eradicate" the infection if it means the tree needs to be pruned and by that I think I mean, heavily pruned. Trying to read between the lines, if one views the tree as needing work, this would surely be for reasons of public or material safety?

The physiological preference is to allow as much of the tree to remain intact as is possible probably. Remember it costs the tree in energy to access stored energy further stressing the plant thus weakening its natural, systemic defences. This is the result of pruning out diseased wood. Not always the best or most expedient & timely of operations. From the trees point of view.

It is this that may be considered when making decisions as to how best to proceed with regards the management of a situation in which trees are often the understated participants. That the tree is protected by an order, should at least indicate that it is or has been in the past, valued for its amenity contribution. Good luck with it anyway.

The story is a large ash growing on a boundary within a TPO blanket order after development. The customer would love it down due to its size and proximity to the house. Personally i am not looking to find ways to fell just best practice.

I assume thats for H&S reasons and not just because it blocks out light and drops leaves everywhere.

 

I would say that if it is a H&S issue then probably the least would be to remove the affected limbs and only if required do any other works to balance it out.

 

Oh and do get them to monitor it for inonotus hispidus etc if it stays up.

A tree would have to be in severe stress before this became heavily parasitic, it is VERY weakly so. I rarely concern myself with it on limbs as it is usualy 99% on dead wood.

 

AA teccie is right in it being very common in tandem with Hispidus, the Hispidus causing death and necrosis in the cambium exposing heartwood enabling invasion/colonisation by D. concentrica.

 

There are seven species of Daldinia, they prefer Ash, but will also be found on Chestnut( horse) beech and Acers occasionaly.
