beech tree bleeding canker?

[treeseer]

... or Nectria ditissima combined with Armillaria mellea, as I suggested before.

How does one find out--remove dead bark, inspect for mycelia..

 

If A.m., which treatments to specify?? Remove all dead and decayed tissue, rinse, dry, cauterize lesions, replace soil, invigorate roots?

Could be, could also be just fluids coming up from the roots via the xylem turning orange when exposed to oxygen, like - as before mentioned - can be seen in damaged or cut Betula, Prunus and Acer.

 

Thanks for making me look again at the exudate's of these situations, so the liquid is in fact the trees own sap bleeding through the lesions made by armillaria attack. here the oxidation of Liquid amber sap causing it to go white:001_cool:

Guy,

I've answered both questions you over and over again ask several times, so search through my posts and find the answers yourself.

right then; all of the above!

As always incorrect and extremely biased by your narrow minded vision on trees. You never learn, do you ?

Still waiting for your vision to get beyond the mycological aspect, and hypothesizing fungal attack in lieu of evidence.

I will not speak for anyone else treeseer, but to be perfectly frank you could do with respecting the skills and experience some of us have with regards to P&D.

 

You should know as well as anyone that experience in the field is 99% of the equations, that "evidence" leads to the conclusions of experienced folk, and that PROOF is only a matter of formality, that final 1%, in most scenarios, at least when you are well tuned in to your subject.

 

The fact remains that fungi are the most prevalent of factors affecting the tree, and if you dont realise that STILL then I guess I at least will let you be and give a wide berth as i for one have never been fond of listening to scratched records.

 

order= Tree- fungi-environment- other factors. simples

I could either provide a short or a long list of references to scientific articles and books on in situ and in vitro research on "fungal attack" and fungal wood degrading strategies all with valid evidence on the subject, but I'm afraid you would not be able to see "the wood for the trees" and as you've already gone to sleep after reading my short reply to your over and over again repeated same questions, I have answered several times, I will refrain from that.

 

Instead, for those who are awake, I have a simple question : can you explain why Meripilus giganteus is extremely rare to even non-existing for several decades in undisturbed beech woodlands on the European continent and at the same time is present to such a still increasing extreme in managed beech woodlands and on urban and rural beeches ?

And why and how has M. giganteus succeeded in attacking so many other tree species as beech, that are not invaded by M. giganteus under original forest or woodland tree species specific ecosystem conditions ?

[RobArb]

Because of all the likkle "good" funguys:biggrin: doing their respective jobs in the woodland ecosystem?
