Mould on Beech tree

[Gareth Smith]

Discovered this today at a clients property on a semi mature beech on the edge of a woodland. No other beech in close proximity affected. Any idea please ...

Looks very like Beech bark disease to me, you can scrub it off using a hard wet brush

beech coccus - washing up liquid will sort it - brush it on - cant see bb disease from the pic but it can arise from the beech coccus infestation

What this process will do is suffocate the scale insects

Beech Bark Disease is a fungus Nectria coccinea, hte tree gets nfected by it due to the spores being carried on boring insects Cryptocuccus fagisuga. That looks liek a heavy putbreak, get them scrubbed off before spring and it might not bee too late for the tree. A couple of heavy outbreaks in a row can be enough to kill a tree off slowly a few years after te insects are gone.
