Hole in ?ash?

[jamesfwpurdy]

His guys,

 

I hope someone can tell what these holes are in what i think is an ash stool.

 

They appear in the two stems on this stool and on another three a bit further up the hedge line.

 

Im a bit concerned as there is a very priductive stool next to it so wouldnt want anything spreading to that one.

Its Ash Canker. Not much you can do to stop the spread as it is bacterial.

Thankyou for the fast reply Matt.

 

Any ideas what would be the best option?

 

I was thinking to fell it and maybe scrub the stool to.try and stop it spreading.

This one i recon Pseudonona swoastonai

I think is more nectria canker, pseudomonas savastonai trends to have more blackened burrs than holes like this?

 

What do you reckon?

That looks more like it.

 

Just looks like firewood to me.

I thought the same . Any canker seems to burn just fine when its on ash

So is there no point in felling the affected trees to try & prevent spread to other healthy trees?

 

I have some very badly stunted trees some midly affected trees & some 100 percent healthy trees all close together, but it sees to have got alot worse in the last few years

 

One tree looks so badly diseased that I reckon it might die from it.

 

Also my coppiced willow have canker also
