What's going on with this ash?

[Daniël Bos]

As per title really, it's in a hedgerow with dozens of others that all look normal. Some in various stages of dying etc, but this is the only one that looks like this?

It looks to have no smaller twigs at all, but was in leaf this year?

There's also some vertical cracks in the bark, not sure if they're related?

Just looking for some insights on how and why really.

 

Thanks.

Possibly salt damage in the crown and either a very wide expansion crack or the onset of Pseudomanus syrigae <spelling.

first thoughts are ash canker! salt damage is possible, is it near the coast?

[Daniël Bos]

Thanks guys, it's in central Bedfordshire so about as far from the coast as you can get.

This is the only one like this amongst 100 or so.

No signs of fruiting bodies anywhere. It was exactly like this last winter.

looks like Ash bacterial canker which is caused by the bacterium Pseudomonas savastanoi. but i could be wrong.

[Daniël Bos]

Any clues on the prospects if it is ash canker, and symptoms to look for to confirm diagnosis?

 

Much appreciated guys.

Google Pseudomonas syringae ssp. savastanoi pv fraxini

 

Plenty on the internet:biggrin:

 

Doesn't really do that much harm to the tree unless it's a forestry tree (spreads easily and can disfigure the wood). Over time it will not be great for the tree, but that is over time

And succeed!

 

Any idea how the bacterium is related to the lack of smaller twigs?

 

Preferentially invades smaller twigs?

 

Larger twigs resist girdling better?
