Ash Die Back? Opinions please

[Tony Croft aka hamadryad]

Agree with regular ash canker in later stages, but not nectria.

How dose Fire blight enter into your train of thought Tony.

I know it mainly associated with rosaceae

 

not really familiar with the symptoms, seen a few shots now im starting to wade through some of these much smaller problems (smaller as in les obvious to the eyes, unlike a whopping great bracket!)

Are you talking about things like, Mosaic ,Verticillium wilt, Reversion virus, secondary stage mildew

rusts smuts and all those, Ted told me to get on em so I am, a lot of work to do!

The branch you seem concerned about looks like it is being subjected to a natural shedding process due to having been damaged, meanwhile a perennial canker is forming where the branch collar was, most likely N. ditissima/galligena, this could quite easily be linked with the previous damage.

 

The tree is not an advertisement of health, there appears to be quite a number of weakly attached branches (epicormic) and other parts with damaged bark etc.

 

Dosent look like chalara

 

No panic

"Doesnt look like" and "most likely" wont do for a potentially notifiable disease, or am I missing something?

 

Surely it is worth having a "professional" get a sample and have a proper look?

 

isnt THAT the current approach?

 

and isnt a perennial nectria or Ash canker defined as perennial and re infecting the edges of the tissues like target cankers,as opposed to Chalara and psuedomonas (Chestnuts) being the strip canker type? I.e a new column infected as apposed to the occluding tissues like in this example having strong occlusion

No

 

But we've only got a photograph to speculate on

So, our advice would be to send a sample in to FR would it not?

that's the only professional answer we can give

But you have already given your "professional" advise when you conclude the disease back in post 2! Its only on the last page so go back and have a look!

 

You said it was " Highly Likey" (I'm not going to patronise you as I'm sure you wanted to type "likely")

 

And, " The bark dying past the collar is a Giveaway"

 

How can you expect people to take you seriously with this very UNprofessional behaviour? HW

[sloth]

In post 6 he recommends sending a sample, and the difference between highly likely and likely results in the same ultimate diagnosis: maybe it is, and maybe it isn't. Picking on it does seem patronizing to me, sorry if you didn't intend it to come accross as such.

Bark dieing beyond the collar can be a symptom.

It was never a professional opinion, just an informal one (from someone who knows their onions and has a passion for them) on a public forum.

 

None of us are perfect: can't we all just get along!!?!?!?
