Bad News Ash Disease discovered in East Anglia

Thanks for the link. It raises the question how long are the spores viable? There seems some scope for intervening with leaf litter at the sexual stage.

 

Why does the anamorph have a different name from the telemorph?

News just now: 10 sites confirmed in E.Anglia, 7 more suspected, 5 suspected in Kent.

 

I suspect it will go the way of other notifiable diseases - progression from notifiable to giving up.

 

One of my earliest memories is the end of the elms, which is what got me in to trees in the first place. I was about the age my eldest daughter is now. I wonder what landscape she will have in 35yrs time.

Does it effect all species of Ash trees?

I saw some young Ash trees looking like photo 1 back in the early summer at a local hospital, at the time thought it was drought. Will have to have another look.

Thanks Tony Good film. By the way it attacks the tree by spreading up and down from the infected leaf can the a tree be lopped or pollarded to keep it or has it got to be fell if court so enough.

only time will tell, I have no personal experience of this as yet, though I took an ash down last year that had died suddenly, from what I thought was armillaria but something was not right about it. I have the shots somewhere still I hope just a question of finding them amoung the tens of thousands!

Interesting you tube video Tony.

Stated that no sexual stage found in UK.

So all these trees were imported or infected from windblown spores.

If this is the case then next year I guess will likely see a massive increase in cases found.

Thanks for the helpful link Tony.

 

Woody Paul's question on amputation as a control measure is a very good point. Maybe folks working on the problem in continental Europe will have something to say on that. Where is Gerrit when you need him?

Reading some documents from guys at FR that a certain % of parent trees will show resistance to Chalara.

 

FC operations appear to be putting costings together for sanitation of sites where outbreaks have occured although my gut feeling is that its probably not viable and could just be a waste of money, especially if you end up actually removing trees in an area which may be resistance and therefore be key to re-population ash

 

Here is some more info including scientific papers for those of you that have access to these, although some have the full paper available directly from the site

Im going to ask the mods to sticky this thread

It seems almost unbelievable that national notification and action has just got started when 99% of Ash trees have dumped their leaves for the winter

My thoughts precisely. See my thread on a code of conduct for arborists re this issue, more info in there.
