Chalara fraxinea - Generic thread

[arbogrunt]

a mate of mine visited a predominantly ash wood in Essex and the Chalara is very bad in there. He said there are lots of secondary fungi getting in there as well, mainly Innonotus Hispidus. He's also notice lots of similar die back in Field Maple in the same wood, anybody heard of anything similar?

An outbreak of ash dieback (Chalara fraxinea) has been confirmed in the National Forest near Ashby-de-la-Zouch, Leicestershire.

 

The Forestry Commission has identified the disease on 17-year-old and five-year-old trees

Came across this tree in a plantation-strange discoloration on bark.

Is this chalara?

Hello Lumberlover welcome to the site.

 

personally I would think it difficult to asign an identification of Chalara based on one single image.

 

It does seem to show a diamond type lesion on the trunk which is thought to be a symptom.

 

My advise would be to send an enquiry into........

Flicking through a copy of the posh hunting magazine 'The Field' last week, I came across this letter from a reader claiming he had 'cured' his Ash from Ash dieback!

 

I suspect that perhaps the tree didn't actually have Chalara dieback but it did make me wonder if anyone else had heard of any successful treatments.

Lumberlover, may well be a target type canker caused by phytophthora either with or without the presence of chalara. Definitely contact FC plant health as David suggests, as depending on your location you may have only the second incidence in the country of this.

This short report on which fungicides were successful via foliar treatment may interest you Paul if you've not seen it, hopefully there will be similar success with the stem injection trials.

The photo shows chalara tree trying to callus over damage, multiple epicormics coming from above and below which are also infected.

 

Trees have good and bad years with this disease, I do not believe the letter too much Port whilst out hunting.

Forgive me for not having read the entire thread to see if this has been mentioned previously, just wondering if anyone has either accessed any research papers or considered a field trip East to have a look at how things have panned out in the areas that had the disease 15-20 years ago? It could be a cracking long weekend or short week field trip if well organised and a bloody good shin dig - and tax efficient!
