Cedar tree dieback

[hamdogg]

Hi all, any ideas on what could cause this? My client says it's happened all of a sudden!

 

 

Life's all about moving forward, you learn what you can and crack on!!

Sirococcus maybe? (see p.11 of attached)

 

Cheers..

Just waiting for a confirmation from the FC for the same. Pretty rife around here

[Island Lescure]

Seen a few like that around here just recently.

I know of 3 within a mile of each other in South Cheshire too.

Lots of deodars dying round here. Good money maker if I'm honest!

I saw a couple last week, mature ones, south of cheadle and wilmslow. Apparently a lot down around Nantwich too

Got this back from the FC today, in response to some samples they requested and I provided about ten days back:

 

We have now completed our test on the Atlas cedar and it tested positive for Sirococcus tsugae.

 

There are no effective control measures for the disease. While good hygiene may reduce the spread of the disease, conidia of the fungus are dispersed by rain splash and strong winds are likely to disperse them over longer distances. This is a disease that was only detected here in Britain two years ago and we are still monitoring how it progresses. The fungus can cause up to 70% defoliation and if the cankers affect the main stem (and it is girdled), the tree might die. We had only a few reports of young trees dying.

 

It seems to widely distributed locally for such a short time since it was detected in the UK.

I have seen 2 in the last month, notified the FC. Onset seems pretty rapid..
