Whats happening to the tree"s? (1 Viewer)

[Steve Napier]

Hi.
Ive noticed just recently that ALL the sycamore tree"s here in Newcastle are absolutely covered in what looks like "white chicken-pox"on the bark and branches, I pressume its some type of fungus,its not just the sycamore tree"s either,although they seem the worst affected.
Can anyone give me a definative answer as to what it is and,will this kill the effected tree"s off?
Thankyou
Steve.

Sounds like cottony cushion scale, not a fungus but a type of scale insect. I've seen quite a bit this year: I guess they like the weather we've been having. A heavy infestation will weaken the tree and could theoretically kill it, but it's unlikely. However, if you get them on your fruit trees then you could lose some or all of your crop.

Thanks lads.
Yes,it does look like cotton,with a brown disc on top {similiar to the eye you get on willicks}.
Some of the trees Ive seen are so heavily affected,you cant see the bark.Very worrying.
Thankyou,
Steve.
