Last week I described the problem:

I have a fully grown, 25 year old ash tree. A few years ago some crunchy,
crab-apple type growths appeared on some of the branches. I must say I
didn't pay much attention, but last year a significant amount of the tree
was covered.

When removed, these growths crumble into small pieces. They are dark brown
in colour. The tree seems healthy otherwise.

I'm in Canada, Southern Ontario. I'd appreciate some advice on what is
happening., and what I can do about it.

Thanks,

George

Sed5555 gave me the following link which seems closest to what I'm seeing:
http://www.colostate.edu/Depts/CoopE...ests/galls.htm

I don't think it's the ash borer although I am in the affected area (1 hour
from Niagara Falls).

If it is a gall of some sort, Sed's link suggests just leving it alone, but
it dowsn't mention whether it resolves or persists. The leaves seem
unaffected.

Can anyone give me more information?

Thanks

George

George: We were all wrong, and I should have picked up on it!!! We have the
same thing in the NE use. This is not a gall on your tree, there are no
insects or mites at work (of this I am certain now) - it is instead aborted
flowers that have been infected with a bacterium or virus (I forget). In
some years it is worse than others, and it is just part of a nasty menu of
afflictions that ash trees are ordering from these days.

If I recall there is nothing you cab do about this, just let nature takes
it's course.

Oh, whither the poor ash tree species!

So my tree has the flu!

Do trees make antibodies? Will it recover?

This virus/bacterium must be species-specific. There are two maple trees, a
sunburst locust, and a privet hedge close by. There isn't a single lesion on
them.

Thanks Mike.
