Hi Michael,
I've considered this. While most trees are growing in grass verges which they
share with numerous services they're one or two on wider open space. I was
wondering if anyone had had any success with Verticilliun through treating
the rooting area?
Best regards
Phil

Why not think about improving sol conditions by aeration, mulching etc.
Maybe a trial of a few.
Since Verticillium is often associated with poor soils that might be a
place to start.

Thanks Ian,
My client is a Local Authority and the trees are street trees. Infection
is such that any pruning of diseased branches would massively affect the
amenity of the trees. V.dahliae, being a soil borne fungus, spreads quite
easily among this tree population as there's reasonably heavy footfall.
They may have to bite the bullet and fell & replace.
Many thanks

Understanding how trees become infected with this disease, the vector and
how its spread might help with a plan of action.
With Elm disease cutting the branch with symptoms (discoloration of
foliage/shepherds crook) deep below the visible disease into clean wood
with wounds showing no staining should arrest further ingress.
I hear someone recently had lopped the top of an Ash tree with Chalara and
appeared to respond well with new growth, albeit looking somewhat different.

Hi all,
Does anyone know of any effective control measures for Verticillium
dahliae in Norway maples other than pruning out the deadwood?
I have a client with 150 Norway maples of which 60 have symptoms of
V.dahliae to some degree or other. I'm looking for an alternative to
felling. Best regards
Phil
