Subject: [CANUFNET] Oak tree top dieback

Hi everyone 

I'm visiting family in Windsor Ontario and my aunt has a  Quuercus robur
'Fastigiata' The top is dead from the top to about one meter from the
ground.  The tree did non leaf out this spring except for the bottom meter
of the tree. I know the weather  has been wet in the summer in the Windsor
area the last few summers. I believe it is anthracnose or oak wilt. It looks
like anthracnose but not sure if the disease would cause 80% of the tree to
die. I suggested to prune the dead out and let the tree grow from the base
but if it is oak wilt I don't want it to spread to there other oaks. Has
anyone else had this problem in the area from the wet weather. Or dose
anyone know what we are dealing with. The picture is a few leaves from the
part of the tree That did leaf out this year and the disease is only on
about 10 % of what is left alive.
