For the first time, this year I have a similar problem.
I have had multiple pruning wound infections (black discoloration and
no callus, dependent (proximal) to pruning cuts) this year - apple, pear
and kiwi! I don't know if it is the same thing as you describe. I sent
kiwi tissue samples to the plant pathologist. They were able to grow out
fusarium (as I recall) but labelled it a probable saprophyte and
probably not the cause of the initial lesion.

The wounds all have new shoots coming out in great health, and aside from the black color all appears fine. Is it mildew?
