I wonder if anyone is familar with this type of disease is it a type of canker? Seems to be a problem with bare rooted weeping acer palmatum, in the trunk not so much the twigs. Vascular tissue goes ~black and gets worse untill tree dies...

RE: Japanese Maple dieback disease pics

I have seen something similar in fruit trees - my apricot, and also in my sisetr-in-law's weeping cherry. Her cherry died, my the apricot lost a few branches and is doing OK. Here we have had silver birch trees and london plane trees effected by some kind of virus which kills off smaller branches. The first thing you notice are leaves turning brown, then the branch dies back to the stem of the tree. The disease in the apricot looks similar to you dieback diseas, but as the bark is brown and rough, the blackness can't be seen as easily. My theory is that it is stress from hotter/drier weather.I haven't touched my trees - not cut back anything or sprayed, preferring the 'wait and see' approach. So far, they are holding up...
