Sick Apricot tree: damage visible on bark

I'm going to duplicate a post in the Garden Clinic. A friend has a sick tree and she'd like to act immediately to save it, if possible. I link to the other post at the bottom, so that nobody duplicates any effort.


Hi,

I was just visiting a friend in Palo Alto, CA. Leaves on one limb of her Apricot tree are wilted. Damage is apparent to the bark on this one limb (photo). The bark is split and is separating from the underlying wood.

1) What is this disease likely to be? If there is more than one possibility please describe how to narrow it down.

2) Can the tree be saved, perhaps by removing the infected limb?

Damage is obvious only on the one limb, but it's not clear we know precisely what to look for.

Thanks.

I'd might just cut out infected tissue into good bark, disinfect
your knife one's in a while and paint with similar color, brown
latex paint. See how it will do over time, if it gets worse then yes,
cut off that limb.

There's a good chance this is bacterial canker or Eutypa dieback. If there is a dead limb I'd remove it but not now. Wait until the driest part of summer, say August. For further info UC Davis is your best source.
