bacterial cancer in moorpark apricot - solutions?

I transplanted a three year old tree and espaliered it against a fence 2 winters ago. shape pruned it in winter, thinking i was being very sterile.
Now sudden death of limbs, gum exuding.
Should i prune off the affected parts, pull the tree, or spray with something?
Any advice?

Apricots seem prone to this. If you think you might retrieve some good limbs, I'd give it a pruning, but my experience is that once they start exuding gum, there is a bif chance that diseases, canker in particular becomes systemic and the tree will die. If you plant another put it in a different place.
