It looks like it, after some research ,the chances are not on my tree's side. I'll try to cut off the infected parts completely and use a copper fungicide, web sais it helps sometimes. I just have to wait a little since were in a non stop rain for a week....
Bad news is i see similar sap oozing directly on the graft parts of the varieties i top worked the tree with , a year ago. ..nasty stuff indeed...
