Title: Re: [NAFEX] Gummosis on apricot
That sounds like Pseudomonas.  We get it in Oregon all the time.  The only thing done for it here is to cut off any dead limbs.  Any gummy spots usually heal up as the summer warms up and dries out.  Apricots are mostly pretty susceptible to it, so they may suffer rather badly.  Other prunus may get an occasional canker, but usually it's not serious, though it will girdle small diameter  limbs.

I was walking by my largest apricot tree recently.  I noticed that the lowest branch's leaves were wilting.  I looked closer and notice that at the base of this branch was significant gummy residue from the bark.  There was also gummosis extending up the main trunk from this branch.

Should I:
1) Do nothing (except remove branch once it dies).
2) Remove branch.
3) Remove branch and strip bark from gummy area on main trunk.

Let me know your thoughts/experience/knowledge regarding this.
