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.
