Peach Tree Sap? #434317

Good Morning , I was out looking at my peach tree this am and noticed that there is a bunch of brown gel/sap like substance coming out all over the tree. It started life as a nectarine tree but the deer girdled it and it came back up from the root stock(one section stayed as a nectarine but think I'm going to prune it off it is the last picture actually) and usually produces really good peaches, just late in the year end of sept. This year they never really ripened all the way. It does have leaf curl which i intend to spray for here in a month or so.
Thanks, Doug Baxter, Pilot Rock

I believe you most likely have a gummosis disease caused by Pseudomonas syringae. https://pnwhandbooks.org/plantdisease/pathogen-articles/pathogens-common-many-plants/bacteria-other-prokaryotes/diseases
