What Is the Disease on My Peach Limbs

Question

There are tiny, little purple pus-filled balls that attach at crotches and underside of limbs and at new to old growth. It destroys (ages) bark and left untreated, the leaves get sticky and wet looking, branches will get girlded and die. The only treatment I know is to physically remove with a small brush and sulphur powder to dry up (every branch on entire tree). It eventually kills tree. What is this stuff?

Answer 1

I have to say that I am stumped. I have not heard of this before. I would recommend taking a picture of it to your local extension service and have them take a look.
