I have a peach tree that has sap on the stems and fruits. This is the second year for this to happen. What is it and how can it be controlled? It was first on a plum tree that I removed and now on a peach tree. I also have 2 more trees that I had planned to set out in this area. Should I do so?

It sounds like it may be peach borer, which attacks all stone fruit trees. This article will help: https://www.gardeningknowhow.com/edible/fruits/peach/peach-tree-borer.htm
I too, have this problem on a plum tree. It is on the bottom near ground level.I think my husband hit it with the line trimmer. The tree did also die. I have a weeping willow with the same problem. Same reason. He said it was caused by bugs.
