Our two back yard peach trees are about 100' apart. They both produce but fruits reach approximate size of a walnut before development is arrested. Peaches that fall off taste fine at that point but not enough flesh to justify processing. Some dried, hard, brown fruits remain on tree through winters. Leaves appear healthy, although woody parts of trees seem darkened with some green splotches. Suspect a fungus but not sure. Two years ago I planted a 10' apple tree about 25' from one of the peach trees and by the beginning of the following growing season the trunk had turned black and the top died. I'm trying to raise a sucker off of it now. Attaching photos hoping for a solution.
Unfortunately, your photos did not come through. I am unable to see the damage. It does sound a bit like an infection has taken over in your area. This can happen in areas that have poor drainage, or wet areas.
You can try general fungicides, but I would take some samples and photos up to your local extension service.

This will help you with fungicide use:

Generally, once the soil is dry down to about 4 to 6 inches, you will water. The frequency will depend on the conditions around the tree at the time.
I have added chelated iron and sulfur to our alkaline soil to try and combat what I originally thought was chlorosis. I have little to no results from this despite a second treatment following all the directions. Is there any other disease of peach trees that can be causing the leaves to turn yellow then white before they fall off?
Here are some possibilities:

My contender peach tree arrived today on 8/5/2021. It appears ill with brown spot disease. Pictures attached
It looks a bit stressed and damaged by insects, but t doesn't look to be so bad that it will fail. A fungicide may help, here:

I have a porch peach tree that now looks very sad. One day went out on porch to look at the peaches. GONE and not on ground. It couldn't of been deer since porch upper level. Now day after day less leaves and the leaves still present are full of eaten holes. The tree is still getting new purple color leaves. I moved the porch peach tree to the front porch but problem still happening. I have found grasshoppers and another bug that I can not ID. I put Sevin Dust, diatomaceous earth, coffee grinds, garlic and red pepper, neem oil, nothing has stopped the eating. Only about 5 leaves on end of each branch. My question is: will my poor little porch peach tree next spring have leaves on the entire branches? Is there anything I can do over the winter to give it a healthy new start. I live at the Lake of the Ozark in Missouri. The past winter years I left on porch just covering when frost was forecasted. Thank you
If it is insects and not disease responsible, it should leaf out again in spring. Be sure to prune it. Here are some growing tips that may help:
