Need Help to Save My Peach Tree (11 Years Old)

Question

We moved our donut peach two years ago but pruned too much, some almost 1 inch diameter. Last year two branches died, and this year all four major branches died—-no leaves, has one small new branch in the end, with some holes in the big branch close to the trunk. Is this brown rot? How do I save the tree? We still got some peaches this year. I checked the web, there are holes on the branches, and it may be the peach tree borer. Your help will be very much appreciated. Victor

This is very possible. This article will help:

I would also recommend that you treat the tree with neem oil. The neem oil gets inside the tree's system and will kill pests that other insecticides can't reach.
