What is killing my peach tree

Question: I planted my peach tree in April 2022, I Purchased 2 bare root trees from Washtenaw county Conservancy. 1 came with a broken root and a small top branch was dead. I pruned both. I planted it,  seemed to grow well until this spring, started to die on the top and bark separating on the trunk. The rate of acceleration now is that it’s killed 2/3 of the tree. The bark seems to be peeling off and there are many orange gel spots. The other tree I purchased had 11 peaches and is doing great.

response: Really can't tell from this picture what killed the tree.  Often it takes an examination of the whole tree.  I recommend you split the tree branch lengthwise to look for internal insects, or other damage to the interior.

response: The bark is peeling off the tree, IMO that is indicative of borers. The bottom three branches of the tree are still living. BTW this bare root peach came from Washtenaw County Conservancy like this. Is it salvageable? What organic spray can I use? Should I just dig out the whole tree and toss it. This is only my second year of organic Permaculture farming. I have many fruit trees,  in the spring I am spraying Pyrethrins. Will this help? I have plum curculio in my cherry plums and peaches.
