Peach Tree Help
I am at my wits end on this tree. First it started with leaf curl 5 years ago. Now its starting with spots and white fungus. We have had a very wet year so far and I think the white fungus is from this. I have been spraying it down with Bonide 811 Copper 4E Fungicide before and after the seasons with no luck. I am seeking help as I do not know where to turn to. Here are some pictures in my google album. If you are unable to help, do you know a good forum I can use for fruit tree help? https://photos.app.goo.gl/3vbMJTGeCYRa2JXcA

I viewed your photos. The leaves have a fungal leaf spot. But it could just be on older senescent leaves, because in the photo of the whole tree the foliage appears relatively healthy. If it's only a small percentage of foliage infected, then its not a big concern. 70% neem oil or a biological fungicide spray every two weeks during the growing season may help with prevention. Use the copper during the dormant season.
The white growths on the trunk appear to be fruiting bodies (like mushrooms) from a fungal infection of the woody stem. I don't recognize the specific identity, but it appears to be associated with old cuts or wounds. So there could be internal wood decay, or it could be rather superficial. Lawn irrigation is often too much water for a tree and can cause crown rot that can advance up in to the tree trunk. If you favor the tree, I would suggest that you sacrifice some lawn area and widen a mulched open soil surface for the tree root zone that only gets weekly water, not daily.
I'm not sure about the mutant growth on the leaf; it could be a remnant from the peach leaf curl but I don't see the characteristic discoloration. Or it could be a virus. If it is not affecting a large percentage of the foliage, I would say pick them off and don't worry too much about it unless it spreads to more foliage.
Thank you. The white fungus is also higher up on the bottom of branches that are healthy and not cut. So I think its crown rot then. Thank you for your advice.
