Peach tree problems
Thanks for writing. Without being able to see your peaches in person, I can't say for sure what the problem is. I'd suggest you contact the folks at your local county extension office or your local garden center --- they should be able to help better if you can talk though the situation (tell them what the varieties are, what specific fungicide you sprayed, what the growing conditions are, etc.).
