Welcome here @NorthOzarksMO
I am a no sprayer myself and have hoped for even a low spray all organic solution that I could do just a few applications of and get nice clean peaches…
But evidently that is a dream that just does not come true.
I have 3 peach trees and do not spray… and between ofm and brown rot… well it is just quite disappointing.
I do however get some nice clean peaches on my Early peach tree… ripens mid June… some… not all. I am going to try an even earlier variety next to see if that will help more. Rich May.
My later peaches… well BR and OFM get the bulk of those.
If you ever get frustrated with all that and the sprays needed to get good fruit from things like peaches cherries etc…
You might replace your most problematic varieties with some of the recommendations in the post… link below. No Spray Fruits.
Good Luck to you !!!
Early Elberta peach June 22 last year… no spray no ofm no br. Unfortunately only a few were that nice.
