Greg, look for curl leaf resistant peach.. don't bother with 'averages', I am so sad, my trees were so beautiful (3 y.o.) and this year..they are so 'sick' with this nasty fungi, I have to figure out how to treat them this fall to see if they can recover. Seems like my Frosty was the one one that was spared. so maybe that is a good one to have.
