Here are a few of my Harrelsons. I spray an all purpose formula on them every 10 days. But about 5% have these scars.
What is this? And how do I stop it?

I had that problem on a spy tree one time and couldn't get rid of it. I gave up on the tree. I don't believe the home sprays available do much for anything. If they did you would have to have a permit to use it.My son has faithfully sprayed my few trees the past few years and the fruit still looked diseased. We haven't sprayed once this year and the all look good.

I have sprayed the trees and ground under them every 10 days since mid March.

Fruit cracking is not generally due to disease so much as weather conditions. Anything from high heat and drought to high humidity and too much rain can cause cracking. Some older varieties such as Stayman-Winesap and Russet are susceptible so maybe is yours. You schedule of spraying sounds about right altho check your product label as sometimes use of one pesticide/fungicide for too long can also cause issues.
