I’m in a similar boat, though due to my own selection. My disease resistant variety (enterprise apple) ended up getting grazed by deer too much and died over winter a year or so back. I wasn’t able to find information about CAR resistance on some of the varieties I’m growing so I rely on spray over genetics.
Like Blueberry said, none of them seem to suffer so much as to be in any danger. So far my experience with CAR has been:
Crimson Crisp - Susceptible
Winesap - to new
Airlie Red Flesh - to new
Era Redlove - way to new
Granny Smith - Susceptible
Chestnut Crab - Resistant
Honeycrisp - Susceptible
I’m trying to get mapped on here so I can compare what others in my area are experiencing and growing:
