Borer-resistant apple variety

12 years ago

My Etter 16-32 (Thornberry Crab) makes a big glob of sap at every pruning cut. It is a very vigorous tree (even on Bud. 9) and is one of the only ones in my orchard that has not be hacked by borers. Could it be that it successfully saps out any attack? Sunburn doesn't seem to bother it either.
