I located a overgrown field near me (not mine) that is filling in with Bradford Pear and Russian Olive. I plan to graft some late-maturing pears onto the Bradfords. As well, I want to drop some late-maturing apples in the area too, either through a Winter Banana intergraft to the pear or directly on M7 rootstock (union planted below the soil line for a taller tree). Needless to say, I will not be spending too much time on this property to care for the trees (spraying, pruning, or thinning). I am looking for late season apples that would give me the best chance of collecting fruit in October or November in Northeast Pennsylvania. I recognize that I may end up with a small fraction (if any) crop after the diseases and critters take their share. Below, I have done my best to categorize late apples by disease resistance. However, some of the varieties are obscure or new enough that there is not too much info available. I have not listed a few varieties that I already have in my backyard orchard (Newtown Pippin, Gold Rush, Arkansas Black, and Suncrisp). Please comment to agree or disagree with my disease classifications below:

My backyard orchard is in similar area to this abandoned field and I would suspect similar disease and insect pressures: Scab, powdery mildew, curculio, and codling moth being the prime offenders. I do not think there are many cedars close to this field and I have not yet had an episode with fireblight after 6 years.
Thanks in advance for your collective wisdom.
