Paul,
Try Maple Valley Orchards @ www.maplevalleyorchards.com Tony Dembski, the owner, is very helpful and will take the time to listen and offer suggestions. He taught me how to graft my own fruit trees which I love to do as a hobby. I'm not sure you're going to find any thing that is not bothered by the Japanese Beetles since we have them here in Wisconsin too.
Good luck,
John

I need a recommendation for a fruit tree that is not bothered by Japaneese beatles and is relatively free from fungal infections. This is for Central Maryland - zone 6

thanx
