Powdery Mildew - apples

I grafted a single spur of Roter Ananas onto a half-standard of a different variety about 4 years ago to evaluate this variety, but every year it succumbs to powdery mildew just as the fruit sets, just about the only apple cultivar I grow which suffers. The parent variety is completely unaffected.
