Paul Robeson Tomato

3 summers ago I had an amazing crop of heirloom tomatoes.

Plenty to give away to friends. the last 2 years powdery mildew has destroyed my poor tomatoes even though I worked hard spraying with anti fungal and taking off diseased leaves.

No mildew disease resistant heirlooms that I can find and I am worried I get the mildew again this year.

Know of any?
