No problem with this topic!
I had rust in my garden in 2001, and have not had it since. Back then, there were a few daylilies that did not get it. Spoons for Escargot had plants all around it with rust - and their foliage was leaning over SFE and yet it never did get any rust. I know there were a few others, but I don't recall the names.
I have not done anything to prevent it, just has not showed up. If it did, I wouldn't do anything about it because our winters kill it.
