I think mistyfog makes a good point. When rust broke out in 2001 almost everything here had it, now I see very little each year. I import a lot on new daylilies each year from all over the country (115 this year) and none have any signs of rust. As warm and damp as it stays here with no winter to kill it something good must be happening to the daylily. This pass fall I only saw rust on two plants, with 6000 seedlings and 500 registered plants thats a large improvement over five or six years ago. Even though I spray I can see a big difference in rust resistance.
