The cold winter of 2014 seemed to really deter the rust in my garden, and all through the spring and early summer rust was not a problem. Only later in the season ... almost after the season, the rust was able to get established.
The past two years I had a hit and miss type of rust spray program not sure it really did much good. This year I only sprayed one time and that was with a mixture of dish detergent and immunox(or daconil) can't remember for sure. At least in my mind that did a little good, only a few of the daylilies were showing rust at that time. As the weeks passed more and more of the plants became infected. But it was a very gradual thing and because of that I never did spray again. So the plants pretty much cleared themselves of the rust. When I walk through the garden I can still see some signs of rust, but those leaves seem to be dying off by themselves, and with this beautiful weather new green healthy leaves have been replacing them.
I want to comment on new plants brought in that show rust almost immediately. I am not sure that the new plants are bringing in the rust, or that those plants have no immunity to the rust that is present in their new surroundings. I have had several plants that during their first season showed rust, then they did not show rust after that to any major degree. Do they build up a tolerance? I don't know, did the weather conditions have to be just right for them to get rust? All I know is that I would not get rid of a daylily for at least a couple of seasons just because it showed rust, because I believe some of them might never get rust again, or at least not on a regular basis. I am not sure any plant has been checked to see if it consistently got rust for several years in a row, or did not get rust for several years in a row.
