Java......Rot is the worst thing for daylilies, its the only thing that will kill them. I consider snails and slugs to be next, because they eat the blooms. Thrips aphids and rust are annoying. Thats how I see it, but I dont sell daylilies, and I realize there are some that get really whipped up over rust. It is ugly, it does make the leaf die back and makes the plant in general, not attractive, thats why I try to keep up with it. I would not loose any sleep over it, but it sure doesnt make good eye candy to go along with the flowers. The smaller/weaker/newer the(sdlg) the plant, for me, the more likely to have rust. I do have a couple of big boys with some, but it doesnt seem to spread.
