Tina - Thanks for that link!
I do know what rust looks like. I definitely have that on many of my daylily seedlings. It is what it is. It doesn't kill the plants and usually doesn't seem to affect the blooms. So I don't get too concerned about it. Since I don't sell or even share any of my daylilies, it's not a big deal (to me). The only way I am going to figure out which daylilies seem to have some resistance to rust is to grow them all together. Some daylilies have minor rust or even none at all. Some are rust buckets!
Okay, looking at the photos on that link .... I believe I do have Leaf Streak on some of my daylilies. Some have both leaf streak and rust. Ha! Not keepers, but instead only used for exposure to other dayliles to determine resistance. Now my question is how do daylily leaves look as they are dying? Does Leaf Streak get brown spots like rust, but not orange spores like rust? What I am seeing is actual streaking of the leaf. Like over-watering it or it is drying out and turning brown. Which is why I am confused about dying leaves and leaf streak. I can't tell which is which ....
