Thank you to everyone who is chiming in here on all my questions!
I, too, had not heard about the rust supposedly going dormant when the temps are over 90. (Or do the high temps actually kill the rust spores?) If anyone has a link to more info about the heat factor, I'd sure love to read it! I am not so sure whether it is true or not. But I will definitely be checking that out since my front yard, full-sun daylily border gets VERY hot in summer.
I probably have everything a daylily could be exposed to in my garden beds! LOL! Since I know so little about disease, fungus, and pests and I garden organically.... well ... I am just going to post photos and I would love for those in the know to post comments about any or all of my photos to help me determine what each of the issues are per photo. Does the plant have rust, leaf streak, thrips, other pests, or what??? ....
This is a cross of Stippled Statement (I am pretty positive, even though I wasn't able to keep track of this one and most of my 1-2 year old seedlings). I have been reading that many of the stippled blooming daylilies are showing some resistance to rust. Of all my seedling blooming this year, this one is by far my favorite. Beautiful and abundant blooms! Foliage is not a rust bucket yet either.
Here is a close-up of one of the older leaves from the A photo plant:
Is this what normal die-back looks like on a leaf?

This plant has rust. But what about all the brown leaves around the base of the plant? What's going on here with this daylily?
Is this leaf streak or normal die-back?
Two photos showing streaking in some of my daylily plants leaves. Is this leaf streak or something else such as a deficiency?:
2 Photos. Normal die-back of the leaves or something else?
Normal die-back, too much water, or what is going on with this one?
This is what a "rust bucket" daylily looks like:

What is this? Normal die-back or leaf streak?
This is showing a moderately resistant daylily plant. The plants around it are showing a LOT of rust damage. This is showing far less rust and damage!:
These two daylily plants are showing a high resistance to rust. You can see the rust buckets around them! Little to no rust on either of these daylilies:
Would really appreciate feedback on these photos as to what you think might be going on in the photos! Thanks so much!
