Are any studies of daylily rust currently being conducted? Has any University done any studies in the past few years checking for rust resistant cultivars? Have they given up on it as a hopeless task? Do they feel rust is pretty much under control? Do they feel chemicals are the answer?
I don't know the answer to any of the above questions there seems so much still to learn, but maybe there is just no money set aside for research.
If a plant (this is all hypothetical) showed no rust, yet all plants around it did in my garden, and that plant was rated as "Shows Susceptibility" in other gardens, why would I not be just as justified in changing that to "Shows Resistance", as opposed to the other way around?
I agree one garden is not a reliable source either way, and it looks like to me this rating done in this manner just toggles from the rating of one garden to another instead of taking all the ratings for one plant from all the gardens and using that to develop a rating. Yet, I do wonder how many times this has actually happened that the ratings were switched?
