Welcome to yet another page devoted to daylily rust. I've accumulated
a few things that might be useful to others and decided it was time to
make a page so it would be easier to share. As I get
my hands on more data and have time, I'll add to the page. If what you
are seeking isn't here, please try Sue Bergeron's page. It contains
many more links and images.
Something New, But NOT RUST
This spring I noticed the following raised orange spots on a
section of my daylilies. When I rubbed them with my fingers,
they came off -- completely! In those moments between first
spotting this and examining it more closely, I thought it was
rust. After realizing it was not, I figured that if it fooled
me, it could fool someone else. But what was it? A trip to
visit an entomologist at the NCDA with a much better microscope than
my own finally gave me the answer. SEEDS! What kind, I still

2002 Region 2 Winter Symposium in Ohio
While I was unable to attend the Region 2 meeting, Kaye Arnold
went and recorded Dr Nameth's presentation on rust. My notes from
that recording are available following the link below. Unfortunately,
I do not have slides from this talk.
"A Pathologist's Perspective on Daylily Rust" presented by Dr. Nameth
Mid Winter Symposium 2002
Dr. Williams-Woodward's slides from her MWS presentation are now available.
Due to the size of the powerpoint file, I'm not making that version
available at this time. Contact me or Dr. W-W if you should need it.
Dr. Buck's MWS presentation slides, which he graciously sent to me with
permission to post, can be found below.
Region 15 Fall Meeting, 2001
Region 15 was fortunate to have Dr. Williams-Woodward give a
presentation on Daylily Rust and the research being performed on it at
the University of Georgia. I am pleased that she graciously shared her
slides with me and gave permission to post them to the web for those who
could not attend. The slides are available as web pages suitable for
two different screen resolutions and a downloadable Power Point file.
My notes from the meeting are also available.
"Daylily Rust in the United States" presented by Dr. Jean Williams-Woodward
Earlier this this season, I photographed daylily rust side-by-side
with other damaged leaves that might have been mistaken for rust.
Click on the images below for a larger version.
The image left shows one leaf with the early stages of daylily
rust and another which is suffering from leaf streak. Note the
dark speckles within the yellow area on the one with rust.
The images to the right shows the back side of the same
rusty leaf compared to
one which is has some insect damage. The insect damage
might be thrips or spidermites, but part of the damaged area has
become infected with leaf streak changing it from the usual silver
to a rusty brown. Note that the insect damaged areas are roughly
rectangular and depressed while the rust is round and raised.
