Widespread daylily problem
I'm wondering if anyone else is having a problem with this yucky daylily disease this season. I think I noticed it in a photo someone else had posted of their garden, but it was hard to tell. Here's the description from the UofM:
"Leaf streak, caused by the fungus Aureobasidium microstictum, is the most common foliar disease of daylilies. Although other leaf spot and leaf streak diseases do occur on daylilies, it is unclear whether any of these problems are caused by fungi.
Aureobasidium leaf streak causes elongate brown streaks and yellowing of leaves.
Infected leaves initially develop water-soaked (dark green) spots, which later enlarge and brown, forming streaks along the midvein of the leaf. Severely infected leaves will turn yellow. Often, the inner leaves of the clump, where conditions are moist, are more seriously affected. Finally, the fungus produces black seed-like structures, called sclerotia, on dying older leaves. These structures survive winter and cause new infections in spring."
I've never seen a plant problem so widespread this year. Many of my plants have it. I've noticed it other people's yards across the city and in public plantings. I even saw a lot of it in a city 70 miles north of me.
How about everyone else?
