Technical Abstract: A large, established landscape collection of 575 newer cultivars was evaluated for daylily rust which had not been sprayed with fungicides to prevent infection during 2013. The warm, damp summer of 2013 was ideal for spread of daylily rust. A total of 119 of the 575 cultivars received a median rating of 1 or 1.5, indicating the possibility of rust resistance; however, some of these cultivars may be more susceptible to the disease than a single-clump rating might reveal. These cultivars are worthy of continued evaluation for resistance to daylily rust. Use of rust-resistant daylily cultivars in the landscape can help to reduce the time and expense involved in repeatedly spraying daylilies to prevent rust.
