Fungal spores are released when the foliage is wet and are spread by splashing water. Water early in the day so leaves can dry. Keep plants as well-spaced as possible to increase air movement around plants. Several different fungicides are labeled for leaf spot diseases including thiophanate methyl (Cleary's 3336 or Fungo Flo), myclobutanil (Eagle), or chlorothalonil (Daconil, Pathguard) or azoxystrobin (Heritage). At the end of the season, remove infected leaf debris. Do not confuse this fungus disease with Daylily Rust. |
