Iris leaf spot: Remove and dispose of affected foliage at the end of the year and maintain good garden hygiene.
Bacterial soft rot: Ensure well-drained soil and plant rhizomes partially exposed to prevent waterlogging.
Iris rust: Pick off lightly infected leaves to slow spread but avoid removing too much foliage.
Ink disease: Dig up and destroy affected plants immediately; do not replant bulbs in that soil for several years.
Virus infection: Remove infected plants to prevent spread via aphids or contaminated tools; use virus-free stock.
