Hosta Diseases and Pests: Diagnosis Guide from UGA and Iowa State

Hostas are shade-garden workhorses, but they face a roster of foliar diseases, viruses, and pests. A joint publication from the University of Georgia and Iowa State University provides clear photos and descriptions to diagnose:

• Anthracnose, botrytis, and other fungal leaf spots
• Hosta virus X (HVX) – the most serious viral threat
• Foliar nematodes – causing angular, vein-limited lesions
• Slugs, deer, and vole damage
• Crown rot and root rots
