Rust Fungus on Black-Eyed Susan

Orange Pustules = Fungal Rust

Leaves turning orange-rust color and crumbling at touch indicate rust fungus. Remove all affected leaves immediately.

Treatment

• Spray with fungicide labeled for rust on ornamentals.
• Improve air circulation.
• Avoid overhead watering.
• Clean up all debris in fall.

Rust spreads via spores; sanitation is key.
