- Rust is caused by the fungus Puccinia asparagi
- Rust is only a problem on fern … not the spears
- Infected fern is defoliated reducing future crop yield
- Rust infections begin in Spring from spores on crop debris
- Look for early signs of rust and apply
fungicide controls
- Remove volunteers as sources of spores
- Spores can be spread on clothing and
equipment
