Ribes Species as White Pine Blister Rust Hosts

Primary Alternate Hosts

Ribes lacustre, R. nigrum (black currant), and R. viscosissimum are most susceptible. Most pathologists consider all Ribes potential hosts.

Regulatory Landscape

Federal ban on black currant lifted in 1966, but many states retain restrictions. Resistant cultivars (e.g., 'Consort', 'Crusader', 'Titania') are legal in most areas.

Nursery Advice

Sell only rust-resistant cultivars.
Check state/county regulations before stocking.
Avoid planting near 5-needle pine nurseries or high-value stands.
