Examples
- The blister rust disease has been a major threat to the white pine population in the region for decades.
- Foresters have been working to develop resistant tree varieties to combat the spread of blister rust.

- Researchers have identified several species of Cronartium that cause blister rust in different types of pine trees.
- The introduction of blister rust to North America in the early 20th century had a devastating impact on the native white pine population.
Synonyms
Meaning 2
Fungus causing white pine blister rust and having a complex life cycle requiring a plant of genus Ribes as alternate host.
Classification

Examples
- The complex life cycle of the blister rust fungus involves a primary host, typically a five-needle pine, and an alternate host from the genus Ribes.
- Cronartium ribicola, the blister rust fungus, infects and damages trees in the white pine family, and efforts are made to eradicate the alternate host, currant and gooseberry bushes.
- Infected white pine trees may take several years to die from blister rust, a disease caused by the Cronartium ribicola fungus.
- A plant from the genus Ribes, often currant or gooseberry, is necessary for the blister rust fungus to complete its life cycle and produce spores.
- Researchers study the life cycle of blister rust, including its time spent on alternate hosts from the genus Ribes, to find effective ways to manage and prevent white pine disease.
