Introduction. White Pine Blister Rust (WPBR), caused by the fungus Cronartium ribicola, is one of the most important diseases of white pines. C. ribicola infects white pines and Ribes spp., causing severe long-term damage and disruption to ecosystems by altering patterns of natural. White pine blister rust, a widely known tree disease in North America, is caused by the introduced fungus Cronartium ribicola. C. ribicola is a.
