Thinning and Pruning Western White Pine: A Potential for Reducing Mortality Due to Blister Rust

摘要

Thinning and pruning were tested as potential methods for reducing mortality of western white pine (Pinus monticola) infected by the blister rust disease caused by Cronartium ribicola. Five years after treatment thinning had increased the number of new lethal infections per tree. Pruning counteracted the effects of thinning.
