Abstract
Four host-susceptibility zones based on elevation and climate were delineated. In zone 1, less than 5% of white pine stems were affected even without Ribes eradication. The level of infection remained lower than 15% in most plantations in zone 2. Recommendations based on recent studies are made concerning site selection and protective measures. Studies of meteorological data and of recent and earlier disease surveys confirm the validity of this approach to the white pine blister-rust problem.
