Preliminary Report on the Relative Susceptibility of Sugar Pine and Western White Pine to Blister Rust

Key Points

Sugar pine and western white pine exhibit high susceptibility to blister rust, necessitating urgent action.
The study reveals that sugar pine is likely more susceptible than western white pine, indicating higher risk.
Control measures are required to protect sugar pine forests, where blister rust is expected to spread.
Understanding susceptibility aids in effective management against blister rust in western forests.

Abstract

Abstract Effective planning of the control of the white pine blister rust in the sugar pine and western white pine forests of the West requires a knowledge of the susceptibility of these valuable tree species to the disease. The disease is already present in the western white pine forests and it is inevitable that it will soon appear in the sugar pine forests farther south. The authors' tentative conclusion that sugar pine is fully as susceptible as the western white pine and is probably much more so, indicates that the protection of the sugar pine will require drastic control measures to make it effective.
