Abstract

Results of a coordinated soil-rootlet mortality study in 1954 indicate that the severity of the pole blight disease of western white pine (Pinus monticola Dougl.) is significantly correlated with certain physical soil characteristics and rootlet mortality. The finding of this relationship does not necessarily imply that these factors are the cause of pole blight. Evidence reported herein was obtained from a detailed study of 6 healthy and 11 diseased 1-acre plots, well distributed throughout the white pine type of northern Idaho. This study is being continued.
