Publisher's Synopsis
Excerpt from Limb Rust Damage to Pine
Limb rust is a pine -killing disease in the western United States and southward to Guatemala. It was first recognized as a serious problem in 1913, when Hedgcock reported it to be the most destructive rust of western pines. In View of the later discovery of white pine blister rust in the West, Hedgcock's statement cannot now stand. However, limb rust remains the most destructive rust attacking ponderosa and Jeffrey pines throughout most of their geographic distributions. These pine Species are extremely important for timber, watershed, and aesthetic values.
Mielke in 1952 reviewed and greatly extended our knowledge of limb rust of ponderosa pine The present paper is a further review and extension of knowledge, presenting additional host, geographic, and biological data based on several years' observations. Included, too, are results from a sampling in 1965 of limb rust in Bryce Canyon National Park, and comparisons with data taken in 1935 from the same transect.
