Simulation of population changes of western dwarf mistletoe on Ponderosa pine

Creator:: Strand, Mary Ann Sall, 1945-
Abstract:: Western dwarf mistletoe (Arceuthobium campylopodum Engelm. 1. campylopodum) is a parasite of ponderosa pine (Pinus ponderosa Laws. ). The objectives of this investigation are: (a) to formulate a mathematical description of the process of dwarf mistletoe disease spread in a pine forest, (b) to use this description to predict the...

The life history of Anisogramma anomala (Pk.) E. Müller (Diaporthaceae) and its pathological and epidemiological association with Corylus avellana L.

Creator:: Gottwald, Timothy Ross
Abstract:: Eastern Filbert Blight, caused by Anisogramma anomala (Peck) E. Miller, was first discovered in the Pacific Northwest in 1974. Orchard experiments suggest that the fungus completes its life cycle in two years. Infection takes place from mid-January to May, mainly through mite-galled-buds infested with an Eriophyid mite, Phytocoptella avellanae Nal....

Epidemiology of Lophodermella morbida in plantations of ponderosa pine in western Oregon

Creator:: Harvey, George M.
Abstract:: In 1967, Lophodermella morbida Staley and Bynum, a recently described hypodermataceous needle-cast fungus, became destructively epidemic in a knobcone pine (Pinus attenuata Lemm.) plantation in Del Norte County, California, and in several ponderosa pine (P. ponderosa Laws.) plantations in western and southwestern Oregon. This thesis presents information on this currently...

Interactions between paired cultures as a basis for differentiating compatibility genotypes of Fomes cajanderi Karst. from glaze-damaged Douglas-fir

Creator:: Adams, David Howard
Abstract:: A study was undertaken to determine the reliability of the formation of a line of demarcation between paired cultures of Fomes cajanderi Karst. as an indicator of dissimilar compatibility genotypes. The results were applied to an assay of the number and location of compatibility genotypes in each of four glaze-damaged,...
