Evaluation of natural and synthetic preemergence herbicides used in ornamental landscapes

Creator:: Hilgert, Christopher
Abstract:: A series of field experiments conducted at the Lewis-Brown horticulture farm at Oregon State University evaluated the performance of four preemergence herbicides in simulated ornamental shrub beds. Two natural products, corn gluten meal (CGM) and meadowfoam seedmeal (MFS), were used along with two synthetic products, prodiamine purchased under the trade...

New international students' perceptions of U.S. professors

Creator:: Barclay, Heather E.
Abstract:: The purpose of this study was to determine new international students' perceptions of United States professors upon entrance into the university and after two months in class, and if differences in expectations exist between groups of students based on demographic variables. A survey designed to assess these expectations was administered...

Integration of conservation tilage and cover crops in broccoli production systems of the Pacific Northwest

Creator:: O'Brien, Timothy John
Abstract:: Field and greenhouse experiments were conducted in 1996 and 1997 to evaluate the effects of integrating conservation tillage and cover cropping on broccoli production as well as agroecological parameters. A field experiment was conducted during 1996-97 at the Oregon State University Horticulture Research farm near Corvallis, OR. The specific objectives...

Environmental constraints on the use of anion exchange membranes in dryland wheat

Creator:: Redman, Andrea Elizabeth
Abstract:: Lack of growing season precipitation and the temperate climate in north central Oregon pose challenges to growing spring wheat crops. Phosphate and sulfate fertilization can improve early growth of spring wheat in this region and soil testing aids in determining rates of fertilization. In this study, anion exchange membranes (AEM)...

Structuring habitat to conserve ground beetles (Coleoptera: Carabidae) and reduce summer annual weeds in agroecosystems

Creator:: Green, Jessica M.
Abstract:: Weed management in sustainable farming systems often requires the integration of several different pest management techniques. Cultural, biological, and chemical pest control efforts can be utilized to contribute to the common goal of reducing weeds in vegetable row crop systems. This research addresses how common disturbances such as tillage and...

Solarization in the Pacific Northwest: A Mathematical Field Model for Accumulation of Linearized Mortality from Variable Intermittent Heat

Creator:: Hill, Brian C.
Abstract:: Soil solarization trials were conducted during the growing seasons of 2016-2018 with the purpose of determining if solarization was an effective pre-planting soil disinfestation technique for tree nurseries in the Pacific Northwest. A large data set was collected on soil properties and biological indicators from 5 interdisciplinary experiments. This thesis...

Improving Best Management Practices for Potato Production in the Columbia Basin : An Evaluation of Essential Oils for Control of Verticillium Wilt and the Fate of Chloride in the System

Creator:: Light, Sarah Elizabeth
Abstract:: Although the potato (Solanum tuberosum L.) is a global crop, few growing regions rival the high yields of the Columbia Basin of Eastern Oregon and Washington. Two research projects were conducted in Hermiston, OR to contribute to best management practices for the region. The first project evaluated the efficacy of...

Hybridization between yellow starthistle (Centaurea solstitialis) and meadow knapweed (Centaurea x moncktonii)

Creator:: Miskella, John
Abstract:: Centaurea solstitialis L. (yellow starthistle) and C. × moncktonii Britt. (meadow knapweed) are members of the genus Centaurea in the Asteraceae family. Both species have become serious management concerns as invasive species in North America, often displacing native vegetation and costing land managers millions of dollars to eradicate. Seven plants...

Control of Lepidium latifolium and restoration of native grasses

Creator:: Laws, Margaret S.
Abstract:: Lepidium latifolium L. (perennial pepperweed, LEPLA) is an exotic invader throughout western North America. At Malheur National Wildlife Refuge (MNWR) in southeast Oregon, it has invaded about 10% of meadow habitats that are important for wildlife. This study's objective was to determine the most effective and least environmentally harmful treatment...

Shrub epiphyte communities in relation to stand management in forests of western Oregon

Creator:: Rosso, Abbey L.
Abstract:: This dissertation describes the epiphyte communities on tall shrubs in forests of western Oregon, with a focus on potential effects of management practices on these communities. Shrubs and other hardwoods have recently gained recognition as hotspots of diversity for epiphytes in young conifer forests of the region. Yet little is...
