Soil Solarization for Weed Management in Tree Seedling Nurseries in the Pacific Northwest

Creator:: Wada, Nami
Abstract:: Soil solarization is a pre-planting practice to reduce weed pressure by trapping solar energy using a transparent polyethylene film to heat soil. Soil solarization has been successfully used in regions with high solar radiation. The purpose of this research was to determine if soil solarization under Pacific Northwest conditions could...

Seed Development in Orchardgrass (Dactylis glomerata L.) in Relation to Plant Growth Regulators and Spring Nitrogen

Creator:: Morad, Mohammed M.
Abstract:: Orchardgrass (Dactylis glomerata L.) is an important seed crop, but unlike other cool-season perennial grass seed crops such as perennial ryegrass (Lolium perenne L.) and tall fescue [Schedonorus arundinaceus (Schreb.) Dumort.], seed yields have not increased over time so there is considerable room for improvement. Research suggests that plant growth...

Evaluation of Fusarium proliferatum Mycotoxin Profiles in Infected Garlic Cloves

Creator:: Rossi, Francesca
Abstract:: Fusarium proliferatum is a fungus found in soils which produces the mycotoxin group known as fumonisins. Of human concern due to hepato-, nephro- and neurotoxicity, the threat of fumonisins lies within several food items, including corn, wheat sorghum, asparagus and, more recently, garlic. Manifesting as ““garlic rot”,” F. proliferatum infection...

Response of Roughstalk Bluegrass (Poa trivialis L.) to Waterlogging Stress

Creator:: Liu, Mingyang
Abstract:: Roughstalk bluegrass (Poa trivialis L.) (RB) is a weed species that increased very quickly in grass seed production fields of the Willamette Valley. The invasion of RB in grass seed crops often occurs in waterlogged soils. In waterlogged areas, RB exhibited better competitiveness and had greater population densities than other...

Diseases of Rhododendron and Boxwood: Survey and Virulence of Phytophthora Root Rot and Management of Boxwood Blight with Systemic Fungicides

Creator:: Sacher, Gabriel
Abstract:: Diseases can be a substantial threat to woody plant production, a major industry in Oregon. Boxwood (Buxus spp.) and rhododendron (Rhododendron subgenus Rhododendron and Hymenanthes) represent the top two broadleaf evergreen woody plants by farmgate value in Oregon. Historically, Phytophthora root rot has been considered the most destructive disease of...

Water management tools and irrigation strategies for blueberry, blackberry, and raspberry production in the Pacific Northwest

Creator:: Carroll, Jesse L.
Abstract:: The Pacific Northwest region of the United States is known for quality production of blueberries, blackberries, and red raspberries. However, as the climate shifts to warmer, drier, and more extreme summers, growing these water intensive berry crops is becoming increasingly difficult. Furthermore, water regulations within agriculture are becoming more prevalent...

Genome Resource Development for Advancement of Corylus avellana Breeding

Creator:: Talbot, Samuel Corcoran
Abstract:: The European hazelnut (Corylus avellana L.) is a tree nut crop that is important in Oregon, which produces 99% of the United States’ hazelnuts but only 5% of the world’s supply. In order to maintain this market share, farmers in Oregon need cultivars that produce high quality nuts, mature early,...

Evaluation of Methods for Applying Phosphorus, Potassium, and Boron Fertilizers in Northern Highbush Blueberry (Vaccinium corymbosum L.)

Creator:: Leon-Chang, David P.
Abstract:: Previous studies indicated that fertigating with nitrogen (N) was more effective than using granular N fertilizers in production of northern highbush blueberry (Vaccinium corymbosum L.). To build on these findings, four studies were conducted in western Oregon to determine whether fertigation was also an effective method for applying other nutrients,...

Characterization of microaggregate formation by Mycobacterium avium subspecies hominissuis

Creator:: Babrak, Lmar
Abstract:: Mycobacterium avium subsp hominissuis (MAH) is an opportunistic environmental pathogen that causes respiratory and gastrointestinal illness in immunocompromised persons such as those with chronic respiratory diseases or AIDs, respectively. In recent years, there has been a significant increase in the incidence of nontuberculous mycobacterial (NTM) lung infections, including in cystic...
