Small broomrape (Orobanche minor) management using wheat (Triticum aestivum) as a false host

Creator:: Al-thahabi, Salam A.
Abstract:: Small broomrape (Orobanche minor) is an obligate, chlorophyll-lacking parasite that parasitizes red clover (Trifolium pratense) roots. This study was conducted to develop and implement an integrated, biologically based control program for small broomrape by using wheat as a false host to reduce the soil seed bank. The relationship between temperature...

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...

Decomposition of Brassicaceae Residue in the Willamette Valley

Creator:: Berry, Pete A.
Abstract:: An important inoculum source of Leptosphaeria maculans and L. biglobosa (syn Plenodomus spp.), the pathogens that cause black leg in Brassicaceae crops, is infected plant residues. The general acceptance of conservation tillage in the Willamette Valley, Oregon, USA, has enabled a build-up in the amount of residue on or near...

Jointed goatgrass (Aegilops cylindrica Host) genetic diversity and hybridization with wheat (Triticum aestivum L.)

Creator:: Gandhi, Harish Tulshiramji
Abstract:: Jointed goatgrass (Aegilops cylindrica Host; 2n=4x=28; CCDD) is an agriculturally important species both as a weed and as a genetic resource for wheat (Triticum aestivum L.; 2n=6x=42; AABBDD) improvement. In order to better understand the evolution of this species, the diversity of Ae. cylindrica was evaluated along with its progenitors,...

ALS-inhibitor resistant downy brome (Bromus tectorum L.) biotypes in Oregon : Mechanism of resistance, fitness, and competition

Creator:: Park, Kee-Woong
Abstract:: Understanding the mechanism of resistance, relative fitness and competitiveness of herbicide resistant biotypes is important to predict population dynamics and to establish resistance management strategies. This study was conducted to determine the level of resistance to acetolactate synthase (ALS) inhibitors and the mechanism of resistance of ALS-inhibitor resistant downy brome...

Glyphosate Resistance and Tolerance in Italian Ryegrass (Lolium perenne spp multiflorum) : Termination Treatments, Cultivar, and Resistance Evaluation

Creator:: MacPherran, Robert Chase
Abstract:: Annual ryegrass, or Italian ryegrass (Lolium perenne spp. multiflorum), has been the most stable, in terms of acres, grass produced for the past 25 years in Oregon. Increased interest in Italian ryegrass as a cover crop has increased demand for quality seed. Ideal Italian ryegrass cover crop cultivars are named...

Perennial Ryegrass (Lolium perenne L.) Cultivar Response to a Postemergence Application of Mesotrione

Creator:: Hinds-Cook, Barbara J.
Abstract:: Perennial ryegrass (Lolium perenne L.) is a widely grown cool season, bunch type, short lived perennial grass that is native to Europe, Asia, and North Africa, but has been adapted globally. Perennial ryegrass is quick to establish, has a long growing season, and produces high seed yield and forage or...

Brassicaceae Seed Persistence and Dormancy in the Willamette Valley

Creator:: Flick, Gabriel D.
Abstract:: Producers in the Willamette Valley of Oregon are interested in growing canola as a rotational crop in grass seed and cereal rotations. Many other Brassicaceae seed crops also are produced within the valley. Concerns of seed persistence and volunteer contamination of Brassicaceae seed crops prompted the investigation of seed persistence...

Gene flow from transgenic glyphosate-resistant creeping bentgrass (Agrostis stolonifera L.) at the landscape level

Creator:: Zapiola, Maria Luz
Abstract:: Creeping bentgrass (Agrostis stolonifera L.) is an outcrossing, small- seeded, perennial grass that can establish outside of cultivation and has several compatible relatives. Glyphosate is a nonselective, broad spectrum, herbicide. Transgenic glyphosate-resistant (GR) creeping bentgrass (GRCB) was developed by The Scotts Company and Monsanto, but is still under USDA-APHIS regulated...
