Weed management for giant reed (Arindo donax) biomass production in Oregon

Creator:: Attarian, Amir
Abstract:: Giant reed (Arundo donax L.) is a candidate to provide feedstock for the Portland General Electric power plant in Boardman, Oregon. Giant reed is a fast perennial grass, producing 23-27 metric tons ha⁻¹ of biomass and has the ability to adapt to diverse environments making it a good candidate for...

Seed depth influence on position of the growing point and chemical control of wild proso Millet (Panicum miliaceum L.)

Creator:: Fernandez Mendez, Raquel J.
Abstract:: Wild proso millet (Panicum miliaceum L.) is a serious weed recently infesting sweet corn fields in the Willamette Valley of western Oregon. Field and greenhouse experiments were conducted to determine the importance of seed depth in the position of the growing point of wild proso millet seedlings and in the...

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...

Seedling recruitment of hairy nightshade and other summer annual weeds in irrigated row crops

Creator:: Peachey, Ronald Edward
Abstract:: This study evaluated the effects of tillage system, rotational tillage sequences, and winter seed burial depth on weed seedling recruitment in irrigated cropping systems. Notill (NT) planting of vegetable crops reduced emergence of hairy nightshade by 77 to 99% and Powell amaranth emergence from 50 to 87% compared to conventional...

Small broomrape (Orobanche minor) biology and management in red clover (Trifolium pratense) seed production

Creator:: Lins, Ryan D.
Abstract:: Small broomrape (Orobanche minor) is a parasitic weed that attaches to the roots of red clover (Trifolium pratense). Small broomrape invasion presents a significant threat to the future of red clover seed production in Oregon. This study was conducted to investigate and develop small broomrape management options for red clover...
Resource Type:: Dissertation
Full Text:: small broomrape seeds. Future research is needed to develop control options that will prevent red

Multiple-resistant Italian ryegrass (Lolium perenne spp. multiflorum) populations in Oregon

Creator:: Liu, Mingyang
Abstract:: Italian ryegrass (Lolium perenne spp. multiflorum) is a common weed management problem in turfgrasses, cereals and non-crop areas in the United States. In Oregon, the number of populations with multiple-resistance continues to increase. To manage these resistant populations, the resistance patterns must be determined. In this study, five Italian ryegrass...

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...

Response of wheat (Triticum aestivum L.) cultivars and downy brome (Bromus tectorum L.) to metribuzin and ethyl metribuzin

Creator:: Munir, Muhammad
Abstract:: Downy brome (Bromus tectorum. L.), a serious grass weed in eastern Oregon can be partially controlled in wheat by metribuzin [4-amino-6-tertbutyl- 3-(methylthio)-as triazin -5(4H)-one]. However, cultivars of many crops Lave been reported to differ in their level of tolerance to metribuzin. This lack of tolerance has led to the investigation...
