  • Integrated small broomrape (Orobanche minor Sm.) management in red clover (Trifolium pratense L.)

    Creator:
    Ross, Kyle C.
    Abstract:
    Small broomrape, a holoparasitic weed, is a relatively new weed introduction in the Pacific Northwest that has contaminated a limited number of red clover fields in Oregon. Greenhouse and field studies were conducted to evaluate small broomrape response to common crop and weed species in the Pacific Northwest. Host species...

  • Weed control with glyphosate and glufosinate in herbicide-resistant sugarbeets (Beta vulgaris L.).

    Creator:
    Guza, Corey J.
    Abstract:
    Field studies were conducted in 1998 and 1999, to evaluate glyphosate and glufosinate for control of redroot pigweed, common lambsquarters, hairy nightshade, and barnyardgrass in herbicide-resistant sugarbeets. Treatments that included two or three applications of glyphosate, regardless of rate, or glyphosate applied once in combination with BAS 656 07 H...

  • Factors influencing storage quality of hazelnut varieties

    Creator:
    Ebrahem, Kais Shaheb
    Abstract:
    This thesis research is a series of five studies dealing with various aspects of hazelnut quality: 1. Identification of kernel mold and its incidence among hazelnut varieties. 2. Seasonal development and composition of kernels. 3. Hazelnut oil composition (fatty acids and tocopherols) of seventeen varieties. 4. Hazelnut oil composition compared...

  • Clonal variation in Russet Norkotah and Umatilla Russet potato varieties

    Creator:
    Brunick, Robert L.
    Abstract:
    These studies compared giant hill strains of Russet Norkotah and Umatilla Russet to the parent varieties. Selections were initially based on late maturity and increased vine vigor. Subsequent evaluations emphasized yield and quality parameters in comparison to the parent varieties. Giant hills were collected from the Columbia Basin and Central...

  • Winter cover cropping effects on integrative biological indicators of soil quality

    Creator:
    Ndiaye, Evelyne L.
    Abstract:
    Responses of biological indicators of soil quality to winter cover cropping were measured on soil samples collected from 6 commercial growers' fields and two experiment research stations in the Willamette Valley of Oregon. The research stations were the North Willamette Research and Extension Center (Aurora, OR), and the Oregon State...

  • Nursery container weeds response to modification of substrate pH, substrate particle size and applied nitrogen form

    Creator:
    Wada, Sugae
    Abstract:
    Experiments were conducted to determine the influence of cultural management practices on weed growth in nursery containers. Experiments 1 and 2 evaluated the effects of dolomitic lime rate and application method on substrate pH, creeping woodsorrel (Oxalis corniculata L.) establishment in containers, and growth of azalea (Rhododendron ‘Rosebud’) and pieris...

  • Molecular basis of target-site resistance to acetolactate synthase-inhibiting herbicides in mayweed chamomile (Anthemis cotula L.)

    Creator:
    Intanon, Suphannika
    Abstract:
    Mayweed chamomile (Anthemis cotula L.) is an annual weed in the Asteraceae family that is commonly found in fields of the Pacific Northwest. Acetolactate synthase (ALS)-inhibiting herbicides are frequently used to control a broad spectrum of weed species including mayweed chamomile. Seeds of four biotypes of mayweed chamomile (KJ, KL1,...

  • Non-herbicidal effects of dinoseb on winter wheat yields

    Creator:
    Valverde, Bernal E.
    Abstract:
    A series of experiments were conducted from 1983 to 1985 to determine the effects of dinoseb [2-(1-methylpropyl)-4,6-dinitrophenol] on winter wheat (Triticum aestivum L. em Thell) yields. Field trials on dinoseb timing and dinoseb plus supplemental pesticides were established in an effort to elucidate the possible factors involved in the yield...

  • Interaction of ethofumesate with dry soil

    Creator:
    McAuliffe, David
    Abstract:
    Previous studies have shown loss of ethofumesate activity when the herbicide was applied to dry soil (2% w/w moisture content) in both field and greenhouse studies, even when rainfall or irrigation was received within a few days. Laboratory studies were conducted to determine the mechanism for this activity loss. Dry...

  • Physiological responses of creeping red fescue to stubble management and plant growth regulators

    Creator:
    Meints, Paul David
    Abstract:
    Legislation to reduce open field burning in grass seed fields within the Willamette valley of western Oregon changed established production practices. In the creeping grasses such as Kentucky bluegrass (Poa pratensis L.) and creeping red fescue (Festuca rubra L.) non-thermal management resulted in reduced yield. Studies were conducted to examine...
