  • 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...

  • Cereal residue effects on weeds and cucumbers

    Creator:
    Peachey, Ronald Edward
    Abstract:
    Cereal residues suppress the development of small seeded, summer annual weeds. The focus of this study was to determine whether cereal residues can be used to suppress weeds in cucumber production systems in the Pacific Northwest. In the first of three experiments, cereal residues of fall-planted, spring-killed cover crops suppressed...

  • 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...

  • 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...
