On-farm inquiry and assessment of tillage and cover cropping for white mold control in snap bean production

Creator:: Harrison, Elizabeth Langham.
Abstract:: Cultural practices in snap bean production were evaluated at the Oregon State University Vegetable Research Farm Corvallis, Oregon. In addition, decision-making in snap bean production was assessed on five farms in the Coburg-Junction City-Harrisburg regions of the Willamette Valley, Oregon. A field experiment with cover crop and tillage techniques was...

Detection, identification, and antibiotic treatments of bacterial contaminants from micropropagated strawberries

Creator:: Tanprasert, Piyarak
Abstract:: Bacterial contamination is one of the most important problems both in plant tissue culture research and commercial laboratories. Early detection of contaminants saves time, effort, and money. Strawberry runner explants were screened for contaminants during June to August, 1994 and 1995. Most contaminants found were bacterial rather than fungal. Bacterial...

Phenology, Host-Plant Resistance, and Biological Control of Stephanitis pyrioides in Oregon

Creator:: Flores, Salvador M.
Abstract:: The azalea lace bug (Stephanitis pyrioides Scott) is a recently detected invasive pest to the Pacific Northwest and has become a major concern in Oregon. It feeds on azaleas as well as rhododendrons causing stippling on the top side of leaves. The damage is aesthetically displeasing and affects plant vigor...

Microsatellite Marker Development, Characterization and Mapping in European Hazelnut (Corylus avellana L.), and Investigation of Novel Sources of Eastern Filbert Blight Resistance in Corylus

Creator:: Bhattarai, Gehendra
Abstract:: European hazelnut, an important nut crop in Oregon agriculture, is threatened by the fungal disease eastern filbert blight (EFB) caused by Anisogramma anomala (Peck) E. Müller. The hazelnut breeding program at OSU has been working on development of EFB-resistant cultivars. DNA markers allow mapping of traits using segregating progenies and...

Multiple pest suppression with cover crops in strawberry

Creator:: Datta, Braja Bandhu
Abstract:: The experiment was conducted to compare multiple pest (weed, soil arthropod and diseases) suppression by cereal cover crops in 'Selva' and 'Totem' strawberry. In addition, perlite was used to compare improvement of soil and root aeration which might modify strawberry black root rot complex. Small-seeded summer annual weeds were suppressed...

Managing Microdochium Patch Using Non-Traditional Fungicides on Annual Bluegrass Putting Greens

Creator:: Mattox, Clint M.
Abstract:: Currently, fungicide applications are the predominant method of control for the cool weather pathogen Microdochium patch (Microdochium nivale). Increasing pesticide restrictions have generated concern regarding management of Microdochium patch. Three separate field trials exploring non-traditional fungicides were conducted between 2013 and 2015 on an annual bluegrass (Poa annua L.) sand-based...

Investigation of novel sources of genetic resistance to eastern filbert blight

Creator:: Lunde, China F.
Abstract:: To identify novel host genetic resistance to eastern filbert blight, caused by the fungus Anisogramma anomala (Peck) E. Muller, ninety European hazelnut {Corylus avellana L.) varieties and interspecific hybrids (with C. americana Marsh, or C. colurna L.) were screened for response to the eastern filbert blight pathogen after inoculation in...

Effect of row cover and supplemental Ca fertilization on blossom-end rot in bell pepper (Capsicum annuum var. annuum, Grossom Group)

Creator:: Alexander, Shara E.
Abstract:: A 2-year trial was conducted at Oregon State University's Hermiston Agricultural Research and Extension Center to examine the effects of spunbonded row cover and supplemental calcium fertilization on blossom-end rot in two varieties of bell pepper. Blossom-end rot is a common cause of bell pepper yield losses, especially at the...

Pyramiding quantitative trait loci conditioning partial resistance to Sclerotinia sclerotiorum in bush blue lake green beans (Phaseolus vulgaris)

Creator:: Barrett, Miles Andrew
Abstract:: Sclerotinia sclerotiorum (Lib.) de Bary is a necrotrophic pathogen capable of causing white mold, a severe disease in common bean. White mold is of particular concern to the Oregon snap bean processing industry, where processors allow less than 3% incidence in harvested shipments. Breeding for white mold resistance in beans...

Disease resistance and spring phenological characteristics of Ribes L. germplasm

Creator:: Dalton, Daniel T.
Abstract:: North American cultivation of Ribes L. may expand as small fruit growers seek species to diversify horticultural crops. The Ribes industry was suppressed for decades out of fear that cultivated black currants and gooseberries would intensify the fungal disease white pine blister rust (WPBR) on five-needle pine (Pinus L. section...
