Water deficit stress effects on bacterial ring rot of potato caused by Clavibacter michiganensis subsp. sepedonicus

Creator:: Crabtree, Kristine L.
Abstract:: Population size of Clavibacter michiganensis subsp. sepedonicus in potato cv Russet Burbank and plant response as affected by drought were assessed in a greenhouse experiment. Water deficit stress and no stress treatments, and inoculum densities of 0 or 2 X 10⁷ cfu C. m. sepedonicus/seed piece were arranged factorially. Stem...

A potato growth and production model

Creator:: Apple, Jeanne Debons
Abstract:: A potato plant growth and production model is developed with the objectives of analyzing management alternatives and exploring the nature of the early dying syndrome. The geographic area of focus was the centerpivot irrigated circles of Oregon's Columbia Basin. A problem analysis of the potato production system of this area,...

Irrigation water and plant density effects on the epidemiology of aerial stem rot of potatoes

Creator:: Cappaert, Marlys R.
Abstract:: Field plots of cv. Russet Burbank potatoes from a single seedlot were established at four sites over two seasons (1985-86) in two locations in Oregon to determine the role of water-borne inoculum of Erwinia carotovora in plant infection. One site at each location was irrigated from a surface-water source and...

Soil water pressure and Verticillium dahliae interactions on potato

Creator:: Gaudreault, Suzanne M.
Abstract:: A greenhouse experiment was conducted in 1991 and in 1992 to determine the effect of soil water pressure on potato (cv Russet Burbank) plant growth and infection by Verticillium dahliae. Soil water pressures of -0.01, -0.03, -0.08, or -0.15 MPa were combined factorially with two inoculum concentrations, 0 or 10...

Seedborne Phytophthora infestans : effect of pathogen clonal lineage and potato cultivar on seed transmission of late blight and plant growth responses

Creator:: Partipilo, Heather M.
Abstract:: Seed piece to plant transmission of the potato late blight pathogen, Phytophthora infestans, occurred with isolates of the clonal lineages US-8 in Oregon and US-11 in Washington in field trials. Average transmission rate across potato cultivars was 0.5 and 2.4% with US-8, and 0.8 and 1.0% with US-11 in 1999...

Effect of a broccoli green manure, soil solarization, and isolates of Verticillium dahliae on Verticillium wilt of agronomic and nursery crops

Creator:: Berlanger, Ingrid E.
Abstract:: Green manures, soil solarization, and long rotations with crops not susceptible to Verticillium wilt are among the disease management tactics currently under investigation as alternatives to chemical fumigation of soil. The effect of a broccoli green manure on soil microsclerotial populations of three isolates of Verticillium dahliae and on Verticillium...

Influence of a sudangrass green manure on microorganisms and early dying of potatoes in two soils

Creator:: Parks, Robin L.
Abstract:: Effect of a sudangrass green manure in two soil types on the activity, populations and community structure of soil microorganisms, populations of Verticillium dahliae in soil and on potato roots, and potato early dying, were evaluated in a field microplot experiment in the Columbia Basin. Potato cv. Russet Burbank was...

Potential of Trichoderma sp. for inhibition of Botrytis cinerea and Sclerotinia sclerotiorum on snap beans

Creator:: Nelson, Mark E.
Abstract:: Isolates of Trichoderma spp. collected from snap bean foliage were tested for inhibition of grey mold of snap beans caused by Botrytis cinerea. In a detached blossom-pod assay an isolate of Trichoderma hamatum reduced pod rot by 94% compared to the nontreated check. Control was comparable to that obtained with...

The roles of Verticillium dahliae, Colletotrichum atramentarium, Erwinia carotovora subsp. carotovora and E. carotovora subsp. atroseptica in "early dying" disease of potatoes

Creator:: Kirkland, Marjorie Lynn
Abstract:: The primary cause of "early dying" disease of potatoes in Oregon is Verticillium dahliae; however, Colletotrichum atramentarium, Erwinia carotovora subsp. carotovora (Ecc) and E. carotovora subsp. atroseptica (Eca) are also commonly isolated from diseased plants. Therefore, field and greenhouse studies were initiated to determine the relative involvement of each pathogen,...
