Influence of site, soil, and inoculum density on dwarf bunt (Tilletia controversa Kühn) of winter wheat

Creator:: Clark, Deborah Ann, 1954-
Abstract:: Field microplot studies conducted over two seasons (1982-1984) evaluated the influence of four physically and chemically diverse soils collected from Pacific Northwest wheat fields on the incidence of dwarf bunt of winter wheat caused by Tilletia controversa Kuhn. These soils were placed at Flora and Pendleton, Oregon to determine the...

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...

Role of inoculum sources of Botrytis cinerea in the epidemiology of gray mold of snap beans

Creator:: Johnson, Kenneth Bjorn
Abstract:: Spore dispersal gradients and pod disease gradients from point inoculum sources of Botrytis cinerea were measured over time in two snap bean field experiments. Laboratory grown inoculum was placed at ground level in a 30 x 30 cm square at bloom initiation and removed at full bloom. Dispersal of inoculum,...

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...

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,...

Sweet corn decline syndrome in Oregon's Willamette Valley

Creator:: Hoinacki, Elisabeth V.
Abstract:: For the past several years vegetable growers in Oregon's Willamette Valley have experienced reduced yields in their sweet corn plantings. We conducted studies to 1) describe the symptomology and etiology of the disease, 2) test a root rot rating system we developed to evaluate factors in the disease syndrome, and...

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...
