The Use and Role of Predictive Systems in Disease Management

Creator:: Gent, David H., Mahaffee, Walter F., McRoberts, Neil, and Pfender, William F.
Abstract:: Disease predictive systems are intended to be management aids. With a few exceptions, these systems typically do not have direct sustained use by growers. Rather, their impact is mostly pedagogic and indirect, improving recommendations from farm advisers and shaping management concepts. The degree to which a system is consulted depends...

The Biology and control of the septoria diseases of winter wheat in western Oregon

Creator:: DiLeone, Julie A., Coakley, Stella M., Karow, Russ, Mundt, Christopher C., and Oregon State University. Agricultural Experiment Station
Abstract:: The septoria diseases of winter wheat are a limiting factor to wheat production in the Willamette Valley. This publication will describe the symptoms and development of the septoria diseases, including the influence of environmental conditions, the reactions of different cultivars to Septoria, the impact of Septoria on yield, and control...

Final Report: Controlling Tall Oatgrass in Fender’s Blue Butterfly Habitats

Creator:: Wilson, Mark V. and Clark, Deborah Louise, 1950-
Abstract:: We report final results from a five-year field experiment evaluating the effects of different mowing regimes on groups of native and non-native grasses and forbs. The study site was a degraded prairie at Baskett Slough National Wildlife Refuge dominated by the pest plant Arrhenatherum elatius (tall oatgrass). Mowing treatments differed...

Fire effects on wetland prairie species : final report

Creator:: Clark, Deborah L., Wilson, Mark V., and Clark, Deborah Louise, 1950-
Abstract:: Wetland prairies of the Willamette Valley, considered among the rarest of Oregon’s ecosystems, are threatened by invasion of woody species and non-native species. Because of its historical importance, fire is a top choice of managers for preventing the encroachment of woody species. However, the effects of prescribed burning on present...

Final Report for the project: Research on Habitat Manipulation and Management of Fender's Blue Butterfly Areas

Creator:: Wilson, Mark V. and Clark, Deborah Louise, 1950-
Abstract:: We report first-year results from two field experiments evaluating the effectiveness of various techniques for the control of pest plants in Fender's blue butterfly habitat. In the woody-plant study, we monitored the effects of mowing, mowing and herbicides, and burning on woody plants and key native and non-native grasses and...

Annual cycles of ecological disturbance and recovery underlying the subarctic Atlantic spring plankton bloom

Creator:: Behrenfeld, Michael J., Doney, Scott C., Lima, Ivan, Boss, Emmanuel S., and Siegel, David A.
Abstract:: Satellite measurements allow global assessments of phytoplankton concentrations and, from observed temporal changes in biomass, direct access to net biomass accumulation rates (r). For the subarctic Atlantic basin, analysis of annual cycles in r reveals that initiation of the annual blooming phase does not occur in spring after stratification surpasses...

Final report, year two: Control of Brachypodium sylvaticum and restoration of rare native upland prairie habitat at Butterfly Meadows, Benton County ODA 1514 GR

Creator:: Clark, Deborah Louise, 1950-, Blakeley-Smith, Matt, Hammond, Paul, Johnson, Deborah, Kaye, Tom, Kelpsas, Bruce, Pfund, Fred, Vomocil, Marc, and Wilson, Mark V.
Abstract:: Our project goal is to protect and restore rare Willamette Valley upland prairie habitat at Butterfly Meadows (Benton County) from invasion by the noxious weed Brachypodium sylvaticum (false brome). Native prairies, which once dominated the landscape of the Willamette Valley, are considered among the rarest of Oregon’s ecosystems and are...

Abstract:: We report results from a field experiment evaluating the effectiveness of mowing, mowing and herbicides, and burning on woody plants, key native and non-native grasses and forbs, and the Fender's blue butterfly. The goal was to find a technique that controlled woody pest plants without harming native species or promoting...
