Biology of sweet cherry powdery mildew

Creator:: Calabro, Jill M.
Abstract:: The Pacific Northwest has become one of the nation’s premier sweet cherry, Prunus avium, production areas. As production of sweet cherries has flourished in Oregon and Washington, so has powdery mildew, caused by the fungus Podosphaera clandestina, which infects both foliage and fruit causing severe economic damage to growers. Sweet...

How to reduce the risk of pesticide resistance in apple pests in Oregon

Creator:: Kaiser, Clive, Azarenko, A. N. (Anita Nina), Spotts, Robert Allen, 1945-, and Oregon State University. Extension Service
Abstract:: Pesticides—including insecticides, acaricides, fungicides, and bactericides are essential for maintaining healthy crops with reliable yields and quality. In many instances, pesticides have become less effective as target organisms have developed resistance. The first record of resistance dates to 1897, when orchardists began having problems controlling San Jose scale (Quadraspidiotus perniciosus...

How to identify, scout, and control insect pests in vegetable crops

Creator:: Rondon, Silvia I., Clough, George H., 1945-, Corp, Mary K., and Oregon State University. Extension Service
Abstract:: Correct identification of pest problems is the beginning of a successful integrated pest management (IPM) program. Regular scouting can provide early warning of problems, allow the widest range of control options, and bring favorable economic, ecological, and social consequences.

David, Lynn, Ronald J., Peterson, William T., and Venrick, Elizabeth
Abstract:: This report summarizes physical and biological conditions in the California Current System (CCS), from Oregon to Baja California, in 2001 and 2002. The principal sources of the observations described here are the CalCOFI (California Cooperative Oceanic Fisheries Investigations), IMECOCAL (Investigaciones Mexicanas de la Corriente de California), and U.S. GLOBECLTOP (Global...

The state of California, 2003 - 2004 : still cool?

Creator:: Goericke, Ralf, Venrick, Elizabeth, Mantyla, Arnold W., Hooff, Rian, Collins, Curtis A., Gaxiola-Castro, Gilberto, Bograd, Steven J., Schwing, Franklin B., Peterson, William T., Marinovic, Baldo, Durazo, Reginaldo, Huyer, Adriana, 1945-, Smith, Robert L. (Robert Lloyd), 1935-, Wheeler, Patricia A., Chavez, Francisco, Lo, Nancy, Hyrenbach, K. David, and Sydeman, William J.
Abstract:: This report summarizes the recent state of the California Current System (CCS), primarily during the period of April 2004 to January 2005. The report is based on observations made between Oregon and Baja California by various ocean observing programs. The CCS was not forced by any coherent basin-wide processes during...

Development of a “smart” tracer for the assessment of microbiological activity and sediment-water interaction in natural waters: The resazurin-resorufin system

Creator:: Haggerty, Roy, Argerich, Alba, and Marti, Eugenia
Abstract:: A “smart” tracer is a tracer that provides, directly or through measurement of its concentration or in combination with another compound, at least one “bit” more of information about the environment through which it travels than a conservative tracer. In this study we propose and present the chemical compound resazurin...

Supplemental feeding influences reproductive success of the Hawaiian goose (Branta sandvicensis) at Haleakala National Park, Maui, Hawai'i

Creator:: Tamayose, Joy
Abstract:: Low reproductive success has been typical of high elevation populations of the Hawaiian goose (Branta sandvicensis) or nēnē. Researchers identified predation and inadequate nutrition as limiting factors. Reproductive success remained low in most years despite on-going predator control programs. I used a supplemental feeding program over two breeding seasons in...

Potential Heterotic Groups in Hop as Determined by AFLP Analysis

Creator:: Townsend, M. Shaun and Henning, John A.
Abstract:: Hop (Humulus lupulus L.) is a perennial, dioecious species in which the female inflorescence (cones) are harvested and used in the beer-brewing process to impart bittering and/or flavoring to beer. Hop breeders have typically utilized clonal selection and hybridization to develop new cultivars. The use of genetically diverse parents for...

Hydrothermal links between ocean plateau formation and global anoxia at the Cenomanian-Turonian boundary

Creator:: Snow, Laura J.
Abstract:: The Cretaceous was a period of extreme climatic conditions accompanied by major perturbations in ocean-atmosphere biogeochemical cycles. One of the most intriguing features is the sporadic interruption of normal marine pelagic sediment deposition by organic rich sediments deposited during oxygen-deficient conditions (ocean anoxic events OAEs). A current model for the...

The Biology and ecology of weeping alkaligrass (Puccinellia distans) and Nuttall’s alkaligrass (Puccinellia nuttalliana)

Creator:: Tarasoff, Catherine
Abstract:: Weeping alkaligrass (Puccinellia distans) and Nuttall’s alkaligrass (Puccinellia nuttalliana) infest Kentucky bluegrass seed fields of eastern Oregon. Weeping alkaligrass is an introduced species from Eurasia, whereas Nuttall’s alkaligrass is native to semi arid environments of western North America. These species are often referred to collectively as ‘alkaligrass’; however, for farmers...
