Current research articles from the Potato Research Group are located on our publications page. Devastation caused by this plant pathogen in the late 1840s in Europe led to food shortages throughout Europe and gave rise to the Irish potato famine. Research & Extension Informationīrief descriptions of our field and postharvest research capabilities, as well as a photo gallery of our vast array of research equipment are listed here. Potato late blight caused by the oomycete Phytophthora infestans (Mont.) de Bary may be the best known, longest studied and still among the most destructive of all plant diseases. Plant Disease Clinic Cordley Hall, Room 1089, Oregon State University, Corvallis. 09-1983 COOPERATIVE EXTENSION NEW YORK STATE CORNELL UNIVERSITY A.E. We evaluate the storability and processing qualities of clones produced in early and late season management trials from Washington, Oregon, and Idaho at the postharvest storage and laboratory facilities in Pullman. Host crops: Numerous plant species including many vegetables such as bean, beet, carrot, eggplant, coriander, pepper, potato, tomato, and various cucurbits such as squash, cucumber, pumpkin, watermelon, etc. Potato DiseasesDepartment of Plant PathologyWashington State UniversityP.O. A Washington Toxics Coalition Fact Sheet. The postharvest program identifies new potato clones that have superior postharvest and culinary attributes for the Pacific Northwest potato industry. Results of annual professional evaluations of commercial potato seed lots are available online via this link as well as at the annual WSU Potato Field Day each June. Commercial Seed Lot EvaluationsĪs a service to Washington potato growers, the Potato Research Group undertakes annual Commercial Seed Lot Evaluations in order to ensure a high-quality, disease-free industry. Cultivars are ranked according to their overall performance which takes into account economics, yields, tuber-size profiles, tuber quality and many postharvest attributes. An economic analysis is conducted on all clones and cultivars for both the fresh and process markets, with the exception of the red and specialty clones. This publication is available as a printed volume (the Potato Cultivar Yield and Postharvest Quality Evaluations yearbook) as well as an electronic publication. Information we provide Tri-State and Regional Variety TrialsĮach year, we publish variety-trial results in user-friendly graphs, figures, and charts. For the current status of late blight in the Columbia Basin and management recommendations, call the late blight hotline: 1-80 (Washington) or 1-80 (Oregon). Our goal is to provide relevant and up-to-date information that can be used by growers, processors, fresh-pack sheds, researchers, and other industry personnel. The late blight organism, Phytophthora infestans, will most likely find and infect any plants or plant surfaces skipped during application. You can learn more about our mission here. Our mission is to identify new potato varieties and cultural and postharvest management practices that will provide profitable production for the grower, improved competitiveness for the Washington potato industry, a healthy, inexpensive food supply for American consumers, and a sustainable environment.
