Washington State University Puyallup Research and Extension Center


Avian Health and Food Safety Laboratory

Avian Health and Food Safety Laboratory (WADDL) is part of Washington State University’s College of Veterinary Medicine. The state of the art diagnostic laboratory, located at WSU Puyallup, provides diagnostic services including complete necropsy, bacteriology, mycology, virology, serology and DNA testing of all avian species. Services are also provided to back yard poultry, waterfowl, wild birds, zoo birds and rabbits.

Agricultural Economics

The primary research and outreach program goal is to enhance value-added agribusiness opportunities for specialty crops in the state of Washington. As such, areas of research are focused on consumer demand analysis and economics of technological change; specifically research assessing consumers’ preferences for foods including fresh fruit quality, understanding production and marketing dynamics impacts on the profitability of food production operations’ and adoption of new technologies—at the field and the processing level.

Center for Sustaining Agriculture and Natural Resources (CSANR)

The mission of the CSANR is to develop and foster agriculture and natural resource management approaches that are economically viable, environmentally sound, and socially acceptable. Rather than duplicate ongoing efforts, the center strives to facilitate interdisciplinary linkages and coalitions between WSU, growers, industry, environmental groups, agencies, and the people of Washington. As a university center devoted to sustainability, CSANR is uniquely positioned to leverage the resources of the land grant university and communities in our state. Some of the Center’s current activities include: Biologically Intensive Agriculture and Organic Farming (BIOAg), Climate Friendly Farming, Community Capacity Building and Conflict Resolution, Education on Farming and Food Systems, Policy Research and Education, Small Farms Program.


The mission of the Ecotoxicology Program at WSU Puyallup is to study the impacts of pesticides and other toxicants on populations, communities, and food webs with particular emphasis on aquatic organisms inhabiting rivers and streams in the Pacific Northwest, including salmon and the invertebrates that they feed upon. This is accomplished through a mix of laboratory and field studies. The laboratory studies involve developing toxicity data for animals exposed to various chemicals. The effects of low concentrations of the mixtures and concentrations of pesticides commonly found in Washington fresh water systems are also being investigated. The WSU Salmon Research Laboratory was developed to investigate the effects of multiple pesticides and other toxicants commonly found in Pacific Northwest surface waters on salmon health. The program is supported in part by cooperative agreements with the National Marine Fisheries Service and their Northwest Fisheries Science Center in Seattle. The WSU Food and Environmental Quality Laboratory in Richland, Washington is a partner in the program and provides analysis of chemical residues.

Integrated Pest Management and Pesticide Education

The WSU Urban Integrated Pest Management (IPM) and Pesticide Safety Education Program helps landscape and turf professionals manage pests and develop a successful integrated pest management program. The program provides pre-license courses and recertification workshops, including pesticide applicator and IPM training in Spanish.

Master Gardener Program

The WSU Master Gardener Program is WSU’s most famous outreach program and the only uniquely WSU program that has been adopted both nationally and internationally. Active in 36 of our 39 counties, the WSU Master Gardener Program has over 4,000 active adult Master Gardener Volunteers working on behalf of WSU Extension, providing an annual contribution of more than $3.5 million in donated time, about the same as having an additional 65 county faculty positions. WSU Master Gardener volunteers in Washington each give an average of 52 hours of volunteer service during the year, annually serving over a 250,000 people with science-based horticultural information and programs. The WSU Master Gardener Program also includes a network of 167 “Plant Clinics” operating in 105 communities that offer plant, insect, and disease diagnosis to the public. Approximately 800 persons are trained each year, with approximately 95% becoming WSU Extension volunteers.

Natural Resource Science

The Natural Resource Science Program involves the breeding and testing of hybrid poplars for growth, disease resistance, and wood chemical and physical traits as it relates to energy content and conversion efficiency to ethanol. A clone arboretum is managed for breeding purposes, and research is conducted on the production physiology of fast growing tree species including hybrid poplars, alders, willows and selected conifers. New directions in research include the breeding and testing of hybrid alder, the physiology of poplar leaf rust, and environmental uses of these tree species in riparian buffer plantings, for carbon sequestration and for wastewater reuse in the Pacific Northwest.

Nutrition Education

The Nutrition Education Program addresses important nutrition education issues for individuals and families in Washington State. The Supplemental Nutrition Assistance Program Education (SNAP-Ed) helps people with food insecurity increase access to healthy meals. At WSU Puyallup, staff work to support SNAP-Ed programing across the state of Washington through the development of programs, resources and trainings for SNAP-Ed staff.

Organic Farming Systems and Nutrient Management

The goal of our program is to build soil productivity, support local agriculture, protect water quality, and facilitate recycling of organic wastes, by applying soil science principles to agricultural, development, and waste management issues.

Ornamental Plant Pathology

The Ornamental Plant Pathology program conducts research relating to diseases of ornamental plants. Specifically, our program focuses on ornamental bulb crops, diseases and postharvest keepability of Christmas trees, and Phytophthora ramorum, the causal agent of sudden oak death and ramorum foliar blight.

Plant and Insect Diagnostic Laboratory

The WSU Puyallup Plant Diagnostic Lab provides one-on-one identification of both home and commercial pests. The clinic deals with over a thousand specimens per year. Clients are able to bring in samples of plants and insects for an accurate problem diagnosis.

Professional Education

Professional Education provides expert guidance and coordination in partnering with clients to deliver professional and workforce development opportunities. Whether it be a multi-course online training certificate, in-person workshops, or week-long professional conferences, we work with clients to deliver excellent content in a participant-friendly manner. WSU Professional Education has provided high-quality professional development opportunities throughout the country for more than 40 years. We offer full-service conference management, including program planning and budgeting, marketing, speaker logistics, venue and catering logistics, as well as registration, website services, and financial management.

Small Farms

With leadership from the statewide Small Farms Program, WSU’s Small Farms Team engages in Extension, research, and teaching activities that benefit small- and mid-sized family-owned farms. The 40 team members help our state’s growers manage the new realities of urban-influenced agriculture. These growers face development pressure, increased costs, and competitive global markets, but also enjoy advantages that come with smaller scale production. They can more quickly adapt to emerging markets, tend to be viewed positively by their communities, and are poised to benefit from increased demand for sustainably grown farm products. Team members represent a wide variety of specialties, and are based in WSU programs, state agencies and non-profit organizations.

Small Fruit Breeding and Genetics

The Small Fruit Breeding and Genetics Program works to develop new raspberry and strawberry cultivars adapted to the Pacific Northwest that have excellent flavor, high yields and improved disease resistance. The program also conducts research on genetic variation and cultivar responses. Research in the near future will be on the nutritional properties of raspberries, root rot tolerance and machine harvestability of raspberries.

Structural Pest IPM

The WSU Structural Pest IPM program trains professionals to reduce the number of inaccurate wood-destroying organism inspections and reduce the potential health risks from unnecessary or improper pesticide applications. A trained workforce of Structural Pest Inspectors and Pest Management Professionals will be more knowledgeable about identification of structural pests, conditions conducive to pest infestations, and integrated pest management (IPM) techniques. A Structural Pest Research and Demonstration Facility is located at WSU Puyallup. This facility offers unique opportunities for research and demonstration workshops related to structural pests and their management. In addition, it will provide both hands-on demonstration workshops and pre-license training classes for Structural Pest Inspectors, Pest Management Professionals, and other clientele.
