Non Technical Summary
The Washington State Integrated Pest Management (IPM) Extension Implementation Program (EIP) supports the CPPM EIP purpose of assuring the implementation of IPM through extension activities and coordination within our state and collaboration with other EIP grantees. Our goal is to disseminate IPM knowledge and foster adoption of IPM practices by building upon established, successful extension projects and developing new and improved modalities for outreach and education, working across disciplines and geographic regions to achieve educational synergies and reduce duplication of effort while increasing knowledge and practice of IPM among agricultural and urban pest management practitioners. In accordance with the National IPM Roadmap, the Washington State EIP for 2021-2024 seeks to improve cost-benefit outcomes for agricultural and urban audiences that adopt IPM practices, reduce potential human health risks, and minimize adverse environmental effects from pests and related management strategies. Our proposal addresses four of the EIP Primary Priorities and one Secondary Priority.Washington State produces over 250 crops and has a complex urban/rural interface. The state's IPM Extension Implementation Program is administered by Washington State University (WSU). The WSU EIP team represents a wide variety of cropping systems and communities across our state. The project is headquartered at the Irrigated Agriculture Research and Extension Center (IAREC) in Prosser, in south-central Washington. Other program sites (clockwise, from top left) are the Regional Small Farms Program (RSFP) in Port Angeles; the Northwest Research and Extension Center (NWREC) in Mount Vernon; the Puyallup Research and Extension Center (PREC); the Tree Fruit Research and Extension Center (TFREC) in Wenatchee; the Honey Bee and Pollinator Research, Extension, and Education Facility (HBPREEF) in Othello, the WSU main campus in Pullman, and the Franklin County Extension office in Pasco.

Goals / Objectives
The overall goal of our program is to increase IPM implementation among the agricultural and urban pest management practitioners of Washington State. Supporting objectives include preparation and dissemination of a variety of specific tools* based on scientific research to assist stakeholders in achieving greater sustainability, human and environmental safety, and positive economic returns; engaging stakeholders* and collaborative teams* in program implementation; and evaluating program success via specific feedback mechanisms* and milestones*. Our program aligns with 2021 CPPM project goals of Plant Protection Tactics and Tools (specifically "introduction of new pest management tactics for use in IPM systems"); Diversified IPM Systems (specifically "long-term sustainable solutions to pest management problems on a regional or national scale" via interstate partnerships); and IPM for Sustainable Communities (specifically, "application of IPM knowledge and expertise to address pest management challenges in non-traditional settings such as urban structures, landscapes and gardens"). Our program includes four EIP Primary Priorities (Agronomic Crops at 8% of total project budget, Communities 21%, Specialty Crops 44%, Pollinator Health 7%) and one secondary priority (Pesticide Applicators 11%) plus administrative coordination (9%, which includes program evaluation/survey support, annual reporting, and quarterly stakeholder newsletter).
Project Methods
Multimodal print and electronic content ill be developed and in-person an remote educaton mthod will be used to disseminate knowledge about IPM practices thatcan be emploed in Washington State communities and crops.

Outputs
Target Audience:Target audiences served by this project during this reporting period include: • Growers of tree fruits (incl. cherry, pear, apple, peach, plum, nectarine); wine and juice grapes; wheat, barley, and other small grains; hops; mint; alfalfa and alfalfa seed; potatoes, carrots, and onions; high-value specialty crops; berries • Members of the scientific community including entomologists, weed scientists, plant pathologists, nematologists, horitculturists • Commercial and hobbyist honey beekeepers and growers of crops dependent upon honey bee pollination services • Master Gardeners • Owners, managers, and workers on small farms, including those under organic or transition-to-organic status and those on the rural/urban interface • Home gardeners and the extension agents who serve them • Other practitioners of Integrated Pest Management Extension throughout the region and the nation Changes/Problems:There have been no major changes or problems. In the "What do you plan to do during the next reporting period to accomplish the goals?" subsection of the Accomplishments section of this report, we explained that we are utilizing this no-cost-extension year of the project primarily to expand the outreach to our small grain grower audience due to some additional alliances that have formed in the Pacific Northwest in this past project year. These new coalitions and cooperative efforts afford our small grains outreach team the opportunity to reach a wider audience than originally planned, therebymeeting a larger goal than originally set. What opportunities for training and professional development has the project provided?Our Extension IPM program offers many opportunities for students and staff to receive mentorship, training, and professional development. Students working with our team members during this project reporting period included (name, degree program, mentor); all were Washington State University students unless otherwise indicated. • Robert Czokajlo, Masters, Beers • Bernadette Gagnier, PhD, Moyer • Johnny Galvez, AA, Columbia Basin Community College (CBC), Waters • Rosalio Garza, AA, CBC, Waters • Alexa McDaniel, PhD, Moyer • Jackie Meza, BS, Waters • Delaney Shattuck, BS, Waters • Stephen Onayemi, PhD, Walsh • Srijana Shrestha, PhD, Miles • Callie Short, BS, Waters Several staff members, including postdoctoral associates, were also involved in Extension IPM as a part of this grant. Those who conducted substantial outreach on behalf of the WSU Extension IPM team this reporting period included (name, role / title, supervisor): • Dylan Beal, Postdoctoral Research Associate, Beers • Sally O'Neal, Research & Extension Communication Specialist, Walsh • Jenna Osiensky, Web & Events Manager, Lyon • Briana Price, Program Extension Coordinator, Hopkins • Peter Smytheman, Scientific Assistant, Beers • Ashley Spalding, Agricultural Extension Technician, Waters • Maddie Spets, Agricultural Extension Technician, Waters • Mark Thorne, Research Associate, Lyon How have the results been disseminated to communities of interest?The Washington State IPM Extension Implementation Program (EIP) is entirely focused on information dissemination. Its function is to support the USDA NIFA Crop Protection and Pest Management EIP purpose of assuming the implementation of IPM through extension activities and coordination within our state and collaboration with other EIP grantees. Toward that end, results have been disseminated via peer-reviewed journal articles, non-peer-reviewed publications including Extension publications and newsletters, conference presentations, field days, web content, social media, audio and video productions, blogs, podcasts, workshops, webinars, and one-on-one communications with stakeholders. Some, but not all, of those outreach modalities are listed in the Products and Other Products sections of this report and some are mentioned in the "What was accomplished under these goals" section above. What do you plan to do during the next reporting period to accomplish the goals?The vast majority of our goals have been met or exceeded. This final, no-cost-extension year of our project is primarily to allow for some follow-up on items already addressed. Specifically, additional activity is planned to address three as-yet-unmet goals within our IPM Implementation in Agronomic Crops priority area aimed at the growers of small grains (wheat, barley). The outreach regarding herbicide resistance management will be completed in conjuction with the two major work groups with which we have established partnerships over the last 18 months, Pacific Northwest Herbicide Resistance Initiative and Getting Rid of Weeds (GROW) IPM group. Projects underway to finalize the goal of increasing knowledge about managing specific troublesome weeds include two publications and additional web-based content (almost finished at the time of the report). Finally, the Fall 2024 and Spring 2025 calendars present ample opportunities to extend information about incorporating insecticides in the IPM program (including pests in stored grain and insect vectors of small grain diseases)
