Goals / Objectives
Our overarchinggoal is to disseminate integrated pest management (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.
Project Methods
The Washington State Integrated Pest Management (IPM) Extension Implementation Program (EIP) seeks to assure the implementation of IPM on the part of its target audiencesby 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. Key specific activities for each emphasis area follow.Administrative Coordination includes continuing periodic meetings between members of the IPM team and coordination of annual reports and plans of work. New initiatives include 1)enhanced emphasis on program evaluation and quantifiable outcomes via surveys developed and deployed in cooperation with Washington State University's Social and Economic Sciences Research Center and 2) development of a new WSU IPM website.Agronomic Crops methods include continuation of the successful Wheat Academy, Crop Diagnostic Clinic, and Alfalfa Seed School projects at which presentations are made and knowledge/practice assessments taken. New initiatives include development of an Herbicide Mechanism of Action decision support tool and refinement of pest managementand pollinator protection recommendations.Animal Agricultre methods include continuation of regular meetings with the Pacific Coast Shellfish Grower Association and refinement of recommendations for management of burrowing shrimp and Japanese eelgrass. New initiatives include a Shellfish Crop Pest Losses Survey and an update of the Pest Management Strategic Plan for bivalves.Community IPM education will continue management and operation of the Hortsense website for homeowners and Master Gardeners. New initiatives include addition of a beneficial insect and pollinator category with 35 fact sheets and 120 images, as well as a section on invasive pests with 10 fact sheets and 25 images.Specialty Crop projects include outreach in tree fruits, cranberry, grapes, hops, and vegetable row crops:expansion of mating disruption in codling moth (pest of apple) to include sterile insect releaseencouragement among cherry growers to adopt sampling techniques for spotted wing drosophila via winter meetings and site visitstracking of brown marmorated stinkbug and development of recommendations as this invasive pest moves from urban to agricultural areas of the statecontinuation ofCranberry Vineand Viticulture and Enology Extension Newsnewslettersfield days for cranberry, grape, potato, onion, carrot growersmaintenance and expansion of tree fruit, cranberry, hop,and grape websitesparticipation in and presentations at grower group meetings in all listed specialty cropsgrape grower education about membracid vectors ofGrapevine red blotch-associated virusand fungicide resistance developmentdeployment of recommendations for weed control, storage rot mitigation, and management of onion thrips andIris yellow spot virusin onion via formal presentations,farm visits, and weekly emails during the growing seasonaddressing cavity spot and root-knot nematode in carrots via germplasm evaluation and presentations at grower meetingseducation on grafting as a means of disease prevention, including development of a vegetable grafting manual, articles in popular agricultural press, and Powerpoint presentatoinsrevision of PMSPs for potatoes and bivalvesPollinator Health will emphasize resistance management in varroa mite, the leading best of honey bee and a transmitter of viruses leading to Colony Collapse Disorder. Site vists and formal presentations will be used to train beekepers in the use of sampling technology andacaracide rotation. Managed pollinator plans will be developed and published for at least 2 Washington State crops.Pesticide Applicator pre-certification and recertification educational programs will continue.

Target Audience:Our target audiences throughout this project, from its original inception in 2017 through its initial conclusion in 2021and continuing through the wrap-up activities of thefirst half of 2022, were pest management practitioners in agricultural and urban settings throughout the state of Washington and adjacent or affiliated states and regions, along with allied stakeholders (e.g., community members, distributors and end users of agricultural products, regulatory agencies, students, scientists). Changes/Problems: Nothing Reported What opportunities for training and professional development has the project provided?Opportunities for training and professional development took place when EIP team members, their staff members, and their students made presentations at grower group meetings (e.g., Hop Growers of America, Washington State Grape Society, Washington State Nursery and Landscape Association, Pacific Northwest Vegetable Association, Almond Growers of California, British Columbia Honey Producers Association, National Alfalfa & Forage Alliance, Washington State Potato Commission, Washington Mint Growers Association, Western Alfalfa Seed Growers), scientific conferences (American Phytopathological Society, Entomological Society of America, Weed Science Society of America), field days (e.g., wheat and small grains, onion, potato, hop, grape, beekeeper), and other venues (e.g., Washington State Department of Agriculture, US Environmental Protection Agency, WSU Foundation, various WSU courses). Additionally, members of the EIP team directly mentored 6 PhD graduate students, 6 MS graduate students, and 3 undergraduate students during this final project period. How have the results been disseminated to communities of interest?Results were disseminated via scientific journal articles, extension publications, blog posts, podcasts, Facebook pages, Twitter feeds, websites (both the team site at ipm.wsu.edu and sites specific to each crop and discipline), book chapters (specifically revised sections within the Pacific Northwest Insect / Plant Disease / Weed Handbooks), in-person and virtual conferences and meetings, webinars, fact sheets, newsletters and newsletter articles, listservs, and one-on-one interactions with target audience members. What do you plan to do during the next reporting period to accomplish the goals? Nothing Reported

Impacts
What was accomplished under these goals? The Washington State EIP team, under the leadership of Dr. Doug Walsh, continued to provide research-based tools, strategies, and recommendations to agricultural and urban pest management practitioners across the state toward the overall goals of increasing adoption of IPM practices, increasing sustainability, and improving crop or site conditions and outcomes. This project was largely complete at the end of the previous reporting period (8-31-2021, Progress Report submitted to NIFA via REEport 11/19/2021), but several loose ends were tied up in 4th quarter 2021 and 1st and 2nd quarters of 2022, including the publication of several articles and posting final research results on relevant university and industry websites.

Progress 09/01/19 to 08/31/20

Outputs
Target Audience:Generally speaking, our target audiencefor the entire project including this reporting period includes practitioners of pest management in urban and agricultural settings throughout the state of Washington and adjacent or affiliated states/regions, along with allied stakeholders (e.g., community members, end users of agricultural products, regulatory agencies, scientists). Specific audiences reached during this reporting period included: Tree fruit growers interested in managing mites, psylla, codling moth, spotted wing drosophila, little cherry disease, and other pests in fruit including apples, pears, cherries, nectarines, and plums. Beekeepers seeking to minimize colony damage from pests, predators, parasites, and Colony Collapse Disorder through novel methods including indoor hive storage and integrated varroa mite management. Wine and juice grape growers seeking to manage grape phylloxera, mealybug vectors, powdery mildew, and other grape pests in an integrated context, including management of fungicide resistance. Hop growers, researchers, merchants, and brewers interested in management of mites and other arthropods as well as downy and powdery mildews in a whole-farm IPM context. Growers of alfalfa, particularly alfalfa grown for seed, seeking to balance pollinator protection with pest management. Mint growers interested in impacts of crop irrigation and nutrition on the pest complex and its management. Wheat, barley and other small-grain growers seeking management strategies for troublesome dryland weeds. Growers of high-value specialty crops including tomatoes, eggplant, and watermelons interested in employing grafting as a means of increasing resistance to diseases such as verticillium wilt. Growers of onions, potatoes, carrots, and dry beans seeking best management practices for newer pests and diseases in their respective row crops. Citizen scientists interested in understanding and assisting with identification of beneficial bumble bees. Community members, householders, and Master Gardeners wishing to expand their knowledge of IPM and the identification of pests, beneficial organisms, and invasive species. Professional pesticide applicators seeking current knowledge and certification in sustainable management of lawn, turf, and other landscape pests in urban environments. Students (graduate and undergraduate) working with our team members to provide outreach education to the above audiences. Legislators and agency employees whose responsibilities include oversight of and/or funding of agricultural and/or urban pest management endeavors. Scientists and students including those practicing or studying entomology, plant pathology, weed science, horticulture, agronomy, and allied sciences toward a broad and holistic understanding of integrated pest management. Changes/Problems:The COVID-19 pandemic has restricted, cancelled, and/or changed the nature of Extension outreach activities in 2020. Virtual, electronic, distanced, and other novel outreach modalities are being used and are under further development at the time of this writing. Specialty Crops: A shortage of one of the SWD lure components caused a delay in deployment until late in the season, missing the critical period of early cherry harvest. An outbreak ofWestern X phytoplasmain sweet cherry has diverted attention away from SWD until some level of control has been achieved. Pollinator Health Due to the seasonality of beekeeping, opportunities for training commercial beekeepers are limited to a narrow window of time in the spring. While educational materials can be developed year-round, conducting training in real-time is a challenge. The pollinator team plans to address that issue in the coming year with the hiring of a postdocoral specialist who will focus on building capacity for training and outreach opportunities. Pesticide Applicators: In-person ecoPRO training did not prepare participants for the certification exam. Most of the instructors did not fully understand the expectations of the program or the exam. Through an exam review process it was determined that the exam had many inconsistencies with the expectations of the certification. Thus, there is a redirect in project work to study manual and exam rewrite and online training modules vs the initial project plan for in-person training. What opportunities for training and professional development has the project provided?Graduate and undergraduate students receiving mentorship from our EIPM team as they conducted IPM Extension outreach during this reporting period include (name, degree program, mentor): Connor Auth, MS, Hopkins Paul Bergeron, PhD, Beers Greta Dupuis, MS, Walsh Pinki Devi, PhD, Miles Jacob Fischer, MS, Lyon Jim Hepler, PhD, Beers Kelsi Jarosz, MS, Hopkins Dowen Jocson, PhD, Beers Adrian Marshall, PhD, Beers Jonathan O'Hearn, PhD, Walsh Stephen Onayemi, MS, Hopkins Saffet Sansar, MS, Hopkins Srijana Shrestha, MS, Miles Anna Webb, MS, Hopkins In addition to the many conference presentations listed in theProductssection made by members of the team (which provided training and professional development to those attending) or their graduate students and research staff (which provided training and professional development for both the presenter and the listeners), of particular note are entire conferences organized by members of the team, including the 94thannual Orchard Pest and Disease Management Conference (Beers, Program Chair), the Pacific Branch Entomological Society of America annual meeting (Beers, President), the Cryopreservation of Honey Bee Semen conference (Hopkins), the WSU Weed Science Tour (Lyon, Organizer), the WSU Wheat Academy (Lyon), Fungicide Resistance Management in Grapes workshop (Moyer), 2020 Powdery Mildew Management (Moyer), and the WSU Mount Vernon NWREC Field Day (Miles, Organizer). How have the results been disseminated to communities of interest?In addition to the publications, conference presentations, and other outreach materials and activities cited in theProductsandOther Productssections, many of our team members maintain a robust social media presence on platforms including Twitter and Facebook. Websites include http://ipm.wsu.edu,the overall website for the Washington State University IPM Extension Team http://smallgrains.wsu.edu for growers of wheat, barley, and other small grains http://tfrec.cahnrs.wsu.edu for tree fruit growers and orchard managers http://wine.wsu.edu for those studying wine and grapes and managing vineyards http://mtvernon.wsu.edu, the Northwestern Washington Research and Extension Center, with a focus on the crops west of the Cascade Mountains http://iarec.wsu.edu, the Irrigated Agriculture Research and Extension Center, with a focus on agronomic and specialty crops grown in the Columbia Basin and throughout eastern Washington's agricultural acreage http://bees.wsu.edu for bee keepers and those seeking to balance pollinator preservation with crop production and other activities What do you plan to do during the next reporting period to accomplish the goals?Priority Area: Agronomic Crops Additional podcasts, regional extension publications, and articles planned on weeds of concern Presentations on MOAs and resistance planned for Wheat Academy, blog, and podcast Active population and expansion of Herbicide Resistant Weeds Map Emphasis on harvest weed seed control will continue print, oral, and electronic communications Invited presentations scheduled for alfalfa seed grower meetings and US EPA Alfalfa seed growers who were surveyed in April 2018 regarding their knowledge and adoption of IPM practices will be surveyed in April 2021 to quantify changes in knowledge and behavior Priority Area: Communities Continue successful program of annual fact sheet updating throughout website Beneficial insect and pollinator fact sheets to be updated ~20 new fact sheets will be added to beneficials/pollinators portal Addition of an invasive species category (portal) with 20 fact sheets to engage Master Gardeners and home gardeners as first detectors Priority Area: Specialty Crops Hop Growers and Stakeholders Walsh will host brewers at IAREC in September for hands-on evaluation of hop varieties A revised Pest Management Strategic Plan will be developed in the first half of 2021 IPM presentations will be made to WA Hop Commission and American Hop Convention A virtual (distance learning) field day will be held covering monitoring for hop aphids, spider mites, and downy and powdery mildews Vegetable Growers Onion Field Day and Onion Cultivar Demonstration will be held Presentations will be made at the Pacific Northwest Vegetable Association Conference One-on-one meetings will be held with Columbia Basin vegetable growers design IPM strategies for the coming growing season Grafting Manual: How to Produce Grafted Vegetable Plantsand narrated PowerPoint presentations will be promoted to Master Gardeners and county extension educators Grafting instructions targeted to plant propagators will be developed in Spanish Grafting curriculum for high school plant sciences will be developed Our websitehttp://vegetables.wsu.edu/graftingVegetables.htmlwill be updated Potato growers who took part in our formal survey on IPM knowledge and adoption in December 2018/January 2019 will be surveyed again in December 2020/January 2021 to assess progress of our outreach program Tree Fruit Growers Work remotely on technology transfer among growers in the PNW and California Publish articles and make presentations on novel controls pioneered in 2019 UpdateCrop Protection Guide; collaborate onGood Fruit Growerarticles Address 2019 increases in SWD/BMSB through increased extension/distance learning Grape Growers Workshops emphasizing pest and disease scouting, identification, and pest management program design will be held.

Progress 09/01/18 to 08/31/19

Outputs
Target Audience:Audiences reached during this period included: hop growers, researchers, merchants, and brewers interested in mite management and miticide resistance, management of downy and powdery mildews in a whole-farm IPM context, efficacies of newer miticides and insecticides, and interactions between production activities (including irrigation and nutrient inputs)and pest management mint growers and end users seeking ways to monitor for mint root borer and integrate its treatment into their IPM program citizen scientists with an interest in identifying, monitoring, and protecting bumble bees growers of alfalfa produced for seed interested in balancing protection of native and managed pollinators with pest management regulatory agencies seeking understanding of native and managed pollinators and ways of protecting them growers of wheat and other small grains interested in traditional and novel weed control methodologies including weed seed control and use of tillage in an integrated weed management program grape growers and viticulture students seeking training on field scouting, identification of diseases, fungicide resistance management, and designing sustainable spray programs tree fruit (including pear, cherry, apple) growers seeking to improve control of pear psylla, codling moth, and brown marmorated stink bugs in their orchards by incorporating novel (including non-chemical) IPM tactics beekeepers concerned about Colony Collapse Disorder willing to monitor for and control varroa mites shellfish producers seeking ways to control burrowing shrimp, decrease sediment turbidity, and manage Japanese eelgrass in an integrated program cranberry growers concerned about the rise of tipworm populations and increasing incidence of storage rots growers of high-value vegetable row crops interested in incorporating grafting as a means of increasing pest resistance properties, as well as educators at all levels wishing to learn grafting techniques and teach them to others growers of onions, potatoes, and carrots seeking best management practices for newer pests and diseases in their crops homeowners and Master Gardeners wishing to expand their knowledge of IPM and learn about conservation and identification of beneficial arthropods professional pesticide applicators seeking current knowledge and certification in sustainable management of lawn, turf, and other landscape pestsin urban environments K-12 students taking part in hands-on workshops undergraduate and graduate university students working with our team members to provide outreach education to the above audiences Changes/Problems:The winter of 2018-2019 was particularly hard in the Pacific Northwest, with late and prolonged snowfall lasting well into March. This provided logistical challenges for some of our team's winter workshops, but in every instance the challenges were met and overcome, whether by rescheduling, reaching out to attendees using alternate approaches, or a combination of both. Formal emailed and mailed surveys of IPM knowledge and activity were originally planned in alfalfa seed, onion, potato,tree fruit and hop in cooperation with the WSU Social and Economic Sciences Research Center (SESRC). Surveys took place on schedule in alfalfa seed, onion, and potato. Due to a combination of changes in program focus (from spotted wing drosophila emphasis to codling moth and stink bug emphasis) and lack of well-maintained mailing lists on the part of tree fruit industry organizations, the formal tree fruit survey was not conducted. Instead, measures of knowledge and activity changes among tree fruit growers with respect to IPM are being taken and will continue to be taken at conferences, workshops, and field days. Given the variety of pests and variety of tree fruits addressed by our outreach, this approach will likely prove more insightful than attempting a "one-size-fits-all" survey of all tree fruit growers. Regarding hops, we determined in FY17 that it was more cost effective and would reduce duplication of effort if we collaborated on a survey already funded and in place via Oregon State University and USDA-ARS to determine knowledge and activity changes among hop growers with respect to IPM across the Pacific Northwest. Dollars originally slated for the hop and tree fruit surveys have been redirected into costs associated with these alternate surveys. What opportunities for training and professional development has the project provided?Graduate and undergraduate students receiving mentorship from our EIPM Team as they conducted IPM Extension outreach during this reporting period included (name, degree program, mentor): Jonathan O'Hearn, PhD, Walsh Adrian Marshal, PhD, Beers Adekunle Adasanya, PhD, Walsh Jacob Fischer, MS, Lyon Alexa McDaniel, PhD, Moyer Pinki Devi, PhD, Miles Abagail Attavar, PhD, Miles James Hepler, PhD, Beers Joshua Milnes, MS, Beers Moyer's "Viticulture Intern Boot Camp" (May 30, 2019) specifically targeted the next generation of grape growers, training them in IPM principles including pest and disease identification and designing of IPM programs. Miles' "train the trainer" and K-12 curricula described in the Other Products section of this report provided training and mentorship for youth and adults. Graduate students, postdoctoral researchers, and technical staff attended professional conferences and workshops in their field including those of the Entomological Society of America, American Phytopathological Society, and Weed Science Society of America. How have the results been disseminated to communities of interest?In addition to the publications, conference presentations, and other outreach materials cited in the Products and Other Products sections: Walsh hosted members and guests of the national Hop Research Council at WSU Prosser Irrigated Agriculture Research and Extension Center (IAREC) July 24-25, 2018 for presentations and a tour of the research hop yards, greenhouses, drying faclities, laboratory, brewing facilities and Clean Plant Center Northwest. Walsh held an alfalfa seed field day in June 2018 and will hold another June 18, 2019, in Touchet. Patten conducted a Cranberry Field Day in Long Beach, WA, at the Pacific Coast Cranberry Research Facility on August 1. Lyon's student (Fischer) has developed presentations on his work in controlling rush skeletonweed during fallow and is in the process of presenting them to a variety of target audiences interested in weed control in small grains. Beers WA-SIR and BMSBprograms received print and broadcast media coverage. Waters hosts and/or participates in several onion, potato, and carrot field days annually. What do you plan to do during the next reporting period to accomplish the goals?Walsh will work with alfalfa seed growers across the west to enhance pollinator protection in an IPM context. Lyon will focus on herbicide resistance and harvest weed seed control. Foss will contractwith a programmer to create a portal for Invasive Species on the Hortsense website. Beers will expand her sterile insect reslease (WA-SIR) program and assess results in codling moth management as well as maintaining her BMSB location website. Moyer will continue her work in fungicide resistance management on multiple fronts including face-to-face conferences and field days, social media, and printed and electronic resources. O'Neal will produce a revision of IPM field guides for wine grapes and hops. Waters will focus on integrating disease (viral, bacterial, fungal) management with arthropod management, advancing varieties with improved pest resistance, and educating onion, potato, and carrot growers on pest mamagement implications of their fertility programs. Miles will expand her work in vegetable grafting as a means for disease management, including additional train-the-trainer programs. Hopkins will conclude his varroa mite sampling and awareness training and assess beekeeper adoption of the process. Foss will produce two training videos on sustainable landscape practices and four training modules for ecoPRO Sustainable Landscape Professional certification.

Progress 09/01/17 to 08/31/18

Outputs
Target Audience:Audiences reached during this reporting period include: wine grape growers who experience powdery and downy mildews in their crop and may use fungicides to manage them graduate students, Master Gardeners, and vegetable extension personnel interested in teaching grafting techniques as a means for improving pest resistance, stress tolerance, and marketing characteristics in eggplant, melons, and other crops carrot, onion, potato, and other vegetable growers in Washington, Oregon, Arizona, and Michigan concerned with arthropod and disease pest management the US Environmental Protection Agency regarding pollinator protection in the context of integrated pest management in alfalfa grown for seed Pacific Northwest dryland wehat growers who experience problems with weedy mustard species in their crop hop growers, researchers, merchants, and brewers interested in hop breeding for pest resistance, managing miticide resistance, efficacies of newer miticides and insecticides, and interactions between plant nutrition and integrated pest management (IPM) shellfish growers concerned about controlling burrowing shrimpand regulatory agencies (including the Army Corps of Engineers and Washington Department of Ecology) concernedabout environmental impacts of pesticides used to control this pest of commercial oyster and clam beds urban pesticide applicators in western Washington who apply pesticides in parks and public spaces and need to understand the spread of Ramorum blight (AKA Sudden Oak Death) in the region homeowners who may encounter brown marmorated stink bug, a potentially serious pest of agricultural crops Changes/Problems:We had intended to develop and deploy IPM surveys in six crops in Year 1, but have only deployed two at this writing (alfalfa seed and wine grape). A third (sweet cherry) has been developed, but obtaining an up-to-date, comprehensive mailing list for growers has proven challenging; that task is underway and the survey will be deployed as soon as we obtain and validate the list. Surveys for onion and potato growers are under development. A planned survey for hops was removed from our plan of work due to a similar survey being taken by USDA-ARS the previous spring. We have obtained those questions and results and will use this as our baseline survey, planning a followup in two years. What opportunities for training and professional development has the project provided?Wheat growers had the opportunity for training and professional development via Lyons' Wheat Academy seminar series in Pullman and talks on herbicide resistance in Connell and Waterville as well as a field tour scheduled for June 13, 2018. Growers of pulse crops (dry peas, lentils, and chickpeas) learned about weed control at meetings in Pasco and Walla Walla and have access to a Herbicide Mechanism of Action tool on the USA Dry Pea and Lentil Council website. Graduate students presented posters, made presentations, and had articles published in peer-reviewed journals as well as attending and learning about their individual disciplines at professional meetings such as the Entomological Society of America and American Phytopathology Society. Master Gardeners and staff at the Northwest Research and Extension Center (NWREC) received hands-on training in vegetable grafting including learning how to teach the pest management strategy to others. Shellfish and cranberry growers had the opportunity to learn about the latest IPM recommendations, including aquatic weed management. Growers, Master Gardeners, and community college studentslearned about IPM in potatoes, carrots, and onionsin a variety of forums. A December summit in Napa, CA, presented the opportunity for Extension experts, growers, consultants, chemical companies and other wine industry stakeholders to exchange ideas and learn about fungicide resistance management in wine grapes. Professional development and training opportunities were provided to beekeepers on how to utilize a field shaker device to enhance their protection of honeybee pollinators. How have the results been disseminated to communities of interest?Wheat information via talks in Pullman, Connell, and Waterville, via a planned field day in June, via the WSU Small Grains website (smallgrains.wsu.edu) and via publication PNW703. Pulse crop information via talks in Pasco (PNW Vegetable Association annual meeting) and Walla Walla (Blue Mountain Seeds annual meeting) and via the USA Dry Pea and Lentil Council website (usapulses.org). Articles have been published in newsletters, popular press, Extension bulletins, fact sheets, and peer-reviewed journals. Talks were given to hop growers at Washington State Hop Commission and Hop Industry Council meetings in fall and early winter of 2017 and at the American Hop Convention in January 2018; content has been published on the Hop Growers of America website (usahops.org). A train-the-trainer curriculum was presented to Master Gardeners and NWREC. Shellfish information was disseminated via workshops, meetings, field days, presentations at the National Shellfish Association Conference, and scientific journals. Cranberry results were disseminated via workshops, newsletter articles, Extension publications, and journal articles. Strides in IPM awareness and adoption, balanced with protection of crucial pollinators, was discussed in face-to-face meetings with the US Environmental Protection Agency's Bereau of Economic Analysis Division in February 2018, which was covered in the Capital Press newspaper.Numerous workshops and conference presentations were made to the potato, onion, and other vegetable industries. One-on-one farm visits were made to many target audience members. Guest presentations in university and community college courses were made. Invited presentations were made to grower groups at their board meetings and other gatherings. Field days were conducted in vegetable row crops. Meetings (including the Washington Winegrowers annual meeting in February), newsletter articles, fieldd days, and classroom presentations were among the means for disseminating wine grape IPM information, particularly regarding management of fungicide resistance. This outreach received popular press attention in several articles in Good Fruit Grower magazine. Beekeeper outreach took place through site visits to four large-scale commercial beekeepers and through presentations at beekeeping associations.All audiences had the ability to subscribe to the first quarterly edition of the IPM Update newsletter on the team's website (ipm.wsu.edu) or to read it on the website as a non-subsriber. What do you plan to do during the next reporting period to accomplish the goals?The sweet cherry growers survey developed in this period will be deployed in the next period. Surveys for potato and onion growers will be developed. The video explaining use of the Herbicide Mechanism of Action Tool for pulse crop growers will be posted on the USA Dry Pea and Lentil Council website to reach additional users. The online Vegetable Grafting Manual will be completed and its availability will be publicized on WSU websites including vegetables.wsu.edu and the national vegetable grafting website vegetablegrafting.org. The varroa mite program will be expanded to additional commercial operations and also to hobby beekeepers. All team members will continue their program of field days, popular and scientific article development, publishing of Extension bulletins, workshops, classroom presentations, and presentations at conferences and commodity meetings.The team will continue to prepare and disseminate quarterly activity updates on the ipm.wsu.edu website and to subscribers who have elected to receive these updates.

Impacts
What was accomplished under these goals? Information on integrated weed management, fallow weed management, identifying and managing insect pests, effect of soil pH on wheat diseases, herbicide resistance management, and diseases/disease disorders were communicated to wheat and small grain growers. Information on weed control and managing herbicide resistance was communicated to growers of pulse crops (dry peas, lentils, chickpeas). Entomologists nationally and internationally learned about work done with the Washington State Department of Transportation to assess vehicular traffic impacts on native pollinators and subsequent alfalfa seed yields in the Walla Walla Valley. Regulatory agencies and growers of alfalfa seed learned about balancing pollinator protection with pest management. An online Vegetable Grafting Manual was developed and nearly completed (all but one chapter). Shellfish IPM concepts were shared with Washington State lawmakers as well as withshellfish growers regionally and nationwide. Cranberry growers received information about emerging IPM recommendations. Potato, onion, corn,and carrot growers received IPM instruction for their crops, specifically in management of Lygus and other arthropods (potato), in identification ofdiseases and insects (carrot), and in managing thrips and Iris yellow spot virus (onions). Managing fungicide resistance in wine grapes, particularly with respect to those fungicides used to manage powdery mildew, was a topic of discussion and educational outreach in a variety of forums. Commercial beekeepers were trained in devices and methods to check their hives for infestations of varroa mites, a major pest of pollinating honeybees.General updates on activities of Washington's Extension IPM Team were made available via quarterly e-newsletters. A new WSU IPM website was created and launched.
