Accomplishments

The overarching goal of the WERA1017 committee is to enhance adoption of Integrated Pest Management (IPM) that improves economic, environmental, and social outcomes within the western states and Pacific Basin Territories of the United States. The group’s collaboration efforts continue to highlight the value of a joint, comprehensive approach to address IPM and to serve as a nexus for communication and information sharing with broader regional and national entities. The following accomplishments (reported by Alaska, Arizona, California, Colorado, Hawaii, Idaho, Montana, Nevada, New Mexico, Oregon, Utah, Washington, and Wyoming) were completed in relation to the WERA1017 Project Objectives during the reporting period between September 19, 2024, and March 3, 2025:

Objective 1. Increase participants’ skills, knowledge, and awareness of regional/national IPM issues, systems, and strategies.

WERA1017 participants benefit from continuing opportunities to share knowledge, strategies, ideas, resources, and outcomes. The networking and “learning benefits” of the group allow IPM coordinators and specialists to bring these valuable lessons and connections back to individual programs and stakeholders, expanding not only regional/national IPM awareness but the tools, resources, and knowledge necessary to assist with positive outcomes. The impact of regional and national outcomes remains important to all constituents, and during this reporting period, the WERA1017 group has worked closely with the Southern and Northeastern IPM Centers for consistency in reporting outcomes and evaluation. We continue to learn and expand our regional and national IPM efforts with each meeting, working group, and collaboration.

Objective 2. Serve as a platform and feedback body to promote Multi-State and transdisciplinary IPM research and Extension, and help connect outputs/outcomes with key user groups.

WERA1017 participates in projects across the West that continue to expand IPM knowledge and awareness and include every IPM Priority Project Area: IPM Implementation in Communities including Housing and Schools, IPM Implementation in Specialty Crops, IPM for Pesticide Applicators, IPM Implementation in Agronomic Crops, IPM Support for Pest Diagnostic Facilities, IPM for Pollinator Health, IPM in Public Health, and IPM Implementation in Animal Agriculture. During this reporting period, WERA1017 participants contributed to 405 publications, nearly 4,000 diagnostic services reports, 554 Extension presentations, and over 300 workshops, webinars, and commodity/grower meetings (see details below). In total, the group’s outreach efforts had a direct impact on over 51,000 stakeholders (field days, workshops, professional development, webinars, etc.) and contributed to an indirect impact of over 60,000,000 people (newsletter/Listserv subscribers, website views, podcast listens, etc.). WERA1017 members were also instrumental in the leadership, planning, and execution of the 11th International IPM Symposium.

Objective 3. Enhance collaboration, sharing of ideas, and creation of regional outputs such as Multi-State grants and shared outreach materials.

The following collaborations, facilitated through WERA1017 interactions, provide a few examples of how we are helping to extend the reach and impact of our work as Land Grant institutions and minimize duplication of effort:

Current collaborative projects in Pesticide Education include pesticide registration comment coordination (Arizona, New Mexico, Nevada) and ESA training for producers/publications (Arizona, Oregon, Utah). Multi-state pesticide applicator trainings have expanded topics and speakers to extend resources and opportunities to stakeholders. In similar efforts, fact sheets and extension materials are also shared across state IPM programs to increase the resources and expertise available to stakeholders.
WERA1017 members (Colorado, Oregon, Utah, Idaho, Montana, Wyoming, Arizona) have collaborated for grant funding and initiated an extensive regional education and outreach campaign for Emerald ash borer (EAB), Agrilus planipennis(Coleoptera: Buprestidae) across Colorado, Oregon, Utah, Wyoming, and Montana. EAB is an invasive, highly injurious, and devastating pest to ash trees (Fraxinus ) throughout North America. This insect is a key problem in urban and rural forest settings and destroys 100% of ash trees in just a few years if the infestation is undetected or left unaddressed. The EAB team is collaborating for prevention and management strategies through working group meetings, workshops, community events, and print, digital, and social media to educate and increase adoption of IPM practices among homeowners and municipalities.
"Cultivating Healthy Plants: An IPM Webinar Series," is a collaboration between Utah State University, University of Nevada - Reno, University of Idaho, and Montana State University. Oregon State University was also a collaborator for one of the webinars. For the five webinars during the reporting period, 2,036 individuals participated live, and there were 1,035 additional views of the recorded webinars. Participation includes private industry, Extension, State/Federal Agencies, research professionals, landscape professionals, private homeowners, and commercial growers. The group has also established a central place to house the webinar series and associated content (https://www.youtube.com/@CultivatingHealthyPlants, https://www.cultivatinghealthyplants.org/) and currently has 239 subscribers to the new Cultivating Healthy Plants YouTube channel.
Current collaborative projects in specialty crops include Vegetable IPM collaboration (Arizona and California); Cotton IPM collaboration (Arizona and California); crop pest losses and impact assessment (Arizona and Oregon); and the Intermountain Commercial Tree Fruit Production Guide (Utah, Montana, Colorado, Idaho).
WERA1017 members participate in valuable regional efforts including the Pulse Crop Working Group, the Western Invasive Plant Risk Evaluation Network, the NCERA 224 multi-state working group focused on IPM of ornamental crops, the S1084 multi-state working group focused on hemp pest suppression (WERA Hemp), the Western Sugar Beet Pest Management Strategic Planning, the Western Pear Pest Management Survey, Regional Wheat IPM Implementation Groups, multi-state Palmer Amaranth Task Force, Northern Plains Weed Management Group, Great Plains Diagnostic Network, National Urban Extension Leaders (NUEL), National Urban Research and Extension Center (NUREC), NRSP – Temp 12 – National Research Support Project, WERA77 – Weeds in winter wheat, W5147 – Microbes in plants, and many other regional affiliations.

Objective 4. Improve coordination of IPM research and outreach programs that address on-going, emerging, and other critical pest and related environmental issues.

Coordination efforts resulting from WERA1017 help to align and synchronize IPM research and outreach programming across the region. For example, while discussing the Emerald Ash Borer collaboration (described above) in our most recent meeting, the group will expand to include two additional states in the outreach efforts for this emerging pest in the West. Sharing of IPM research and resources is a priority for each WERA1017 member, and the learning benefits to IPM coordinators and programs are hard to quantify but very impactful to pest management and related environmental issues. The group will also continue to coordinate with the Southern and Northeastern IPM Centers to assist with surveys and reporting platforms that fit easily into the national framework and can be built upon to better understand long term outcomes and impacts.

Plans for the coming year: WERA1017 will continue to collaborate on currently funded regional projects as described above. The next WERA1017 meeting will be hosted in Wyoming in September 2026. The group plans to expand involvement in the Western IPM Newsletter with a new “Resources Spotlight” to increase access to new, novel, and timely regional resources. The list-serve will also be expanded for increased use to facilitate discussion and seek out existing resources.

Continuation of plans from previous report: Some members of WERA-1017 as well as Western IPM Center staff have committed to putting together a series of written works that will document what an IPM Coordinator is and does and how this influences the development of state IPM programs. This will serve both as onboarding information for new IPM Coordinators and as a means for IPM Coordinators to educate their own university administration about their role and function supporting state IPM while maintaining connections to a federal network and addressing federal priorities.

Impacts

During this six month reporting period, WERA1017 participants contributed to 405 publications, nearly 4,000 diagnostic services reports, 554 Extension presentations, and over 300 workshops, webinars, and commodity/grower meetings. In total, the group’s outreach efforts had a direct impact on over 51,000 stakeholders (field days, workshops, professional development, webinars, etc.) and contributed to an indirect impact of over 60,000,000 people (newsletter/Listserv subscribers, website views, podcast listens, etc.). The WERA1017 participants have also leveraged over $15 million from 32 grants, contracts, and other resources to expand IPM research, programming, and stakeholder collaboration. These impacts were made possible through collaboration of the WERA1017 group, and impact statements provided by each individual participating state are provided below.
Arizona: The Arizona Pest Management Center (APMC) develops, implements, and evaluates high-impact Integrated Pest Management (IPM) programs to meet the needs of growers, communities, and public health agencies. With a focus on agricultural crops and communities, APMC delivers science-based strategies that improve pest control while reducing environmental, human health, and economic risks. Our team helped growers implement reduced-risk insecticide programs that led to record-low pesticide use in cotton, saving an estimated $600 million and preventing 40 million pounds of insecticide from entering the environment over the last 29 years. Today 90% of sprayed acres in cotton and 60% in lettuce are with fully selective insecticides that are safe to non-target natural enemies like predators and pollinators. Our programs also protect communities. Public health IPM outreach boosted knowledge and reduced pesticide exposure in communities and urban settings including 16 of 22 federally recognized tribes. In tribal nations, mosquito-related costs dropped by $18,000 per season thanks to IPM-based vector control. These outcomes are backed by strong collaborations with growers, tribal partners, and stakeholders across Arizona. By increasing adoption of proven IPM tactics, APMC ensures practical, cost-effective pest solutions that safeguard Arizona’s agricultural productivity and public health.
California: In 2022, an analysis by economists at Michigan State University documented that the IR-4 program added $8.97 billion to the US economy by supporting pesticide registrations on specialty crops. The Western Region IR-4 Regional Field Coordinator stated that there are about 90-100 research trials conducted in California each year and UC Advisors and Specialists conduct more than 90% of them. California produces 43.7% (by dollar value) of US specialty crops. Therefore, the California projects prioritized at the IR-4 Food Use Workshop, which led to field trials conducted by UC Advisors and Specialists, contributed to a $3.92 billion increase in GDP. Data from the Pest Management Practices surveys conducted annually by National Agriculture Statistics Service were used to estimate adoption of integrated pest management (IPM) in California. Surveys indicate 75% or greater use rates by acreage of eleven pest management practices in vegetable crop production in 2022 and seven pest management practices in fruit and nut crop production in 2021. Integrated pest management is widely adopted in California vegetable and fruit and nut crop production.
Colorado: Impacts of our work in Colorado on agronomic crops include increase in knowledge and use of resistant crop varieties, suppress wheat pests such as wheat stem sawfly and wheat viruses, improved application of cultural controls to suppress a key pest in quinoa owing to development of effective pest monitoring, and improved stewardship of pesticide technologies available to suppress corn earworm. Adoption of resistant varieties and cultural control methods to suppress key pests in specialty crops has reduced pesticide use and costs associated with them, and improved profitability of fruit and vegetable production. A coordinated effort on emerald ash response will result in adoption of IPM to manage the invasive pests in urban landscapes.
Hawaii: A list was developed of high-risk species with potential for accidental introduction to Hawaii. This compilation supports proactive management strategies for potential pest introductions to Hawaii, leveraging publications from institutions actively managing these species. Key surveillance resources include USDA PestLens, the Global Invasive Species Database, and the Hawaii Invasive Species Council. The current list includes 9 species of insects and nematodes of high concern. The Crop Knowledge Master website is undergoing ongoing updates: completed the core structure, focusing on the navigation framework and organizing the menus and submenus where detailed information pages for crops, pests, and diseases will be located. From the homepage, users can access the content by selecting from four main categories: crop, pest, disease, or scientific name. Each of these categories is further divided into submenus for better organization. For example, crops are grouped by common types such as fruits or vegetables, while pests are categorized into groups like ants or scales. Additionally, all entries within these menus, including those under the scientific name category, are arranged alphabetically for intuitive browsing. In the scientific name menu, users can scroll through every pest or disease listed in alphabetical order based on the first letter of their genus. Other than building the framework and interface, the general design of the website is being upgraded. Because the older one was entirely in html, its design possibilities were limited. With the updated website we can make it more visibly appealing and easier to navigate. A combination of the modules provided by our content management system (CMS) from EVOQ DNN and custom written html to create the menus, buttons, links, dropdowns, tables, and other components of the website, are employed to this end. New invasive pests were surveyed in Hawaii: Ramie moth, Arcte coerula, pest of mamaki tea plants, and wild Pipturus plants. Expanded range was documented - widespread on Oahu. The role of parasitoids and predators in restricting this insect is being quantified. The Hawaii IPM program provided progress updates to Hawaii Coffee Growers Association and Kauai coffee growers on biological control of coffee berry borer, Hypothenemis hampei. Analyzed Invasive Invertebrate Pest Introductions and Trade Pathways in Hawaii using data on pest introduction to Hawaii, 20023-2023.
Idaho: The Idaho group of WERA1017 aims to improve IPM education and implementation success. This program reaches tens of thousands of stakeholders ranging from homeowners to large scale agricultural producers. One area of focus is pest monitoring. Our team monitors dozens of Idaho’s primary pests across the state, providing real-time data and actionable advice. Subscribers to the PNW Pest Alert indicated their use of the system resulted in managing pests more effectively (57%), increased awareness of pest presence (81%), increased timeliness of pesticide applications (64%), increased scouting (58%) and increased awareness of pest spread (59%). Subscribers widely shared recommendations (73%), spreading the impact of this program. In addition to helping stakeholders monitor pests, our team also helps stakeholders with their ability to identify pests. Our diagnostic lab processes over 700 samples per year, and our Idaho Insect Identification site provides an additional 200+ identifications per year. Furthermore, we implemented a new educational program bringing live specimens of insects and diseases to stakeholders to facilitate better hands-on learning surrounding pest identification. This program, which reached over 600 participants, increased identification confidence of participants for insects (+0.6 mean confidence, p = 0.00028), diseases (+0.32 mean confidence, p = 0.058), and nematodes (+1.04 mean confidence, p = 8.21e-07).
Montana: In the past reporting period (9/1/2024-3/5/2025), the Montana IPM Team published 51 peer reviewed journal articles, extension publications or conference papers, gave 141 presentations (7,588 participants), and had 15 appearances on Montana Ag Live with Montana PBS (~15,000 viewers/episode). Surveys indicate a 30% or more average gain in knowledge after attending programing across priority areas including a greater understanding of urban pests and better awareness of new and establishing pests. These extension activities continue, and specialists continue to present research to a variety of stakeholders to develop a better understanding and IPM implementation throughout the state. Outcomes include weed and pathogen prevention, improved management of pests through IPM in urban settings and on over one million cropland acres, and more sustainable communities. In 2024, the Schutter Diagnostic Laboratory processed and reported on 846 plant disease diagnostic samples, 679 arthropod samples, and 288 plant/weed identification samples. Samples were received from 49 Montana counties and 4 additional states, and 55% of all samples were Extension related. In October, the 2024 Pest Management Tour was held over three days at eight locations across Montana with 237 attendees. We observed a 35% average gain in knowledge across all IPM subject areas when attendees rated their knowledge before and after the event. This saved Montana applicators a conservative estimate of millions of dollars due to increased effectiveness in managing pests across 469,746 acres as indicated in surveys to attendees. A multi-disciplinary group of entomologists and IPM specialists held the first "Entomology Day." This full-day educational "train the trainer" style workshop centered on the identification, sampling, and best management practices for common agricultural and kitchen garden arthropod pests. A post-workshop evaluation form was given to participants, and 100% of respondents would recommend the workshop to someone else. Palmer Amaranth Task Force early detection and rapid response plans continue to help with early detection of populations, making containment easier. More plants were identified this year in Carter County, but the rapid response plan that brings together Extension, Schutter Diagnostic Lab, and the Montana Department of Agriculture has eliminated seed set in fields. This continued prevention has the potential to save Montana producers millions of dollars.
Nevada: The University of Nevada, Reno Extension's Integrated Pest Management (IPM) and Pesticide Safety programs improve adoption of IPM practices in Nevada's urban areas, reducing the impacts of pesticide contamination in Nevada waterways. Educational products and programs are offered through both online and in-person formats to reach key Nevada audiences, including private citizens, Master Gardeners, certified pesticide applicators, and green industry professionals. In our Cultivating Healthy Plants IPM webinars, 90% of participants said they plan to implement at least one practice they learned. In our NevadaScapes program, which teaches homeowners sustainable residential landscape design with a strong focus on IPM practices and water quality protection, participants’ mean knowledge increase has averaged 43.7% over the past three years. Pesticide applicators from our fall 2024 workshop said the following: “This was a productive use of my time,” “One of the best workshops in the past 7 years,” and “Great webinars for remote locations.” These are just a few of the short-term impacts, but over 10 years of our programming we have also seen long-term impacts. Water quality studies show a significant decrease in pesticide residues in Nevada waterways, despite population growth.
New Mexico: New Mexico currently has approximately 2,800 private applicators and 2,200 commercial/public applicators that have a New Mexico Department of Agriculture (NMDA) issued pesticide license. State law requires that 4 to 5 hours of continuing education units (CEU’s) either be earned yearly (public applicators) or every 5 years (private applicators). Therefore, there is a strong need to provide those CEU credited pesticide applicator trainings on a yearly basis to those stakeholders. This year, an on-demand online option for pesticide applicator training was offered to make training more convenient in this 5th largest state. In addition, for those who prefer in person trainings eight in person pesticide applicator trainings were offered across New Mexico. The Pesticide Safety Education and Applicator Trainings reached over 650 pesticide licensed individuals through the combination of in person and on-demand trainings. Through recertifying those current pesticide applicators with an average annual salary of $42,089.00, this program added or maintained over $27,000,000 to New Mexico's economy.
Oregon: The Oregon IPM Center rebranded as such in 2022, thus we are making progress highlighting relatively new signature programs. Here https://agsci.oregonstate.edu/oipmc/about-oregon-ipm-center we are building capacity by creating Impact Statement per program, that later will be added into the National IPM Data Base. So far, we have two Impact statements: IPM communication https://agsci.oregonstate.edu/sites/agscid7/files/media/impact_statement_newsletter_final_version_12.20.2024.pdf and solve pest problems https://agsci.oregonstate.edu/sites/agscid7/files/media/ipm_impact_statement_spp_final_01.21.2025.pdf
Utah: The Utah IPM Program provides a wide array of outreach approaches, from traditional to novel. In 2024, one such program was the addition of invasive pest awareness. Partnering with the Utah Department of Agriculture and Food, the First Detector program provided a 6-week course and pest monitoring supplies to 37 participants. Tasked with seeking out non-native pests, participants submitted almost 150 detections and 210 images. Social media posts and email check-ins kept the first detectors engaged throughout the season.
Washington: The Washington State IPM extension team seeks to increase IPM implementation across the state. During this reporting period, knowledge of IPM practices and principals was increased among the following target audiences: producers of alfalfa seed, berries, grapes, hops, mint, shellfish, tree fruits, and vegetable row crops; beekeepers and users of managed pollinators; operators of small farms in economically disadvantaged areas; Master Gardeners and home gardeners; and professional urban pest managers. Alfalfa seed growers documented increased utilization of IPM techniques. Grape growers had a measurable increase in use of rootstocks and other techniques to manage nematodes and phylloxera. Hop growers are utilizing alternative products and varying pesticide application rates and timing to reduce residues and increase export options. Beekeepers and handlers, including those whose primary language is Spanish, are using scouting and microscopy to help control small hive beetle, nosema, and tracheal mites. Shellfish farmers are integrating mechanical management strategies against burrowing shrimp. Small, disadvantaged farms are producing more scurf-free sweet potatoes and managing cutworm outbreaks using IPM. Ninety new Master Gardeners were trained. A group of urban pest managers were trained in the Entomological Society of America's curriculum for Certified IPM Technician and/or Associate Certified Entomologist at least nine received accreditation.
Wyoming: Wyoming Co-PD Arndt, as the coordinator of the Institute for Managing Annual Grasses Invading Natural Ecosystems (IMAGINE) located at the UWYO's Sheridan Research and Extension Center (SREC), is providing wildfire recovery support. IMAGINE is using previous monitoring data to build models for invasive annual grass vulnerability and sagebrush cover to inform decision making on the region effected by the massive 2024 wildfires in Northeast Wyoming. One model was developed to target monitoring efforts for weed treatments in 2025 and another was developed to inform sagebrush reseeding efforts. Co-PD Arndt also initiated field trials to assess invasive annual grass control and big sagebrush establishment within the fire zones. The trial data will improve post-fire recovery options in the future. In addition, Co-PD Arndt assisted a local invasive annual grass working group in applying for grant funding to treat Ventenata and Medusa head in Northeast Wyoming by providing information gained from research at SREC and the written narrative for two separate applications. The working group was awarded $4.5 million from the Wyoming Wildlife and Natural Resource Trust Fund and $500,000 from US Fish and Wildlife. Term: 2024-2026.
