Non Technical Summary
Arizona is characterized by extremely productive irrigated agricultural lands, unique flora and fauna, extreme and sensitive environments, large urban centers made-up of transplanted people and cultures, and often remote tribal communities. Our diverse stakeholders require information on the safe and effective management of pests, including ways to reduce risks to human health and the environment while sustaining economically viable industry in our state. The Arizona Pest Management Center, formed in response to stakeholders' demands for greater transparency, engagement and relevance in our programs, encompasses the full set of University of Arizona research and Extension resources involved in the implementation of IPM in Arizona.Our Extension IPM programs are organized within the Arizona Pest Management Center, which coordinates programs, communication, planning, stakeholder engagement and IPM team building, through a stakeholder IPM Coordinating Committee that advises the IPM Coordinator (Ellsworth, P.D.), and directs the IPM Program Manager (Fournier, co-PD). Transdisciplinary Leadership Teams for each Priority Area direct activities of Assistants in Extension that synergize program outputs and enhance our capacity to support IPM implementation including by underserved/Tribal end-users. An IPM Assessment Leadership Team develops resources and approaches to measure adoption and economic, environmental, and human health impacts of IPM across all program areas.Through this project, we support adoption of high-impact IPM programs addressing priority stakeholder needs in three EIP Priority Areas: IPM Implementation in Agronomic and Specialty Crops, IPM Implementation in Communities including Housing and Schools, and IPM in Public Health.Our overall goal is to support and advance IPM implementation by end-users in Arizona through coordinated multidisciplinary education and outreach that empowers pest managers to put IPM knowledge into practice. Team supporting objectives are to design, implement, teach, demonstrate and evaluate tailored IPM programs in diverse settings to help clientele reduce economic, environmental, and health risks from pests and pest management practices, addressing Crop Protection and Pest Management focal areas and National IPM Roadmap goals.We systematically measure the learning outcomes and the economic and environmental impacts of our programs. The APMC provides proven support for stakeholder engagement, needs assessment, strategic planning, outreach and evaluation of IPM in all our systems.

Goals / Objectives
Project GoalsOur goal is to increase adoption and effective use of proven IPM tactics by Arizona citizens and professions in diverse environments, thus reducing environmental, human health and economic risks. Across all focus areas, the structure and support of the Arizona Pest Management Center enhances our capacity to develop, implement and evaluate high-impact IPM programs consistent with stakeholder-identified priorities in the following emphasis areas: IPM Implementation in Agronomic and Specialty Crops, IPM Implementation in Communities including Housing and Schools and IPM in Public Health. The goal of our IPM programs is to support and advance IPM implementation by diverse end-users in Arizona through a coordinated systems approach to education and outreach that empowers pest managers to put IPM knowledge into practice. Our programs identify clientele needs, deliver targeted outcomes, and seek to measure reductions in economic, environmental, and health risks from pests and pest management practices in these diverse environments among diverse end-users.ObjectivesOur objectives are consistent across the three Priority Areas in the project:(1) Engaging stakeholders to identify IPM priorities(2) Customize existing or develop new evidence-based solutions through leveraged, mission-focused applied research (< 20% of EIP effort)(3) Promote IPM adoption and implementation with audience-appropriate educational outreach(4) Assess and document IPM adoption and impacts
Project Methods
MethodsThe Arizona Pest Management Center (APMC) was conceived to encompass and enhance the full set of University of Arizona research and Extension resources involved in the implementation of IPM in Arizona. The APMC Director / State IPM Coordinator (program leadership & administrative contact for this grant;Dr. Peter C. Ellsworth) in consultation with the APMC Associate Director / IPM Program Manager (Dr. Al Fournier) and a 20+ member multidisciplinary stakeholder advisory group (the IPM Coordinating Committee) administer the APMC and serve as resources across all program areas. The IPM Coordinator has statewide responsibility for all IPM programs, manages resources, convenes the IPM Coordinating Committee, and submits federal reports. The IPM Program Manager manages the daily APMC activities, including communication and faculty support for needs assessment activities, proposal development and program evaluation.Our proven approach is centered around full-time Assistants or Associates in Extension (AiE; i.e., Extension educators funded up to 50% through EIP) who interact with County Agents, Extension Specialists, other disciplinary faculty and collaborators who provide the full range of IPM expertise to support program development and delivery. Each EIP Priority Area has a dedicated AiE, and an additional AiE coordinates our IPM Assessment Team. Each AiE is managed and supported by a unique Leadership Team of appropriate subject experts.Leadership Teams oversee IPM program development (priority setting, activities, outputs, deliverables & assessment) and guide and manage AiEs to ensure efficient functioning and delivery of IPM programs. AiEs then form operational teams for implementation and deployment of Extension programming. They coordinate team meetings and communications via email and conferencing technologies, and coordinate development of priority outputs as identified by stakeholders and discussed at team meetings. The AiE serves a coordinating function, catalyzing outputs and impacts of each IPM effort. Each Leadership Team Chair sits on the IPM Coordinating Committee, which provides stakeholder input and serves as the advisory body for the APMC. This ensures accountability.Our methods for implementing the objectives of this grant can be generalized across priority areas as consisting of 4 types of activities: stakeholder engagement, program development (including translational research), program delivery through outreach and education, and program evaluation. Stakeholder engagement occurs across all emphasis areas and includes open discussion at meetings, advisory groups and committees, focus groups, participatory research, and informal dialog with stakeholders, as well as through our Crop Pest Losses and Impact Assessment Signature program (described below). Program development includes applied research activities (<20%) engaged in by Specialists and Agents to develop science-based solutions to stakeholder needs. Development of specific program outputs and outreach education plans are facilitated through our IPM Leadership Teams.EffortsOur outreach approach emphasizes use of field demonstrations; stakeholder-engaged translational research projects; and delivery of short, effective and graphically rich publications, presentations and advisories. We maintain constant contact with stakeholders via IPM Newsletters, email lists and social networking. Program delivery occurs through workshops, field days, demonstrations, cooperative extension meetings, educational presentations, websites, online videos, smart phone updates, radio broadcasts, newspaper articles, blog entries, newsletters, trade publications, extension publications, reports, stakeholder dialog sessions, needs assessments, crop pest losses surveys, informal discussion groups, one-on-one consultations, scientific publications, presentations and symposia, short courses, database development to track outcomes.EvaluationThe APMC has demonstrated a high capacity and history of documenting outcomes and impacts of Arizona IPM. Assessment is fully integrated into program planning for all teams, and is supported by a dedicated IPM Assessment Team. Dr. Fournier (Co- PD) with AiE Wayne Dixon develops tools, data and approaches to assess IPM adoption, outcomes and impacts across all program areas. Fournier, who has expertise in program evaluation methods, advises and supports all teams to develop effective evaluation plans and instruments. Milestones and indicators of success we measure include advances in IPM knowledge and attitudes, adoption of new IPM tactics and reduced-risk approaches, reductions in pesticide use and associated risks, and environmental and economic outcomes.Methods are customized to each program and target audience, and specific methods for each Priority Area are listed in the Expected Outcomes section of this document. Changes in knowledge, attitudes and skills are often assessed in live meetings using audience response technology to implement self-assessments or pre-then-post questionnaires. We also use online survey tools to collect information more broadly across the state for specific target audiences, including changes in knowledge and changes in practice (e.g., adoption of IPM). An example is online surveys of participants in Vegetable IPM programs, which measured changes in knowledge, adoption of reduced-risk practices, and economic impacts. Surveys can be implemented live or via Zoom meetings or participation solicited through team email newsletters. Follow up surveys to measure adoption can be sent to a subset of program participants who agree to be contacted in the future.In addition, we have developed the following unique data resources and approaches to measure the adoption and impacts of IPM, and the reduction of risk as outlined in the IPM Roadmap.1.The APMC Pesticide Use Databasecontains >30 years of Arizona agricultural pesticide use reports submitted by growers for all custom applications. These data allow us to measure changes in pesticide use for all Arizona crops.2. Crop Pest Losses and Impact Assessment surveysdocument real-world impacts of key insect, weed and disease pests and their management on crop yields and grower economic outcomes. We conduct annual stakeholder interactions to facilitate impact assessments in cotton and lettuce. Through a Western IPM Center Signature Program, our approach has been adapted to conduct assessments in several Pacific Northwest crops, in partnership with Oregon State University. These surveys help document economic risks to growers from pests and the costs associated with their management.3. Measuring Reductions in Pesticide Risk. We recently used the Pesticide Risk Tool (https://pesticiderisk.org) along with EPA pesticide risk assessments to identify environmental and human health risks of insecticides used in US cotton production, and pesticide use data to show that these chemistries are used on <1% of Arizona cotton acres.

Outputs
Target Audience:Professional, licensed Pest Control Advisors (PCAs), growers, agricultural industry representatives, pesticide applicators, State and Federal agencies and pesticide regulators, nursery and landscape industry, associations, commodity groups, Master Gardeners, homeowners, public school staff, non-governmental organizations, urban pest management professionals, public health professionals, food safety professionals, representatives from numerous tribes and tribal organizations, racial and ethnic minorities that work in agricultural and urban sectors. Changes/Problems: Nothing Reported What opportunities for training and professional development has the project provided?This project provided significant professional development opportunities for two graduate students within IPM Implementation in Agronomic and Specialty Crops priority area. Both are employed as Assistants / Associates in Extension in our programs. Victoria, who is starting a Masters in Entomology under Dr. Peter Ellsworth, works primarily with our agronomic crops team and Macey, who recently began her Ph.D. also under Peter Ellsworth works with our specialty crops team. They are gaining valuable experience conducting applied research, developing outreach materials, coordinating training events, and presenting to and interacting with growers and pest managers. They will soon be writing and publishing scientific papers. In addition, Entomology Extension Specialist Dr. Wilfred Calvin employed four undergraduate volunteer student interns last year, two of which are now employed in his lab. His program focuses on IPM in organic production systems. These student's projects are all highly leveraged through other grants, but our growers and pest control advisors will greatly benefit from their work through our ongoing Extension and outreach efforts. We also benefited this project term from four undergraduate student interns, two of them tribal members, in the Public Health IPM program. Interns helped Dr. Shujuan Li develop Extension materials and publications. How have the results been disseminated to communities of interest?We use diverse tactics to reach target audiences, from traditional Extension methods to webinars and remote delivery, websites, etc. We have increased our emphasis on short Extension publications, "IPM Shorts," and are developing more YouTube videos and social media posts. Some of our online and hybrid meetings are recorded and presentations made available to broader audiences after the event. Extension collaborations with tribal environmental health professionals provided improved distribution of IPM information (particularly public-health related) to members of several Arizona-based Indian tribes. Information was collaboratively modified to better communicate with these audiences, and distributed through tribal channels, including radio programs and Facebook pages. We have seen an increased acceptance of remote delivery across all programs but have returned to frequent face-to-face interactions while maintaining many remote options. We develop training presentations which are available online for continuing education credits (CEUs) through industry partnerships. Many of these materials receive a very high number of views and help train urban and agricultural pest managers. Methods of program delivery included workshops (online & face to face), field days, Cooperative Extension meetings, educational presentations, websites, webinars, Zoom conferences and presentations, smart phone updates, newspaper articles, videos, radio broadcasts, IPM guidelines, newsletters, trade publications, Extension publications, reports, stakeholder dialog sessions, needs assessments, crop pest losses surveys, informal discussion groups, one-on-one consultations, scientific publications, presentations and symposia.

Impacts
What was accomplished under these goals? RELEVANCE Pests threaten the economic and environmental sustainability of Arizona's agriculture, communities, and public health. Growers, schools and tribal partners require research-based pest solutions that reduce chemical risks and protect people, property, and ecosystems. Our work addresses real-world problems like yield-robbing insect pests (Lygus and whiteflies) of cotton, pesticide-resistant pests, insects and weeds in organic crops, insect and microbial contaminants in our fresh leafy greens and other fresh vegetables, rodents in schools, and ticks and other disease-transmitting pests on tribal lands and in other communities in Arizona. RESPONSE Agricultural IPM:We worked with stakeholders to identify Integrated Pest Management (IPM) needs and conducted leveraged applied research in cotton, lettuce and many other crops. We developed and promoted advanced IPM solutions through more than 25 in-person and virtual events, reaching 1,100 people and delivering over 90 continuing education credits (AZ, CA, CCA). We published 15 new Extension publications and sustained our bi-weekly Vegetable IPM newsletter and smartphone alerts with over 1,000 subscribers. Community IPM:Our team hosted 3 statewide events and the 8th annual School IPM Conferences, reaching over 400 landscape and facility managers with 65 CEUs issued. We responded to 300+ pest management queries and produced 6 IPM newsletters addressing rodents, scorpions, termites, and pesticide notifications, reaching 1400+ subscribers. We collaborated nationally to reduce duplication and improve school IPM education. Public Health IPM: With 7 out of the 16 Arizona tribes, we conducted needs assessments, field research, and educational outreach focused on ticks, food safety, and community health. We held 13 workshops on tribal lands, trained 976 pesticide applicators in 13 events, and reached over 2,000 pest management professionals nationwide through distributed education platforms. We developed customized tick management and rabies prevention clinics, vaccinated 150+ dogs, and distributed tick collars. OUTCOMES Agricultural Crops IPM 84% of Arizona pest managers surveyed are familiar with predator thresholds which allow growers to defer a spray when key beneficial predators are present at sufficient levels; 69% have usedthem, helping reduce insecticide sprays to just 1.5 per acre. 40% of fields went unsprayed in 2024. ThryvOn cotton, genetically engineered to resist injury from yield-limiting Lygus bugs, grown on 29,181 acres in 2024, double the amount of 2023, was sprayed 50% less than standard cotton, saving $800,000 in insecticide costs. Use of highly toxic insecticides dropped over 93% in cotton since the early 1990s. 90% of cotton insecticide use is with materials safe to beneficial predators and pollinators. In lettuce, 60% of insecticide sprays now use selective products that support ecosystem health. Arizona cotton achieved a 1000X increase in eco-efficiency, a measure of safety, from 1990 to 2024. Cotton IPM has saved growers $700M and prevented 40M lbs. of insecticides from entering the environment since 1996. 87% of Vegetable IPM newsletter subscribers used our pest advice; 89% reduced toxic pesticide use; 89% reported improved economic returns saving $69-$189 per acre. Community IPM 99% of IPM conference attendees said they planned to adopt at least one new IPM strategy. We supported agave growers with new grease mite research and identification tools in collaboration with USDA. Public Health IPM After 13 workshops, IPM knowledge rose by 79%; food safety understanding rose by 61%; 64% adopted new practices. 100% of attendees at our Vertebrate/Rodent Academy (over 50 pest management professionals) committed to changing their pest management practices. Our newsletters and online modules expanded reach to 2,800+ across the U.S., empowering professionals and the public with actionable information. Our respectful, sustained engagement with tribal communities has shifted community dynamics, fostering deeper trust and collaboration, now reaching 16 of Arizona's 22 tribes.This trust, earned through consistent presence, cultural sensitivity, and delivery of tangible results, has led to increased participation in IPM programs, expanded our tribal networks by 15%, and opened doors for co-developing community-driven pest management and food safety initiatives. These relationships are the foundation for long-term capacity building and self-determined public health improvements in tribal nations. IMPACT Our IPM programs address real pest problems with stakeholder-engaged scientific research and deliver stunning outcomes. We empower farmers, school managers, tribal communities, turf and landscape professionals, health and environmental health professionals and homeowners to solve pest problems while protecting people and the environment. For example, our agricultural IPM programs have resulted in fewer pests, fewer sprays, and benefits to the environment including support for pollinators and predator species that support biological control, along with enormous savings to growers. Extension-led science and outreach have reduced chemical use, improved economic returns, and supported healthier schools, homes, and farms. These efforts improve public health, food safety, and ecosystem resilience across Arizona and beyond.
