The mission of the Arizona Pest Management Center (APMC) is to support College of Agriculture and Life Sciences (CALS) faculty in their efforts to develop and deliver outstanding Integrated Pest Management (IPM) programs that address the needs of Arizona’s citizens. This includes IPM programs serving agriculture, urban communities and natural areas.

  • The University of Arizona 2022 Cotton Variety Testing Program - Trial Results

    Norton, Randy; University of Arizona, Extension Agronomist (College of Agriculture, Life & Veterinary Sciences & Cooperative Extension, University of Arizona (Tucson, AZ), 2023-02)
    Variety selection is one of the most important decisions a grower will make contributing to the success of a cotton crop. It is critical, that a grower have as much information as possible in order to make an informed decision regarding variety selection. In an effort to help supply reliable variety performance information, the University of Arizona conducts a statewide cotton variety testing program. The 2022 cotton season variety trials were conducted in 3 locations across Arizona including Yuma, Maricopa, and Safford. This testing program is called the University of Arizona Upland Cotton Advanced Strains Testing Program.
  • Highly Hazardous Pesticide Phase-Out for US Cotton Growers: Alternatives, Risks, and Opportunities

    Wynne, Karen; Fournier, Alfred; Ellsworth, Peter C.; Better Cotton Initiative; University of Arizona (2023-01)
    As part of its focus on making cotton production better for the environment and the people who produce it, Better Cotton is committed to reducing the hazardous impacts of pesticide use on human health and the environment. Better Cotton supports farmers to prioritizeIPM practices, phase out Highly Hazardous Pesticides (HHPs), and minimize the negative impacts of pesticides that continue to be used. We reviewed seven of the most acutely toxic substances that have been used by Better Cotton growers in the US to understand risks to human health and the environment, chemical and cultural alternatives, mitigation measures, and tradeoffs and limitations. The active ingredients are abamectin, aldicarb, bifenthrin, dicrotophos, lambda-cyhalothrin, oxamyl, and phorate. The information reviewed includes pesticide use reports from California and Arizona, interviews with key regional experts, EPA risk assessment documents, the IPM Institute’s Pesticide Risk Tool, and other online resources. HHPs are defined by the World Health Organization and UN Food and Agriculture Organization; Better Cotton reviews and revises its list annually to reflect updates to product information.
  • Highly Hazardous Pesticide Phase-Out for US Cotton Growers: Alternatives, Risks, and Opportunities

    Ellsworth, Peter C.; Fournier, Alfred; University of Arizona, Department of Entomology, Maricopa Agricultural Center (2022-09-30)
    The global community has identified sets of highly hazardous pesticides, of which at least 16 are in use by US cotton growers, four of those are prohibited and others are targeted by Better Cotton for phase-out. While there have been attempts to unify this information into a single list, agencies and organizations have maintained their own versions of highly hazardous pesticides. This report examines current use patterns, utility and efficacy; alternative pest management technologies and techniques including their efficacy, limitations and trade-offs; specific environmental and human health hazards, and translation to risks in the US cotton system, and efficacy and limitations of mitigations. We also present barriers to phase-out for each insecticide and the ramifications this might have for Better Cotton’s US cotton production. Lastly, we identify opportunities for supporting growers during this period of transition, including with coordinated education and outreach.
  • Making Whitefly & Predator Counts

    Vandervoet, Timothy F.; Ellsworth, Peter C.; Brown, Lydia; Fournier, Alfred; Naranjo, Steven E.; New Zealand Plant and Food Research; University of Arizona; USDA-ARS (College of Agriculture and Life Sciences, University of Arizona (Tucson, AZ), 2019-01 r)
    Guidelines for sampling whiteflies and identifying predators critical in their management. Includes predator-prey tables that provide guidelines that aid in management decisions of whiteflies.
  • Predator “Thresholds”

    Ellsworth, Peter C.; Pier, Naomi; Fournier, Alfred; Naranjo, Steven E.; Vandervoet, Timothy F.; University of Arizona; USDA-ARS; New Zealand Plant and Food Research (College of Agriculture and Life Sciences, University of Arizona (Tucson, AZ), 2019-01 r)
    Natural enemy conservation is central to pest avoidance in cotton. The benefit of predators for controlling whiteflies should not be overlooked. Today’s growers can use selective technologies that conserve predators, which play a critical (& free) role in controlling whiteflies. We don’t normally think of predators as having “thresholds”, but new research identifies critical levels of predators that impact economic spray decisions for whiteflies.
  • In 7 Minutes or Less!

    Ellsworth, Peter C; Brown, Lydia; Castro, Gilberto; Naranjo, Steven E.
    In 7 minutes or less and just 7 steps, you can determine the size and structure of Bemisia tabaci populations in a cotton field. With this information, more precise and appropriate control decisions can be made.
  • Cotton Insecticide Use Guide: Knowing and Balancing Risks

    Bordini, Isadora; Fournier, A.; Naranjo, Steven E.; Pier, Naomi; Ellsworth, Peter C; University of Arizona; USDA-ARS (College of Agriculture and Life Sciences, University of Arizona (Tucson, AZ), 2020-07-11)
    Many factors must be considered when choosing an insecticide, such as cost, efficacy, risk of resistance, and safety to non-target organisms. This Cotton Insecticide Use Guide summarizes the diverse risks of insecticides used to control three pests, helping you make well informed pest management decisions
  • Integrating Chemical & Biological Control in Cotton

    Ellsworth, Peter C; Bordini, Isadora; Pier, Naomi; Naranjo, Steven E.; University of Arizona, Department of Entomology & Cooperative Extension (College of Agriculture and Life Sciences, University of Arizona (Tucson, AZ), 2022-07-15)
    Biological control works when chemical controls are carefully selected so that key predator groups are conserved. Big-eyed bugs, Collops beetles, crab spiders, lacewing larvae, minute pirate bugs and Drapetis flies are the key predators in the cotton system. They can effectively hold whiteflies in check when their numbers are high enough. Includes updated whitefly predator threshold tables.
  • Utilizando los Predadores en Algodón - FMC22

  • ThryvOn™ Cotton, Frequently Asked Questions

    Ellsworth, Peter C.; Bordini, Isadora; Pier, Naomi; Entomology / Maricopa Agricultural Center (The University of Arizona (Tucson, AZ), 2021-06-09)
    ThryvOn™ cotton is genetically engineered to resist injury by Frankliniella thrips and Lygus bugs. ThryvOn cotton is a major addition to the cotton IPM strategy. It will provide a new mode of action for diminishing the impacts of thrips and Lygus in cotton. This IPM Short should answer frequently asked questions of stakeholders and help growers and pest control advisors establish and discuss their expectations.
