ABOUT THE COLLECTION
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.

EPA’s Mitigation Menu to Protect Endangered SpeciesThe Environmental Protection Agency (EPA) must ensure that the use of a pesticide will not jeopardize federally listed threatened or endangered species, nor damage their critical habitats. For certain pesticides where runoff or soil erosion may pose threats to listed species, EPA may require users to ensure that protections are in place that will limit the potential for pesticide exposure. This is done through a system of “mitigation points” or “credits” that are obtained by users through adopting mitigation practices or documenting existing conditions that reduce risks of runoff and erosion. If points are needed to apply a pesticide, this requirement will be listed on the pesticide label and/or on an Endangered Species Bulletin. Arizona has many common field conditions, including a low to very low potential for runoff, that should make it easy for most growers in most situations to comply with mitigation requirements. This piece outlines situations where fields may be completely exempt from point requirements and identifies the most common conditions and practices in Arizona agriculture that can earn mitigation relief points. A link is provided to EPA’s Mitigation Menu website where definitions and additional mitigation practices are listed.

Endangered Species Protection Bulletins Part 2: Understanding Pesticide Use Limitation AreasThe Environmental Protection Agency (EPA) must ensure that the use of a pesticide will not jeopardize federally listed threatened or endangered species, nor damage their critical habitats. When required on a pesticide label, online Endangered Species Bulletins provide geographic-specific protections for listed species while allowing full labeled use of the pesticide in other areas. They are obtained through EPA’s Bulletins Live! Two, an interactive web-based app. An increasing number of pesticide products, though not all, require users to view and download Endangered Species Bulletins prior to making an application. Part 2 in this series explains the nuances of Pesticide Use Limitation Areas (PULAs) on Bulletins Live! Two using an example of a grower with fields both within and outside of a PULA. It clarifies differences in how to print a bulletin when a PULA is present or absent in the map view. it also highlights the main elements presented in an Endangered Species Bulletin.

Endangered Species Protection Bulletins Part 1: What are they and when do you need them?The Environmental Protection Agency (EPA) must ensure that the use of a pesticide will not jeopardize federally listed threatened or endangered species, nor damage their critical habitats. When required on a pesticide label, online Endangered Species Bulletins provide geographic-specific protections for listed species while allowing full labeled use of the pesticide in other areas. They are obtained through EPA’s Bulletins Live! Two, an interactive web-based app. An increasing number of pesticide products, though not all, require users to view and download Endangered Species Bulletins prior to making an application. Part 1 in this series explains how to determine when an Endangered Species Bulletin is required, where and how to obtain a bulletin, and what type of information is provided.

The University of Arizona 2022 Cotton Variety Testing Program - Trial ResultsVariety 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 OpportunitiesAs 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 OpportunitiesThe 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.
