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.

Performance Evaluation of Nitrate-Nitrogen Sensing Technologies in Organic and Conventional Iceberg Lettuce Systems under Subsurface Drip IrrigationEfficient nitrogen management in arid agricultural regions such as Yuma County, Arizona requires close coordination of irrigation and fertilizer applications because water movement within the soil profile directly affects nitrogen dynamics and plant uptake efficiency. This study evaluated near-real-time nitrate-N sensing technology under organic and conventional iceberg lettuce (Lactuca sativa) production systems using subsurface drip irrigation. Field trials were conducted during the Fall 2024–Spring 2025 growing season at the University of Arizona Yuma Agricultural Center on a Gila silt loam soil.

How to Identify Eggs and Early Instar Larvae of Beet Armyworm, Diamondback Moth, and Cabbage LooperThis article, published in the Vegetable IPM Newsletter (Vol. 16, No. 23), provides diagnostic features to distinguish eggs and early instar larvae of beet armyworm, diamondback moth, and cabbage looper. It highlights key differences in color, shape, clustering, and larval behavior to improve field identification and management of these common vegetable pests.

Guidelines for Asian Citrus Psyllid and Citrus Greening Disease Management in Commercial Citrus ProductionCitrus growers are essential to protecting Arizona’s citrus industry from the spread of HLB. Consistent monitoring for ACP and early disease symptoms, combined with timely and effective management practices, can significantly reduce the risk of infection. Reporting infected trees to the appropriate authorities and following recommended control strategies can help prevent the spread of both the vector and the disease. Cooperation of growers and pest control advisors is vital; HLB management is most successful when efforts are coordinated across regions. By staying informed and proactive, we can help preserve the health, productivity, and future of citrus groves across the state. Your actions make a lasting impact.

2024-2025 Growth, Physiology, Yield, and Quality Evaluation of Small Grain Varieties in Central ArizonaChoosing an appropriate crop variety is critical for farmers, especially in Arizona’s small-grain production systems. There exists considerable variation among small grain varieties, with each displaying distinct levels of adaptability and performance traits that ultimately affect the profitability of farming ventures. The performance of varieties can fluctuate significantly from year to year, highlighting the importance of conducting evaluations across multiple site-years to assess a variety's yield potential accurately.

Building the Future of Law Libraries: Artificial Intelligence, Opportunities, and AdvancementThe Future of Law Libraries initiative convened six regional roundtables on Artificial Intelligence & the Future of Law Libraries with experts from academic, court, firm, and government law libraries, as well as allied professions, using scenario-building methodology to examine how AI is reshaping legal education, work, and systems and what law libraries must do to lead that change. The common message: legal information professionals must take an active, coordinated role in AI policy, training, and infrastructure or risk being sidelined as legal information vendors and non-library actors set the agenda. This white paper distills convergent themes and proposes collaborative directions. It explores three recommendations that sprang from the roundtables: 1) create a centralized AI organization, 2) develop tiered training for legal information professionals, and 3) establish a shared knowledge hub. If we are successful in this next stage, we will have coordinated advocacy and standards, a workforce with more advanced skills, and an open, authoritative, dynamic, centralized repository. We will be convening teams to push these recommendations forward and we provide a link in the Call to Action section for our colleagues to join this effort.

No Department, No Enforcement: Title IX After the Collapse of the Department of EducationThe structural foundations of Title IX enforcement are undergoing a profound transformation. President Trump’s 2025 executive order initiating the closure of the Department of Education, combined with the vacatur of the 2024 Title IX regulations and the Supreme Court’s elimination of Chevron deference in Loper Bright, has fundamentally dismantled the administrative framework that long anchored Title IX protections. Unlike prior regulatory shifts, these developments raise the question of whether meaningful federal enforcement will continue to exist at all. As administrative structures recede, courts will assume a much greater role in defining Title IX’s scope and enforceability, despite their institutional limitations. This Article argues that the resulting shift will narrow substantive protections, restrict access to justice, and produce fragmented interpretations of Title IX across jurisdictions. It examines the statute’s original design as an evolving administrative framework, explores the barriers marginalized students will face under a litigation-driven model, and explains why courts are ill-equipped to provide consistent, forward-looking guidance. This Article concludes by considering potential legislative reforms to restore national coordination in Title IX enforcement, drawing lessons from Congress’s intervention following Grove City College v. Bell.
