(Beyond Pesticides, February 25, 2025) A literature review of over 90 scientific articles in Agriculture documents microplasticsâ (MPs) increase in the bioavailability, persistence, and toxicity of pesticides used in agriculture. The interactions between MPs and pesticides enhance the threat of pesticide exposure to nontarget organisms, perpetuates the cycle of toxic chemical use, and decreases soil health that is vital for productivity. âThe increasing presence of MPs in agricultural ecosystems has raised concerns about their impact on pesticide bioavailability, efficacy, and environmental behavior,â says study author Kuok Ho Daniel Tang, PhD, a global professor in the Department of Environmental Science at the University of Arizona. He continues, âThese synthetic particles interact with pesticides through adsorption and desorption processes, altering their distribution, persistence, toxicity, and uptake by plants and other organisms.â Microplastics in the Environment As Beyond Pesticides has previously reported, microplastics are ubiquitous and threaten not only human health but all wildlife in both aquatic and terrestrial ecosystems. The universal distribution of plastics means that they cannot be avoided. Humans and other organisms take up plastics in the form of microparticles and nanoparticles by inhalation, ingestion, and skin contact every day. Microplastics are about the width of a human hair; nanoplastics […]

(Beyond Pesticides, February 19, 2025) In Global Ecology and Conservation, a study of bat species in organic desert date palm plantations highlights the invaluable ecosystem services these beneficial organisms provide. âBats are crucial in suppressing pest arthropods in agroecosystems, contributing vitally to sustainable agriculture,â the study authors share, which makes supporting bat populations important not just for biodiversity but to help enhance their roles in pest management. Â Â There are various studies connecting organic agriculture and the value it provides for bats and their ecosystem services. (See studies here, here, and here.) While many studies also recognize bat species threatened by pesticides, habitat loss, and climate change, “the importance of bats in agriculture in extreme environments, such as deserts, has received far less attention,â the researchers state. (See previous coverage on pesticide exposure and bats here and here.) They continue, âDate palm plantations represent one of the few productive systems in hyper-arid regions,â noting the studyâs novel design. The date palm, primarily grown throughout the Middle East and North Africa, is one of the earliest domesticated fruit trees. âThe date palm cultivationâs monocultural nature increases susceptibility to pest infestations due to limited plant diversity, involving 112 mite and insect species.â […]

(Beyond Pesticides, January 30, 2025) A research article in Biology Letters, published by The Royal Society, finds that the neonicotinoid insecticide imidacloprid disrupts survival and reproductive patterns in Bombus impatiens bumblebees. The study adds to the wide body of science highlighting how exposure to pesticides âcan result in immediate mortality or cause long-term detrimental effects on pollinators‘ health, lifespan and reproductive success,â the authors state. The researchers performed two experiments to assess the effects of various concentrations of imidacloprid, one of which focuses on bees during diapause, a period of dormancy. âWild bees, which provide the majority of pollination services worldwide, undergo an annual life cycle that includes a winter diapause, that can span over 75% of their life cycle and during which their metabolism, growth and development are halted,â the authors note. They continue: âThe time spent in diapause can have lasting effects on pollinator fitness and their ability to establish nests or colonies in the following spring. This period is especially critical for social bee colonies, which are founded by a single queen after diapause and play a vital role in large-scale pollination.â Exposure to pesticides during diapause can occur while bee species overwinter in contaminated soils.

(Beyond Pesticides, January 27, 2025) A public comment period ends today, January 27, 2025, on the U.S. Fish and Wildlife Service’s (FWS) proposed critical habitat rule to protect the rusty patched bumble bee under the Endangered Species Act (ESA). This proposal is responsive to the agency’s 2024 stipulated settlement agreement resulting from years of advocacy and government review and a 2023 court order (NRDC et al. v. U.S. Fish and Wildlife Service, et al.). The proposal follows a 2017 determination by the agency that lists the bumble bee as an endangered species. (See previous Daily News here, here, here, here, and here.) >> Tell the U.S. Fish and Wildlife Service to fully protect the endangered rusty patched bumble bee by finalizing its proposed critical habitat rule with strengthening provisions. The FWS proposal grows out of a species status assessment (SSA) conducted by â15 scientists with expertise in bumble bee biology, habitat management, and stressors (factors negatively affecting the species).â University of Illinois Urbana-Champaign insect ecologist Jason Robinson, PhD concludes in his paper, âProject-specific bumble bee habitat quality assessment,â âAs the first social insect listed under the ESA, the listing of RPBB has required new methods for biological assessment. This species has a complex life cycle requiring a mosaic of different habitat types, […]

(Beyond Pesticides, January 7, 2025)Â A report, released in December 2024 from the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES), confronts the problem of âsiloingâ environmental elementsâfood, health, water, biodiversity and climate changeâwhen they instead intersect at a nexus from which each element affects all the others. The problem is essentially that all the elements are part of the same crisis, yet actions to address issues within eachâand, importantly, to resist addressing themâare dealt with in isolation. A proper perspective, gleaned from the report, is to view each element from the center where all parts meet, thus addressing the issues in coordination. According to the IPBES report, â[F]ragmented governance of biodiversity, water, food, health and climate change with different institutions and actors often working on disconnected and siloed policy agendas, resulting in conflicting objectives and duplication of efforts.â The IPBES is an independent body analogous to the Intergovernmental Panel on Climate Change (IPCC) but structured similarly and in close contact with the United Nations (UN). The new report comes at the behest of IPBESâs 147 member countriesâ75 percent of the UNâs membershipâto address the interconnections among the five global crises. The report strongly demonstrates that a holistic, globe-spanning frame […]

(Beyond Pesticides, January 6, 2025) With the incoming U.S. president promising the âmost aggressive regulatory reductionâ ever seen in the countryâs history, attention shifts to local and state governmentsâ responsibility to protect health and the environment. While the reliance on local governments to fill the gaps left by deficient federal action is not new, the U.S. system of federalism has historically and constitutionally required a sharing of powers from local to state to federal, with a reliance on agencies like the U.S. Environmental Protection Agency (EPA) to establish a basic level of protections. While the role of local and state governments has been critical to ensuring environmental and public health protection when scientific findings have shown federal action to be inadequate, the new administration has outlined a course that suggests an increasingly important role for local and state governments. As Beyond Pesticides has reported, âMr. Trump, who has called climate change a âhoax,â has targeted âevery oneâ of Mr. Bidenâs policies designed to transition the United States away from fossil fuels,â according to The New York Times. This is happening as the country and world face serious catastrophic threats of ongoing and escalating health, biodiversity, and climate crises. In this context, […]

(Beyond Pesticides, January 3, 2025) Pesticides that are sprayed and become airborne significantly disrupt ecological balances and affect nontarget species that are crucial for maintaining biodiversity, according to an article in Environmental Pollution. In this review of studies throughout countries in North and South America, Europe, and Asia, among others, researchers from Germany, Norway, the United Kingdom, and Poland reinforce the science about pesticidesâ direct effect on species and the cascading effects of pesticide drift through various trophic levels within food webs that lead to overall devasting population effects. This study âaddresses the interconnectedness of these impacts and illustrates the complex threats that pesticide drift poses to biodiversity across multiple ecosystems,â the researchers state. They continue: âImpacts include reduced reproductive rates, changes in growth, development, and/or behavior, modification of diversity or community organization, disruption of food webs, and declines of important species. Pesticides disrupt the delicate balance between species that define a functioning ecosystem. Impacts can be local, transnational, or even continental.â Pesticide drift threatens beneficial species and subsequently the entire agricultural system. The process of pesticide drift, âin which up to 25% of applied pesticides are carried by air currents, can transport chemicals over hundreds or even thousands of […]

(Beyond Pesticides, December 24, 2024 – January 1, 2025) We wish you a healthy and happy holiday season! The health and environmental challenges that we face as families and communities across the nation and worldwide require us to stay engaged. The stark reality of the challenges ahead energizes us at Beyond Pesticides to strengthen our programânow, more than ever!  And, we trust that you, like us, want to push forward for a livable future. In this context, please see our annual report and summary on the important work that we are doing, and please consider a contribution to Beyond Pesticides during this holiday season. While the threats of health, biodiversity, and climate crises grow exponentially, the solutions we have advocated for decades are now within reach. We know how to produce food and manage land without petrochemical pesticides and fertilizers, as organic food is widely available. Beautiful parks, playing fields, and schoolyards do not require toxic chemical use. At the same time, the regulatory system underperforms, as existential health and environmental problems escalate.  And, we know that individual steps that we take to stay healthy, as important as they are, cannot protect us and the natural world, on which […]

(Beyond Pesticides, December 23, 2024)Â As the U.S. Fish and Wildlife Services (FWS) proposes to list the Monarch butterfly as a threatened species under the Endangered Species Act, a look at the factors contributing to the butterflyâs catastrophic decline includes a stunning failure of the U.S. Environmental Protection Agencyâs (EPA) regulation of pesticides to protect biodiversity and the ecosystems necessary to its survival. While there are many factors affecting the survival of Monarchs, EPAâs Office of Pesticide Programs (OPP) has allowed pesticide use to continue unabated, with only rhetorical attention to the problem. Meanwhile, the science shows a range of pesticide effects associated with insecticides and herbicides. A study published in PLOS One in June identifies insecticides as the primary driver in butterflyâs decline, as EPA points, almost exclusively to herbicide use and the destruction of Monarchsâ food source, milkweed habitat. While two or several factors can be true at the same time, EPA has failed to consider the confluence of factors, including the impacts of climate, as rising temperatures are exacerbated by the production and use of petrochemical pesticides. FWS is stepping in at a critical time with looming biodiversity collapse and in the absence of EPA taking the reins […]

Image: Art Page submission from Carol Moyer, “Monarch Butterfly Sideways with Closed Wings.“ (Beyond Pesticides, December 20, 2024) On December 12, the U.S. Fish and Wildlife Service (FWS) opened a public comment period on its proposal to list the monarch butterfly (Danaus plexippus) as a threatened species and to designate critical habitats for the species under the Endangered Species Act of 1973. Under the proposal, the designated habitats would span approximately 4,395 acres throughout overwintering sites in coastal California. The public comment period will be open until March 12, 2025. These suggested protections call attention to the role of chemical-intensive agriculture in affecting populations of pollinators and other beneficial organisms. George Kimbrell, legal director at the Center for Food Safety, shares in a press release that the âmonarch listing decision is a landmark victory 10 years in the making. It is also a damning precedent, revealing the driving role of pesticides and industrial agriculture in the ongoing extinction crisis… But the job isnât done: Monarchs still face an onslaught of pesticides. The Service must do what science and the law require and promptly finalize protection for monarchs.â In the docket, FWS states, âUnder the Act, a species warrants listing if […]

(Beyond Pesticides, December 13, 2024) In October, the U.S. Environmental Protection Agency (EPA) approved the registration applications of BASF Corporation and Mitsui Chemicals Crop & Life Solutions, Inc. for the use of different formulations of the L-isomer of glufosinate (also known as âL-glufosinateâ and âglufosinate-Pâ) as new active herbicidal ingredients. This decision marks one of the first times that EPA has employed its new Herbicide  Strategy Framework to determine the level of mitigation necessary to protect listed species and critical habitat under the Endangered Species Act (ESA). Glufosinate is an organophosphate, with known neurotoxic, reproductive/developmental effects, toxic to aquatic life, and mobile in soils (see Beyond Pesticides Gateway). Scientists have found that formulated glufosinate is generally more toxic to aquatic and terrestrial animals than the technical grade active ingredient. Manufacturers are introducing newer glufosinate products as alternatives for glyphosate-based herbicides, like Bayer/Monsantoâs âRoundupâ and dicamba. The Center for Biological Diversity notes in comments submitted to EPA on this decision, âL-glufosinate has the potential to be used on tens of millions acres of land every year given the crops EPA has proposed to register it on. The scale of potential use is far above most new active ingredients.â This first significant application […]

(Beyond Pesticides, December 12, 2024) A literature review of 161 articles in Discover Toxicology finds that pesticides with different mechanisms of action cause memory and learning impairments. These effects are noted in nontarget species including humans. Pesticide â[e]xposure during development, as well as chronic environmental and occupational exposure, can contribute to decreased cognitive performance,â the researchers say. With a focus on organophosphate pesticides, synthetic pyrethroids, and neonicotinoid insecticides, the authors highlight neurological impacts. Both learning and memory are crucial for the survival of many species. “Considering the importance of learning and memory for human and non-human animal behavior and the growing association between pesticide exposure and cognitive impairment, the aim of this review was to describe the studies showing the impact of pesticide exposure on memory and learning abilities in nontarget species, providing evidence of the impact of pesticides in central nervous system function,â the researchers state. The 161 articles included in the review were identified through database searches in PubMed/Medline and Scielo. The authors note, âInclusion criteria for article selection included all articles published in English between 2015 and 2024 containing original studies in animals or humans with single or multiple pesticides exposure.â The articles consist of 132 preclinical […]

(Beyond Pesticides, December 3, 2024) In an article in Science, Sabrina Rondeau, PhD reviews her research from 2022-2024 showcasing species of ground-nesting bees, often found in crop fields, that are highly vulnerable to soil pesticide residues and subsequently suffer population declines. Dr. Rondeau, a postdoctoral fellow in the Department of Biology at the University of Ottawa, points to regulatory deficiencies, specifically in environmental risk assessments (ERAs), and the detrimental effects of pesticides on pollinators that threaten food security and biodiversity. âModern intensive agriculture faces a critical paradox: The very pesticides designed to protect our crops endanger essential pollinators that sustain their productivity,â Dr. Rondeau says in the article. Her research (see here, here, here, here, here, and here) identifies important gaps overlooked in current assessments and regulations for bee species, including the common eastern bumble bee (Bombus impatiens) and the hoary squash bee (Xenoglossa pruinosa). Bumble bee queens in temperate climates hibernate for 6-9 months in the soil, while the hoary squash bee is a solitary ground-nesting species. Reference additional Daily News coverage on ground-nesting bees here and here. ââOur findings show that over 70% of wild bee species, which are crucial for pollinating our food crops, face significant risks […]

(Beyond Pesticides, November 6, 2024) An analysis in the International Journal of Research Publication and Reviews emphasizes the role of biodiversity in agriculture, adding to a wide body of science on its importance. The authors, from Western Illinois University in the United States and Rome Business School in Italy, find that biodiversity supports critical ecosystems and organisms needed for sustainable food production. Through literature reviews and case studies, the interconnectedness of agriculture with plant and animal diversity, beneficial insects, soil health, and climate change is highlighted, as well as the need to manage land organically to support biodiversity. Plant and Animal Diversity As the researchers note, âA diverse agricultural system can better absorb shocks and maintain productivity, ensuring food security in the face of uncertainty.â A wide range of species present within ecosystems protects from changing environmental conditions and improves resilience. When farmers use monocultures for their crops, this leads to reduced ecosystem services from beneficial insects and increased vulnerability to pests and diseases. âBy contrast, diverse cropping systems can enhance resilience, providing a buffer against environmental changes and fostering sustainable food production,â the authors say. Research shows that higher plant diversity disrupts pest life cycles and promotes beneficial insects, […]

(Beyond Pesticides, October 30, 2024) STARTS TODAY at 2 PM EDTâNATIONAL FORUM: IMPERATIVES FOR A SUSTAINABLE FUTURE. Beyond Pesticides has filed suit against The Scotts Miracle-Gro Company and GreenTechnologies, LLC for allegedly misleading consumers on the hazardous nature of their fertilizer products, which contain sewage sludge (often referred to as biosolids) contaminated with per- and polyfluoroalkyl substances (PFAS). The group filed two cases, Beyond Pesticides v. Miracle-Gro Co. and Beyond Pesticides v. GreenTechnologies, LLC, in D.C. Superior Court on October 25, 2024. The complaint alleges that, as part of their marketing, these companies tell consumers that their fertilizers are âeco-friendlyâ and âsustainable,â when, in fact, the products contain hazardous substances. The complaint cites test results showing PFAS residues in the companiesâ fertilizers and numerous scientific studies on the adverse effects of PFAS to public health, wildlife, and pollinators.  PFAS, known as âforever chemicalsâ due to their ability to persist in the environment, are endocrine disruptors linked to developmental issues, cancers,âŻmetabolic, cardiovascular and reproductive harm, damage to the liver, kidneys, and the respiratory system, as well increased chances of disease infection and severity.âŻTheâŻchemicalsâ immunotoxic effects threaten human health. Beyond Pesticides alleges that consumers are, thus, misled by advertising in which Scotts Miracle-Gro […]

(Beyond Pesticides, October 22, 2024) A recent study, published through the American Chemical Society, analyzes pesticide contamination in riparian soil and plants as a result of flooding from streams in Germany. The authors hypothesize, and then prove, that frequently flooded sites have higher levels of pesticides present due to the pesticides in surface waters contaminating the soil. Results show that the plant vegetation in the contaminated soil then takes up the pesticides, which bioaccumulate and lead to higher contamination that can further cascade throughout the ecosystem and affect terrestrial food webs. â[O]ur study provides evidence from the field that nontarget plant species typical for riparian stream sites receive considerable pesticide exposure via flooding events,â the authors share. This exposure, and subsequent bioaccumulation in plants, threatens the food web, as many riparian plants are a vital food source for insects. According to the authors, flooding events, and their impact on pesticide contamination within soil and plants, are rarely investigated. This study, âmeasur[ing] 98 pesticides and metabolites in plants and root-zone soils sampled at five streams situated in an area in Southwest Germany characterized by intensive agricultural land use,â highlights the differences in contamination between frequently flooded and rarely flooded areas and […]

Beyond Pesticides (October 17, 2024) On September 30, 2024, the U.S. Environmental Protection Agency (EPA) opened a public comment period about production of specific per- and polyfluoroalkyl substances (PFAS, also known as âforever chemicalsâ)âincluding perfluorooctanoic acid (PFOA), perfluorononanoic acid (PFNA), and perfluorodecanoic acid (PFDA). EPA is collecting information on the fluorination process of high-density polyethylene (HDPE) and other plastic containers to inform possible regulatory action under the Toxic Substances Control Act (TSCA). The deadline for submitting comments is November 29, 2024. PFOA and twelve other PFAS compounds are created during the fluorination of HDPE plastic containers by Inhance Technologies, LLC, the only U.S. company manufacturing containers using this fluorination technique (see here). Studies by EPA, independent researchers, and the company itself demonstrate that PFAS leaches from container walls into contents, exposing millions to these toxic chemicals without their knowledge. EPA notes, âLong-chain PFAS like PFOA, PFNA, and PFDA build up in our bodies and the environment over time. Even small amounts can significantly contribute to peopleâs long-term exposure and health risk for cancers, impacts to the liver and heart, and immune and developmental damage to infants and children.â The adverse effects of PFAS exposure are linked to serious health issues, […]

(Beyond Pesticides, October 9, 2024) An agrichemical industry-funded study published in International Journal of Agricultural Sustainability dissects the development of national organic standards and opportunities that can be applied in expanding the use of âregenerativeâ agriculture. Not surprisingly, the study authors offer support for integrated pest management (IPM) and reassurance of a rigorous pesticide registration review process before the chemicals are marketed. The study included a survey of five farmers, who farm a total of 100,000 acres, but do not have extensive experience farming organically. For those practicing regenerative organic practices and organic advocates, the bottom line is that the study concludes that a list of criteria that would be needed for regenerative agriculture criteria (e.g., list of allowed substances) already exists within the standards and requirements of the 1990 Organic Foods Production Act (OFPA) and the National Organic Program. Environmental and public health advocates are concerned about this piece representing an industry position being cloaked in an academic journal serving as an obstacle to the widespread adoption and improvement of organic principles and practices. The study was written by four authors with varying levels of connections to CropLife America (the major agrichemical industry trade group), including academic researchers with […]

(Beyond Pesticides, September 18, 2024) A literature review in Trends in Analytical Chemistry analyzes scientific articles from the last ten years from around the globe that identify more than 300 pesticides in bee pollen. Bee pollen, often used as an edible dietary supplement, is not regulated for pesticide residues, which sparks concern for human exposure due to contamination with pesticides, heavy metals, metalloids, and mycotoxins. âBee pollen is a food supplement that is receiving increasing attention for its nutraceutical and therapeutic properties. However, several uncertainties on the safety of this beekeeping product still exist. The present work addressed this issue through the critical evaluation of 61 studies, published over the 2014â2024 period,â the Spanish authors state. Bee pollen is produced by honey bees. After they forage on flowers and gather pollen on their hind legs (in pollen baskets or corbiculae) to transport back to the hive, it is moistened with nectar and salivary secretions to create bee pollen in the form of pellets. While the composition of bee pollen can vary between geographical locations with different flowers, the studies reviewed all utilize mass spectrometry to pinpoint pesticides, as well as mycotoxins (created by naturally occurring mold spores), that threaten human […]

(Beyond Pesticides, September 13, 2024) While chemical companies persist in pushing simplistic solutions to complex problems, there is a large amount of evidence that organic farming presents effective solutions to many of those problems. Now there is new evidence that organic agriculture prevents the untold harms of pesticide-driven monoculture. In a new study, German researchers compared 16 agricultural landscapes in Lower Saxony and northern Hesse that had different combinations of semi-natural habitat, organic practices, and annual and perennial flower strips. Overall, the researchers find that organic farming provides the highest benefit to the bees, along with the presence of diverse flowering plants in and near monoculture fields. The study compares the effects of three honey bee conservation methods on the prevalence of the parasitic mite Varroa destructor and the 11 parasites Varroa transfers to bees, and the impact of these destructive organisms on bee colony growth. The findings were reported in the June issue of the Journal of Applied Ecology. Organic practices lead directly to lower parasite load and higher colony growthâessentially, the more organic crops, the more bees, and the more parasites, the fewer bees. Pesticides plus monoculture doubles the damage: Pesticides increase mortality, damage beesâ immune systems, and […]

(Beyond Pesticides, September 11, 2024) A literature review in Environments, written by researchers from South Korea and Ghana, highlights the threat to nontarget species and the biodiversity of insects that occur as a result of agricultural pesticide use. âInsects have experienced a greater species abundance decline than birds, plants, and other organisms, which could pose a significant challenge to global ecosystem management. Although other factors such as urbanisation, deforestation, monoculture, and industrialisation may have contributed to the decline in insect species, the extensive application of agro-chemicals appears to cause the most serious threat,â the authors state. The so-called âinsect apocalypseâ has been reported with one-quarter of the global insect population lost since 1990. The authors, seeking to summarize the decline in insect species richness and abundance, link reliance on petrochemical pesticides and synthetic fertilizers to cascading negative impacts. Insects provide many important services, such as maintaining healthy soil, recycling nutrients, pollinating flowers and crops, and controlling pests. These nontarget and beneficial species are at risk through pesticide exposure, both directly and indirectly, which then affects these essential functions.  âExtensive and indiscriminate pesticide application on a commercial scale affects insect species abundance and non-target organisms by interfering with their growth, […]

(Beyond Pesticides, September 10, 2024) Results from a natural experiment, published in Science, shows ecosystem disruption of bat populations with cascading impacts on human health. Eyal Frank, PhD, an assistant professor of the Harris School of Public Policy at the University of Chicago, links increased insecticide use in croplands in the absence of bat species to a rise in infant mortality. As Dr. Frank says in an article in Science Daily, â[B]ats do add value to society in their role as natural pesticides, and this study shows that their decline can be harmful to humans.” Many farmers rely on bats as alternatives to pesticides to protect their crops from insects, but White-Nose Syndrome (WNS) has greatly impacted bat populations since 2006. With the collapse of many bat populations in counties in North America, these farmers turn to toxic chemicals to replace the ecosystem services bats usually provide. These chemicals, however, lead to ripples through the ecosystem and endanger human health. WNS is an invasive fungus (Pseudogymnoascus destructans) found in caves that affects bats during hibernation. As highlighted in an article in the New York Times, three species of bats in North America have been decimated by this syndrome, and bats […]

(Beyond Pesticides, August 28, 2024) The U.S. Environmental Protection Agencyâs (EPA) pesticide labeling requirements fail to adequately communicate acute toxicity levels to the public, as evidenced in a recent study of consumers published last month in the journal Nature. After evaluating whether the current three âsignalâ words (CAUTION, WARNING, DANGER) on pesticide products adequately convey pesticide toxicity, the authors conclude that current labeling may result in âunintended adverse effectsâ because it does not âeffectively communicate toxicity risks to consumers.â The signal words on pesticide labels, based on laboratory animal testing for determining lethal doses, are intended to protect users of the product from exposure that can kill through inhalation, skin absorption, and ingestion of the pesticide. However, the signal words do not warn about long-effects like cancer, neurological diseases, reproductive harm, as well as other adverse effects associated with pesticide exposure. (See Pesticide-Induced Diseases Database.)Â Â The study tests two prototype labels to evaluate the effectiveness of visual elements in communicating toxicity information, citing research in cognitive psychology that indicates visual elements, like images and graphics, are more effective for conveying information than text alone. This is particularly crucial for pesticide labels, where complex toxicity details need to be communicated quickly […]
