(Beyond Pesticides, November 19, 2024) Researchers at Stanford University recently published a study in Cancer, an international interdisciplinary journal of the American Cancer Society (ACS), that reveals a correlation for numerous pesticides with increased prostate cancer occurrence and associated death. The study finds that exposure to 22 pesticides is positively associated with prostate cancer. The 22 pesticides include 2,4‐D, acephate, azoxystrobin, bifenthrin, carbaryl, chloropicrin, cloransulam‐methyl, cyhalothrin‐lambda, diflufenzopyr, diuron, glyphosate, hexazinone, linuron, methyl parathion, pendimethalin, propiconazole, sulfosate, thiamethoxam, thifensulfuron, tribenuron methyl, trifloxystrobin, and trifluralin. (See more on 2,4-D and cancer prevalence here and here.) As prostate cancer is a leading national health concern, the authors investigate agricultural pesticide exposure and compared it to prostate cancer incidence and mortality across counties in the contiguous U.S. “The geographic variation in prostate cancer incidence and mortality suggests that regional environmental factors, such as pesticide exposure, may contribute to the development of prostate cancer,” the researchers postulate. In comparing county‐level associations of 295 pesticides and prostate cancer reports, the authors were able to conduct an environment‐wide association study (EWAS) to determine any statistically significant links. “We acquired annual estimated total usage data (kg per county) for all pesticides reported and applied to agricultural crops grown […]

(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, “A diverse agricultural system can better absorb shocks and maintain productivity, ensuring food security in the face of uncertainty.” 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. “By contrast, diverse cropping systems can enhance resilience, providing a buffer against environmental changes and fostering sustainable food production,” the authors say. Research shows that higher plant diversity disrupts pest life cycles and promotes beneficial insects, […]

(Beyond Pesticides, November 5, 2024) Published in the journal Frontiers in Toxicology, a recent study uncovers serious flaws in the pesticide registration process at the U.S. Environmental Protection Agency (EPA) with an in-depth evaluation of the agency’s failure to protect the public from the harmful effects of five neonicotinoid (neonic) insecticides—as mandated by the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) and amendments, including Food Quality Protection Act (FQPA) of 1996. This coincides with EPA’s ongoing review to renew their approval for the next 15 years (set to be announced in 2025). The report is based on the first comprehensive assessment of unpublished rodent-based Developmental Neurotoxicity (DNT) studies, conducted between 2000-2003 and submitted by pesticide manufacturers as part of the registration process. All five neonicotinoids evaluated—acetamiprid, clothianidin, imidacloprid, thiacloprid, and thiamethoxam—are associated with significant shrinkage of brain tissue at the highest dosage, according to EPA data reports (see acetamiprid, clothianidin, imidacloprid, thiacloprid, and thiamethoxam). However, with little or no data regarding the chemicals’ impacts at low and mid-level dosages, EPA has either failed to find a “No Observed Adverse Effect Level” (NOAEL) or, seemingly at random, set the NOAEL at the mid-level dosage. The evaluation suggests that perinatal exposure to […]

(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. “[O]ur study provides evidence from the field that nontarget plant species typical for riparian stream sites receive considerable pesticide exposure via flooding events,” 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, “measur[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,” 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 ‘forever chemicals’)—including 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, “Long-chain PFAS like PFOA, PFNA, and PFDA build up in our bodies and the environment over time. Even small amounts can significantly contribute to people’s long-term exposure and health risk for cancers, impacts to the liver and heart, and immune and developmental damage to infants and children.” 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 “regenerative” 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. “Bee 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 2014–2024 period,” 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 growth—essentially, the more organic crops, the more bees, and the more parasites, the fewer bees. Pesticides plus monoculture doubles the damage: Pesticides increase mortality, damage bees’ 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. “Insects 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,” the authors state. The so-called “insect apocalypse” 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.   “Extensive 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, “[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 […]

Image: Art Page submission from Sara Grantham, “Sunflower Pollinators”  (Beyond Pesticides, August 23, 2024) A study in Science of The Total Environment calculates and compares pesticide risk in 594 wild bee species associated with crops in North America. Current pesticide risk assessments that analyze effects on bees primarily focus on a limited subset of species and do not provide comprehensive protection of all wild bees. “Species commonly proposed as models for pesticide risk assessments may not accurately represent risk for those bee species facing the highest potential risk in agricultural contexts,” the authors postulate. The researchers continue, “This study presents a novel approach to characterize and compare the relative potential pesticide risk among wild bee species of their association with crops in North America using suites of intrinsic bee traits to quantify species’ vulnerability and extrinsic factors based on the toxic load of crops for bees and the strength of each species’ association with those crops.” In considering multiple factors that vary by species and determining potential harm to each from pesticide exposure, this study highlights the inadequacies of the current risk assessment process used by the U.S. Environmental Protection Agency (EPA).    The system for risk assessment for pesticides that […]

(Beyond Pesticides, July 18, 2024) A recent study in The Journal of Toxicological Sciences shows that a single dose of the neonicotinoid insecticide clothianidin (CLO) induces behavioral abnormalities, predominantly in female mice, throughout key stages of development. In testing mice at various ages, sex-specific changes were identified that highlight not only varied effects on males and females but also how pesticide exposure at a young age can cause lasting impacts throughout adulthood in mammalian species.  The researchers, at the Laboratory of Animal Reproduction and Development at Tohoku University in Japan, “utilized murine [mouse] models to compare the sex-specific differences in behavioral effects following CLO exposure at different developmental stages. [They] orally administered CLO to male and female mice as a single high-dose solution (80 mg/kg) during the postnatal period (2-week-old), adolescence (6-week-old), or maturity (10-week-old), and subsequently evaluated higher brain function.”   As the authors remark, “Most studies on the neurotoxicity of CLO have targeted only males, with limited insights regarding the neurodevelopmental toxicity in females. There are significant sex differences in brain development due to hormonal, genetic, epigenetic, and other sex-specific factors. Moreover, there are also a number of sex-based differences in the prevalence of developmental disorders, such as […]

(Beyond Pesticides, July 16, 2024) Yet another study in the August 2024 journal Ecotoxicology and Environmental Safety has found that exposure to organophosphorus pesticides (OPPs) is correlated with increased suicidal thoughts in some people. This study is just the latest in a long line of studies from around the world that have linked pesticide exposure to mental health conditions, including sleep disorders, depression, and suicidal ideation (SI). As the rate of suicide increased by 30% between 2000 and 2020, there is an urgent public health need to investigate and address all potential contributing factors. A 2019 study, covered in Daily News, found that teens and adolescents living in agricultural areas and exposed to organophosphate (OP) insecticides are at higher risk of depression, In July and January this year, other studies link farmer psychiatric episodes to pesticide exposure, adding to the body of science. Exposure to household pesticides is also linked to depression in a 2020 study.   Study and Methodology  The study entitled “Association between exposure to organophosphorus pesticide and suicidal ideation among U.S. adults: A population-based study,” analyzes information on the mental and physical health of over 5,000 individuals aged 20 and up in the United States. The study aims […]

(Beyond Pesticides, July 11, 2024) Can the health of pollinator hives serve as a nature-based indicator for pesticide residue drift? Researchers in a study published in Science of the Total Environment in June find this to be the case. Through the BeeNet Project, led by the Italian Ministry of Agriculture, Food Sovereignty, and Forestry (MAFSF), researchers detected the presence of 63 different pesticide residues in hives across northern Italy. Of these residues, 15 are not approved for use under European Union (EU) law. Environmental advocates observe the mounting scientific literature on pollinator decline, in part due to the inadequate regulation of toxic petrochemical-based pesticides, as a call to action to push forward land management, agricultural, and climate policy that aligns with organic principles centering on soil health, biodiversity, public health, worker protections, and economic security. Methodology The study is cowritten by a cohort of ten researchers working in the Research Center for Agriculture and Environment in Bologna, Italy—a research institution within the Council for Agricultural Research and Agricultural Economics Analysis (CREA) at MAFSF. Supported by the BeeNet Project (funded by Italian National Fund), BeeNet is a national monitoring project that tracks the health of honey bee and wild bee populations […]

(Beyond Pesticides, July 10, 2024) An article last month in Entomology Today, a publication of the Entomological Society of America, highlights the important findings of a study published earlier this year in the Journal of Insect Science. While there has been debate on whether neonicotinoid (neonic) insecticides or Varroa mites (Varroa destructor) are more detrimental to the survival of bees, evidence suggests that neonicotinoids are not only harmful individually but can increase vulnerability to parasitism from mites in western honey bees (Apis mellifera). The Entomology Today article reads: “Some researchers and organizations have pointed to neonics as directly harming bees. Others have pointed to other issues, like Varroa mite infestation, as more hazardous to honey bee populations.” There is scientific evidence supporting each claim, as both cause stress to bee species that can lead to population decline. The study in the Journal of Science, however, is “the first experimental field demonstration of how neonicotinoid exposure can increase V. destructor populations in honey bees and also demonstrates that colony genetic diversity cannot mitigate the effects of neonicotinoid pesticides.”  As the article states, “The researchers were not looking for impacts on Varroa mites at first. Instead, they were looking to understand how […]

(Beyond Pesticides, July 28, 2024) Most people don’t like bugs, but the fact is that insects form the foundation of human flourishing, both for their ecosystems services, like pollination of food crops, and for their aesthetic joys. But insect populations globally are declining two to four percent a year, with total losses over 20 years of 30-50 percent, according to a new study of the interacting effects of pesticides, climate, and land use changes on insects’ status in the Midwest. Teasing out the relative influence of these stressors has been a major obstacle in determining the causes of the declines and ways to mitigate them. The icon of insect beauty in the U.S. is the monarch butterfly, whose vibrant coloring, elegant form, and spectacular migrations inspire everyone. Beyond Pesticides has covered the distressing decline of these creatures, most recently in the June 24 Daily News. Monarchs prefer milkweed plants, but also visit many other flowers. Milkweed often grows along the margins of fields, so monarchs are widely exposed to pesticides and habitat disturbances associated with agriculture. The new study was published in PLoS One by a team of scientists from the Washington Department of Fish and Wildlife, Michigan State University, […]

(Beyond Pesticides, June 24, 2024) National Pollinator Week ended last week, but the crisis associated with pollinator decline and biodiversity collapse continues. If there were not enough data to prove that regulators are woefully behind the curve in protecting pollinators, yet another study was published during Pollinator Week that reminded regulators, elected officials, farmers, gardeners, all eaters, and lovers of nature that federal, state, and local environmental laws in place have been an abject and unconscionable failure in protecting the biodiversity that supports all life. The study, “Insecticides, more than herbicides, land use, and climate, are associated with declines in butterfly species richness and abundance in the American Midwest,” published in PLOS ONE, cries out as a further warning that the U.S. Environmental Protection Agency’s (EPA) “mitigation measures,” which tinker with limited pesticide restrictions, represent a catastrophic disregard for the scientifically documented facts, according to environmental advocates. Daily News will cover this study in more detail in a later piece, however, the abstract of the journal piece is worth reprinting here in reflecting on Pollinator Week: “Mounting evidence shows overall insect abundances are in decline globally. Habitat loss, climate change, and pesticides have all been implicated, but their relative effects […]

(Beyond Pesticides, June 21, 2024) A recent review of the scientific literature, published in Science of The Total Environment, analyzes multiple species of bees on a molecular level to better understand the poisoning mechanisms that could, as the authors see it, inform chemical risk assessments with more precision. The mechanisms “implicated in the tolerance of bees to specific pesticides, and thus as determinants of insecticide sensitivity, … include metabolic detoxification, insecticide target proteins, the insect cuticle and bee gut microbiota,” the authors write. This review references more than 90 studies performed over the last 30+ years, with most being published in the last 5-10 years, as the understanding and importance of molecular determinants of bee sensitivity has emerged. Pollinators, such as bees, provide crucial ecosystem services by pollinating both wild plants and essential crops. The exposure these insects are subjected to threatens their existence, which occurs through pesticide contamination that can lead to impacts on growth and development or even colony collapse.    “While bees have only been exposed to human-made pesticides over the recent past (last 80 years) they have co-evolved with plants and fungi which produce a range of xenobiotics, including plant allelochemicals and mycotoxins,” the authors state. […]

(Beyond Pesticides, June 17, 2024) Every year, Beyond Pesticides announces National Pollinator Week—this year beginning today, June 17—to remind eaters of food, gardeners, farmers, communities (including park districts to school districts), civic organizations, responsible corporations, policy makers, and legislators that there are actions that can be taken that are transformative. All the opportunities for action to protect pollinators, and the ecosystems that are critical to their survival, can collectively be transformational in eliminating toxic pesticides that are major contributors to the collapse of biodiversity. This is why Beyond Pesticides starts most discussions and strategic actions for meaningful pollinator and biodiversity protection with the transition to practicing and supporting organic. In launching National Pollinator Week, Beyond Pesticides makes suggestions for individual actions to increase efforts to think and act holistically to protect the environment that supports pollinators. The impact that people have starts with grocery store purchases and the management of gardens, parks, playing fields, and pubic lands. The introduction of pesticides into our food supply and our managed lands has contributed to a downward spiral that is unsustainable. The good news is that it is now proven that we do not need toxic pesticides to grow food productively and profitably […]

(Beyond Pesticides, June 14, 2024) The influence of the chemical industry over public policy and regulation, especially in agriculture, is glaringly obvious and has little popular support, yet no one can seem to do anything about it. Numerous analyses have detailed the ways this influence is applied—through lobbying and political donations including dark money; industry experts named to regulatory agency scientific advisory boards; and the massive public relations machines that create and sustain public uncertainty using the tobacco industry playbook revealed by Naomi Oreskes and Erik Conway in their 2010 book Merchants of Doubt. A more insidious tendril of industry influence is explained in U.S. Right to Know’s (USRTK) report, released this month, on pesticide manufacturers’ infiltration of the Entomological Society of America (ESA). The report, “Anatomy of a science meeting: How controversial pesticide research all but vanished from a major conference,” examines the ESA’s 2023 annual meeting—its program, sponsorships, presentations, panelists, poster sessions, meet-and-greets, budget, revenue sources, and other aspects of the event. What is revealed is a systematic and comprehensive industry presence throughout the society and its meeting. A direct consequence is the near-elimination of any scientific presentations addressing the effects of neonicotinoid pesticides on insects, particularly bees. […]

(Beyond Pesticides, June 13, 2024) A study published in Conservation Letters, a journal of the Society for Conservation Biology, exposes critical shortcomings in the U.S. Environmental Protection Agency’s (EPA) ecological risk assessment (ERA) process for modeling the risks that pesticides pose to bees and other pollinators. For the study, “Risk assessments underestimate threat of pesticides to wild bees,” researchers conducted a meta-analysis of toxicity data in EPA’s ECOTOX knowledgebase (ECOTOX), an EPA-hosted, publicly available resource with information on adverse effects of single chemical stressors to certain aquatic and terrestrial species. The meta-analysis found that the agency’s approach, which relies heavily on honey bee data from controlled laboratory studies, drastically underestimates the real-world threats from neonicotinoid insecticides (and likely other pesticides) to native bees and other pollinators. The study “challenges the reliability of surrogate species as predictors when extrapolating pesticide toxicity data to wild pollinators and recommends solutions to address the (a)biotic interactions occurring in nature that make such extrapolations unreliable in the ERA process.” Beyond Pesticides executive director Jay Feldman remarked, “EPA’s ecological risk assessment process is fundamentally flawed and puts thousands of bee species at risk of pesticide-caused population declines and extinctions.” Mr. Feldman continued, “This underscores the urgent […]

(Beyond Pesticides, May 30, 2024) The House Agriculture Committee voted 33-21 on May 23 to move the Farm, Food, and National Security Act out of committee after a contentious markup and onslaught of amendments that undermine water health, soil health, and local democratic authority to protect people and the environment from toxic pesticide exposure. One of nearly sixty amendments introduced in the markup last week included the continuation of a decade-long attack on National Pollutant Discharge Elimination System (NPDES) permit via Clean Water Act (CWA) for pesticide discharge. What was most illuminating however was not the passage of the bill itself, but Big Agriculture’s raucous approval. Advocates see pesticide industry and its allies’ support for what it is—the reliance on petrochemical-based pesticides leading to economic instability, ecosystem collapse, and the degradation of democratic institutions. With support for entrenched dependency on petrochemical pesticides and fertilizers, the committee’s bill requires taxpayers to pay through the government’s crop insurance program for escalating losses caused by chemical-intensive farming practices, contributing to yield losses that the U.S. Department of Agriculture (USDA) says are “natural causes such as drought, excessive moisture [e.g., floods], hail, wind, frost, insects, and disease. . .” However, the frequency of these […]

(Beyond Pesticides, May 24, 2024) Even allegedly “low-toxicity” pesticides such as flupyradifurone (insecticide), azoxystrobin, and difenoconazole (fungicides) pose adverse health effects to solitary ground-nesting squash bees (Xenoglossa pruinose), according to a study published in Biological Sciences. Fungicide exposure led to less pollen collected per flower, while exposure to flupyradifurone (FPF) produced larger offspring (which make it more challenging for them to fly). Simultaneous exposure to the three pesticides “induced hyperactivity in female squash bees relative to both the control and single pesticide exposure, and reduced the number of emerging offspring per nest compared to individual pesticide treatments.” With United Nations Food and Agriculture Organizations-sponsored World Bee Day earlier this week, now more than ever advocates are calling for the elimination of toxic insecticide classes, such as neonicotinoids and butanolides, and their wholesale replacement with organic land management principles. This study was written by Sabrina Rondeau, PhD, postdoctoral Fellow in the Department of Biology at the University of Ottawa, and Nigel E. Raine, PhD, professor at University of Guelph’s School of Environmental Science. Published on March 20, 2024, the researchers delve into the individual and co-exposure impacts of two fungicides and one insecticide, which is important, given the documented synergistic effects […]
