(Beyond Pesticides, April 8, 2026) Researchers at the U.S. Geological Survey (USGS) assessed pesticide and PFAS (per- and poly-fluoroalkyl substances) contamination in ten agricultural streams in the San Joaquin and Sacramento Valleys (Central Valley) in 2024, detecting 60 pesticides, synergists, and associated transformation products, including 12 fluorinated pesticides (Dithiopyr, Trifluralin, Fluridone, Oxyfluorfen, Penoxsulam, Flubendiamide, Bifenthrin, Flonicam, Indoxacarb, Cyhalothrin, Fluopyram, and Penthiopyrad) that meet the Organisation for Economic Cooperation and Development (OECD) definition of qualifying as PFAS. It is alarming to learn that “the OECD fluorinated pesticides were generally detected more frequently and at higher concentrations” relative to the 48 other compounds.  Relatedly, research finds products containing three of the detected pesticides (Methoxyfenozide, Imidacloprid, and Piperonyl Butoxide) associated with various PFAS, and according to the authors, there are a handful of active ingredients, such as the insecticide Methoxyfenozide and the fungicide Azoxystrobin, detected in 100 percent of collected samples. Their entire findings were published in Environmental Science & Technology Letters in March 2026. This research is critical to our understanding of the pervasiveness and ubiquity of multi-chemical pollution that impacts one of the most productive agricultural regions in the country. The regions encompassing these two valleys make up just one percent of total U.S. farmland, […]

(Beyond Pesticides, March 19, 2026) A study of water contamination in Protected Areas (PAs) in Brazil, published in Science of The Total Environment, highlights the pervasiveness of pesticides. “Our objective was to evaluate the effectiveness of these PAs in mitigating pesticide contamination in watercourses and to investigate how land use patterns influence the presence of pesticide residues,” the authors state. “We found pesticide compounds in biofilms [mutually beneficial community of microorganisms] both inside and outside PAs’ streams, with no buffer effect of these protected lands against herbicides, insecticides and fungicides, contrary to our expectations.” In analyzing epilithic biofilms, which are communities of microorganisms that adhere to submerged rocks and surfaces in aquatic ecosystems, the researchers find residues of 14 pesticide compounds and one metabolite across the 19 sampling sites, threatening aquatic organisms and ecosystem functioning. The authors say, “[M]onitoring epilithic biofilms in PAs provides valuable information by detecting pesticide compounds that analysis of surface water and sediments might miss.” Through various routes, such as runoff to waterways, leaching into groundwater, and aerial drift, pesticides are ubiquitous in the environment, even in remote and protected areas. As the testing of the freshwater epilithic biofilms in this study reveals 15 pesticide residues […]

(Beyond Pesticides, March 13, 2026) In a press release on March 10, 2026, Public Employees for Environmental Responsibility (PEER) cites independent test data on the herbicide indaziflam with detections of per- and poly-fluoroalkyl substances (PFAS), the “forever chemicals” known for significant toxicity at low level exposure and high persistence. The product, Rejuvra™, is produced by Envu (a former division of Bayer) and “is being sprayed and considered for use across millions of acres of Bureau of Land Management (BLM) and US Forest Service land.” Scientific literature connects indaziflam and PFAS with adverse effects to human, soil, and biodiversity health, raising serious concerns about their wide use in agriculture and general land management of lawns, parks, playing fields, ornamentals, fence lines, rights-of-way, rangeland, open space, and Christmas trees. Background As a pre-emergent weed killer used to kill annual grasses and unwanted broadleaf plants, the fluoroalkyltriazine herbicide is broadly labeled for use in residential areas, commercial ornamental and sod production, forestry, and mostly orchard crops. While indaziflam is considered a “selective” herbicide, it actually kills and prevents germination of a wide range of broad-leaved plants and grasses and comes close to being a soil sterilant.  Since the chemical is subject to drift […]

(Beyond Pesticides, February 18, 2026) Research finds that widespread agricultural pesticide use increases chronic dietary exposure in poultry and leads to adverse reproductive effects, despite meeting legal residue limits. As published in Poultry Science by researchers in Poland, the study analyzes low-dose exposure of roosters (Gallus gallus domesticus) to the fungicide tebuconazole (TEB), the insecticide imidacloprid (IMI), and the weed killer glyphosate (GLP) individually and in mixtures, with all concentrations at or below the maximum residue limits (MRLs) established by the European Union (EU). “Sub-MRL pesticide exposure impaired male reproductive function, with the most pronounced effects observed following combined treatments,” the authors report. They continue: “[E]xposure resulted in reduced semen quality, decreased fertility and hatchability, and increased embryo mortality, particularly in groups receiving IMI alone or in combination. These functional impairments were accompanied by detectable pesticide residues in reproductive tissues and body fluids, as well as modulation [modification/alteration] of local and systemic immune parameters.” The results of the experiment highlight how combined pesticide exposure, resulting from common use of multiple pesticide active ingredients concurrently, produces “stronger and more persistent reproductive effects than individual compounds, indicating mixture-specific toxicity.” This study is particularly important, as it represents the chronic exposure to MRL-compliant […]

[Update on February 9, 2026: In a press release on Friday, February 6, titled “EPA Implements Strongest Protections in Agency History for Over-the-Top Dicamba Use on Cotton and Soybeans for Next Two Growing Seasons,” the U.S. Environmental Protection Agency (EPA) continues to ignore the wide body of science that documents harms from dicamba, as well as the viability of alternative methods, in establishing what the agency is boasting are “the strongest protections in agency history for over-the-top (OTT) dicamba application on dicamba-tolerant cotton and soybean crops” as a direct response to the “strong advocacy of America’s cotton and soybean farmers.” These so-called “strong protections” are described as a way to ensure farmers can access the tools they “need” while also protecting the environment from dicamba’s harmful drift. In using “gold-standard science and radical transparency,” EPA created new label restrictions for the next two growing seasons that include “cutting the amount of dicamba that can be used annually in half, doubling required safety agents, requiring conservation practices to protect endangered species, and restricting applications during high temperatures when exposure and volatility risks increase.” Relying on unenforceable label restrictions and mitigation measures, however, fails to adequately protect health and the environment. See […]

(Beyond Pesticides, February 3, 2026) In analyzing the direct and indirect effects of pesticides that act simultaneously upon macrozoobenthos communities (invertebrates living in or on sediment) in standing small water bodies (SWBs) in Germany, researchers find high risks to biodiversity and ecosystem functioning. Published in Hydrobiologia, the experiment finds high risks to invertebrates and highlights how both direct and indirect effects are vital to comprehensive assessments of pesticides. While typically overlooked in regulatory reviews, SWBs are defined as shallow standing or running freshwaters “with a surface area of less than 50 hectares (ha),” such as lakes or ponds, including farm ponds, as well as headwater streams, springs and flushes, and ditches. SWBs are biodiversity hotspots that contribute to numerous ecosystem services and are adversely affected by agricultural land use effects such as pesticide contamination. “Holistic assessments of pesticide effects on invertebrate communities in standing small water bodies have, however, not yet been successful,” the authors note. To address this, the researchers developed an indicator for evaluating pesticide impacts on macrozoobenthos communities, populated with aquatic invertebrates, such as snails, worms, crayfish, and clams, through indirect toxic effects on aquatic plants called INPOND: INdirect Pesticide impacts ON Diversity in standing small water […]

(Beyond Pesticides, January 29, 2026) A study of ecotoxicity risk from neonicotinoid insecticides, published in Environmental Chemistry and Ecotoxicology, finds that chemicals in this class of pesticides, particularly dinotefuron, increase the body temperature of Apis mellifera (European honey bee) and subsequently accelerate the translocation (movement) of contaminants into hives by the honey bees. The research indicates that neonicotinoids affect acetylcholine receptors in the nervous system, leading to an “elevation in octopamine titer [neurotransmitter/hormone] and subsequent increase in the body temperature of honeybees,” the authors report. They continue: “Furthermore, we observed a considerable upregulation [of] the expression of a flight gene flightin in honeybees. This gene accelerates the homing behavior of honeybees and facilitates the rapid and frequent transport of neonicotinoid pesticide-contaminated nectar to the hive.” In describing their results, the researchers state: “For the first time, we propose that neonicotinoid pesticides accelerate the homing ability of honeybees by affecting their body temperature, which leads to more neonicotinoid pesticides entering the hive and explains the prevalence of neonicotinoids and at higher concentrations in terms of their effects on the honeybee body temperature that enhances homing.” This accelerated movement of neonicotinoid pesticides into honey bee hives heightens the toxicity risks to honey […]

(Beyond Pesticides, January 22, 2026) Published in Environmental Research, a review of experimental studies by George Mason University researchers regarding reproductive toxicity of neonicotinoid pesticides (neonics) in rodents finds that all studies “demonstrated negative impacts on male reproductive endpoints in association with neonic exposure, including reduced sperm count, reduced sperm motility, and altered sperm morphology.” These studies highlight how neonics, designed to target insect nervous systems, can affect mammalian systems, representing risks to human health. Criteria for inclusion in the review was restricted to endocrine and/or reproductive outcomes in male rats and mice, leading the authors to analyze 21 studies published between 2005 and 2025. “This narrative review employed a systematic approach and determined that neonics exhibit reproductive toxicity in male rats and mice, particularly impairing testicular function and sperm quality at high exposure levels,” the researchers report. They continue, “Despite species-specific differences, the conserved nature [core mechanism] of reproductive processes across mammals supports the relevance of these findings to human health.” Study Background Neonicotinoids are a class of insecticides that share a common mode of action that affects the central nervous system of insects, resulting in paralysis and death. There is a wide body of science on the effects […]

(Beyond Pesticides, December 16, 2025) Through a literature review and data analysis of almost 2,000 soil samples, the authors of a recent study find negative effects on the presence of plant-beneficial bacteria (PBB) in soil with pesticide exposure, particularly bacteria with plant growth-promoting traits that are essential for crop productivity. The study, published in Nature Communications, by researchers at China’s Shaoxing University and Zhejiang University of Technology, adds to scientific literature documenting the effects of pesticides on soil health. “Pesticides not only reduce PBB diversity as individual factors, but they also exert synergistic negative effects with other anthropogenic factors… further accelerating the decline in PBB diversity,” the researchers state. They continue, “Increased pesticide risk also leads to a loss of functional gene diversity in PBB about carbon and nitrogen cycling within essential nutrient cycles, and a reduction in specific amino acid and vitamin synthesis.” In elucidating these impacts, this study reinforces previous research that connects pesticide use with deteriorating soil health, further stressing the urgent need for adopting a systems-wide transition to organic agricultural and land management practices. Soil Microbiome Health As the authors discuss, plant–soil–microbe interactions play a critical role in the growth, development, and overall health of plants, […]

(Beyond Pesticides, December 5, 2025) A study published this month in Environmental Pollution analyzes the role of neonicotinoid insecticide exposure on bird populations, finding a significant negative effect of imidacloprid use on insectivorous bird abundance. In comparing the effects of the insecticide imidacloprid on bird abundance in France before and after the 2018 ban, the researchers show a weak recovery of bird populations after 2018. The persistent nature of imidacloprid, however, as well as the continued use of other petrochemical pesticides that have adverse effects on bird species, continues to impact populations of all types of birds and other wildlife, leading to cascading impacts on biodiversity.    “Our study shows that imidacloprid is a major covariate of the abundance of birds, in addition to other pesticides that are also negatively related to bird populations, and that these effects are not uniform across species,” the authors report. They continue in saying that the relationship between neonicotinoids and bird abundance varied across bird diets, as “the abundance of insectivorous birds was consistently lower under increasing pesticide use, in particular imidacloprid.” Background As shared in the study and on Beyond Pesticides’ Birds page, bird species can be exposed to pesticides directly through ingestion […]

(Beyond Pesticides, December 4, 2025) In a news release last week on November 26, 2025, the U.S. Environmental Protection Agency (EPA) “issued a comprehensive fact-check addressing dangerous misinformation circulating about EPA’s recent pesticide approvals” that, according to health and environmental advocates, continues to deceive the public about the true risks for health and the environment from petrochemical pesticides including, but not limited to, per- and polyfluoroalkyl substances (PFAS). Also published on November 26, coverage titled The EPA Is Embracing PFAS Pesticides. These Are The Health Risks in Time further highlights EPA’s deficiencies and the threats of PFAS, which Beyond Pesticides has extensively covered. (See here and here.)  The controversy erupted as a result of EPA’s latest proposal to allow a new fluorinated pesticide to the list of four other similar compounds now widely available for use in homes and gardens, buildings, and agriculture. The newest pesticide proposed for EPA registration, epyrifenacil (agricultural weed killer), joins cyclobutrifluram (soil fungicide/nematicide), isocycloseram (household and agricultural insecticide), diflufenican (lawn and agricultural weed killer), and trifludimoxazin (agricultural weed killer), making a total of five PFAS pesticide proposals this year that have been associated with national and worldwide contamination of food, land, and water. Two of these, cyclobutrifluram and isocycloseram, have been approved. “Instead of constraining the use of fluorinated pesticides—persistent and highly toxic […]

(Beyond Pesticides, October 28, 2025) A California-based population study published in BMC Public Health finds that “7.5 [percent] of all pregnant people in California who gave birth in 2021 lived within 1 km [kilometer] of agricultural fields where OP pesticides [organophosphates] had been used during their pregnancy. . .” Despite a 54 percent decrease in overall use of the neurotoxic insecticide chlorpyrifos in the state between 2016 and 2021, after a statewide ban on the organophosphate insecticide in 2016, researchers found that in one California county, “more than 50 [percent] of pregnant people lived within 1 km of OP pesticide use.” Significant disparities were found in terms of elevated exposure to pesticides, “with Hispanic/Latine, young people, and residents of the predominantly fruit and vegetable growing Central Coast region being most likely to live near OP pesticide applications during pregnancy.” The authors suggest that “regulatory changes to limit use or restrict applications in close proximity to residential areas could have a substantial public health benefit on children’s brain development.” These findings add to the existing scientific literature on perinatal and maternal pesticide exposure associated with adverse long-term health effects for children and mothers. They also serve as a reminder to public […]

(Beyond Pesticides, October 23, 2025) A global literature review of pesticide residues in marine seaweed, published in Marine Pollution Bulletin, highlights the widespread presence of pesticides in bioindicator species. As vital coastal primary producers, seaweed acts as a key indicator for regional pesticide contamination patterns. The bioaccumulation within seaweed species also threatens consumers, including humans, as the chemicals can biomagnify as they move through the food web. Pesticide contamination in waterways allows residues to bioaccumulate in seaweed species, presenting risks to public health, biodiversity, and ecosystem functioning. In addition to the support seaweeds provide for ecosystems, they provide food sources for a multitude of organisms and are of growing socioeconomic importance. “This systematic review identifies, critically evaluates, and synthesizes recent global literature (2015–2024) on pesticide residues detected in seaweeds to delineate contamination patterns,” the authors share. The findings highlight the harmful impacts of petrochemical pesticides on multiple species. Many aquatic species rely on seaweed as a food source, including fish, sea urchins, crabs, snails, brittle stars, and marine mammals such as manatees and sea turtles. Even bacteria and filter feeders consume seaweed when it is decomposed. Birds and land mammals also consume seaweed, including humans who utilize seaweed in various […]

(Beyond Pesticides, October 15, 2025) The latest Scientific Investigations Report for 2025 from the U.S. Geological Survey (USGS), entitled “National Water Quality Program: Multidecadal Change in Pesticide Concentrations Relative to Human Health Benchmarks in the Nation’s Groundwater,” finds moderate concentrations of five pesticides, with the highest percentages in agricultural wells, and concentrations of the carcinogenic soil fumigant DBCP (1,2-dibromo-3-chloropropane), which also causes infertility, that are greater than the maximum containment level, despite being banned over 45 years ago. These results highlight the persistence of pesticides used in agriculture and the elevated risks of pesticide contamination in agricultural areas. This report monitors concentrations of pesticides in well networks across the U.S. in decadal intervals, with this last one incorporating data ranging from 1993-2023. Additionally, DBCP in one well network in the San Joaquin-Tulare River Basin in California continues to be assessed due to previous levels exceeding the human health benchmark (HHB) established by the U.S. Environmental Protection Agency (EPA). The limitations of the study are disclosed in the text of the report. As the authors state: “Only pesticides with an HHB were included in the multidecadal pesticide change analysis… The total number of pesticides included in this study is less than […]

(Beyond Pesticides, August 26, 2025) A scientific review in World’s Poultry Science Journal highlights the adverse health effects on avian species from exposure to the widely used weed killer glyphosate (Roundupᵀᴹ) throughout the process of poultry production. The herbicide enters the poultry production system through residues in genetically engineered feed. An earlier article in Scientific Reports concludes that glyphosate’s (GLP) “widespread application on feed crops leaves residues in the feed,” while residues are “found to be common in conventional eggs acquired from grocery stores.” In analyzing the biochemical, toxicological, and ecological impacts of glyphosate on poultry, particularly chickens, the authors find a wide body of evidence linking glyphosate and its metabolite (breakdown product) aminomethylphosphonic acid (AMPA) to debilitating hazards that extend beyond mortality. These sublethal effects include disruption of the gut microbiome and gastrointestinal disease; decreased productivity and diminished reproductive health; hepatic and kidney toxicity; growth and developmental impacts, including teratogenicity and embryotoxicity; endocrine disruption and oxidative stress; and impaired immune functions. The effects of glyphosate, as have long been documented in the scientific literature and covered by Beyond Pesticides here, range from negative impacts on biodiversity and the environment to food safety risks and human health implications. Residues of […]

(Beyond Pesticides, August 14, 2025) A review in Clinical and Experimental Obstetrics & Gynecology links various classes of environmental pollutants including pesticides and per- and polyfluoroalkyl substances (PFAS), both of which Beyond Pesticides has extensively covered, to adverse effects on the female reproductive system and common mechanisms of toxicity. These chemicals “disrupt the hypothalamic-pituitary-gonadal axis (HPG), impair ovarian function, and contribute to reproductive dysfunction through mechanisms such as oxidative stress, hormonal disruption, and epigenetic [gene expression or behavior] modifications,” the authors say. This leads to menstrual irregularities, infertility, and pregnancy complications, as well as increases in the risk of reproductive system disorders such as endometriosis, polycystic ovary syndrome (PCOS), and ovarian cancer, among others. “Additionally, transgenerational effects mediated by epigenetic modifications, germ cell damage, and placental transfer may adversely affect offspring health, increasing the risk of reproductive dysfunction, neurodevelopmental disorders, metabolic diseases, and cancer,” the researchers explain. This study, integrating recent epidemiological and experimental findings, provides an overview of major chemical classes that threaten women’s health and highlights the need for immediate action. As the authors point out, female reproductive health is important not only for those who choose to plan for a family but also for the overall well-being […]

(Beyond Pesticides, August 5, 2025) A biomonitoring study in Environmental Geochemistry and Health, focused on small-scale farms in Pahang, Malaysia, analyzes levels of essential and toxic elements in hair and nail samples from chemical-intensive and organic farmers. While the results reveal elements that correlate with specific farming practices, common elements to both chemical-intensive and organic farming highlight the role of pesticide drift in off-target contamination, diminishing some of the benefits of organic agriculture. The persistent and pervasive nature of many pesticide products results in exposure patterns, in addition to direct occupational exposure on chemical-intensive conventional farms, that trespass onto organically managed land and threaten health and the environment—raising policy and practice issues needed to safeguard the public. Cameron Highlands in Malaysia is a region known for intensive pesticide use as well as for its vegetable and flower farming, where both conventional and organic agriculture exist in close proximity. “Despite different agricultural approaches, both groups remain at risk of environmental exposure due to long-term pesticide application in the region,” the authors write. They continue, “While organic farming practices may reduce direct exposure to synthetic agrochemicals, the risk of cross-contamination from surrounding conventional farms remains a concern due to environmental dispersion through […]

(Beyond Pesticides, July 30, 2025) The definition of per- and polyfluoroalkyl substances (PFAS), also known as “forever chemicals” due to their persistence, continues to be debated in regulatory agencies, with many scientists arguing that certain types of chemicals in this vast group are not accurately captured in risk assessments. A wide body of science on the adverse health and environmental effects of PFAS exists, as these synthetic chemicals have become ubiquitous in nature, wildlife, and humans, as demonstrated by biomonitoring studies. Recent research, documented in a literature review in Environmental Science & Technology and additional articles, highlights the importance of a universal, cohesive definition of PFAS that incorporates all fluorinated compounds, including the long carbon chain PFOA (perfluorooactanoic acid) and PFOS (perfluorooctanesulfonic acid) as well as the ultrashort-chain perfluoroalkyl acids (PFAAs). In order to protect health and the environment from the ever-increasing threat of both long and short chain PFAS’ adverse effects, including cancer, endocrine-disrupting effects, and immune system damage, a comprehensive definition of the compounds causing harm is critical to adequate protection and regulatory decisions. The multitude of sources of PFAS and various exposure routes leads to widespread contamination of the environment and organisms. PFAS in agriculture represents a […]

(Beyond Pesticides, June 26, 2025) A review article in Nature Reviews Earth & Environment highlights how the pesticides used in global crop production pose risks to ecosystems and human health through multiple pathways. As the authors note, “Once applied to crops, pesticides are transported through surface and groundwater flows, atmospheric dispersion and wildlife migration.” Residues in food products, such as fruits and vegetables, as well as bioaccumulation within animals that are consumed as food, also threaten consumers around the world, particularly those relying on international trade. The researchers note: “In this Review, we summarize the pathways through which synthetic pesticides transcend boundaries, focusing on the impacts of their use in food production… First, we explain how environmental flows contribute to transporting pesticides to regions far from their original source. Next, we examine the role of international food trade in causing transboundary exposure and impact of pesticide use.” As a result, the study calls for prioritizing biodiversity and human health through sustainable methods while maintaining yield to support the growing population. The use of pesticides in chemical-intensive agriculture has exponentially increased since their first synthesis in the late 1930s. “Globally, pesticides were applied on agricultural land at an average rate of […]

(Beyond Pesticides, June 6, 2025) Published in Environmental Pollution, a study of commercial dry pet products finds dietary pesticide residues in dog and cat food, “highlighting the urgent need for improved regulatory frameworks to address the presence of non-approved pesticides in pet food.” Additionally, the researchers point out: “Current regulatory frameworks primarily assess the toxicity of individual pesticide compounds, yet real-world exposure involves complex mixtures that may lead to additive or synergistic effects. The presence of multiple residues in a single sample suggests that companion animals may be subjected to combined toxicological burdens that are not yet fully understood.” (See studies here, here, and here.) The researchers assess pesticide contamination, and their associated toxicological risks, in 83 total food products for dogs (43) and cats (40). Of the foods tested, the researchers found a total of 51 pesticides, many of which are banned in the European Union (EU), including 47% fungicides and 37% insecticides. “Pesticide residues in pet food pose potential risks to animal health, yet their occurrence and dietary exposure in companion animals remain largely unexplored,” the authors state. They continue: “To our knowledge, this is one of the first comprehensive investigations assessing both pesticide prevalence and potential dietary […]

(Beyond Pesticides, March 3, 2025) When the United Nations (UN) adjourned the fifth session of the Intergovernmental Negotiating Committee to develop an international legally binding instrument on plastic pollution, including in the marine environment, Inger Andersen, executive director of the United Nations Environment Programme (UNEP), said, “The world’s commitment to ending plastic pollution is clear and undeniable.” She continued, “Here in Busan [Korea], talks have moved us closer to agreeing on a global legally binding treaty that will protect our health, our environment, and our future from the onslaught of plastic pollution.” In March 2022, the UN Environment Assembly adopted UNEA Resolution 5/14 entitled “End plastic pollution: Towards an international legally binding instrument.”  With the Trump Administration shutting down environmental programs and exiting from collaborative international environmental agreements, the work of the world community has taken on elevated importance, given the urgency of health, biodiversity, and environmental crises; so, too, has the work going on at the state level and in local communities across the United States. The interconnectedness of the pesticide and plastic problems was brought into focus recently with a scientific review of articles showing elevated pesticide hazards linked to plastic contamination. A literature review in Agriculture, covering over 90 scientific […]

(Beyond Pesticides, February 6, 2025) Months after publishing a June 2024 study regarding concentrations of pesticides discovered in legal (and illegal) cannabis products in California, the Los Angeles Times has released a follow-up exposé highlighting extensive pesticide contamination, including from “hidden” pesticides that regulators have not monitored. The authors conclude that in California’s legal weed market, over half of available smoking products are found to contain hidden chemicals—toxic pesticides present in products but not regulated or monitored by state authorities. Since 2015, Beyond Pesticides has laid out health, safety, and environmental concerns related to the contamination of cannabis by pesticides (and fertilizers) alongside an imperative need to mandate an organic systems approach to cannabis production. Yet ten years later, it appears nationally that California state regulators are alone in moving forward in 2021 with state organic cannabis certification. There are other marketplace-based cannabis certification labels that require comparable organic certification practices (see Beyond Pesticides reporting here and here). For more information, please see past Pesticides and You reporting here and here. The Los Angeles Times analyzed the results from state licensed laboratory testing of more than 370 legal cannabis products, representing 86 brands. In addition to the 66 chemicals required […]
