(Beyond Pesticides, December 22, 2020) Opening arguments and evidence were filed by a coalition of farmworkers, farmers, and conservationists last week in litigation challenging the U.S. Environmental Protection Agency’s (EPA) re-approval of glyphosate, best known as the active ingredient in Monsanto’s “Roundup” pesticides. The lawsuit charges that the Trump Administration unlawfully ignored cancer risks and ecological damage of glyphosate.  Represented by the Center for Food Safety (CFS), plaintiffs, including the Rural Coalition, Farmworker Association of Florida, Organización en California de Lideres Campesinas, and Beyond Pesticides, filed the federal lawsuit in the Ninth Circuit Court of Appeals in March. The groups seek to have the pesticide prohibited from use or sale because of its unlawful approval. “Farmworkers are on the frontlines of nearly every health and environmental crisis, from the COVID-19 pandemic to climate change, and are particularly at risk of health impacts from pesticide spraying,” said Amy van Saun, senior attorney at CFS. “EPA failed these essential workers. It rejected evidence that glyphosate causes cancer and entirely failed to assess the main way people are exposed at work, through their skin.” The court filing includes volumes of evidence showing how EPA ignored glyphosate’s health risks, including cancer risks, to farmworkers and farmers exposed during spraying. The evidence […]

(Beyond Pesticides, December 4, 2020) Amid the maelstrom of national political news related to the recent election, and the Trump administration’s upcoming exit, comes a release of the Environmental Protection Agency’s (EPA’s) draft biological evaluation (BE) of glyphosate. The assessment indicates that use of this ubiquitous herbicide likely threatens nearly every animal and plant species on the U.S. list of threatened and endangered species — 93% of them, in fact. Chemical and Engineering News reports that the EPA announcement was made public only a few days after the agency also reported that atrazine (another commonly used and toxic herbicide) probably harms more than half of those species. Given the Trump EPA’s eagerness, during the past four years, to serve industry interests rather than protect human health, biodiversity, and functional ecosystems, the timing of this released evaluation during the so-called “lame duck” period is puzzling. Glyphosate is the active ingredient in many herbicides, including RoundupTM, Monsanto’s (now Bayer’s) ubiquitous and widely used weed killer; it is very commonly used with genetically modified companion seeds for a variety of staple crops, as well as for weed control on managed landscapes. These seeds are genetically engineered to be glyphosate tolerant. Glyphosate-based herbicides are the most […]

(Beyond Pesticides, November 18, 2020) The herbicide atrazine is likely to adversely affect over half of endangered species listed in the United States, according to a report released by the U.S. Environmental Protection Agency (EPA) as part of a legal agreement with the Center for Biological Diversity (CBD). Based on both adverse human health and environmental threats, Beyond Pesticides joined with Center for Food Safety, CBD, and other public-interest groups in October to sue EPA over its decision to reapprove atrazine, an endocrine-disrupting herbicide banned across much of the world. These actions follow the agency’s recent reapproval of atrazine, which reduced a number of safeguards for public health and the environment, and it’s enactment of rules that limit endangered species reviews.  See (Lawsuit Challenges EPA Reapproval of Endocrine-Disrupting Pesticide Atrazine: Agency Slashes Protections for Children, Waterways.) Although advocates are hopeful that the next administration will shift toward an EPA that lives up to its namesake, there is considerable ground to make up. Atrazine is an herbicide that disrupts the endocrine system by mimicking the body’s natural hormones, binding to hormone receptors in the body. In humans, the effect can result in birth defects, damage to the reproductive system, and chronic […]

(Beyond Pesticides, October 1, 2020) A federal judge on September 24, 2020 dismissed an  environmental lawsuit seeking to reinstate a U.S. Fish and Wildlife Service (FWS) rule, killed by the Trump Administration, which banned the use of neonicotinoid insecticides, genetically engineered (GE) crops, and adopted a precautionary approach to pest management. The decision comes on the heels of a Center for Biological Diversity (CBD) analysis that reports a 34% increase in the pesticide use on U.S. national wildlife refuge acres over a two year period from 2016-2018. This analysis is an update to CBD’s 2018 report, No Refuge, which is the first of its kind to offer comprehensive details of agricultural pesticide spraying in national wildlife refuges. Wildlife refuges act as a sanctuary, providing habitat and protection essential for the survival and recovery of species nationwide. However, pesticide spraying in or around wildlife refuges threatens the survivability and recovery of species that reside there as many of these pesticides are highly toxic to human and animal health. Analyses like these are significant, especially since the globe is currently going through the Holocene Extinction, Earth’s 6th mass extinction, with one million species of plants and animals at risk of extinction. In 2012, […]

(Beyond Pesticides, August 11, 2020) Petitioners who mounted a legal challenge to the Environmental Protection Agency’s (EPA’s) registration of Enlist Duo, a relatively new and highly toxic pesticide product, recently learned of a mixed decision from the U.S. Ninth Circuit Court of Appeals in the case. The good news is that Judge Ryan D. Nelson, writing the opinion for the court, found that EPA, in registering the herbicide Enlist Duo, had failed to protect monarch butterflies, which are under consideration as a threatened species under the Endangered Species Act (ESA). On the other and disturbing hand, the court concluded that EPA registration of the product was otherwise lawful — which means that this toxic compound will for now remain on the market. As one of the plaintiffs in the case, Beyond Pesticides is adamant that this product should not be registered for use by EPA. George Kimbrell, Legal Director of Center for Food Safety and Lead Counsel for the plaintiffs, commented on the decision in the organization’s July 22 press release on the decision: “The panel majority’s unprecedented decision is contrary to controlling law and established science, and Center for Food Safety is analyzing all legal options, including seeking a full […]

(Beyond Pesticides, June 29, 2020) Bayer’s Monsanto is requesting non-regulated status for corn that will increase the use of drift-prone and toxic herbicides. This means that the planting of a new genetically engineered (GE) variety of corn, which requires substantial weed killer use, will not be restricted in any way. The syndrome of ‘more-corn, more-pesticides, more-poisoning, more-contamination’ must stop—as we effect an urgent systemic transformation to productive and profitable organic production practices. Because USDA is proposing to allow a new herbicide-dependent crop under the Plant Protection Act, the agency must, but does not, consider the adverse impacts associated with the production practices on other plants and the effects on the soil in which they are grown. Business as usual is not an option for a livable future. Sign the petition. Tell USDA we don’t need more use of 2,4-D, Dicamba, and other toxic herbicides associated with the planting of new GE corn. Bayer-Monsanto has developed multi-herbicide tolerant MON 87429 maize, which is tolerant to the herbicides 2,4-D, dicamba, glyphosate, glufosinate, and aryloxyphenoxypropionate (AOPP) acetyl coenzyme A carboxylase (ACCase) inhibitors (so-called “FOP” herbicides, such as quizalofop). Now the company wants this corn to be deregulated—allowing it to be planted and the herbicides […]

(Beyond Pesticides, June 17, 2020) The June 3 decision in a high-profile “dicamba case” — against the U.S. Environmental Protection Agency (EPA) and for the plaintiffs, a coalition of conservation groups — was huge news in environmental advocacy, agriculture, and agrochemical circles. The federal Ninth Circuit Court of Appeals vacated EPA’s 2018 conditional registration of three dicamba weed killer products for use on an estimated 60 million acres of DT (dicamba-tolerant through genetic modification/engineering) soybeans and cotton. There is, however, a related issue that accompanies this and many other pesticide cases. When EPA decides to cancel or otherwise proscribe use of a pesticide (usually as a result of its demonstrated toxicity and/or damage during litigation), the agency will often allow pesticide manufacturers to continue to sell off “existing stocks” of a pesticide, or growers and applicators to continue to use whatever stock they have or can procure. Beyond Pesticides has opposed, covered, and litigated against this practice. To greenlight predictable harm is a violation of any recognized moral code, never mind of the agency’s mission — “to protect human health and the environment.” According to Beyond Pesticides, EPA should never permit continued use of a dangerous pesticide once that compound’s […]

(Beyond Pesticides, June 12, 2020) New research finds that western monarch milkweed habitat contains a “ubiquity of pesticides” that are likely contributing to the decline of the iconic species. The research, published in Frontiers in Ecology and Evolution, provides a grim snapshot of a world awash in pesticides, and raises new questions about the U.S. regulatory process that continues to allow these toxic chemicals on to the market without adequate review and oversight. “We expected to find some pesticides in these plants, but we were rather surprised by the depth and extent of the contamination,” said Matt Forister, PhD, a butterfly expert, biology professor at the University of Nevada, Reno and co-author of the paper in a press release. “From roadsides, from yards, from wildlife refuges, even from plants bought at stores—doesn’t matter from where—it’s all loaded with chemicals. We have previously suggested that pesticides are involved in the decline of low elevation butterflies in California, but the ubiquity and diversity of pesticides we found in these milkweeds was a surprise,” Dr. Forister said. The researchers collected over 200 milkweed samples from nearly 20 different sites across the Central Valley of California, as well as from retailers that sell milkweed […]

(Beyond Pesticides, May 8, 2020) At the height of Covid-19 impacts in the Northeast U.S., Massachusetts Governor Charlie Baker (R) and Lieutenant Governor Karyn Polito (R) filed emergency legislation at the Boston State House that would, according to their April 16 press release, “help the Commonwealth more effectively combat diseases transmitted by mosquitoes, including arboviruses like Eastern Equine Encephalitis (EEE) and West Nile Virus (WNV), by authorizing a coordinated, proactive, statewide approach to mosquito control activities.” Protecting the public from such diseases is an important public health mission. However, the Governor’s bill, H.4650, represents an alarming “over-reach” that would give unitary authority to the State Reclamation and Mosquito Control Board (SRMCB) to conduct mosquito control activities, including ineffective and toxic spraying, with virtually no effective oversight or transparency. Beyond Pesticides opposes this bill, whose passage would enable use of pesticides that can have respiratory and immune impacts — increasing health risks for everyone, but especially for the many people already at higher risk from Covid-19, despite the availability of ecological management approaches that eliminate the need for toxic chemicals. H.4650, An Act to mitigate arbovirus in the Commonwealth — was promulgated in response to a Massachusetts Department of Public Health […]

(Beyond Pesticides, April 3, 2020) In mid-March, the Environmental Protection Agency (EPA) rolled out new rules for “biological evaluations” — assessments of pesticide risks to endangered plant and animal species that are supposed to be protected under the Endangered Species Act (ESA). The agency’s press release announcing the change is misleadingly titled: “Trump Administration Takes Major Step to Improve Implementation of the Endangered Species Act.” But as the Center for Biological Diversity (CBD) reports, the “revised methods for assessing pesticide risks . . . will allow widespread harm to most of the nation’s most endangered plants and animals.” Beyond Pesticides reviewed the status of pesticide threats to endangered species in November 2019 and provides ongoing coverage of the issue. ESA requires EPA to conduct biological evaluations (BEs) of pesticides to assess their impacts on listed (endangered and threatened) species and their critical habitats. EPA’s new “Revised Method” ignores many of the ways that protected species are commonly hurt or killed by pesticides, and allows the continued marketing and use of pesticides without sensible constraints that would protect those species. CBD cites two examples of ignored impacts: downstream impacts of pesticide runoff into waterways from treated farmland, and the loss of […]

(Beyond Pesticides, March 31, 2020) Adding to the widespread and problematic use of neonicotinoid pesticides as seed treatments, a recent study published in BioScience finds that there are significant knowledge gaps among some farmers about the seeds they are planting. The research indicates that those gaps contribute to underreporting of accurate data on the use of pesticide-coated (often with neonicotinoid pesticides) seeds — because farmers may not know what pesticides are on the seeds they plant. Pennsylvania State University reports on the study, in Phys.org, saying, “This lack of data may complicate efforts to evaluate the value of different pest management strategies, while also protecting human health and the environment.” Beyond Pesticides advocates for widespread adoption of organic, regenerative systems and practices that precludes the use of such pesticides.  The research was conducted by a team of scientist from around the U.S., led by Claudia Hitaj, PhD, of the Luxembourg Institute of Science and Technology, and former economist at USDA’s Economic Research Service. In the Phys.org coverage of the study, assistant professor of epidemiology and crop pathology at Penn State, Paul Esker, PhD, notes that this lack of farmer knowledge can lead to overuse of pesticides, which would increase the already considerable risks […]

(Beyond Pesticides, March 23, 2020) Ignoring science to side with Monsanto/Bayer, EPA has repeatedly failed to assess glyphosate’s impacts on public health and endangered species. Last week, a broad coalition of farmworkers, farmers, and conservationists, filed a federal lawsuit against the Environmental Protection Agency (EPA) over its January 2020 re-approval of the pesticide glyphosate, best known as the active ingredient in Monsanto’s Roundup pesticides. With Center for Food Safety (CFS) serving as legal counsel, the suing organizations are  Beyond Pesticides, the Rural Coalition, Organización en California de Lideres Campesinas, and the Farmworker Association of Florida. While EPA defends glyphosate, juries in several cases have found it to cause cancer, ruling in favor of those impacted by exposure. Glyphosate formulations like Roundup are also well-established as having numerous damaging environmental impacts. After a registration review process spanning over a decade, EPA allowed the continued marketing of the pesticide despite the agency’s failure to fully assess glyphosate’s hormone-disrupting potential or its effects on threatened and endangered species. The review began in 2009, has already taken 11 years, without a full assessment of the widespread harmful impacts on people and the environment in that time period. “EPA’s half-completed, biased, and unlawful approval sacrifices the […]

(Beyond Pesticides, March 17, 2020) The number of monarch butterflies overwintering in Mexico is down 53% from last year, according to a count conducted by World Wildlife Fund (WWF) Mexico. While WWF indicates the decline was expected due to unfavorable weather conditions during the species southward migration, other environmental groups are raising red flags. “Scientists were expecting the count to be down slightly, but this level of decrease is heartbreaking,” said Tierra Curry, a senior scientist at the Center for Biological Diversity. “Monarchs unite us, and more protections are clearly needed for these migratory wonders and their habitat.” WWF’s count found that monarchs occupied seven acres this winter, down from 15 acres last year. Reports indicate that 15 acres is a minimum threshold needed to prevent a collapse of the butterfly’s migration and possible extinction. This was the goal stated by the 2015 White House Pollinator Task Force, which the current administration is failing to see through. While weather conditions play an important role in monarch migration from the U.S. and Canada south to Mexico, the species is under threat from a range of environmental factors. Monarchs depend on milkweed plants to lay eggs, and monarch caterpillars feed solely on […]

(Beyond Pesticides, January 17, 2020) In Brussels, the European Commission (EC) has just decided not to renew approval of the neonicotinoid pesticide thiacloprid, citing both environmental and health concerns related to use of and exposure to the pesticide. The decision was approved by a majority of European Union (EU) governments last fall, after the EC had made the proposal to them. The EC based that proposal on findings of the European Food Safety Authority (EFSA) published in January 2019, which highlighted concerns about toxicity to humans and high concentrations in groundwater. European Commissioner for Health and Food Safety Stella Kyriakides commented, “There are environmental concerns related to the use of this pesticide, particularly its impact on groundwater, but also related to human health, in reproductive toxicity.” The current EU use approval for thiacloprid products expires on April 30, 2020. The EC decision — functionally, a ban — means that farmers will need to turn to other means to deal with the primary thiacloprid targets in agriculture, aphids and whiteflies. Beyond Pesticides and many organic agricultural resources advocate for widespread adoption of organic, regenerative systems and practices. Such systems may include management features such as mechanical and biological controls, trap crops, natural […]

(Beyond Pesticides, January 13, 2020) Birds are facing an existential crisis. Three billion birds have disappeared since 1970. Two out of three birds are threatened by climate change. In spite of this crisis, our nation’s most important bird protection law, the Migratory Bird Treaty Act (MBTA) is being weakened by the Trump Administration’s Department of the Interior. Ask your U.S. Representative to support and cosponsor the Migratory Bird Protection Act. Thank those who are already cosponsors. Songbirds Threatened. The poisonous farm fields that migratory birds forage reduce their weight, delay their travel, and ultimately jeopardize their survival, according to “A neonicotinoid insecticide reduces fueling and delays migration in songbirds,“ published in the journal Science. Like their effects on insect pollinator populations, neonicotinoid insecticides generally do not cause acute poisoning and immediate death, but instead precipitate a cascade of sublethal impacts reducing their fitness in the wild. As the authors told Environmental Health News, the study is a call not simply to ban neonics or one class of chemical, but to change the entire farming system toward more sustainable bird and bee-friendly practices. Bird Habitat Threatened in Arkansas. A citizen science monitoring project of Audubon Arkansas found evidence of contamination from the weed killer dicamba far […]

(Beyond Pesticides, December 19, 2019) Identifying ongoing risk to endangered species, the environmental group Center for Biological Diversity (CBD) announced an intent to sue California pesticide regulators to cancel the registration of four rodenticides in California. The suit seeks to expand the prohibition of use by the general consumer to include agricultural users and licensed pest-control operators. The group calls for protection of the endangered San Joaquin kit foxes, California condors, and 11 other endangered species from these rat poisons. Rodenticides are grouped into three categories: first-generation anticoagulants, second-generation anticoagulants, and non-anticoagulants. Both first- and second-generation anticoagulant rodenticides interfere with blood clotting in mammals and cause death from hemorrhage. Animals can be poisoned by eating the bait directly, or by consuming a poisoned animal (secondary poisoning). Secondary poisoning poses the greatest risk to wildlife. Second-generation anticoagulant rodenticides (SGARs), such as brodifacoum, bromadiolone, difethialone and difenacoum, are more likely to cause secondary poisonings because they persist in body tissue for extended periods of time. These four poisons are the focus of this lawsuit. In 2014, the California Department of Pesticide Regulation (CDPR) banned the use of SGARs for public consumers. Advocates were motivated by the need to protect children and wildlife from […]

(Beyond Pesticides, November 15, 2019) The Endangered Species Coalition has released its newest annual report on the 10 U.S. species most threatened by pesticide use, Poisoned: 10 American species imperiled by pesticides. Produced with seven of its member groups, the coalition introduces the report by noting, “Our world is awash in chemicals. We’re particularly addicted to pesticides.” It points to well-known harms, and identifies the exacerbating factors of both climate change and the Trump administration, the latter of which “denies the reality of climate change and has dramatically changed how the Endangered Species Act (ESA) is implemented, leaving vulnerable species at far greater risk.” The introduction ends on a somewhat encouraging tone, saying that previous administrations have supported record growth in organic farming — the solution to pesticides harms that Beyond Pesticides has long endorsed — and that “any administration has the power to get us back on track and away from pesticides.” Impacts on wildlife linked to pesticide exposures — including mammals, bees and other pollinators, fish and other aquatic organisms, birds, and the biota within soil — have been well documented by Beyond Pesticides, and include reproductive, neurological, renal, hepatic, endocrine disruptive, and developmental anomalies, as well as […]

(Beyond Pesticides, October 31, 2019) Last week the U.S. District Court in San Francisco ruled that the Environmental Protection Agency (EPA) must assess the risk eight toxic pesticides pose to protected organisms: atrazine, carbaryl, methomyl, and simazine as well as rodenticides brodifacoum, bromadiolone, warfarin and zinc phosphide. The plaintiffs, Center for Biological Diversity (CBD) and Pesticide Action Network North America (PANNA) asserted that EPA and its then administrator Scott Pruitt violated duties under the Endangered Species Act (ESA) by not consulting with the Fish and Wildlife Service and National Marine Fisheries Service in registering these pesticides. The history of this case extends over 8 years. Last year, the court rejected EPA’s attempts to dismiss the lawsuit. According to CBD’s press release, “Under the agreement the agency must complete assessments of four pesticides, including atrazine, the nation’s second most-used pesticide, by 2021. Assessments of four rodenticides, including the widely used rat poison brodifacoum, must be finalized in 2024.” Stephanie Parent, an attorney at the Center for Biological Diversity, said “This important step is only the start. We still have work to do to make sure the EPA addresses the harms of all pesticides, as the law requires. EPA was created after […]

(Beyond Pesticides, September 27, 2019) The U.S. Fish and Wildlife Service (USFWS) will be required to protect the habitat of the endangered rusty patched bumblebee, per a settlement with the Natural Resources Defense Council (NRDC) reached earlier this week. The bee was listed under the Endangered Species Act (ESA) in 2017, but USFWS has yet to designate the “critical habitat” for the bee where improved protections must be made to ensure its recovery. With the decline of both wild and managed pollinators throughout the U.S., action on this issue by federal agencies is sorely needed. According to NRDC, the settlement will require FWS to propose critical habitat by July 31, 2020, unless it makes a finding that habitat protections are not prudent. The Service must then finalize any habitat protections by July 31, 2021. Under ESA, FWS is required to designate the critical habitat of a listed species within one year of its listing if not included within its listing announcement. Thus, by drawing out this process, FWS is flouting this important action that will lead to real on-the-ground protections. “The U.S. Fish and Wildlife Service has violated federal law—again—by not designating critical habitat for the rusty patched bumble bee,” […]

(Beyond Pesticides, September 24, 2019) “Over increasingly large areas of the United States, spring now comes unheralded by the return of the birds, and the early mornings are strangely silent where once they were filled with the beauty of bird song,” Rachel Carson wrote in Silent Spring in 1962. New research finds that quote has held true since it was written. Over three billion birds, or 29% of 1970s abundance have been lost in North America over the last 50 years. To make these dismal determinations, scientists drew from multiple long-term bird monitoring datasets, and a network of nearly 150 weather radars that pick up and thus have recorded the trajectory of migratory birds. Long-term surveys helped scientists determine the 3 billion bird decline, while satellite data found that migratory bird abundance has declined by 9.1% since 2007. In general, 57% of bird species are in decline, with showing the largest loss. Ninety percent of all declines were within 12 bird families: American sparrows, warblers, blackbirds, larks, Old world sparrows, swallows, nightjars, swifts, finches, flycatchers, starlings, and thrushes. Only waterfowl and wetland bird species showed any increase, 13% and 56%, respectively. Ducks, geese, and raptors all improved population levels more […]

(Beyond Pesticides, September 23, 2019)  Your voice is making a difference! Last month, thousands of individuals took action through Beyond Pesticides and other environmental groups to express concern to their federal lawmakers about the Trump Administration’s assault on the Endangered Species Act (ESA). In response, U.S. Representatives Grijalva, Beyer, and Dingell in the House, and Senator Udall in the Senate have introduced the PAW and FIN Conservation Act of 2019. This law will roll back Interior Department regulations that would weaken this landmark law protecting species from extinction. Tell your member of Congress to co-sponsor the PAW and FIN Conservation Act of 2019! The PAW and FIN Act reverses rules which will: (i) weaken the consultation process designed to prevent harm to endangered animals and their habitats from federal agency activities; (ii) curtail the designation of critical habitat and weakens the listing process for imperiled species; and (iii) eliminate all protections for wildlife newly designated as “threatened” under the Act. Biodiversity is under threat in the US and throughout the world. Pollinator declines are well known, and now scientists are indicating we are in the midst of an insect apocalypse.  Declines at the bottom of the food chain are even more concerning given […]

(Beyond Pesticides, August 19, 2019) The Trump Administration has reignited the attack on the Endangered Species Act (ESA), one of the most effective environmental laws in restoring threatened and endangered species and their habitat. This time the attack is coming through regulations that undermine the letter, spirit, and intent of ESA. Ask your elected U.S. Representative and Senators to tell the Secretary of Interior that the assault on the Endangered Species Act threatens all living organisms. The new rules announced by the administration this week will: (i) weaken the consultation process designed to prevent harm to endangered animals and their habitats from federal agency activities; (ii) curtail the designation of critical habitat and weakens the listing process for imperiled species; and (iii) eliminate all protections for wildlife newly designated as “threatened” under the Act. With species declining across the globe, it is critical that we protect those already at heightened risk. An important provision of the ESA is the requirement that each federal agency that proposes to authorize, fund, or carry out an action that may affect a listed species or its critical habitat must consult with the U.S. Fish and Wildlife Service and National Marine Fisheries Service. Although many species –including the bald eagle, Florida […]

(Beyond Pesticides, June 8, 2019) Scientists studying the precipitous decline in populations of monarch butterflies are searching for causes, and pesticide use is one of the factors under their (figurative) microscopes. Purdue University entomology professor Ian Kaplan, PhD and doctoral student Paola Olaya-Arenas recently turned their attention to a poorly studied potential factor — exposure during monarchs’ larval stage to non-target pesticides on their primary host plant and food source, common milkweed (Asclepias syriaca). In Frontiers in Ecology and Evolution, the researchers report finding evidence of 14 different agricultural pesticides on milkweed near Indiana farm fields, including neonicotinoids clothianidin and thiamethoxam, the pyrethroid deltamethrin, and imidacloprid in a few samples. The research team’s primary aim was to identify and measure the range of pesticides to which monarch caterpillars might be exposed, or which they might consume, on milkweed plants in agricultural landscapes. Secondarily, they hoped to learn how pesticide presence varies with distance between milkweed plants and nearby agricultural sites. In the subject Indiana environs, where corn and soybeans are dominant crops, the study found neonicotinoid residues on milkweed, particularly those of the active ingredients in clothianidin and thiamethoxam. They note, “Although seed treatment data are no longer reported for U.S. […]
