(Beyond Pesticides, May 18, 2021) Organic meat is far less likely to be adulterated with multi-drug resistant bacteria (MDRB) than conventional meat, according a study published earlier this month in Environmental Health Perspectives. The research by experts at John Hopkins Bloomberg School of Public Health is the latest news on the health and safety benefits of choosing organic, which prohibits the regular use of risky antibiotics, for oneâs food purchases. Scientists indicate that contaminated foods pose serious dangers for consumers, public health, and the economy at large. “The presence of pathogenic bacteria is worrisome in and of itself, considering the possible increased risk of contracting foodborne illness,” senior author Meghan Davis, PhD, associate professor at the Bloomberg School said. “If infections turn out to be multidrug resistant, they can be more deadly and more costly to treat.” To determine the level of contamination in various packaged meats, scientists turned to the National Antimicrobial Resistance Monitoring System (NARMS), a collaborative program between the U.S. Centers for Disease Control and Prevention, the U.S. Food and Drug Administration (FDA), and the U.S. Department of Agriculture. For a five year period spanning 2012-2017, NARMS collected meat products (chicken breast, ground beef, ground turkey, and […]

(Beyond Pesticides, April 29, 2021) Glyphosate-based herbicides (GBHs) are incompatible with sustainable agriculture goals, according to a recent scientific literature analysis by scientists at Tufts University, Massachusetts. Glyphosate is the most commonly used pesticide active ingredient worldwide, appearing in many herbicide formulas, including Bayerâs (formerly Monsanto) RoundupTM. The use of this chemical has been increasing since the inception of crops genetically modified to tolerate glyphosate. However, studies demonstrate glyphosate is the main contributor to human, biotic, and ecosystem harms as toxicities from herbicides are now double what it was in 2004. The National Academy of Sciences identifies four goals of sustainable agricultureâproductivity, economics, environment, and social well-being for future generations. However, pesticides like glyphosate are ubiquitous in the environment, putting the health, economy, and food/resources for future generations at risk. Therefore, research like this is vital for understanding how chemical use can undermine sustainable agriculture goals to protect humans, animals, and environmental health. Researchers note, â[W]hether or not GBHs are viewed as essential or unessential to contemporary agriculture, and notwithstanding their role in non-tillage agriculture, this study shows that glyphosate-based herbicides do not reach the bar of agricultural sustainability, with respect to humans and the environment, making the system they are part of unsustainable.â Researchers thoroughly examined […]

(Beyond Pesticides, January 26, 2021) As the world moves toward another pandemic associated with antibiotic resistance, Beyond Pesticides sued Sargento Foods, Inc. for misleading its customers with product label claims of âno antibiotics,â which is false according to the complaint. The lawsuit alleges that Sargentoâs cheese products are made with milk from cows raised with antibiotics and that antibiotics can be found in some of the companyâs finished food.   The use of antibiotics in agriculture is contributing to a âlooming potential pandemicâ worldwide, resulting from a ârise in multidrug-resistant bacterial infections that are undetected, underdiagnosed, and increasingly untreatable, [which] threatens the health of people in the USA and globally,â according The Lancet, a prestigious medical journal, in September. The World Health Organization has declared that, âAMR [antimicrobial resistance] is one of the top 10 global public health threats facing humanity.â The primary contributors to AMR identified in the scientific literature are antibiotic uses in agriculture and overuse in medicine. âThis lawsuit is motivated by the urgent need to transition away from practices in agriculture that are dependent on antibiotics, advance organic farm management, and avoid new deadly pandemics,â said Jay Feldman, executive director of Beyond Pesticides. âOne way to do this is to […]

(Beyond Pesticides, October 5, 2020)  Another example of trading health and environmental protection for the support of special interests, EPA announces the misleading and fraudulently named, âEPA Supports Technology to Benefit America’s Farmers.â This time, EPA announces plans to âstreamline the regulation of certain plant-incorporated protectants (PIPs).â Named to sow confusion, PIPs are plants engineered with pesticides in them. PIPs are known in general for two problems arising from incorporating pesticidal ingredients into crops: residues that cannot be washed off and production of crop-eating insects that are resistant to the incorporated pesticide that blankets the agricultural landscape. Tell Congress that EPA needs to listen to science, not pesticide manufacturers and biotech companies that are causing problems for farmers and the environment. This time, EPA is proposing to exempt from regulation certain PIPs created by biotechnological techniques that are cisgenic (using genes derived from sexually compatible species), such as CRISPR. The distinction that EPA seeks to make between cisgenic plants and transgenic plants (in which the gene of interest may come from any species) is not supported by science. In fact, cisgenic techniques make use of genetic material other than the targeted genes, and that may come from species that are not […]

(Beyond Pesticides, July 8, 2020)Â Efforts to control the transmission of malaria are encountering a big, though predictable, problem: the mosquitoes that transmit malaria are developing resistance to at least five of the insecticides that have been central to limiting transmission of the disease. A study released in late June reveals a dramatic increase in resistance to pyrethroid insecticides and DDT across sub-Saharan Africa. This signals the failure of a mainstay chemical approach to the spread of malarial mosquitoes; this same problem â resistance â is happening with chemical management of agricultural pests and weeds, and with antibiotics to treat human bacterial infections. This study underscores a point Beyond Pesticides has made repeatedly: resistance to pesticides (whether insecticides, herbicides, biocides, fungicides, or medical antibiotics) is nearly inevitable. The solution to containing the spread of malaria lies not in the use of more and different chemicals, but in nontoxic approaches that respect nature and ecological balance. Malaria is a sometimes deadly disease caused by female Anopheles mosquitoes infected with any of four varieties of the Plasmodium parasite. The disease kills roughly 400,000 people annually, with half that mortality in sub-Saharan Africa. The U.S. sees approximately 2,000 cases of malaria annually, primarily in […]

(Beyond Pesticides, June 17, 2020) The June 3 decision in a high-profile âdicamba caseâ â against the U.S. Environmental Protection Agency (EPA) and for the plaintiffs, a coalition of conservation groups â was huge news in environmental advocacy, agriculture, and agrochemical circles. The federal Ninth Circuit Court of Appeals vacated EPAâs 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 âexisting stocksâ 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 agencyâs mission â âto protect human health and the environment.â According to Beyond Pesticides, EPA should never permit continued use of a dangerous pesticide once that compoundâs […]

(Beyond Pesticides, May 26, 2020) Across the pond, the European Commission (EC) has announced plans to protect biodiversity and build a more sustainable food system, and identified the reduction of pesticide use and the expansion of organic agriculture as pillars of the scheme. The EC expects that the initiative, which will require EU member statesâ endorsement, will advance progress on the EU goal of eliminating greenhouse gas emissions by 2050, given that 10% of emissions arise from the agricultural sector. The ECâs goals are important and laudable, but Beyond Pesticides is clear: reduction of pesticide use in service of them is not an adequate strategy to ensure long-term success. Genuine success requires the elimination of the use of synthetic chemical pesticides, fertilizers, and other toxic inputs, and the transition to agricultural and land management systems that work with nature, rather than fight against it. Regenerative, organic practices are the path to a livable future, according to Beyond Pesticides. The EC, which is the executive branch of the EU, expects its plan to reduce use of pesticides by 50% by 2030; reduce use of antimicrobial chemicals, including antibiotics, in fish and animal farming by 50%; dedicate a minimum of 25% of arable […]

(Beyond Pesticides, May 21, 2020) Use of the herbicide dicamba increases humans’ risk of various acute and chronic cancers, according to research published in the International Journal of Epidemiology by the National Institutes of Health (NIH). Many pesticides are âknown or probableâ carcinogens (cancer-causing agents), and their widespread use only amplifies chemical hazards, adversely affecting human health. However, past research lacks comprehensive information regarding human health effects associated with long-term pesticide use. This study highlights the significant role that long-term research plays in identifying potential health concerns surrounding registered pesticides, especially as the Environmental Protection Agency (EPA) plans to reaffirm its decision to allow dicamba use on genetically engineered (GE) crops. Nathan Donley, Ph.D., a scientist with the environmental health program at the Center for Biological Diversity, comments: âThis sweeping study exposes the terrible human cost of the EPAâs reckless decision to expand the use of dicamba. [âŚ]For the EPA to approve widespread use of this poison across much of the country without assuring its safety to people and the environment is an absolute indictment of the agencyâs persistent practice of rubber-stamping dangerous pesticides.â Dicambaâa benzoic acid chemical that controls broadleaf weedsâis one of the most widely applied herbicides in corn production. As a result of weed resistant to […]

(Beyond Pesticides, April 30, 2020) Chemical-intensive farming of crops for animal fodder powers the global market for highly hazardous pesticides (HHPs), according to data analyzed by Unearthed, and the Swiss NGO Public Eye. Animal fodder production not only intensifies global pollution, but it also increases pesticide exposure and degrades human, animal, and environmental health. This data analysis supports advocates advancing pesticide policies to eliminate HHPs by identifying which toxic chemicals lead global pesticide sales. However, it will take more than eliminating the worst chemicals to address the impending biodiversity collapse and the climate crisis, according to experts who point to the need for an urgent shift to organic land and agricultural management practices. United Nationsâ (UN) special rapporteur on toxic substances and human rights, Baskut Tuncak, says, âThere is nothing sustainable about the widespread use of highly hazardous pesticides for agriculture. Whether they poison workers, extinguish biodiversity, persist in the environment, or accumulate in a motherâs breast milk, these are unsustainable, cannot be used safely, and should have been phased out of use long ago.â Unearthed and Public Eye investigated over $23 billion in global pesticide market sales to determine the proportion of pesticides considered highly hazardous by the Pesticide Action Networkâs […]

(Beyond Pesticides, April 7, 2020) Last week, the U.S. Environmental Protection Agency (EPA) registered a carcinogenic herbicide for new uses without following the required public notification and comment process, the Midwest Center for Investigative Reporting (MCIR) reports. The chemical in question, isoxaflutole, is a broadleaf weedkiller that can now be applied to genetically engineered (GE) soybeans in half of U.S. states. Health and environmental groups are outraged by EPAâs furtive move, accusing the agency of colluding with the pesticide industry. âClearly no one from the public health community knew about this because no one commented,â said Nathan Donley, PhD, of the Center for Biological Diversity to MCIR. âYet there was all these industry comments, all these positive comments. Someone was tipped off that this docket had been opened. One side was able to comment, the other wasnât.â Without public notification, only 54 comments were received. In its decision document, the agency touted how most of the input âwere generally in favor of the decision to register the new use.â When questioned about its move, EPA simply told MCIR that it ârequested public comment on the proposed registration decision.â The Federal Register provides the public notice of a proposed rulemaking by […]

(Beyond Pesticides, January 7, 2020) It may seem peculiar at first sight, but painting zebra stripes on domestic cattle has the potential to significantly reduce the livestock industryâs use of toxic pesticides, according to research published last year by Japanese scientists at the Aichi Agricultural Research Center in Nagakute, Japan. Each year, farmers spend an estimated $1.6 billion on pesticides in the livestock industry, while biting flies cause over $2 billion of economic loss. This clever example of applied ecology could change those numbers with the added benefit of a safer environment. Â Â While long considered a mystery, the science is now generally in agreement that zebras developed their stripes in order to confuse and ward off biting flies and the various ailments that can be passed on by the pests. While some cow breeds were developed with spotted patterns that may confer some fly deterrence, researchers used mono-colored Japanese Black cows to test their hypothesis. Six cows were separated into one of three groups: white and black stripes, black stripes, and an unpainted control. Stripes were painted with a water-based lacquer. The cows were observed starting 30 minutes after the paint was applied and allowed to air out. For […]

(Beyond Pesticides, September 20, 2019) The actual utility of pesticides to achieve their purported goals is an under-recognized failing of the regulatory review of pesticide compounds for use. A study published in Scientific Reports now exposes the faulty assumptions underlying the use of neonicotinoids â the most widely used category of insecticides worldwide. The study demonstrates that use of neonicotinoids (neonics) to treat seeds â a very common use of these pesticides â actually provides negligible benefits to soybean farmers in terms of yield and overall economic benefit. The U.S. Environmental Protection Agency (EPA) should take notice, and consider that efficacy ought to have a role in the agencyâs evaluation of pesticides for registration. Neonicotinoids are systemic pesticides that move through a plantâs vascular system and are expressed in pollen, nectar, and guttation droplets (drops of sap exuded on the tips or edges of leaves of some vascular plants). They can also persist in the environment â in soil and water â for extended periods. Neonics are applied to seed, as well as to crop soils and to plant foliage. Corn and soybean seed treatments represent the largest uses of neonics in the U.S.: for somewhere between 34% and 50+% […]

(Beyond Pesticides, July 2, 2019) German cockroaches, the bane of many apartment-dwellers throughout the U.S., can rapidly develop cross-resistance to insecticides they have never been exposed to, according to researchers from Purdue University. âThis is a previously unrealized challenge in cockroaches,â said Michael Scharf, PhD, whose findings were published in the journal Scientific Reports. âCockroaches developing resistance to multiple classes of insecticides at once will make controlling these pests almost impossible with chemicals alone.â In the face of pesticide resistance, integrated measures that focus structural, mechanical, and cultural pest management practices must become standard practice for this notorious pest. Dr. Scharf and his colleagues began their study at two separate housing complexes in Indianapolis, IN and Danville, IL. Prior to the study, researchers pre-treated a subset of cockroaches in each building, and selected five insecticides out of 14 commercially available. These insecticides â abamectin, pyriproxyfen, thiamethoxam, lambda-cyhalothrin, and boric acid, were used because cockroaches had already developed significant resistance to others tested, mostly synthetic pyrethroids. Pre-treatment applications of synthetic pyrethroids revealed over 80% of cockroaches surviving. For the insecticides left with any level of efficacy, researchers established three separate treatment approaches, and stuck with it for six months, with one […]

(Beyond Pesticides, April 25, 2019)Â As reported by Mother Jones, the New York Times (NYT) published, on April 6, a distressing report about a deadly fungus that has been advancing steadily across the world during the past five years. Candida auris is an emerging fungal pathogen that threatens those with compromised or immature immune systems, such as infants, the elderly, people taking steroids for autoimmune disorders, diabetics, those undergoing chemotherapy, and even smokers. Nearly half of those who contract a C. auris infection die within 90 days. One of the factors making this fungus so deadly is that it has developed resistance to existing antifungal medicines, with 90% of infections resistant to one drug, and 30% to two or more. As is true for resistant bacteria, culprits in C. aurisâs development of resistance may be the overuse of antifungal medications in health care and overreliance on fungicides in agriculture. The Centers for Disease Control and Prevention (CDC) has added C. auris to its list of pathogens considered âurgent threats.â It is an âemerging fungal pathogen,â meaning that the incidence of infection has been increasing across multiple countries since it was first recognized in 2009 in Japan (although a different strain had […]

(Beyond Pesticides, January 10, 2019) The Trump administration is opening the floodgates to allow widespread use of antibiotics in citrus (grapefruits, oranges and tangerines) production, expanding on an emergency use decision it made in 2017. The public has an opportunity to comment on the widespread use of streptomycin by January 19, 2019. You can comment on the federal governmentâs public comment page (regulations.gov) by leaving a comment opposing any additional use of antibiotics in food production during a national and international crisis of deadly disease resistance to antibiotics. You can copy Beyond Pesticidesâ prepared comment below and add your own concerns. Strikingly, the decision allows for up to 480,000 acres of citrus trees in Florida to be treated with more than 650,000 pounds of streptomycin per year, and 23,000 citrus acres in California will likely be treated annually. The two approved antibacterial chemicals to be used as a pesticide in citrus production are streptomycin and oxytetracycline. These uses were permitted by the U.S. Environmental Protection Agency (EPA) under an emergency exemption in May, 2017, allowing residues of antibiotics in Florida orange juice, for the antibiotics streptomycin and oxytetracycline âallowing their use for a bacterial disease, citrus greening (Candidatus Liberibacter asiaticus (CLas) bacterium that causes Huanglongbing), […]

(Beyond Pesticides, January 2, 2019) The âindoor microbiomeâ of yoga studios and other athletic facilities often contain significant levels of antibacterial chemicals like triclosan, which show up in dust and breed antibiotic resistance, according to research published last month in the journal mSystems. Triclosan may be banned from hand soaps, but its continued use in a myriad of other products, from disinfectant sprays to impregnated clothing, yoga mats, and other work-out equipment makes it difficult to avoid this now-ubiquitous chemical. This is a public health concern because these antibacterial or antimicrobial chemicals are link to antibiotic-resistant bacteria. Antibiotic resistance kills over 23,000 people each year, according to the Centers for Disease Control and Prevention (CDC). In addition to the CDC, the World Health Organization has cited this escalating problem as become one of the biggest public health challenges of our time. Many people may suspect their gym or yoga study is not a germ-free location, but attempts to address these germs through antibacterial sprays or impregnated yoga mats and other surfaces, may be exacerbating the issueâdoing much more harm than good. The continued detection of triclosan and its impacts at new and unexpected locations are feeding renewed calls for a complete ban on […]

(Beyond Pesticides, December 21, 2019) A study at the University of Maine (UMaine) finds that adding blackberry leaf litter in stormwater catch basins creates an âecological trap,â enticing mosquito females to lay eggs in sites unsuitable for larvae survival. Employing this new and incredibly viable âattract-and-killâ tool for mosquito control shows potential for preventing the breeding of mosquitoes that may carry insect-borne diseases, especially in urban environments. Stormwater catch basins regularly accumulate leaf litter, which serve as habitat for the mosquito species Culex pipiens (Cx. Pipiens) that may carry West Nile virus. Previous University of Maine research discovered decomposing leaf litter from Amur honeysuckle (Lonicera maackii) and common blackberry (Rubus allegheniensis) produces chemical compounds that attracts and stimulates Cx. Pipiens female to oviposit, or lay eggs. Investigating the attractiveness and lethality of varying catch basin conditions to mosquitoes, researchers hypothesized that blackberry leaf litter could be shown to be lethal to developing mosquito larvae, and, therefore, act as a natural ecological trap for Cx. Pipiens. Five varying treatments were applied to a total 50 catch basins. Treatments included (1) all debris dredged weekly throughout the duration of the study, (2) no change to debris naturally occurring in catch basins, (3) […]

(Beyond Pesticides, November 27, 2018) The U.S. Environmental Protection Agency (EPA) ignored the input of an expert weed scientist on the controversial herbicide dicamba, bending to Bayerâs Monsanto and the pesticide industry, according to emails obtained by the Arkansas Democrat and Chronicle (ADC) through a Freedom of Information Act request. The scandal centers on the recent re-approval of the pesticide, a highly volatile and drift-prone herbicide that has become a serious problem for many farmers and state regulators. As top-level EPA officials continue to work with industry to subvert their own agencyâs scientific findings, more and more consumers are moving to organic products in order avoid the pesticide risks government regulators ask consumers to accept. Emails ADC received indicate that Jason Norsworthy, PhD, a weed scientist with the University of Arkansas, worked closely with Bayerâs Monsanto in conducting field trials this past summer, but found high volatility and drift of the companyâs new dicamba-based herbicide XtendiMax. The product was developed in the face of widespread resistance to glyphosate-based herbicides in genetically engineered (GE) farm fields. However, recent accounts from farmers in the south and midwest indicate that, not only is the switch to dicamba unhelpful in eliminating drift and reversing escalating weed resistance, its […]

(Beyond Pesticides, November 21, 2018) A study published last month in the Journal of Apicultural Research finds significant numbers of U.S. honey bees at risk after exposure to hazardous synthetic pesticides intended to control mosquitoes. With many beekeepers rarely given warning of insecticide spraying, researchers say the risk of losing colonies could increase. Advocates say fear of Zika and other mosquito-borne illnesses could result in counterproductive and reactionary insecticide spraying that will add further stress to managed and native pollinators already undergoing significant declines. Researchers aimed to determine whether neighboring honey bee colonies could be similarly affected by aerial insecticide spraying. To calculate the percentage of colonies that could be affected, density of honey bee colonies by county was compared with projections of conditions thought to be prone to regional Zika virus outbreaks. Researchers found 13 percent of U.S. beekeepers at risk of losing colonies from Zika spraying. In addition, it was determined that many regions of the U.S. best suited for beekeeping are also those with favorable conditions for Zika-prone mosquitoes to proliferate. These regions include the southeast, the Gulf Coast, and California’s Central Valley. â[Considering] all the threats facing bees,â says study lead author Lewis Bartlett of the […]

(Beyond Pesticides, November 16, 2018)Â Pesticides and biocides used to control bacterial infections in humans and weeds and pests in agriculture are surpassing âplanetary boundariesâ within which human civilization can continue to rely on these biocides, according to a review by an international team of scientists working on the Living with Resistance project. While the study reinforces the role of susceptible populations in managing resistance, it fails to distinguish essential differences between antibiotic resistance and resistance to pesticides that is identified by Beyond Pesticides. The study focuses on six different forms of resistance. Researchers looked at antibiotic resistance in gram negative bacteria (such as E. coli, P. aeruginosa, Salmonella) and gram positive bacteria (such as S. aureus, Clostridium) separately, due to their divergent resistance mechanisms. Pesticide resistance was divided among herbicides in general, herbicide resistant crops, insecticides in general, and genetically engineered (GE) crops that produce their own insecticide. Resistance to antibiotics and pesticides are similar in that they are both evolved responses to substances toxic to the organism. However, lumping them together in evaluating their importance to human health and survival does not recognize important differences in context. âWithout new approaches, going to hospital in the future will increasingly become […]

(Beyond Pesticides, November 8, 2018) Two months after publishing its first series of tests, part two of an Environmental Working Group (EWG) study finds residues of Roundupâs active ingredient, glyphosate, in all General Millsâ Cheerios and PepsiCoâs Quaker Oats products sampled. Health advocates are expressing concern about the consequences of chronic glyphosate exposure, and say U.S. federal agencies must limit the herbicideâs use on oat-based breakfast foods regularly marketed to children. In addition, organic itself is under threat, as chemical-intensive management practices undermine the future of the growing organic movement. In this second round of testing, EWG scientists purchased products around San Francisco and Washington DC. 28 samples of conventional and 16 samples of organic oat products were collected. Approximately 300 grams of each General Mills and PepsiCo product were packaged and shipped to Anresco Laboratories, in San Francisco. Detected glyphosate residues were compared to EWGâs own health benchmark of 160 parts per billion (ppb). This benchmark is based on risks of lifetime exposure and what EWG scientists consider allowable and protective of childrenâs health with an adequate margin of safety. EWGâs results detected glyphosate residues in all 28 samples of conventionally grown oat products. The vast majority (all but two) […]

(Beyond Pesticides, October 16, 2018) Bacteria exposed to widely used herbicides like Roundup develop antibiotic resistance 100,000 times faster than average, according to new research published by New Zealand scientists in PeerJ. The results have ominous implications for the modern worldâs ability to avert a post-antibiotic era. Even if new antibiotics are discovered, or existing compounds used more judiciously, scientists say that will not be enough to prevent the ongoing crisis – the world is also confronting bacterial exposure to herbicides and other non-antibiotic agents that have the ability to rapidly induce resistance. âHerbicides are among the most widely used and dispersed manufactured products on Earth. Some form of exposure for people, pets and livestock can be routinely expected,â study author Jack Heinemann, PhD, told Newsweek. âMeanwhile, antibiotics are used at high rates particularly on people, pets and livestock. Therefore, the combination of exposures for bacteria that live on us is all but guaranteed.â This current round of research by Dr. Heinemann and his team is the outgrowth of previous studies (1, 2) that established the ability of common herbicides to induce antibiotic resistance in strains of pathogenic bacteria Salmonella eterica and Escherichia coli. Now, the scientists are drilling into […]

(Beyond Pesticides, August 2, 2018) Weed scientists from the University of Missouri (UM) have just published evidence of a water hemp population resistant to six different herbicides. The study is sending shock waves throughout the chemical-intensive agricultural community, particularly in light of the plant’s resistance to 2,4-D. In its reporting on the study, KTIC Rural Radio begged the question, âIf weâre already seeing 2,4-D resistance now, what will happen when use of the herbicide becomes even more commonplace?â KTIC is referring to the impending commercialization of products like Enlist Duo, developed by DowDupont in an attempt to address widespread weed resistance to glyphosate. Enlist Duo is an herbicide containing both glyphosate and 2,4-D, and is intended to be sprayed only on crops genetically engineered (GE) to tolerate exposure to both chemicals. However, with growing reports like this, many farmers may begin to rethink their approach. In 2014, a farmer contacted UM indicating that water hemp was not responding to 2,4-D during a regular âburndownâ the farmer conducted before planting a new crop. (Chemical-intensive farmers will often use a synthetic herbicide to clear their field for new plantings.) The farmer had also used other herbicides, fomesafen and glyphosate, in this process […]
