(Beyond Pesticides, November 5, 2020) Research at the University of California San Francisco (UCSF) finds that pesticide exposure increases the risk of developing Parkinson’s disease (PD), regardless of whether disease onset is idiopathic (spontaneous) or genetic (GBA genetic risk variant). Although the exact etiology of PD remains unknown, epidemiological and toxicological research repeatedly identifies exposure to pesticides, as well as specific gene-pesticide interactions, as significant adverse risk factors that contribute to PD. Furthermore, this study, “Gene Variants May Affect PD Risk After Pesticide Exposure,” suggests that environmental triggers like occupational exposure to pesticides can prompt PD in individuals with or without the genetic precursor. This research demonstrates the importance of assessing disease etiology concerning occupational pesticide exposure, especially if disease triggers are overwhelmingly non-hereditary. Since not all individuals genetically predisposed to the disease develop PD, with only 10 to 15 percent of PD cases being genetic, government officials need to consider alternate etiological pathways that include environmental risk factors. Study researchers note, “‘Environmental exposures may have differential effects in different genotypes’ and may predispose people with PD to different symptom burden.”  Parkinson’s disease is the second most common neurodegenerative disease, with at least one million Americans living with PD and about […]

(Beyond Pesticides, October 21, 2020) Women now account for one in four agricultural jobs in the United States, and these important workers face unique challenges to their health and well-being, as outlined by a report published by Boise State University scientists. Farmworkers, often immigrants, or from communities of color, are frequently referred to as ‘invisible’, despite the essential job they perform getting food to American’s dinner tables. With their struggle and plight outside of the view of mainstream news, it is critical that U.S, residents better understand the lives they lead, and their daily obstacles, to inform how their conditions can be improved. “In this study, we tried to understand the women that we were working with what their concerns were and what their challenges were rather than coming in and just saying what we thought the concerns were,” Cynthia Curl, PhD, Associate Professor at Boise State University, told Idaho News 6 (IN6). To better assess the well-being of women farmworkers, researchers conducted mixed method data collection, through surveys, focus groups, and urinary analysis for pesticide body burden. Surveys were received from 70 Latina farmworkers, with 22 participating in focus groups and 11 in semi-structured interviews. An assessment of pesticide […]

(Beyond Pesticides, October 7, 2020) This week the Baltimore, Maryland City Council passed an ordinance restricting the use of toxic pesticides on public and private property—including lawns, playing fields, playgrounds, children’s facility (except school system property [golf courses are exempt]—following an approach similar to legislation first spearheaded by Montgomery County, MD in 2015. While the legislation, 20-0495, An Ordinance Concerning Pesticide Control and Regulation, generally limits inputs to the allowed materials under federal organic law, it provides for allowances for glyphosate by the Department of  Recreation and Parks. If signed by the Mayor, as expected, Baltimore City will become the most recent Maryland jurisdiction to exercise its authority to regulate pesticide use on private property, after a ruling of the state’s highest court. Language in the Baltimore ordinance tracks a similar framework to the Healthy Lawns Act passed in Montgomery County, Maryland. Any pesticide that is not compatible with organic land care—allowed under certified organic by the U.S. Department of Agriculture (USDA) or considered minimum risk by the U.S. Environmental Protection Agency (EPA)—is subject to the bill’s restrictions. Use can only occur under limited exceptions, such as to manage particularly invasive species, as well as health or economic threats. Bee-toxic […]

(Beyond Pesticides, October 6, 2020) Despite the rapid rise of antibiotic resistance in the United States and throughout the world, new documents find the Trump Administration worked on behalf of a chemical industry trade group to weaken international guidelines aimed at slowing the crisis. Emails obtained by the Center for Biological Diversity through the Freedom of Information Act show that officials at the U.S. Department of Agriculture (USDA) worked to downplay the role of industrial agriculture and pesticide use in drug-resistant infections. “From everything we’ve seen, it’s clear that this administration believes rolling back regulations and protecting industry profits is more important than protecting public health,” said Nathan Donley, PhD, senior scientist with the Center for Biological Diversity, to the New York Times (NYT). “But what these emails show is that the Department of Agriculture isn’t just soliciting their input. They’re seeking their approval on what the government’s position should be.” Ray McAllister, PhD, of the pesticide industry trade group Croplife America, sent an email in March of 2018 to U.S. officials, wanting to “make certain” that the United Nation’s (UN) Codex Alimentarius, a set of international guidelines and standards established to protect consumer health, made no mention of how […]

(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 25, 2020) The City of Gaithersburg, MD has chosen to opt-in to Montgomery County’s Healthy Lawns Act, restricting toxic pesticide use on public and private property. According to the local Patch, the mayor and City Council voted to adopt the law in mid-August, and it will take effect for all residents and businesses in city on December 1. Although Montgomery County passed the Healthy Lawns Act approximately five years ago, incorporated cities within the county are required to proactively opt-in to the law for it to apply within their jurisdiction. Gaithersburg is the latest, and largest city to opt-in to the county’s law, which encourages organic practices by limiting pesticide use on lawns and landscapes to products that are certified organic or considered minimum risk by the U.S. Environmental Protection Agency. In mid-June, the Town of Garrett Park also opted in to the law, according to reports. Advocates are advocating that all cities within Montgomery County adopt the law. The same group of grassroots advocates that pushed Montgomery County leaders to adopt its Healthy Lawns Act years ago is also leading the push for opt-ins. Safe Grow Montgomery, a group of concerned mothers and fathers working for […]

(Beyond Pesticides, August 13, 2020) Levels of the notorious herbicide compound glyphosate in the human body are reduced by 70% through a one-week switch to an organic diet, finds a new, peer-reviewed study published in August 2020 in the journal Environmental Research. This result emphasizes both the ubiquity of this compound in the human body, and diet as the primary source of exposure for most people. It also adds to the evidence for Beyond Pesticides’ assertions that: (1) chemical-intensive agriculture must be abandoned, for a variety of reasons that include human health, and (2) in the lead-up to a transition to organic and regenerative agriculture, consuming organic foods as much as is practicable is powerful protection from glyphosate, and from the assault of multiple chemical pesticides to which most people are exposed. Glyphosate is the active ingredient in the popular weed killer RoundupTM, which has been used intensively in the U.S. and around the world, especially during the last couple of decades. It is very commonly used on crops grown from genetically engineered (GE) companion seeds for a variety of staple crops (e.g., soybeans, cotton, and corn). These GE seeds are glyphosate-tolerant, whose attribute has allowed growers to apply the herbicide and […]

(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, July 7, 2020) One’s zip code plays an important role in the likelihood of developing Parkinson’s disease (PD), according to data published by Louisiana State University researchers in the International Journal of Environmental Research and Public Health. With genetics and exposure to agricultural pesticide use identified as the main factors affecting PD, proximity to certain cropland and its effluent had a major impact on disease risk. As with most environmentally related diseases, this study highlights the disproportionate risk and environmental racism low income, indigenous and people of color communities endure. Researchers received access to over 23,000 PD diagnoses in Louisiana between 1999 and 2012, and mapped these data by zip code. Risk was determined calculating the number of diagnoses per 10,000 people in a given zip code, based on census data. To flesh out the role agriculture was playing in PD diagnoses, additional data derived from water quality samples taken by the Louisiana Department of Health and Hospitals, and the U.S. Geological Survey pesticide use estimates were compared against reported disease incidence. Results show that certain zip codes faced significantly higher incidence of PD than others in the state. Further, “The PD high-risk areas match closely the arbor-pastoral […]

(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 4, 2020) A new, simultaneous chemical identification method has found the presence of the weed killer atrazine and 200+ other hazardous chemicals in hydraulic fracturing (fracking) wastewater or produced water, according to collaborative research published in the Journal of Separation Science by scientists at the University of Toledo (UToledo) and the University of Texas at Arlington. Although produced water is a waste product of fracking, the U.S. Environmental Protection Agency (EPA) allows many states to reuse produced water in agriculture and other industries or dispose of it into waterways. There is serious concern about the safety of produced water and it being a widespread source of pollution. Current disposal and purification practices do not guarantee environmental pollutant’s removal from produced water. This research, “Optimization of thin film solid phase microextraction and data deconvolution methods for accurate characterization of organic compounds in produced water,” highlights the need for comprehensive chemical composition assessment of produced water, whether for reuse or disposal. Currently, EPA waives requirements that chemical companies (e.g., Syngenta in the case of atrazine) monitor for the presence of pesticides in waterways, endangering public health of the environment. Because produced water, whether treated or not, is typically not void of toxic […]

(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 “known or probable” 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: “This sweeping study exposes the terrible human cost of the EPA’s reckless decision to expand the use of dicamba. […]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 agency’s persistent practice of rubber-stamping dangerous pesticides.” Dicamba—a benzoic acid chemical that controls broadleaf weeds—is one of the most widely applied herbicides in corn production. As a result of weed resistant to […]

(Beyond Pesticides, March 27, 2020) Faced with the COVID-19 (coronavirus) threat, there is tremendous pressure to use toxic disinfectants, despite the availability of safer products. In fact, while the Centers for Disease Control and Prevention (CDC) is recommending 70% alcohol for surface disinfection, the U.S. Environmental Protection Agency’s (EPA) Office of Pesticide Programs is advising the use of unnecessarily toxic substances, and reducing standards that govern their allowance on the market. EPA’s pesticide program allowed 70 new disinfectants yesterday, at the same time that the agency overall announced that it is waiving enforcement of environmental standards during the coronavirus outbreak—a devastating blow to public health and environmental protection. Beyond Pesticides, in its factsheet, Protecting Yourself from COVID-19 (coronavirus) without Toxic Sanitizers and Disinfectants, says, “Fight the coronavirus with common sense prevention and safer disinfection products. Avoid products that increase vulnerability to respiratory problems.” (See the factsheet below.) To some extent, the expanded allowance of disinfection products on top of the 281 disinfectants previously permitted has been made possible by relaxing oversight on so-called “inert” or other ingredients that are not disclosed on product labels and often highly toxic. The agency says it is allowing the use of these “inerts” with “no […]

(Beyond Pesticides, February 6, 2020) Bill Bader, a Missouri peach farmer, is taking on agrichemical giants for damages to his crops, allegedly caused by the volatile herbicide dicamba drifting from neighboring properties. Mr. Bader says that not only did he lose over 30,000 trees, his remaining peaches are now smaller and his trees are less productive. According to Bader, the damage has cost him $20.9 million for which he seeks restitution. The case is claiming that Monsanto, now owned by Bayer, and German partner company BASF knew that the sale of their products would result in crop damage due to drift, but sold dicamba-resistant cotton and soybean seeds anyway. The companies deny the claims. Dicamba is a benzoic acid herbicide that exerts an auxin-like growth regulatory effect when absorbed by plant tissue, ultimately causing the plant to outgrow its nutrient supply and die. Originally developed in the 1950’s, dicamba has become more popular as crops become resistant to glyphosate. It is extremely volatile and prone to drift. Soybeans are particularly sensitive to dicamba, and drift damage can pit neighbor against neighbor in rural communities. Risk of crop damage alone can drive farmers to buy dicamba-resistant soybean seeds. In addition to […]

(Beyond Pesticides, January 27, 2020) United States military veterans suffering from bladder cancer, hypothyroidism, hypertension, and Parkinson’s-like symptoms after their exposure to Agent Orange will remain unprotected and uncompensated until at least late 2020, according to a letter sent by Veterans Affairs (VA) Secretary Robert Wilkie to U.S. Senator Jon Tester (D-MT). Send a letter to Veterans Affairs (VA) Secretary Robert Wilkie insisting that bladder cancer, hypothyroidism, hypertension, and Parkinson’s-like symptoms be added to the VA’s list of eligible conditions. Congress included a provision in the must-pass December federal spending bill requiring VA to provide legislators “a detailed explanation” for the now multi-year delay in determining whether to list the diseases. The provision is intended to cut through the ongoing delays, but there is no indication VA is going to meet the 30-day deadline. “The longer VA continues to drag its feet on expanding the list of conditions associated with Agent Orange, the longer our veterans continue to suffer—and die—as a result of their exposure,” Senator Tester said in a statement to the news site Connecting Vets. He continued, “It’s time for VA to stop ignoring the overwhelming evidence put forth by scientists, medical experts and veterans and do right by those who served. Any […]

(Beyond Pesticides, January 9, 2020) United States military veterans suffering from bladder cancer, hypothyroidism, hypertension and Parkinson’s-like symptoms after their exposure to Agent Orange will remain unprotected and uncompensated until at least late 2020, a letter sent by Veterans Affairs (VA) Secretary Robert Wilkie to U.S. Senator Jon Tester (D-MT) indicates. Congress included a provision in the must-pass December federal spending bill requiring VA to provide legislators “a detailed explanation” for the now multi-year delay in determining whether to list the diseases. This is seen by advocates for veterans as a serious lack of support and compensation just at a time when the current administration mobilizes the military. According to Military Times, 83,000 veterans suffer from bladder cancer, Parkinson’s-like symptoms or hypothyroidism, and an untold number have high blood pressure. The paper interviewed Army Sgt. Maj. John Mennitto, who explained, “Since we first spoke in 2016, I have been diagnosed with bladder cancer. . . I also have hypothyroidism. My greatest concern for me and my fellow veterans who have debilitating diseases caused by exposure to Agent Orange is that our family members will be left with nothing.” A robust 2014 review by the National Academy of Medicine recommended including […]

(Beyond Pesticides, October 15, 2019) EPA is requesting comment on its proposal to require data that will help it determine synergistic effects of some pesticides. EPA has received on a pressure on a number of fronts, including a report by the Center for Biological Diversity, a report by its own Inspector General, a letter from 35 Congressional Representatives, and research pointing to the unavoidability of synergistic effects—the chemical combinations that cause greater effects when mixed together than the sum of the individual chemical effects. Despite all of the evidence that synergism is the rule rather than the exception, EPA’s consideration focuses on a narrow range of cases in which pesticide product patents make claims of synergy. Tell EPA to always investigate synergy and to determine need for pesticides. One such product is Dow’s Enlist Duo, which combines glyphosate and 2,4-D in an attempt to overcome weed resistance. The focus on products and tank mixes where synergism is a selling point brings to light the fact that as a rule, EPA does not request efficacy data in registering pesticides not intended to protect public health. Thus, although required by law to weigh pesticide risks and benefits, EPA rarely has data to make […]

(Beyond Pesticides, October 11, 2019) The Office of Pesticide Programs (OPP) of the U.S. Environmental Protection Agency (EPA) is seeking public comment on a document that describes an “interim process” being used to assess potential synergistic effects of admixtures of pesticide active ingredients on non-target organisms. This interim risk assessment process was catalyzed in part by a 2015 lawsuit brought by a group of non-governmental organizations; that suit cited EPA’s failure to evaluate appropriately the impacts of a new herbicide, Enlist Duo, on non-target species, including some endangered species. EPA’s inattention to synergistic impacts on non-target species has long been a deficiency of EPA’s pesticide review and regulation and a focus for Beyond Pesticides’ work to factor in uncertainties, or unknowns, in registering pesticides under a precautionary approach. Although EPA recognizes that pesticide exposures occur in combinations, it evaluates a very limited number of such interactions. Manufactured by Dow AgroSciences, Enlist Duo combines glyphosate and 2,4-D. Increasingly, manufacturers create and market such “twofer” products as responses to the burgeoning issue of plant resistance to individual pesticides. As insects, fungi, weeds, or other “pests” inevitably develop resistance to pesticide, herbicide, fungicide, or insecticide compounds, the efficacy of the chemical treatment obviously plummets. […]

(Beyond Pesticides, August 8, 2019) The Food and Drug Association (FDA) recently approved the Impossible Burger, sparking a debate among environmentalists and lovers of plant-based meat products. The burger, manufactured by the Impossible Foods Group, is comprised of genetically engineered soy and heme (iron-containing molecule that is a component of hemoglobin and common to plants and animals). It contains over 11.3 times the amount of glyphosate residue as its counterpart, the non-GMO Beyond Burger. Spurring more controversy, the Impossible Foods Group recently attacked regenerative agricultural practices that advocates say are part of the solution to the current food system and climate crises. Impossible Foods Group uses genetically engineered soy that is resistant to herbicides such as glyphosate. Glyphosate, the active ingredient in Roundup, has recently taken the pesticide spotlight as over 18,000 plaintiffs are suing the agricultural giant Bayer over diagnoses of cancer and other diseases allegedly caused by use of their products. Ingestion or exposure to glyphosate can increase risk of cancer, disrupt estrogen, harm gut bacteria, and jeopardize overall health. Pesticide residues end up in food, and runoff or drift from agricultural fields contaminates soil, air, and water. The spraying of these chemicals can also endanger nearby operations […]

(Beyond Pesticides, July 18, 2019) Pesticide products containing the weed killer dicamba become more volatile and drift-prone in hot conditions and when tank-mixed with glyphosate, according to a recent study conducted by scientists at the University of Tennessee. The findings help explain rampant complaints from farmers in the South and Midwest experiencing crop loss and economic hardship as a result of drift from new dicamba products, which are formulated with glyphosate for use on genetically engineered (GE) cotton and soy. While states have taken the lead in regulating the use of GE dicamba products, top political officials within Administrator Andrew Wheeler’s EPA overruled the findings from agency scientists urging larger buffer zones to protect neighboring crops and farm fields. During a 60-hour window, scientists applied various GE dicamba products (Clarity and XtendiMax) over a range of temperatures and took air samples. As temperatures increased, so did the volatilization and drift of dicamba, even in formulations touted as “low volatility.” Adding glyphosate to the mixture produced stark results, increasing concentrations of dicamba in the air up to nine times compared to dicamba alone. Tom Mueller, PhD, a professor in the UT Department of Plant Sciences, stated in a press release that […]

(Beyond Pesticides, June 13, 2019) The U.S. allows the use of 85 pesticides that have been banned or are being phased out in the European Union, China or Brazil, according to a peer-reviewed study published last week by the academic journal Environmental Health. In 2016, the U.S. used 322 million pounds of pesticides that are banned in the E.U., accounting for more than one-quarter of all agricultural pesticide use in this country, according to the study. U.S. applicators also used 40 million pounds of pesticides that are banned or being phased out in China and 26 million pounds of pesticides that are banned or being phased out in Brazil. “It’s appalling the U.S. lags so far behind these major agricultural powers in banning harmful pesticides,” said Nathan Donley, PhD, a senior scientist with the Center for Biological Diversity and author of the study. “The fact that we’re still using hundreds of millions of pounds of poisons other nations have wisely rejected as too risky spotlights our dangerously lax approach to phasing out hazardous pesticides.” The study compared the approval status of more than 500 pesticides used in outdoor applications in the world’s four largest agricultural economies: the United States, European Union, China and Brazil. Report […]

(Beyond Pesticides, May, 7, 2019) Last week, the New York State legislature voted to phase out and eventually ban the use of the neurotoxic insecticide chlorpyrifos. The vote, 44-18 in the state Senate and 94-50 in the Assembly, is still awaiting the Governor’s signature, who is expected to sign the measure. As evidence of harm continues to accumulate, scientists have called for a ban, and a legal case works its way through the courts, pressure is mounting on the U.S. Environmental Protection Agency (EPA) to once and for all remove this harmful pesticide from use. New York’s legislation sets implementation dates that leapfrog a similar law banning chlorpyrifos that passed in Hawai’i last year. Although Hawai’i’s law takes effect beginning in July of this year, the state may provide temporary use permits for the chemical until December 2022. New York also phases in restrictions, first prohibiting aerial applications beginning January 2020, then prohibiting all use except on apple trees starting January 2021. The chemical will be completely banned for use in New York in December 2021. Chlorpyrifos is a highly toxic insecticide that has been linked to damaging and often irreversible health outcomes, particularly for pregnant mothers and their children, […]

(Beyond Pesticides, April 22, 2019) This Earth Day, please join us in celebrating, propagating, and educating about a misunderstood and beneficial plant: clover.  Clover: Provides your lawn with enough nitrogen to eliminate any need for ecologically hazardous synthetic fertilizers Acts as an important food source for declining pollinator populations Attracts earthworms and other beneficial soil microorganisms Remains green year-round Resists drought Helps your lawn resist disease A little history: “White clover used to be a standard ingredient in every grass seed mix; 75 years ago no one planted a lawn without mixing a little white clover in with the grass seed,” recounts Roger Swain, host of PBS’ The Victory Garden. After World War II, as the middle class grew and moved to suburban communities, chemicals developed during wartime found new uses on U.S. lawns. Chief among them was 2,4-D – an herbicide originally developed with the intent to wipe out potatoes in Germany and rice crops in Japan in a plan to starve the Axis powers into surrender. While 2,4-D was never used for that purpose, its ability to kill broadleaf plants while sparing grass species made it desirable on the farm for removing weeds around crops like wheat, corn, and […]
