(Beyond Pesticides, November 3, 2021) With a significant and increasing share of the U.S. population reporting sensitivities to certain chemicals, a team of researchers at University of California (Irvine), University of Texas (San Antonio), and the Massachusetts Institute of Technology is working to better understand how these symptoms develop. Although referred to by several names over the years, including Multiple Chemical Sensitivity (MCS) and Idiopathic Environmental Illness, medical professionals are now referring to the disease as Chemical Intolerance, or Toxicant Induced Loss of Tolerance (TILT), to better represent the disease process and range of nervous system symptoms that individuals develop to low level chemical exposures. “We established evidence of this previously understudied disease process,” said Shahir Masri, Sc.D, at University of California, Irvine. “Our insights will help public health scientists, physicians and policymakers better understand how to minimize harmful exposures and prevent future disease.” TILT is characterized by a two-step process. First, there is an “initiation exposure event,” whereby an individual is either repeatedly exposed to low levels of certain chemicals, or experiences a major exposure incident. In the second stage, affected individuals are “triggered” even by minute exposures, not only to the chemical that affected them in the first […]

(Beyond Pesticides, November 2, 2021) Cover crops create habitat that draw in pest predators and help mitigate crop injury, finds research published in the journals Agroecosystems and Biological Control from scientists at the University of Georgia. Expanded predator diversity can reduce pest pressure that drives conventional chemical farmers to apply toxic pesticides, and the authors of the study find the practice to be economically viable within these cropping systems. “There’s a motion of change going on where growers are thinking more about using natural systems instead of just using pesticides,” said co-author Jason Schmidt, PhD in a news release. “Producers must use all tools available to make a profit, so if they can promote beneficial insects in the system to aid in pest control,  fewer inputs are needed and that should lead to reduced costs of production. ” To determine how beneficial cover crops were to cotton production, researchers began with experimental crops established over two years in 2016 and 2017 in Georgia. Twelve cover crops plots were established with crimson clover and rye, while a plot not planted with cover crops was used as a control. Researchers planted the cover crop in early November after the previous cotton crop […]

(Beyond Pesticides, October 28, 2021) A study published in Frontiers in Environmental Science finds the popular herbicide glyphosate negatively affects microbial communities, indirectly influencing plant, animal, and human health. Exposure to sublethal concentrations of glyphosate shifts microbial community composition, destroying beneficial microorganisms while preserving pathogenic organisms. Glyphosate is the most commonly used active ingredient worldwide, appearing in many herbicide formulas, including Bayer’s (formerly Monsanto) Roundup®. The use of this chemical has been increasing since the inception of crops genetically modified to tolerate glyphosate over two decades ago. The toxic herbicide readily contaminates the ecosystem with residues pervasive in both food and water commodities. In addition to this study, the scientific literature commonly associates glyphosate with human, biotic, and ecosystem harm, as a doubling of toxic effects on invertebrates, like pollinators, has been recorded since 2004. The authors caution, “[O]utbreaks of several animal and plant diseases have been related to glyphosate accumulation in the environment. Long-term glyphosate effects have been underreported, and new standards will be needed for residues in plant and animal products and the environment.” With an increasing number of reports on the relationship between glyphosate and human health, including potential effects on the human gut microbiome, advocates are calling on global leaders to eliminate chemical […]

(Beyond Pesticides, October 27, 2021) Declines in pollinator populations throughout the world may result in the loss of tens of thousands of wild flowering plants that rely on their services, according to research published this month in the journal Science Advances. “Our paper provides the first global estimate of how many plant species mostly or completely rely on animal pollinators to make seeds and thus to reproduce,” wrote author James Rodger, PhD, in an article in The Conversation. “We found that it’s about 175,000 plant species – half of all flowering plants. This means declines in pollinators could cause major disruptions in natural ecosystems, including loss of biodiversity.” Pollinators are being threatened with multiple interacting stressors, from climate change, to pesticide use, disease, habitat destruction, and other factors. In the US, an increasing number of pollinators, including iconic species like the American bumblebee and monarch butterfly, are being added or in consideration for listing under the Endangered Species Act. Systemic neonicotinoid insecticides implicated for their earth-spanning hazards to pollinator populations themselves put 89% or more of U.S. endangered species at risk. Many are aware of the fact that pollinators help make available one in three bites of food. Research studies […]

(Beyond Pesticides, October 25, 2021) The Environmental Protection Agency (EPA) is requesting public comments on its draft Biological Evaluations (BEs) for neonicotinoid insecticides imidacloprid, clothianidin, and thiamethoxam by 11:59 pm (EDT) on Monday, October 25, 2021. The BEs will factor into EPA’s registration review decisions on the three bee-toxic insecticides. Written comments must be submitted through Regulations.gov. Please feel free to cut and paste parts of  Beyond Pesticides’ comments (linked here) or cut and paste into Regulations.gov the suggested comment language at the very bottom of this alert.  Tell EPA to protect endangered species from pesticides. EPA’s Biological Evaluations for these highly toxic chemicals make no agency conclusion or recommendation that would trigger a request to initiate formal Endangered Species Act (ESA) §7(a)(2) consultations with the U.S. Fish and Wildlife Service (USFWS) to determine a possible jeopardy finding for the listed species and requisite mandatory use restrictions of the relevant pesticide. This, despite the fact that for imidacloprid the agency’s draft Biological Evaluation made a May Affect determination for 89% of the 1821 species considered and 90% of the 791 critical habitats considered. Strikingly, a May Affect determination was made for 100% of amphibian and avian listed species and their […]

(Beyond Pesticides, October 21, 2021) A study published in Environment International finds higher rates of various cancers among agricultural workers, with multiple myeloma (blood cancer) and melanoma (skin cancer) disproportionately impacting female farmers. Although research studies link cancer risk to genetic and external factors (e.g., cigarette smoke), there are increasing reports and scientific studies that pesticide exposure augments the risk of developing common cancers like melanoma and less common cancers like multiple myeloma. This study highlights the importance of understanding how pesticide use can increase the risk of latent diseases, which do not immediately develop upon initial exposure. The researchers note, “Given the large size of the agricultural population worldwide and the presence of various potential hazards in its working environment, such epidemiological data are important in improving occupational health measures and ensuring better workers’ health.” To investigate the cancer incidence patterns, researchers evaluated data from the AGRICOH database involving various international studies. The studies assessed pesticide exposure scenarios, which researchers use to determine the etiological (causal) agent of cancer incidences among farmers relative to the general population. Researchers analyzed data from eight different AGRICOH groups in various countries: France (AGRICAN), the U.S. (AHS, MESA), Norway (CNAP), Republic of Korea (KMCC), Denmark […]

(Beyond Pesticides, October 19, 2021) Exposure to the insecticide malathion increases risk of developing chronic kidney disease (CKD), according to a study recently published in the International Journal of Environmental Research and Public Health. According to study co-author Nicholas Osborne, PhD, CKD is on the rise in developing countries in Southeast Asia and Central America, and, “[n]early one in 10 people in high income countries show signs of CKD, which is permanent kidney damage and loss of renal function.” Although CKD risk increases with age, and is associated with other health factors like smoking, heart disease, and diabetes, cases without clear cause are increasingly common, indicating the that environmental factors are likely playing a role. Researchers began with data drawn from the United States’ National Health and Nutrition Examination Survey (NHANES), an ongoing study that assesses Americans’ health and nutritional status through interviews, physicals, and other health tests. Urine samples taken from individuals enrolled in NHANES 2001-2004 and 2007-2010 (tests within years between these dates did not analyze specific pesticides) were reviewed for the presence of pesticides, and compared against data collected on kidney function. In addition to malathion, 2,4-D, chlorpyrifos, and 3-PBA, the major metabolite for most synthetic pyrethroid insecticides, […]

(Beyond Pesticides, October 18, 2021) The most recent science on pesticides raises serious health and environmental effects associated with pesticide use for lawn and landscape management. While the data is often not assembled in one place, updated factsheets bring together the science on the 40 commonly used pesticides used for conventional landscape management. Governors have the authority to stop the use of these hazardous materials that are used on parks and playgrounds, either by executive order or through their work with their state legislature, and transition land management to organic practices. Tell your governor to stop hazardous pesticide use on state lands and transition to organic land management. The new factsheets document with scientific citations a wide range of diseases and ecological effects linked to pesticides. The underlying analysis supporting the adverse health and environmental effects identified in the factsheets are based on toxicity determinations in government reviews and university studies and databases. What do the factsheets disclose? Of the 40 most commonly used lawn and landscape pesticides, in reference to adverse health effects… 26 are possible and/or known carcinogens 24 have the potential to disrupt the endocrine (hormonal) system 29 are linked to reproductive effects and sexual dysfunction 21 […]

Health and environmental effects disclosed on factsheets to guide community decisions on lawn and landscape management that do not poison people and contaminate the environment. WASHINGTON, D.C. (October 14, 2021) — Today, the national environmental and public health group Beyond Pesticides is releasing its health and environmental effects factsheets for “40 Commonly Used Lawn Pesticides,” updating and expanding on previous factsheets on 30 pesticides. These comprehensive factsheets documents with scientific citations a wide range of diseases and ecological effects linked to pesticides. The underlying analysis supporting the adverse health and environmental effects identified in the factsheets are based on toxicity determinations in government reviews and university studies and databases. What do the factsheets disclose? Of the 40 most commonly used lawn and landscape pesticides, in reference to adverse health effects, 26 are possible and/or known carcinogens, 24 have the potential to disrupt the endocrine (hormonal) system, 29 are linked to reproductive effects and sexual dysfunction, 21 have been linked to birth defects, 24 are neurotoxic, 32 can cause kidney or liver damage, and 33 are sensitizers and/or irritants. Regarding adverse environmental effects, 21 are detected in groundwater, 24 have the ability to leach into drinking water sources, 39 are toxic to […]

(Beyond Pesticides, October 12, 2021) Tell President Biden and Congress that there is no room for agriculture policies that are not in line with the Executive Memorandum and directive Modernizing Regulatory Review. USDA must remove all barriers to a national transition to organic agriculture. One of President Biden’s first actions, on the day of his inauguration, was the Executive Memorandum and directive Modernizing Regulatory Review, requiring the heads of all executive departments and agencies to produce recommendations for improving and modernizing regulatory review, with a goal of promoting public health and safety, economic growth, social welfare, racial justice, environmental stewardship, human dignity, equity, and the interests of future generations. This mandate should reverse the trend of regulatory review, which has so far protected the status quo, rather than advancing urgently needed change. Why, then, do we see Secretary of the U.S. Department of Agriculture Tom Vilsack opposing moves in the direction laid out by the Presidential directive? A recent Mother Jones article by Tom Philpott focuses on Mr. Vilsack’s opposition to the “Farm to Fork” initiative in the European Union, which aims to “push the continent’s agriculture in a healthier, more resilient direction, to reduce the use of toxic chemicals […]

(Beyond Pesticides, October 8, 2021) Taking a page from the playbook of Trump Administration Secretary of Agriculture Sonny Perdue, the current secretary, Tom Vilsack, used a September G20 summit in Italy to target the European Union’s “Farm to Fork” (F2F) strategy, a part of its European Green Deal. Mr. Perdue had said that F2F is “more . . . ‘political science’ than demonstrated agricultural science”; Secretary Vilsack called it “a path very different from the one the U.S. is pursuing.” The F2F initiative aims to transition the EU to a sustainable food system such that it also achieves significant mitigation of climate change. But Mr. Vilsack chose to counter the F2F efforts by promoting an “alternative strategy” — under the moniker “Coalition for Productivity Growth” — through which “other nations pledge not to follow the European path on farm policy.” He has described this alternative, U.S.-led strategy as “a market-oriented, incentive-based, voluntary system [that] is effective” at slashing agricultural carbon emissions. Climate, pesticide, organics, and other environmental and health advocates, including Beyond Pesticides, are troubled by these actions. Mother Jones poses the central question in the headline of its September 30 article: Why is Secretary Vilsack So Afraid of a Plan to Cut […]

(Beyond Pesticides, October 7, 2021) The Arizona State Auditor General reports a lack of groundwater monitoring for pesticides and other contaminants by the Arizona Department of Environmental Quality (ADEQ). For over six years, the agency failed to monitor groundwater and soil for agricultural pesticide contamination. Furthermore, the agency did not implement key groundwater monitoring processes over four years, despite law requirements. This lack of waterway monitoring resulted in an increased number of impaired surface waters across the state.   Pesticide contamination in waterways is historically commonplace and widespread throughout U.S. rivers and streams, with at least five or more different pesticides present in 90 percent of water samples. Thousands of tons of pesticides enter waterways (e.g., rivers, streams, lakes, oceans) around the U.S. from agricultural and nonagricultural sources, contaminating essential drinking water sources, such as surface water and groundwater. Reports like these are essential in determining appropriate regulatory action to protect human, animal, and environmental health from chemical toxicant contamination. The report states, “[The] Department has not developed all required aquifer water quality standards, conducted key ongoing groundwater monitoring of the State’s aquifers, monitored for agricultural pesticides in groundwater and surrounding soil, or reduced the number of impaired surface waters in the State, limiting its […]

(Beyond Pesticides, October 6, 2021) Agricultural soils under monoculture cropping systems are not as healthy as soils with diverse plantings, finds research recently published in the journal Agrosystems, Geosciences and Environment. Soil and soil quality are declining rapidly in the United States and around the world, with recent data indicating that the U.S. Corn Belt has lost 35% of its topsoil. Advocates say it is critical that the response to this problem focus on practices that conserve and improve the soil health by building organic matter and healthy microbial populations. “Understanding the management practices that lead to healthier soils will allow farmers to grow the same crops while reducing costly chemical inputs (fertilizers, pesticides, herbicides) and protecting the environment,” said study coauthor Lori Phillips, PhD. To investigate disparities in soil health between cropping systems, researchers analyzed a long-term cropping system that includes 18 years of continuously grown soy, corn, and perennial grasses. Each cropping system was evaluated for its bacterial and fungal population, as well as a test called CNPS, which measures the enzymes produced by microbes specifically related to the soil’s carbon, nitrogen, phosphorous, and sulfur cycles. Researchers indicate that these measurements create “a holistic measure of biological activity,” […]

(Beyond Pesticides, October 4, 2021) Recent findings of high levels of toxic pesticides in products permitted to be used as “minimum risk pesticides” (terminology used for essentially nontoxic) point to the need for greater oversight of these products and more severe penalties for violations. Pesticides classified as minimum risk are allowed under Section 25(b) of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) [40 CFR 152.25(f)] to be used without going through EPA’s pesticide registration process. These products are limited to a specific list of ingredients, and all ingredients, including “inert” ingredients, are required to be listed on the label.  Minimum risk pesticides are used by organic growers, municipalities, and others who are not permitted to use, or choose to avoid, toxic chemicals.  Tell EPA and Congress to protect the integrity of minimum risk pesticides. Organic growers can lose their organic certification if they apply materials that are prohibited, which include the toxic ingredients glyphosate, bifenthrin, permethrin, cypermethrin, and carbaryl, found by the state of California in dangerous and misbranded Eco-MIGHT and W.O.W. (Whack Out Weeds!) products, falsely labeled as 25(b) minimum risk. Contamination of these products came to light in late July, when the California Department of Food and […]

(Beyond Pesticides, September 30, 2021) Individuals working or living in areas with frequent neurotoxic pesticide use experience more amyotrophic lateral sclerosis (ALS) incidences than the general population. The study, published in NeuroToxicology, finds a positive association between sporadic (non-genetic, spontaneous) ALS incidences among individuals exposed to neurotoxic pesticides.  Amyotrophic lateral sclerosis (or Lou Gehrig’s disease) is a neurodegenerative disease that affects the nerves in the brain and spinal cord. As many as 16,000 – 20,000 Americans live with this condition, which weakens muscle/motor function leading to loss of muscle control for walking, talking, eating/swallowing, and breathing. Severe ALS progression is fatal and has no current cure. Although research supports genetic factors play a role in disease etiology (cause), most ALS cases do not result from genetic inheritance. Several research studies demonstrate exposure to environmental or work-related toxicants (i.e., pesticides) predispose humans to the disease. With researchers predicting a global ALS incidence increase of 69% by 2040, identifying ALS’s causal factors are important to future research. Therefore, research like this showcases the importance of assessing aggregate health risks associated with toxic chemical exposure, especially for illnesses, which are not curable. In this study, the researchers note, “[W]e identified pesticides applied to crops in the area of […]

(Beyond Pesticides, September 29, 2021) Bats foraging in chemical-intensive banana plantations have much less gut diversity than bats foraging in organic banana fields and natural forestland, finds research published this month in the journal Frontiers in Ecology and Evolution. Although there is increasing recognition that a diet of conventional, chemically grown food leads to adverse disruptions of the gut microbiome (also known as dysbiosis), little research has been conducted on the effect of production practices on the gut of wild foraging species. According to the present study there are significant differences that regulators must begin to account for in pesticide risk assessments, and consumers should consider when making choices at the supermarket. Researchers focused their investigation on Pallas’s long-tongued bat (Glossophaga soricina), a nectar feeding bat native to Central and South America. The bat is highly adapted to human environments, sustaining populations in both conventional and organic banana plantations, as well as surrounding forest land. For the study, researchers trapped nearly 200 bats across the country of Costa Rica over a 22-month time span. After trapping, physiological characteristics, like size and body weight, were measured, and bat guano was analyzed for its microbial population. All sampled bats were released back […]

(Beyond Pesticides, September 28, 2021) A widely used mosquito pesticide may exacerbate the effect of the Zika virus on fetal brain development, according to research published by an international team of scientists in the journal Environmental Pollution. Pyriproxyfen, an insect growth regulator often used as a mosquito larvicide, is registered for use in hundreds of commonly used pesticide products. But scientists have discovered that the pesticide’s mode of action has the potential to worsen the public health mosquito diseases the chemical aims to control. The research reinforces the extent of unknowns associated with synthetic pesticide exposure, underlining the need for a focus on nontoxic and ecological mosquito management. Scientists base their research on reports that in Brazil, during the 2015 Zika epidemic, certain areas of the country experienced higher rates of microcephaly. Microcephaly is a rare condition that causes pregnant women’s fetus to develop severe cranial deformities, alongside a range of other symptoms that include vision problems, hearing loss, feeding issues, developmental delays and seizures. The present study aimed to see how pyriproxyfen, used at higher rates in areas where microcephaly Zika cases were recorded, may interact with the virus. In an article published in The Conversation, researchers note that […]

(Beyond Pesticides, September 23, 2021) A study by Claremont Graduate University finds exposure to agricultural pesticides increases brain cancer risk up to 20 percent. This study expands on a 1998 study evaluating brain cancer risk among the farm population using epidemiologic studies. The etiology (cause) of brain cancer is inconclusive for many forms, including glioma and meningioma. Brain cancer risk factors include family history and exposure to radiation. However, geographical variance in brain cancer incidents suggests environmental pollutants like pesticides contribute to risk. Various research studies already note the adverse effects pesticide exposure has on the brain. These effects range from headaches and tumors to learning and developmental disabilities among children and adults. Although general cancer incidents are decreasing, brain and nervous system cancers are rising. Therefore, studies like this highlight the need to reevaluate pesticide exposure limits for those working with or around agricultural chemicals to prevent chronic, deadly diseases. The study researchers note, “This comprehensive review and meta-analysis encompassing 42 years of the epidemiologic literature and updating two previous meta-analyses by 20 years supports an association between farming and brain cancer incidence and mortality.[…]Our analyses suggest that the elevated risk has been consistent over time, and the addition of newer studies […]

(Beyond Pesticides, September 22, 2021) Health and environmental organizations are urging the U.S. Environmental Protection Agency (EPA) and state pesticide regulators to immediately stop the use and sale of dangerous and misbranded Eco-MIGHT and W.O.W. (Whack Out Weeds!) products, falsely labeled as 25(b) minimum risk. Recent laboratory testing by the state of California found the presence of hazardous pesticides, including glyphosate, bifenthrin, permethrin, cypermethrin, and carbaryl in these products. “From organic farmers to municipal landscapers and home gardeners, consumers employing minimum risk products are working intentionally to avoid the dangers associated with toxic pesticide exposure,” said Jay Feldman, executive director of Beyond Pesticides. “It is critical that EPA and state regulators coordinate to ensure the integrity of the minimum risk program.” Coordination is critical yet reports indicate that EPA is falling down on the job. The issue first came to light in late July, when the California Department of Food and Agriculture’s (CDFA) State Organic Program issued a Stop Use Notice to farmers alerting them to adultered Eco-MIGHT and W.O.W products. The products make a range of claims, marketed as “organic,” “natural,” “glyphosate-free,” and “non-toxic and safe.” As CDFA Secretary Karen Ross noted, “It is imperative that we alert California […]

(Beyond Pesticides, September 17, 2021) Against the backdrop of what The New York Times in 2018 called the “insect apocalypse,” and the dire plight of pollinators in particular, Friends of the Earth (FOE) recently issued its retailer scorecard, which benchmarks “25 of the largest U.S. grocery stores on pesticides, organic offerings and pollinator health”— with the vast majority of retailers failing to protect pollinators. FOE reporting shows some, but far too slow and anemic, progress by corporate actors in enacting pollinator- and bee-friendly policies across both retail sites and supply chains. Such policies, to be genuinely effective and protective of pollinators (and human health), would eliminate or at least dramatically reduce the presence of pesticides in the food supply. The path out of the chemical pesticide quagmire is organic: companies must do more to move suppliers to organic, regenerative production practices, and EPA should be pulling these toxic compounds from the market. Tracking the pollinator policies and enforcement activities of various huge companies yields a useful barometer in monitoring the travel of pesticides to the consumer. Yet the results in the FOE scorecard — e.g., only two of those 25 retailers scored even in the “B” range, and 21 scored […]

(Beyond Pesticides, September 16, 2021) A study published in Chemosphere finds persistent organic pollutants (POPs), including organochlorine pesticides (OCPs), polychlorinated biphenyls (PCBs), and polybrominated diphenyl ethers (PBDEs), are present in the serum and placenta of pregnant mothers, as well as multiple fetal organs. Many studies indicate prenatal and early-life exposure to environmental toxicants increases susceptibility to diseases, from learning and developmental disabilities to cancer. However, this study is one of the first to demonstrate the presence of chemical toxicants in fetal tissue that are not present in maternal serum or placental samples. Prenatal development is one of the most vulnerable periods of exposure when the fetus is most susceptible to the harmful effects of chemical contaminants. Therefore, studies like these help government and health officials better identify fetal exposure contaminants and subsequent health concerns otherwise missed by current chemical monitoring methods. The researchers note, “These findings call for further evaluation of the current matrices used to estimate fetal exposure and establish a possible correction factor for a more accurate assessment of exposure in utero. We disclose the full data set on individual exposure concentrations to assist in building in silico models for prediction of human fetal exposure to chemicals.” Several studies associate early-life exposure to toxic chemicals […]

(Beyond Pesticides, September 15, 2021) Toxic pesticide use, and glyphosate in particular, degrades the health of freshwater ecosystems by harming species that form the basis of aquatic food chains, according to research published by scientists at McGill University. In a series of studies, scientists investigated how freshwater bacteria and zooplankton were affected by varying levels the weed killer glyphosate, the neonicotinoid insecticide imidacloprid, and nutrient levels. “Because plankton form the foundation of the food chain in freshwater ecosystems, it is very important to understand how plankton communities respond to widely used pesticides,” said Jesse Shapiro, PhD, an Associate Professor in McGill’s Department of Microbiology and Immunology. “Our research shows that the structure of these communities can be impaired under currently acceptable North American water quality guidelines.” Two separate experiments were conducted under similar conditions in order to properly investigate the effects of pesticide exposure on either zooplankton or freshwater bacteria. For both studies, target species were exposed to varying rates of glyphosate, imidacloprid, or both chemicals at either high or low water nutrient levels. Researchers conducted this study by establishing a series of outdoor experimental ponds, intended to mimic freshwater ecosystems by using Lake water and evenly distributing organisms throughout […]

(Beyond Pesticides, September 13, 2021) The National Organic Standards Board (NOSB) is receiving written comments from the public through September 30. This precedes the upcoming public comment webinar on October 13-14 and online meeting October 19-21—in which the NOSB deliberates on issues concerning how organic food is produced. Written comments must be submitted through Regulations.gov. As always, there are many important issues on the NOSB agenda this Fall. For a complete discussion, see Keeping Organic Strong (KOS) and the Fall 2021 issues page. In the spirit of “continuous improvement,” we urge you to submit comments (please feel free to use our comments on the KOS page) that contribute to an increasingly improved organic production system. The Organic Foods Production Act (OFPA) requires that all synthetic materials used in organic production be approved by the NOSB, included on the National List, and reassessed every five years. Among those up for sunset review this Fall are some controversial materials—copper sulfate, carrageenan, and list 3 “inerts.” In addition, the NOSB is once more considering a petition to allow the antibiotic kasugamycin in fruit production. Copper sulfate is used in organic rice production to control algae and an invertebrate known as tadpole shrimp. It […]
