(Beyond Pesticides, November 21, 2012) The National Organic Coalition (NOC) yesterday sharply condemned recommendations contained in the final report of the Advisory Committee on Biotechnology and 21st Century Agriculture (AC21), a group appointed by the U.S. Department of Agriculture (USDA) to address transgenic contamination of organic and non-genetically engineered (GE) crops. Of particular concern in the report is the recommendation that organic and non-GE conventional farmers pay for crop insurance or self-insure themselves against unwanted GE contamination. NOC strongly asserts that this proposal allows USDA and the agricultural biotechnology industry to abdicate responsibility for preventing GE contamination, while making the victim of GE pollution pay for damages resulting from transgenic contamination. “The AC21 report takes responsibility for GE contamination prevention out of the hands of USDA and the biotech industry where it belongs and puts it squarely on the backs of organic and non-GE farmers,” said Andrew Kimbrell, executive director at Center for Food Safety and a NOC member. “This ill-conceived solution of penalizing the victim is fundamentally unjust and fails to address the root cause of the problem – transgenic contamination.” In August 2011, USDA convened AC21 and charged it with identifying compensation mechanisms to address GE contamination. The […]

(Beyond Pesticides, November 20, 2012) Thanksgiving offers an opportunity for family and friends to eat, drink and be thankful for the bounty of the organic harvest. Unfortunately, there are a host of pesticides, genetically engineered materials, and others in conventional Thanksgiving foods that not only impact human health, but threaten the environment. Read below for some easy tips and suggestions for a healthful Thanksgiving day feast. Organic, free-range, and local turkeys The turkey is the symbol of a traditional Thanksgiving meal. However, turkeys are often fed grains treated with pesticides, medicated with antibiotics, and engorged with steroids and hormones. Additionally, turkeys are often fed an inorganic arsenic, a known carcinogen, which is used to promote growth and for pigmentation. In order to avoid all these, your best bet is to invest in an organic free-range turkey (pictured right), which is free of hormones, steroids or antibiotics. Want to forgo the turkey altogether? Be sure to choose an organic meatless option. Avoid Genetically Engineered Food: Go Organic There are additionally, a number of Thanksgiving products that probably contain genetically-engineered (GE) ingredients (although the formulations are often considered proprietary trade secrets). According to GMO Inside, some common GE foods used during Thanksgiving […]

(Beyond Pesticides, November 9, 2012) Proposition 37, the statewide proposition California voted on to label foods produced with genetically engineered (GE) ingredients, was narrowly defeated at the polls on Wednesday night by a margin of 6.2 percentage points, however uncounted votes may shift the results. Had it been approved, Californians would have required labels for raw or processed food with GE ingredients and it would have prohibited the labeling and advertising of foods using the misleading term “natural.” Though campaign organizers and most news outlets are announcing defeat, the fight is not over yet. Organizers of the “Yes on 37” campaign have begun to regroup, focusing on 4.2 million Californians that voted yes and building a grassroots movement with 10,000 volunteers. Their campaign’s optimism is highlighted by their campaign statement that was released yesterday online: Yesterday, we showed that there is a food movement in the United States, and it is strong, vibrant and too powerful to stop. We always knew we were the underdogs, and the underdogs nearly took the day. Dirty money and dirty tactics may have won this skirmish, but they will not win the war. If Prop 37 passed, California would have been the first state […]

(Beyond Pesticides, November 8, 2012) In response to an emergency exemption granted by the U.S. Environmental Protection Agency (EPA) to allow the unregistered use of the herbicide fluridone on cotton in order to control glyphosate-resistant weeds, the agency announced in the Federal Register Monday that it is establishing time-limited tolerances for residues of the chemical on food. Because resistance to herbicides in genetically engineered crops is predictable and expected, Beyond Pesticides has challenged EPA’s use of the emergency exemption provision of the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA), Section 18, in this and other similar cases. According to EPA, of the glyphosate-resistant weeds, Palmer amaranth has become the most severe weed problem in Arkansas cotton production. It can reduce yields of cotton by more than 50 percent if there is a density of at least 10 of these weeds per row. Over 95% of Arkansas cotton and 80% of soybeans is genetically engineered (GE) to be glyphosate tolerant. Because glyphosate is the base herbicide used for weed control in this region, economic loss is expected on nearly 25% of acres grown. Over-reliance on herbicide-tolerant GE crops have caused the spread of resistant weeds that force farmers on the pesticide […]

(Beyond Pesticides, November 7, 2012) Pregnant beluga whales pass to their fetus a portion of the persistent organic pollutants, PCBs and flame retardants, they carry in their bodies, report researchers who measured the chemicals in the animals’ blubber. The study is one of the first to show whales, like people, can transfer and expose their developing offspring to persistent contaminants, whose long-term health effects continue to remain unclear. A study of Arctic beluga whales (Delphinapterus leucas) confirms that mothers can pass more than a tenth of their chemical burden of PBDE flame retardants and PCBs to their unborn calves. This study found that the mother whales transferred, on average, 11.4% (7.5”‰mg) and 11.1% (0.1”‰mg) of their polychlorinated biphenyl (PCB) and polybrominated diphenyl ether (PBDE) blubber burden to their near-term fetuses. Mammals transfer contaminants, usually persistent organic pollutants (POPs), during pregnancy to the developing fetus and during lactation when the baby is nursing. Lactation transfer has been well studied in marine mammals, but very little is known about the transfer of pollutants during pregnancy. POPs are resistant to environmental degradation through chemical, biological, and photolytic processes. Because of this, they have been observed to persist in the environment, to be capable […]

(Beyond Pesticides, November 6, 2012) In efforts to stamp out the deadly disease Dengue fever, officials in Brazil are in the process of releasing millions of genetically engineered (GE) mosquitoes into the environment. However, some in the environmental community are concerned about the possible non-target effects of this experiment, and urge additional research in the lab before releasing the insects into the natural world. According to the Los Angeles Times, the experiment is taking place in the small town of Itaberaba, in Brazil’s Bahia state. The company overseeing the release, London-based Oxitec, also developed the GE insects. GE mosquitoes are raised in the laboratory, where the eggs of female mosquitoes are injected with a gene that produces sterile male mosquitoes. The modified male mosquitoes are then released into the environment en masse where they crowd out native males and mate with available females. The offspring from these mosquitoes are supposed to die before they hatch. In the town of Itaberaba, 84% of mosquito larvae now carry the modified gene, and the state government has approved an expansion of the program into five additional neighborhoods. GE mosquitoes have previously been released into uninhabited areas of India and Malaysia, and future plans […]

(Beyond Pesticides, November 2, 2012) Despite the onslaught of advertisements saying otherwise, on November 6th California voters will be asked a simple yes or no question: Do you have a right to know if the food you purchase contains genetically engineered (GE) ingredients? Industrial chemical corporations and conventional food manufacturers think your answer to this simple question could dent their profits, possibly damage their image. So they’re attempting to make it as confusing as possible for citizens to understand the issue. The “No on 37” campaign has flooded California’s airwaves with dubious statements and misrepresentations in attempts to scare consumers away from voting in their best interests. And they’ve made a difference. Back in March, a survey revealed that 91% of consumers nationwide favor the labeling of GE foods, a remarkable consensus that cut across party lines. Up until the past few weeks, before the “No on 37” ads started appearing, there was a 2:1 margin in favor or labeling GE foods. However, recent polls show Prop 37 in a dead heat. What happened? In early August, Beyond Pesticides reported on how pesticide manufacturers are “pushing hard” to block the passage of this proposition. At the time, the “No” campaign […]

(Beyond Pesticides, October 31, 2012) On Halloween, scarier things then spooky ghouls and goblins may be lurking in places that you don’t expect; places like your child’s candy bag. Over 80% of processed food in the U.S. contains genetically engineered (GE) ingredients, and most major candy products are no exception. As responsible parents and adults, none of us willingly intend to pass out candy that contains GE ingredients to our children, but as it currently stands we don’t have the right to know whether we are or not. However, nobody wants to be “those neighbors” who give out pennies or pamphlets instead. Luckily, alternatives like candy with all organic ingredients can keep trick-or-treaters happy and give you piece of mind. Halloween candies can contain a wide variety of GE ingredients. According to Green Halloween the top GE ingredients in candy are sugar (GE sugar beets), high fructose corn syrup (GE corn), corn starch (GE corn), soy lecithin (GE soy), soybean oil (GE soy), modified food starch (GE corn), fructose, dextrose, glucose (GE corn, cottonseed oil (GE cotton), and canola oil (GE canola). GE crops have become ubiquitous in U.S. agriculture with 93% of soy, 93% of cotton, and 86% of […]

(Beyond Pesticides, October 25, 2012) In stark contrast with last week’s decision in the midwest, a federal court ruled in favor of halting cultivation of genetically engineered (GE) crops in all national wildlife refuges in the Southeastern U.S. on Tuesday. The suit, filed by Public Employees for Environmental Responsibility (PEER), Center for Food Safety (CFS), and Beyond Pesticides, is a part of a series of legal actions taken against the U.S. Fish & Wildlife Services (FWS) for entering into cooperative farming agreements for GE crops on wildlife refuge sites without the environmental review required by the National Environmental Policy Act (NEPA) and refuge management laws. This latest ruling bars FWS from entering into cooperative farming agreements for GE crops on the 128 refuges across eight states, including the 25 refuges currently growing GE crops. The requirement of environmental reviews will likely prevent the planting of crops in 2013 and 2014, and may result in a permanent end to the practice, as native successional grasses reclaim fallow refuge tracts. This ruling is the third in a series of victories against FWS. In March 2009, the same groups won a similar lawsuit against GE plantings on Prime Hook National Wildlife Refuge. In […]

(Beyond Pesticides, October 23, 2012) It’s a story we’ve heard for far too long. Research published yesterday in the journal Nature concludes that when bees are exposed to pesticides their colonies have a greater propensity to fail, again raising the urgent need for regulatory action to protect pollinators. This study adds to the body of science that shows toxic pesticide dependency in agriculture is undermining our food supply. Concerned citizens Take Action! Join us this Thursday, October 25th at Noon outside EPA Headquarters (340 12th St NW (12th and Pennsylvania Ave)) for a rally to tell EPA that it must act to protect pollinators now. The rally will feature speakers from various nonprofit and environmental organizations, commercial and urban beekeepers, film documentarians and more, including: ”¢ David Hackenberg, Commercial Beekeeper, PA ”¢ Jay Feldman, Executive Director, Beyond Pesticides ”¢ Peter T. Jenkins, Attorney/Consultant, Center for Food Safety ”¢ Jim Doan, Commercial Beekeeper, NY ”¢ Maryam Henein, Director “Vanishing of the Bees” ”¢ Meme Thomas, Baltimore City Beekeeper ”¢ Kevin Hansen, Director of “Nicotine Bees” and Sierra Club Representative The Nature study, “Combined pesticide exposure severely affects individual- and colony-level traits in bees,” followed 40 bumblebee colonies for four weeks. While […]

(Beyond Pesticides, October 22, 2012) A lawsuit challenging the U.S. Fish and Wildlife Service’s (FWS) practice of permitting genetically engineered (GE) crops on wildlife refuges was dismissed by a U.S. District Court for the District of Columbia. The suit filed by Public Employees for Environmental Responsibility (PEER), the Center for Food Safety (CFS), and Beyond Pesticides, charged that FWS unlawfully entered into cooperative farming agreements and approved planting of GE crops in 54 national wildlife refuges in various states without the environmental review required by the National Environmental Policy Act (NEPA) and in violation of FWS policy. U.S. District Judge James Boasberg in Washington, D.C. rejected the plaintiff’s arguments, ruling that the “agency’s actions were not arbitrary, capricious, an abuse of discretion or otherwise not in accordance with law.” The U.S. Fish and Wildlife Service (FWS), which oversees 150 million acres of refuges, allowed farmers to plant GE corn and soybeans on a limited basis in eight Midwestern states. The plaintiffs — Center for Food Safety, Beyond Pesticides, Public Employees for Environmental Responsibility and the Cornucopia Institute — claimed the decision violated environmental law. Farming has long been used on national wildlife refuges for multiple purposes like habitat restoration, which […]

(Beyond Pesticides, October 15, 2012) California’s Proposition 37, which would require mandatory labeling on genetically engineered (GE) foods, is facing a strong challenge as tens of millions of conventional food industry dollars have poured into television advertisements before the November 6th election. Poll results released Thursday by the Pepperdine University School of Public Policy and the California Business Roundtable show that 48.3% of respondents would vote yes for the measure on Nov. 6, while 40.2% would vote no. Prop 37 was authored by James Wheaton, president of the Environmental Law Foundation. Earlier this year, the California Right to Know campaign gathered 971,126 petition signatures for Prop 37, nearly double the 555,236 signatures required to qualify for inclusion on the ballot. As it currently stands, over 40 countries around the world, including all of Europe, Japan, and China have the right to know whether they are eating GE food. While opponents of the initiative are attempting to mislead the public about the costs of the proposition, an economic assessment from Joanna M. Shepherd-Bailey, Ph.D. of Emory University School of Law reveals that the initiative would not result in any additional expense to the taxpayers of California; Prop 37 is self-enforced and […]

(Beyond Pesticides, October 4, 2012) The Centers for Disease Control and Prevention (CDC) has released updated tables for its Fourth National Report on Human Exposure to Environmental Chemicals, which was released in 2009. The new data includes updated tables for 119 chemicals and tables for 34 new chemicals, including updates for 2,4-D and triclosan and their metabolites. New metabolites of organophosphorous insecticides are added for the first time. Notably, the report found that concentrations of four metabolites of organophosphates generally increased among nearly all groups CDC measured, while levels for two generally decreased. Organophosphate pesticides, such as chlorpyrifos, are highly toxic to humans and the environment. Chlorpyrifos is a frequent water contaminant and a long range toxicant, exposing communities and polluting pristine areas far from where it was applied. Volatilization drift ””the evaporation of the pesticide after application”” is also part of the problem for chlorpyrifos. A 2009 study found the pesticide to have significant impacts on the growth and development of amphibians miles away from the site where it was first applied. A USGS study in 2007 concludes that the breakdown products of chlorpyrifos are up to 100 times more toxic than the original. The Updated Tables, September 2012, […]

(Beyond Pesticides, October 3, 2012) A study published this week by Washington State University’s research professor Charles Benbrook, PhD, finds that the use of herbicides in the production of three genetically engineered herbicide-tolerant crops -cotton, soybeans and corn- has actually increased, contrary to industry claims that the technology would reduce pesticide applications. While Dr. Benbrook’s analysis is the first peer-reviewed, published estimate of the impacts of genetically engineered (GE) herbicide-tolerant crops on pesticide use, scientists have been raising the alarm over the mounting numbers of herbicide resistant weeds. This herbicide resistance finding, which contradicts chemical industry claims, is based on an exhaustive analysis of publicly available data from the U.S. Department of Agriculture’s National Agriculture Statistics Service. In the study, “Impacts of genetically engineered crops on pesticide use in the U.S. — the first sixteen years,” which appears in the peer-reviewed journal Environmental Sciences Europe, Dr. Benbrook writes that the emergence and spread of glyphosate-resistant weeds is strongly correlated with the upward trajectory in herbicide use. Marketed as Roundup and other trade names, glyphosate is a broad-spectrum systemic herbicide used to kill weeds. Approximately 95 percent of soybean and cotton acres, and over 85 percent of corn, are planted to […]

(Beyond Pesticides, September 21, 2012) A new French study reports that rats fed a diet of Roundup-tolerant genetically modified (GM) corn had an increased risk of developing tumors, suffering organ damage and dying prematurely. The study is the first animal feeding trial studying the lifetime effects of exposure to Roundup tolerant GM corn and has prompted the European Food Safety Authority to look into the study’s results. However, it is also being criticized by some other scientists who said the methodology was flawed and that other research had not found similar problems. The study, “Long term toxicity of a Roundup herbicide and a Roundup-tolerant genetically modified maize,” which is being published in the peer-reviewed journal Food and Chemical Toxicology, was led by Gilles-Eric Séralini, PhD, at the University of Caen in France. The study followed 200 rats for two years, the life-span of the rat, but far longer than the typical 90-day feeding studies used in regulatory assessments and subsequent approval of GM crops. The rats were fed different amounts of NK603 corn developed by Monsanto to be resistant to the herbicide Roundup. In some cases, the corn had been sprayed in the field with Roundup. Other rats were given […]

(Beyond Pesticides, September 18, 2012) Take Action! On September 25, EPA will close its public comment period for the petition requesting the agency to suspend the bee-killing pesticide clothianidin. The U.S Environmental Protection Agency (EPA) has failed to recognize that pollinators face unique hazards from clothianidin, a neonicotinoid pesticide which is linked to disruptions in bee mobility, navigation, and feeding behavior. So far thousands of concerned beekeepers, gardeners, hobbyists and folks like you have told EPA to suspend clothianidin and protect pollinators now! Without your support, clothianidin’s effects on honey bees will continue to put beekeepers, rural economies, and our food system at risk. With one in three bites of food reliant on honey bee pollination, it’s imperative that we act now! Tell EPA to suspend the use of the bee-killer clothianidin and protect pollinators. See sample comments here. If you are having trouble submitting to the docket, click here. Background Colony Collapse Disorder (CCD) is the name given to the mysterious decline of honey bee populations around the world beginning in 2006. On average, the U.S. Department of Agriculture (USDA) reports that beekeepers have been losing over 30% of their honey bee colonies each year—but some are losing many […]

(Beyond Pesticides, September 12, 2012) Expectant mothers exposed to the pesticide additive piperonyl butoxide (PBO), widely used in synthetic prethroid insecticides and those ending in “thrin” (popular in mosquito spray programs), during pregnancy pass to their children a heightened risk of noninfectious cough at ages 5 and 6, according to researchers at the Columbia Center for Children’s Environmental Health (CCCEH). These findings support the premise that children’s respiratory system is susceptible to damage from toxic exposures during the prenatal period. Researchers outfitted 224 expectant mothers with air monitors during their third trimester of pregnancy and measured the levels of PBO and permethrin in the air around them. Then, once the children were 5 and 6, the same two chemicals were measured from air samples collected inside their home. Results showed that children exposed to PBO in the womb were at increased odds of reporting cough unrelated to cold or flu. Researchers found no correlation between prenatal or childhood exposure to permethrin, however they pointed out that this may be because PBO is easier to measure in air samples than permethrin. Coauthor of the study, “Prenatal exposure to pesticide ingredient piperonyl butoxide and childhood cough in an urban cohort,” Dr. Rachel […]

(Beyond Pesticides, September 11, 2012) Lawn company giant, Scotts Miracle-Gro Co., pleaded guilty to numerous charges of misleading consumers with unapproved labels and falsifying insecticide registrations, including using toxic chemicals in wild bird food. Scotts was ordered to pay $12.5 million in criminal fines, the largest penalty ever set under the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA). Scotts admitted to using Storcide II and Actellic 5E to prevent insects from damaging the bird food in storage, even though it knew both chemicals were toxic to birds, fish, and other wildlife. In 2008, Scotts Miracle-Gro ceased sales of the tainted birdseed but not before 70 million units of the pesticide-tainted food was sold. The sentence imposed in federal court in Columbus, Ohio, includes a $4 million criminal fine, the Justice Department said. Separately, the company agreed to pay more than $6 million in civil penalties to the U.S. Environmental Protection Agency (EPA) and contribute $500,000 to organizations to protect bird habitats and restore and protect 300 acres of land to prevent runoff of pesticides into waterways —valued at $2 million. EPA has identified more than 100 products produced or sold by Scotts Miracle-Gro that violated the federal pesticide laws over […]

(Beyond Pesticides, September 7, 2012) Yesterday, Beyond Pesticides joined with the Center for Food Safety and the Sierra Club, along with beekeepers from around the country, to file a 60-Day Notice letter with the Environmental Protection Agency (EPA) announcing the intent to jointly sue the agency for Endangered Species Act (ESA) violations. The potential lawsuit highlights EPA’s continuing failure to ensure, through consultation with the U.S. Fish and Wildlife Service, that its numerous product approvals for the neonicotinoid insecticides clothianidin and thiamethoxam are not likely to jeopardize any federally-listed threatened or endangered species. “EPA has failed to uphold the clear standards of the Endangered Species Act,” said Peter Jenkins, attorney at the Center for Food Safety. “By continuing to ignore the growing number of reports and studies demonstrating the risks of neonicotinoids to honey bees and a large number of already threatened and endangered species, the EPA is exposing these already compromised populations to potentially irreversible harm.” The Notice of Intent to Sue follows a legal petition previously filed by several environmental organizations and more than two dozen beekeepers requesting that EPA immediately suspend use of the chemical clothianidin that poses fatal harm to pollinators. While refusing to issue an […]

(Beyond Pesticides, September 4, 2012) After considering comments from growers and other stakeholders, including over 2,000 emails generated from Beyond Pesticides’ supporters on the recent proposal to reverse a decision to end the use of the organophosphate insecticide azinphos-methyl (AZM), the U.S. Environmental Protection Agency (EPA) has once again come to the conclusion that the chemical presents health risks to workers and can cause negative ecological impacts, while effective alternatives to this insecticide are available to growers. The agency has decided to maintain the initial September 30, 2012 date for cancellation of the remaining uses of AZM, on apples, blueberries, sweet and tart cherries, parsley, and pears. Though this represents a victory for farmworkers and health and environmental advocates, EPA has decided to allow growers to use only existing stocks of AZM in their possession for another year, through September 30, 2013, citing unusually bad weather conditions throughout 2012. All the required mitigation measures now reflected on AZM labeling will remain in effect during this use. Distribution or sale of AZM after September 30, 2012 remains prohibited. Due to industry pressure, the agency initially announced that it was conducting a new risk-benefit analysis (analysis of the impacts of cancellation) and […]

(Beyond Pesticides, August 30, 2012) The U.S. Environmental Protection Agency (EPA) announced on August 17 that it is seeking comments on a proposal developed jointly with the U.S. Department of Agriculture (USDA), the National Marine Fisheries Service (NMFS), and the U.S. Fish and Wildlife Service (FWS) to enhance opportunities for stakeholder input during pesticide registration reviews and endangered species consultations. The proposal specifically emphasizes coordination across federal agencies and expanding USDA’s role, as well as pesticide users to provide current pesticide use information to EPA’s ecological risk assessments. The proposal describes EPA’s plan to reach out to potentially affected pesticide users to discuss the technical and economic feasibility of draft Reasonable and Prudent Alternatives (RPAs) intended to avoid jeopardy to threatened and/or endangered species. It also describes the process by which public comments received on RPAs will be summarized and organized by EPA and provided to the Services, which will prepare a document to be included in the administrative record of the consultation explaining how comments were considered, and if appropriate, how the final biological opinion was modified to address the comments. The Services will provide the document to EPA, and both the Services and EPA will make the document […]

(Beyond Pesticides, August 28, 2012) New research reveals that bats may be at greater risk from pesticide exposure than previously suspected. When foraging at dusk, bats can be exposed to agricultural chemicals by eating insects recently sprayed with pesticides. A study from the University of Koblenz-Landau in Germany reveals that bats, due to their long life span and tendency to only have one offspring at a time, are particularly sensitive to reproductive effects from pesticides. The study, “Bats at risk? Bat activity and insecticide residue analysis of food items in an apple orchard,” published in Environmental Toxicology and Chemistry, details the health effects of bats foraging on insects in an apple orchard after it was sprayed with the insecticides fenoxycarb and chlorpyrifos. After field applications of the pesticides, scientists measured the remaining chemical residues on flies, moths and spiders for two weeks. The highest residues were recorded on leaf dwelling insects and spiders, while lower contamination was found for flying insects. Based on this data scientists calculated exposure scenarios for different bat species, each with different feeding habits, and found that those which fed off insects from the leaves of fruit trees to be most affected. Researchers indicated that current […]

(Beyond Pesticides, August 27, 2012) A report published recently in the journal Weed Science has found that a population of the common weed waterhemp in Nebraska is resistant to the herbicide 2,4-D. The news comes as the U.S. Department of Agriculture (USDA) considers approving several new crops that have been genetically engineered (GE) for resistance to the herbicide. The report presents the latest in a long line of evidence that crops engineered for herbicide resistance are only pushing the problems of weed management further down the road. Researchers from the University of Nebraska found that half of the waterhemp samples they collected from a Nebraska field, after having been treated regularly for 10 years with 2,4-D,were no longer susceptible to applications of the herbicide. The experiments performed are described by Reuters: “After 10 years of treatment with 2,4-D, waterhemp was no longer effectively controlled in a Nebraska native-grass seed production field, the report said. The highest doses of 2,4-D that were used in an on-site field study were insufficient to control 50 percent of the waterhemp population. Researchers gathered waterhemp seeds from this field and performed greenhouse testing against a susceptible waterhemp variety. Twenty-eight days after treatment with the herbicide, […]
