(Beyond Pesticides, November 21, 2017) Both the active and inert ingredients in common herbicides induce antibiotic resistance in human pathogenic bacteria, according to the latest research from New Zealand scientists, published in Microbiology this week.  Previous research from the same team found in 2015 that commercial formulations of Roundup (containing glyphosate and inert ingredients) and Kamba (containing 2,4-D, Dicamba, and inert ingredients) caused antibiotic resistance to develop in Salmonella eterica and Escherichia coli, but this new research drills down into what ingredients in these formulations resulted in the effect. Lead author of the study, Jack Heinemann, PhD, University Canterbury’s School of Biological Sciences, explains that ultimately this research indicates that, “The sub-lethal effects of industrially manufactured chemical products should be considered by regulators when deciding whether the products are safe for their intended use,” Scientists parsed out the effects of individual active and inert ingredients by obtaining pure, technical grade dicamba, 2,4-D, and glyphosate, as well as the inert co-formulants “Tween80” and “CMC,” which are respectively, used to reduce surface tension and regulate the viscosity in a formulated herbicide, though also used as emulsifiers in foods like ice cream and in medicines. The technical grade herbicides were first applied to […]

(Beyond Pesticides, October 30, 2017) Tell the Arkansas State Plant Board to stand up to Monsanto, and protect farmers by banning dicamba’s use in Arkansas agriculture. Comment period closes today, Monday, October 30, 2017, at 4:30pm (Eastern Time). Your comments are needed to stop the disaster in Arkansas being created by Monsanto’s new genetically engineered (GE) cropping system, which relies on the toxic pesticide dicamba. If Arkansas bans dicamba, other states should and will follow —given the chemical industry’s takeover of the U.S. Environmental Protection Agency (EPA), which is allowing this extremely hazardous pesticide use. This is a problem that has regional and national implications, given the breakdown of the EPA and its pesticide program. We cannot let this failure of protection stand in Arkansas or anywhere in the country. Promoted by Monsanto as a way to address rampant Roundup (glyphosate) resistance, Monsanto’s new GE soybeans are now able to withstand both glyphosate and dicamba, an older herbicide with a range of documented health effects —from neurotoxicity to reproductive problems. Dicamba is also highly volatile and, as a result, has drifted across crop fields throughout the region, damaging high value fruit tree and organic operations. The Arkansas State Plant Board is […]

(Beyond Pesticides, October 20, 2017) Last week, the U.S. Environmental Protection Agency (EPA) announced that label changes to the herbicide dicamba would be made to try to minimize drift that has left thousands of acres of crops already damaged this season. The label changes include making dicamba “restricted use,” which allows only certified applicators to apply the chemical. Dicamba drift has been damaging farmers’ crops for at least two years due to the approval of new dicamba-tolerant genetically engineered (GE) crops. Advocates says that the new changes do not ensure that drift will be eliminated. According to EPA, the agency reached an agreement with the makers of dicamba, (Monsanto, BASF and DuPont) to restrict its application. This comes after hundreds of official complaints of crop damage related to dicamba across 17 states this year alone, leading to questions about the new formulation of the chemical used in genetically engineered (GE) crop productioon. New GE crops developed by Monsanto must be paired with specific formulations of dicamba, and thus led to a vast increase in dicamba use over the past couple growing seasons. Dicamba-based herbicide use has climbed dramatically as farmers have adopted, especially, Monsanto’s GE soybean seeds; in the 2017 season, 20 […]

(Beyond Pesticides, July 13, 2017) Over the past week, both Arkansas and Missouri issued bans on the sale and use of the weedkiller dicamba by farmers because of crop damage associated with the pesticide’s drift off treated fields. On Friday, July 7, the Arkansas Agriculture Department announced this emergency 120-day ban, which raised civil penalties for misuse of the toxic herbicide from $1,000 to a maximum of $25,000. The same day, the Missouri Department of Agriculture announced a temporary “Stop Sale, Use or Removal Order” on all dicamba products in the state labeled for agricultural use. Dicamba has been linked to damage of the kidney and liver, neurotoxicity, and developmental impacts. The chemical has a strong propensity to volatilize small particles of the herbicide into the air and drift far off-site. Sensitive crop species can be damaged by dicamba at levels in the parts per million. As of July 7, nearly 600 complaints of dicamba danage have been filed by Arkansas farmers in 23 different counties. In Missouri, as of July 3, there are 123 cases of dicamba injury complaints under investigation and according to the Missouri Soybean Association, “more than 200,000 Missouri soybean acres currently show signs of suspected dicamba […]

(Beyond Pesticides, June 12, 2017) Once again, there are reports that soybean and cotton fields are being damaged by off-site drift of the toxic herbicide dicamba. Last summer, farmers in Missouri, Arkansas, and Tennessee reported widespread crop damage from dicamba drift, which led to reduced yields. The U.S. Environmental Protection Agency (EPA) launched a criminal investigation at several Missouri locations into what they said was the illegal spraying of dicamba in October 2016. This year, reports of dicamba drift and damage are already being reported in Arkansas, and 25 formal complaints have already been filed, according to the state Plant Board. In summer 2016, illegal applications of dicamba damaged thousands of acres of soybeans, cotton, ornamental trees and fruits and vegetables. After numerous complaints, EPA launched a criminal investigation into the illegal spraying of dicamba, an investigation that is still ongoing. Many suspect that farmers who planted Roundup Ready 2 Xtend® and XTENDFLEX® Cotton, the new dicamba-tolerant genetically engineered (GE) seeds in the region, when faced with a proliferation of pigweed, illegally sprayed dicamba across their fields leading to drift and off-site crop damage to other farmers. This year, although it is too early to say how many acres have been affected or what specific […]

(Beyond Pesticides, January 27, 2016) Last week, farmers, environmentalists, and conservation groups filed a federal lawsuit that challenges the U.S. Environmental Protection Agency’s (EPA) approval of a new formulation of the toxic herbicide dicamba. The new formulation is called Xtendimax with Vapor Grip Technology, which is claimed to have lower volatility. The petitioners claim that EPA violated its duties under the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA) in issuing a conditional registration, and that it did not adhere to duties under the Endangered Species Act that require EPA to consult with the U.S. Fish and Wildlife Service to ensure registration would not harm any listed species. The organizations involved in the lawsuit are National Family Farm Coalition, Pesticide Action Network North America, Center for Food Safety, and Center for Biological Diversity, represented by legal counsel from Earthjustice and Center for Food Safety. Dicamba has caused a lot of controversy in the past. In August 2016, farmers in Missouri, Arkansas, and Tennessee confronted widespread crop damage and braced for lower yields as a result of agrichemical giant Monsanto’s botched roll-out of GE soybean and cotton crops. The company, whose current line of glyphosate-tolerant crops are failing to control weeds throughout […]

(Beyond Pesticides, January 5, 2017) Winegrowers in the Texas High Plains region are concerned that approval of new herbicides by the U.S. Environmental Protection Agency (EPA) will devastate their profitable industry due to chemical damage from pesticide drift. Wine producers in this region of Texas have witnessed chemical damage to their vineyards that they blame on the toxic herbicides, dicamba and 2,4-D, used on cereal crops and pastures on surrounding agricultural land. A new herbicide formulation containing dicamba, XtendiMax with VaporGrip Technology, was approved by EPA, and the agency has recently proposed to register and expand the use of Enlist Duo, a herbicide that contains 2,4-D. EPA’s final decision on registration of Enlist Duo is expected in early 2017. According to Paul Bonarrigo, owner of Messina Hof Winery in Texas, the “approval of these formulations will wind up affecting every vineyard up there.” This will have ramifications across Texas, as the wine industry contributed $1.88 billion to the state’s economy in 2013. Advocates say that the new herbicide formulations present unreasonable adverse risks to humans and the environment in addition to harming the livelihood of farmers. Following on these concerns, Garrett Irwin, owner of Cerro Santo vineyard, stated,“If we get […]

(Beyond Pesticides,  December 12, 2016)   On November 23, Bill Bader of  Bader farms, Missouri’s largest peach farm with over 1,000 acres and 110,000 peach trees, filed a suit against the multinational, agrichemical giant Monsanto. Mr. Bader seeks compensation for extensive damags to his peach trees, which he blames on the illegal, or non-labeled, use of the toxic herbicide dicamba, brought on by sales of Monsanto’s new, genetically engineered (GE), dicamba-tolerant crops. Mr. Bader is projected to lose $1.5 million in revenue from the crop damage. The case was filed in the Circuit Court of Dunklin County, an area that has been hit especially hard by alleged illegal dicamba spraying. The farm’s insurance company refuses to cover damages from any illegal herbicide use. Without compensation for the damages, the farm risks going out of business. The illegal use of dicamba in this case is not an isolated incident. There have been many disputes in the Midwest over the  illegal spraying of dicamba and subsequent crop damage due to pesticide drift.  Numerous news reports over the past two  months in southern soybean growing regions have found that many farmers are, in response to weeds on their farms that have become resistant […]

(Beyond Pesticides, December 2, 2016) Last week, the Arkansas Plant Board voted 12-0 to push measures that would ban or limit the use of certain forms of the toxic herbicide dicamba in the state. The hearing was called to address proposals that the board released for public comment on September 30, such as banning certain formulations of dicamba outright, creating restrictions on the time of year that other formulations of the herbicide can be used, and creating buffer zones in certain situations. This decision comes on the heels of a newly registered formulation of dicamba by the Environmental Protection Agency (EPA), and widespread reports of crop damage across the Midwest and Southeast due to the illegal use of dicamba before it was registered. According to DTN Progressive Farmer, the three-hour public meeting was packed with almost 200 people, and approximately 20 of those testified. The testimonies highlighted the disputes and tensions that have arisen over the use of dicamba, as many remembered and spoke about Mike Wallace, a farmer who was tragically murdered on October 27 during an argument with a fellow farmer in Missouri over the illegal use of the chemical and subsequent crop damage. “We’ve seen exactly what […]

(Beyond Pesticides, November 23, 2016)  With Thanksgiving just a day away, there is no better time to think about how we can more effectively join together as families and communities across divisions and different points of view to find a common purpose in protecting human health and the environment. Thanksgiving meals are commonly made with conventional agricultural products, which include a plethora of pesticides and genetically engineered (GE) ingredients that can affect  the health of consumers and agricultural workers alike. Read below to find out how you can combat the shortcomings of conventional agriculture with an organic Thanksgiving Day feast. Now, more than ever, it’s important to support organic and continue to demand agricultural practices that are protective of human and environmental health. According to GMO Inside, some common foods with GE ingredients purchased during Thanksgiving include: Campbell’s Tomato Soup, Wesson Canola Oil, Bruce’s Canned Yams, Hershey Milk Chocolate, Pepperidge Farm Crackers, Kraft Classic Ranch Dressing, Rice-a-Roni chicken flavored rice, Ocean Spray Cranberry Sauce, and Kraft’s Stove Top Stuffing. Glyphosate, produced and sold as Roundup by Monsanto, is the most commonly used chemical in the U.S., primarily as a weedkiller in chemical-intensive agriculture. Glyphosate has been  found to cause changes […]

(Beyond Pesticides, November 11, 2016) The U.S. Environmental Protection Agency (EPA) has registered a new formulation of dicamba to control weeds in cotton and soybean crops that have been genetically engineered (GE) to tolerate the chemical. The new formulation is called Xtendimax with VaporGripâ Technology, which is claimed to be specifically designed to have lower volatility. The registration, which is time-limited, will automatically expire after two years. According to the Center for Biological Diversity, EPA ignored the legal requirement to explore threats to endangered species, approving this new formulation without considering impacts to species protected under the Endangered Species Act. This decision comes directly after EPA announced that it is reapproving the toxic herbicide mixture Enlist Duo, and proposed to expand the number of crops and states in which it can be used. Dicamba has been linked to damage of the kidney and liver, neurotoxicity, and developmental impacts. The chemical has a strong propensity to volatilize small particles of the herbicide into the air and drift far off-site. Sensitive crop species can be damaged by dicamba at levels in the parts per million.  A study published by Pennsylvania State scientists in late 2015 found dicamba drift was “frequently responsible for […]

(Beyond Pesticides, October 26, 2016) The U.S. Environmental Protection Agency (EPA) has launched a criminal investigation at several locations in Missouri into the illegal spraying this summer of the herbicide dicamba. EPA’s investigation is ongoing and stems from widespread complaints of damage to various crops across Missouri and several other states in the Midwest and Southeast. Dicamba, a widely used herbicide, has had frequent problems with drift and subsequent crop injury. Many suspect that  farmers who planted the new dicamba-tolerant genetically engineered (GE) seeds in the region, when faced with a proliferation of pigweed this year, illegally sprayed dicamba across their fields, leading to drift and off-site crop damage to other farmers. While USDA has deregulated (approved) dicamba-tolerant crops, EPA is expected to but has not yet registered a formulations of dicamba for use on GE crops. Dicamba is highly volatile and prone to drift. In a statement to the Arkansas Democrat-Gazette, EPA’s Region 7 office said the Missouri Department of Agriculture received more than 100 complaints since June 22, 2016. The complaints allege damage to more than 41,000 acres of soybeans, and other crops including peaches, tomatoes, watermelons, cantaloupe, rice, purple-hull peas, peanuts, cotton and alfalfa; as well as […]

(Beyond Pesticides, August 9, 2016) Farmers in Missouri, Arkansas, and Tennessee are confronting widespread crop damage and bracing for lower yields as a result of agrichemical giant Monsanto’s botched roll-out of new genetically engineered soybean and cotton crops. The company, whose current line of glyphosate-tolerant crops are failing to control weeds throughout the U.S. and across the globe, developed a new line of soybean and cotton with traits that make it tolerate applications of an older herbicide dicamba. However, while its seeds are available for purchase on the market, and Monsanto is encouraging farmers to grow them, the company has yet to receive EPA regulatory approval for the dicamba herbicide meant to be used with the plants. A spate of news reports over the past two  months in southern soybean growing regions finds that many farmers are illegally applying off-label dicamba-based herbicides to Monsanto’s new GE crops in an effort to control weeds resistant to glyphosate. Use of this highly volatile herbicide is causing widespread crop damage not only to soybeans that don’t carry the resistance trait, but other crops in the region, including peaches, melons, and tomatoes. Dicamba has a strong propensity to volatilize small particles of the herbicide […]

(Beyond Pesticides, July 29, 2016)  A study released earlier this week finds lower IQ (intelligence quotient) in children born to mothers who during their pregnancy were living in close proximity to chemical-intensive agricultural lands where organophosphate pesticides were used. This study adds to the body of scientific literature that links prenatal exposure to organophosphate pesticides with lower IQ’s in children. Organophosphate pesticides, a relatively older generation of highly neurotoxic pesticides still widely used on farms in California, have been associated with a  broad range of diseases  in both children and adults.  This  latest study  supports health and environmental advocates’ call to eliminate these toxic pesticides in agriculture and move toward safer, sustainable, and organic management practices. The study, titled  Prenatal Residential Proximity to Agricultural Pesticide Use and IQ in 7-Year-Old Children, looks at 283 women and children from the agricultural Salinas Valley who are enrolled in the long-term Center for the Health of Mothers and Children in Salinas (CHAMACOS) study. Specifically, researchers looked at pregnant women living within one kilometer of agricultural fields where organophosphate pesticides were used. They found that at age 7, the children of those women had declines of approximately two IQ points and three verbal reasoning […]

(Beyond Pesticides, December 10, 2015) Researchers at Pennsylvania State University (Penn State) and the Pennsylvania Association for Sustainable Agriculture published a study, which found that aerial drift of the herbicide dicamba adversely affects non-target plants and pollinator species. Dicamba is a chlorinated benzoic acid herbicide associated with neurotoxicity and reproductive effects. The study used alfalfa crops to track the flowering and floral visitation by insects, specifically pollinators, after applications of sublethal doses of dicamba. The researchers concluded, “Our results suggest that widespread non-target damage from these herbicides may adversely affect pollinator communities.” Because dicamba is “frequently responsible for sublethal, off-target damage” to plants and insects, Penn State researchers assessed the most common route of exposure: particle and vapor drift. In its  study, Effects of the Herbicide Dicamba on Nontarget Plants and Pollinator Visitation, the research team examined the crop species alfalfa (Medicago sativa), which requires insect pollination to produce seeds, and the native plant species common  boneset (Eupatorium perfoliatum), which is highly attractive to a wide range of pollinator species. The researchers applied a range of sublethal doses of dicamba to the plants, then tracked flowering and floral visitation by insect species. They identified the types of insects visiting the […]

(Beyond Pesticides, March 30, 2015) Last week, following the World Health Organization’s (WHO) declaration that glyphosate is carcinogenic to humans  based on animal studies, a new study was published in the American Society of Microbiology’s journal, mBio, linking glyphosate, 2,4-D and dicamba to antibiotic resistance after testing the sub-lethal effects of these pesticides in certain bacteria. The new mBio study finds  that when bacteria, specifically Salmonella and E. coli, are exposed to the herbicides described above, they responded differently to the common antibiotics ampicillin, ciprofloxacin, chloramphenicol, kanamycin, and tetracycline. Researchers replicated real-world scenarios by purchasing weed killers from a local store and using the exact levels that are specified on the product label. This provided researchers with the opportunity to observe how the bacteria reacted when exposed to the herbicides at sublethal levels; that is, those that did not kill them. When the bacteria are exposed to the herbicides and the antibiotics at the same time, the exposure to the herbicides trigger a defense mechanism that otherwise would not have been triggered solely by the antibiotics. This defense mechanism seeks to rid the bacteria of toxins and is non-specific, which means while it builds resistance to the toxic effects of […]

(Beyond Pesticides, January 13, 2015) Over a decade after consumer opposition halted multinational agrichemical business Monsanto’s plans to develop genetically engineered (GE) herbicide-resistant wheat, the company is trying again. This time, Monsanto’s goal is to create wheat that is resistant to three different herbicides; glyphosate, glufosinate, and dicamba. Although over 90% of corn, soybean, and cotton grown in the United States are GE, no GE wheat is currently allowed to be planted. In 2013, a farmer in Oregon discovered the presence of Monsanto’s original Roundup-Ready wheat, developed to be resistant to glyphosate, in his field despite the company’s plans to abandon the strain and claims to have destroyed the crop  a decade earlier. The company had restarted extensive field trials back in 2011. An investigation by the U.S. Department of Agriculture (USDA) determined that the contamination was an “isolated incident.” It was unable to determine exactly how the wheat came to grow in the Oregon farmer’s field. However, shortly after the agency closed its investigation, another farmer in Montana detected the GE strain in his wheat fields. The recurrence of this incident reveals the contamination event not to be an isolated incident. It instead demonstrates the threat that these crops […]

(Beyond Pesticides, October 8, 2014) After headliners like genetically engineered (GE) Roundup-Ready corn and soybeans failed to deliver on claims of decreased pesticide use and environmental sustainability, instead leading to the rise of “superweeds,” the U.S. Department of Agriculture approved more dangerous, 2,4-D-resistent versions   shortly after. Now after the predictable failure of Roundup-Ready cotton, USDA is set to approve dicamba-tolerant GE cotton, coming soon to a t-shirt near you.   Feeling a bit itchy now? Join us in telling USDA the solution to “superweeds” is NOT more GE crops and increased herbicide use! Act by October 10, at midnight! USDA’s proposal to deregulate and allow into the environment yet another GE variety will inevitably lead to damaging effects on non-GE crops, native plant species, and environmental biodiversity. USDA acknowledges that the purpose of dicamba-tolerant cotton “is to provide growers with an additional in-crop weed management option to manage [glyphosate resistant] broadleaf weed species,” but introducing crops resistant to other chemical technologies like dicamba may provide short-term relief from resistant weeds, but is not a long-term, sustainable solution to burgeoning weed resistance. This current proposal also includes dicamba-tolerant soybean, as well as a stacked tolerance to the herbicide glufosinate. Contrary […]

(Beyond Pesticides, September 19, 2014) The pesticide treadmill continues to turn with the U.S. Department of Agriculture’s (USDA) recent approval this week of three 2,4-D-tolerto ant corn and soybean crops, developed by Dow AgroSciences. Some growers have been pushing for the new Enlist crops in order to combat the rapid proliferation of glyphosate-resistant weeds. The use of glyphosate, the active ingredient in Monsanto’s Roundup formulation, on genetically-engineered (GE) crops has proven to be an abject failure due to widespread weed resistance. So widespread is this resistance that the U.S. Environmental Protection Agency (EPA) has  granted an emergency use exemption  for fluridone, which does not have registered uses in agriculture.  More recently, Texas regulators requested the use of propazine to combat glyphosate-resistant Palmer amaranth, or pigweed, which EPA recently denied,  citing risks to drinking water and other hazards.   Even though the agency denied the emergency use application, it accepted the argument put forth by the Texas Department of Agriculture that  glyphosate-resistant weeds in three million acres of herbicide-tolerant cotton constituted an  “urgent non-routine situation.”  Beyond Pesticides argued to EPA that the weed resistance in  herbicide-tolerant cropping systems is very predictable and has become routine, thus disqualifying states from using the […]

(Beyond Pesticides, August 8, 2014) Despite the continued documentation of weed resistance all over the United States, as well as the world, another line of herbicide-tolerant crops developed by Monsanto is currently in the pipeline awaiting likely approval by U.S. regulators. The U.S. Department of Agriculture’s (USDA) Animal and Plant Health Inspection Service (APHIS) released a draft environmental impact statement (EIS) on Tuesday, which, according to regulators, will pave the way for the approval of new  genetically modified cotton and soybean plants tolerant to a mixture of the herbicides glyphosate and dicamba. Monsanto’s new soybean and cotton crops were developed to withstand their new herbicide formulation, called Roundup Xtend, which combines the pesticides dicamba and glyphosate. The “Roundup Ready Xtend crop system” was developed to curb the proliferation of millions of acres of weeds that have grown resistant to Monsanto’s glyphosate-based Roundup, which has been used on the company’s biotech corn, soybeans, and cotton. Weed resistance due to cropping systems dependent on herbicides has been documented for years, making APHIS’ conclusions in the EIS all the more alarming. A report that Beyond Pesticides published 12 years ago, “The Environmental Risks of Transgenic Crops: An Agroecological Assessment is the failed pesticide […]

(Beyond Pesticides, May 14, 2013) The U.S. Department of Agriculture (USDA) has determined that environmental impact statements (EIS) are required for Dow and Monsanto’s   new genetically engineered (GE),  2,4-D resistant crops.  According to Reuters, Dow had anticipated that their new crop would be on market by year’s end. Monsanto released a statement calling the move “unexpected.” USDA’s Animal and Plant Health Inspection Service (APHIS) is requiring the reviews in response to overwhelming concern expressed by farmers, consumers, and public health officials during the comment period for these new herbicide-resistant crops. Dow’s new GE corn, dubbed “Enlist,” tolerates repeated applications of both glyphosate and the powerful herbicide 2,4-D, while Monsanto’s GE cotton and soybean (produced in partnership with their “competitor,” agrichemical giant BASF)  is resistant to the herbicide dicamba. Both companies champion their crops as solutions to the widespread occurrence of weeds resistant to glyphosate, the active ingredient in Monsanto’s Roundup herbicide, even though the ultimate cause for this resistance can be traced to overuse of the chemical on “Roundup-Ready” crops. A 2011 study in the journal Weed Science found at least 21 different species of weeds to be resistant to applications of Monsanto’s Roundup. Even without the presence of […]

(Beyond Pesticides, May 15, 2012) Dow AgroSciences and Monsanto have filed paperwork for Canadian approval of corn and soybeans genetically engineered (GE) to withstand heavy applications of potent herbicides, reports the Ottawa Citizen. The chemical companies are seeking Health Canada and Canadian Food Inspection Agency assessments for the introduction of four varieties of GE corn and soybeans engineered to tolerate the highly toxic herbicides 2,4-D and dicamba. In the U.S., the federal Department of Agriculture (USDA) is in the process of reviewing Dow’s application for its 2,4-D-tolerant corn, as well. Beyond Pesticides and others recently submitted comments to USDA challenging this approval. Dow’s GE corn is modified to be tolerant to 2,4-D, which is contaminated with dioxin and linked to cancer, birth defects, and more. The company is introducing the new GE corn variety because weeds are becoming resistant to Roundup, the previous chemical of choice for herbicide-tolerant plants. However, solving herbicide resistance with a new, more toxic chemical is like using gasoline to put out a fire. It will cause even more damage to health and the environment, and in a few years, the pesticide industry will be marketing their next “solution” to the growing resistance problem. Dow states […]

(Beyond Pesticides, November 7) Once heralded as a breakthrough for reducing the rates and toxicity of the pesticides applied by farmers, genetically engineered (GE) crops are perversely leading to renewed dependency on the very herbicides they were claimed to make obsolete. Growing recognition that pervasive planting of “Round-Up Ready” corn, soybeans and cotton is accelerating weed resistance is prompting GE seed companies to rush to market ‘stacked’ varieties that are resistant to additional herbicides, including 2, 4-D and dicamba. Farmers planting the stacked varieties will be spraying these older herbicides in addition to glyphosate, which most commodity crops have already been engineered to tolerate. Professor David A. Mortensen of Pennsylvania State University has estimated that adoption of Round-Up Ready and 2, 4-D or dicamba resistant stacked varieties in soybeans could result in a 70% increase in herbicide use in a relatively short time. The St. Louis Pots-Dispatch reported on progress that multinational chemical corporations Dow AgroSciences, BASF, and Monsanto are making to bring multi-herbicide resistant varieties to market. Under separate arrangements with each company, Monsanto adds glyphosate resistance to seeds that are simultaneously engineered to resist other herbicides. In October, Dow AgroSciences obtained a global patent on its Enlist Duo […]
