(Beyond Pesticides, December 07, 2015) Monsanto will be put on trial for crimes against nature, humanity, and ecocide in The Hague, Netherlands, home to the United Nation’s International Court of Justice. The Organic Consumers Association (OCA), IFOAM International Organics, Navdanya, Regeneration International (RI), and Millions Against Monsanto, joined by dozens of global food, farming and environmental justice groups announced late last week that they will put the U.S.-based transnational corporation on trial next year on World Food Day, October 16, 2016. The announcement was made at a press conference held in conjunction with the COP21 United Nations Conference on Climate Change, November 30 — December 11, in Paris. Monsanto is the producer of Roundup, a widely-used herbicide that contains the active ingredient glyphosate, a chemical that was recently classified as a cancer-causing agent based on laboratory studies by the International Agency for Research on Cancer (IARC), the specialized cancer agency of the World Health Organization (WHO). The corporation has developed and produced many other toxic chemicals, including: Lasso, an herbicide that is now banned in Europe; PCBs (polychlorinated biphenyl), one of the 12 Persistent Organic Pollutants (POP) that affect human and animal fertility; and 2,4,5 T (2,4,5-trichlorophenoxyacetic acid), a dioxin-containing […]

(Beyond Pesticides, November 13, 2015) Research finds that sound waves could combat the Asian citrus psyllid, an insect that has been devastating Florida orange groves, and possibly reduce the need for pesticides. The Asian citrus psyllid carries a bacteria that causes “citrus greening,” an incurable disease with symptoms that include yellow shoots, uneven discolored patches, and deficiencies with the production of chlorophyll, green pigment found within plants. To stem the spread of the disease  —which is responsible for an estimated $3.63 billion in lost revenue from orange juice for the state of Florida from 2006-2012— researchers at the U.S. Department of Agriculture (USDA) and University of Florida (UF) are developing vibration traps that hijack psyllid mating calls to locally bring their populations under control. “We’re trying hard to cut down on use of pesticides in orange groves, partly because we are worried they’ll build up resistance to pesticides, and that will make things even worse,” said Richard Mankin, Ph.D., a research entomologist with USDA. He presented  findings  on acoustic disruption at the meeting of the American Acoustical Society  last month in Jacksonville. When a male Asian psyllid is looking for a mate, he situates himself on a twig and alerts […]

(Beyond Pesticides, October 22, 2015) With increasing consumer concern about genetically engineered (GE) food, yesterday  the U.S. Senate Committee on Agriculture, Nutrition, and Forestry held a hearing,  entitled Agriculture Biotechnology: a Look at Federal Regulation and Stakeholder Perspectives, that critics called lopsided. Most witnesses characterized GE food as safe or side-stepped the issue of safety, as government witnesses refused to distinguish GE from conventional food and opposed food labeling. “This is the first time in 10 years we’ve had a hearing on biotech. I guess we’re a little late, but we’re here,” said chair of the committee, Senator Pat Roberts (R-KS). The ranking  minority member of the committee, Senator  Debbie Stabenow (D-MI)  said,  “Biotechnology is proven to be safe, beneficial, and I believe will play a major role in helping to solve these dual global challenges of climate change and global food security,” Central to the hearing is the the issue of labeling food products containing GE crops. Senator Stabenow called for the adoption of legislation on GE food labeling, presumably with language that will preempt the authority of states to adopt more stringent labeling standards. Senator Stabenow said that she wants labeling that “doesn’t stigmatize biotechnology.” The GE food […]

(Beyond Pesticides, June 24, 2015) The International Agency for Research on Cancer (IARC) has found that there is some evidence in experimental animals that the popular herbicide, 2,4-D, is linked to cancer and now classifies it as a Group 2B, “possibly carcinogenic to humans.” IARC also classified lindane, used commonly in the U.S. as a topical lice treatment, in Group 1,“carcinogenic to humans” based on sufficient evidence in humans with the onset of non-Hodgkin lymphoma (NHL). These latest cancer findings come just months after the agency classified the world’s most widely used herbicide, glyphosate (Roundup), as “probably carcinogenic to humans,” raising public concerns on the lack of action from U.S. regulators. This month, 26 experts from 13 countries met at the World Health Organization’s (WHO) IARC in Lyon, France to assess the carcinogenicity of the insecticide lindane, the herbicide 2,4-D, and insecticide DDT. The findings are published in the Lancet. The new IARC findings come months after the agency classified glyphosate, the ingredient in the popular Roundup weed killer, as a Group 2A “probable” carcinogen, citing sufficient evidence of carcinogenicity based on laboratory studies. This decision sparked renewed calls for the U.S. Environmental Protection Agency (EPA) to take action on […]

(Beyond Pesticides, June 23, 2015) After years of denial and obstruction, Air Force and Air Force Reserve veterans now have the chance to receive compensation for their exposure to the highly toxic herbicide Agent Orange on contaminated aircraft used after the Vietnam War. Affected veteran’s health issues stem from their time spent on UC-123 transport planes, which during the war were outfitted with spray equipment in the American military’s attempt to eliminate forest cover for Vietcong fighters. After the war, these aircraft were returned to use in the United States for basic transport operations such as cargo shipping and medical evacuation missions. However, these planes never underwent any form of decontamination or testing before being repurposed. Though the Agent Orange Act of 1991 stipulated medical care and disability coverage for sick veterans who  served in the Vietnam War and were exposed to Agent Orange, those who flew in contaminated post-war planes were deemed ineligible. Prior to this recent announcement from the Department of Veteran’s affairs, government officials asserted that the “dried residues” of Agent Orange were not likely to pose a health threat to aircraft crew. However, a study published by the National Academy of Sciences Institute of Medicine in […]

(Beyond Pesticides, April 22, 2015) A coalition of conservation, food safety, and public health groups filed a motion Monday challenging the U.S. Environmental Protection Agency (EPA)’s decision to expand the use of “Enlist Duo” on genetically engineered (GE) corn and soybean crops to nine additional states: Arkansas, Kansas, Louisiana, Minnesota, Missouri, Mississippi, Nebraska, Oklahoma, and North Dakota. Enlist Duo, which contains the toxic herbicide, 2,4-D, was approved by EPA to be used on 2,4-D-resistant crops, despite concerns for human and environmental contamination. The motion was filed in the United States Ninth Circuit Court of Appeals by Earthjustice and Center for Food Safety on behalf of Beyond Pesticides, Center for Biological Diversity, Center for Food Safety, Environmental Working Group, the National Family Farm Coalition, and Pesticide Action Network North America. This motion builds on the coalition’s earlier challenge of Enlist Duo, which already includes six Midwestern states where EPA previously first approved the herbicide’s use on GE corn and soybean crops. Another legal challenge cites EPA’s  failure to consult with the U.S. Fish and Wildlife Service (FWS) regarding the impact of the herbicide on two endangered species —the whooping crane and the Indiana bat— with the approval of Enlist Duo for […]

(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, May 15, 2014) Last week, the U.S. Department of Agriculture (USDA) announced  that it is broadening the use of tiny parasitic wasps, Tamarixia Radiata, to combat the rampant problem  of Huanglongbing, also known as citrus greening disease, which has killed thousands of orange trees in Florida. The citrus industry is valued at $2 billion dollars. Citrus greening is an incurable disease that is spread by the Asian citrus psyllid. Symptoms of this disease include yellow shoots, uneven discolored patches, and deficiencies with chlorophyll production. Chlorophyll is the green pigment found within plants. It is extremely important for photosynthesis, which allows plants to absorb energy from the sun. The disease is usually found in warmer climates like Asia, India and the Saudi Arabian Peninsula; however, it made its way to Florida in 1998 and is now endangering California’s citrus industry. USDA has already committed to provide $1.5 million dollars to the T. radiata  breeding and release program in California, Texas, and Florida. Congress has also allocated more than $125 million dollars over the next five years to fund more research on containing the spread of the Asian citrus psyllid. Although the psyllids do not directly kill citrus trees, they […]

(Beyond Pesticides, February 28, 2014) A report released last week by the U.S. Department of Agriculture (USDA) considers the trends of genetically engineered (GE) crops over the past 15 years, since they were first introduced. Responding to increasing GE use, USDA also points to major concerns such as increasing herbicide resistance and higher levels of herbicide use as major potential threats to human health and the environment. The report comes as USDA and the U.S. Environmental Protection Agency (EPA) are poised to  approve  new forms of GE corn and soybeans designed to be resistant to 2,4-D products,  one of the active ingredients in Agent Orange and a known carcinogen. Released  by USDA’s Economic Research Service (ERS) on February 20, the report not only details the trends in GE use but also the known and unknown threats that GE crops pose. The number of GE varieties approved by USDA’s Animal and Plant Health Inspection Service (APHIS) grew exponentially between 1984 and 2002, the report said. Today the majority of GE crops, corn and soy, are grown on the nation’s largest farms. In 2013, more than 169 million acres of GE crops were planted in the U.S., comprising half of all cropland. […]

(Beyond Pesticides, February 25, 2014) During the Vietnam War, over 10 million pounds of the toxic herbicide Agent Orange were applied from military aircraft to defoliate forests and destroy civilian crops. Outfitted with spraying equipment, UC-123 transport planes played a major role in the American military’s campaign to eliminate forest cover for Vietcong fighters. After the war, these aircraft were returned to use in the United States for basic transport operations such as cargo shipping and medical evacuation missions. However, these planes never underwent any form of decontamination or testing before being repurposed for use back in the states. Although the U.S. Air Force and Department of Veteran Affairs have asserted that “dried residues” on these aircraft were not likely to pose a health threat to aircraft crew – a justification used to deny sickened veterans medical support, a new study from the journal Environmental Research finds strong evidence of health risks from residual exposure. The study, Post-Vietnam military herbicide exposures in UC-123 Agent Orange spray aircraft, modeled flight crew’s potential exposure to dioxin, a contaminant in Agent Orange and a  highly potent carcinogen. Scientists based their models on monitoring tests that found dioxin contamination in the mid-1990’s and late […]

Beyond Pesticides, January 28, 2014) In the latest attempt to suppress the voice of local communities and scuttle the implementation of laws to protect health and the environment, last week a bill was introduced in the Hawaii State House of Representatives that will preempt (block) local governments from restricting the use of hazardous pesticides and genetically engineered (GE) crops. Though House Bill 2506 is being promoted as the expansion of the state’s “Right-to-Farm Act,” the bill will prevent the implementation of new laws recently passed in Kauai and Hawaii County. Kauai Councilman Gary Hooser explained to The Garden Island, “Both of these bills take away 100 percent of the authority of the county to regulate agriculture, which includes pesticides. It is without question an attempt to nullify Ordinance 960 (formerly Bill 2491), as well as the ordinance passed on the Big Island.” Local communities in the Hawaiian Islands fought a number of hard-won battles last year against intrusions by agrichemical companies spraying pesticides and planting GE crops near where they work, live, and go to school. After massive outpourings of public support, numerous late-night council sessions, and overcoming a mayoral veto, Kauai County passed Bill 2491. Kauai’s Ordinance 960 requires […]

(Beyond Pesticides, January 6, 2014) The U.S. Department of Agriculture (USDA) Friday released for public input its Draft Environmental Impact Statement (DEIS), which calls for the deregulation of genetically engineered (GE) corn and soybeans engineered to be tolerant to the toxic herbicide 2,4-D. These new varieties of GE corn and soybean, created partly due to proliferate weed resistance resulting from the widespread use of glyphosate (Roundup) on other GE crops, is set to usher in dramatic increases in 2,4-D use with associated health and environmental hazards, according to environmental scientists. The GE crops are being produced by Dow AgroSciences under the brand name “Enlist.” According to Nichelle Harriott, senior scientist at the national environmental group Beyond Pesticides, “The engineered varieties will not only spawn new weed resistant strains, but contaminate the environment and increase the public health risks to cancer and Parkinson’s disease, especially in farmworkers and farming communities exposed to 2,4-D.” The failure of GE-glyphosate (Roundup) tolerant crops to live up to their promises is a main contributing factor behind the development of stacked varieties such as “Enlist,” which combines resistance to 2,4-D and glyphosate. So widespread is glyphosate resistance that EPA has granted emergency use exemptions for pesticides […]

(Beyond Pesticides, December 17, 2013) A new rule proposed by the U.S. Food and Drug Administration (FDA) requires manufacturers of antibacterial hand soaps, body washes, and other consumer goods to prove that their products are both safe for long-term use and more effective than regular bar soap in order to remain on the market. This announcement, though long-delayed, represents a positive step towards reining in the unnecessary use of antibacterial chemicals at a time when top-level government scientists at the U.S. Centers for Disease Control and Prevention (CDC) have asserted that we’ve reached “the end of antibiotics.”  With the publication of its article The Ubiquitous Triclosan: A common antibacterial agent exposed  in 2004, Beyond Pesticides began a campaign to ban triclosan because of it cross resistance with antibiotics, endocrine disrupting effects, and lack of benefits. “Numerous studies have shown that antibacterial soaps cause more harm than any of their perceived benefits,” said Nichelle Harriott, staff scientist  at Beyond Pesticides. “For the protection of human health and the environment, we urge the FDA to move quickly to get these products off of the market.” FDA’s new rule, announced Monday, will be open for public comment for 180 days and manufacturers will […]

(Beyond Pesticides, October 22, 2013) Nearly a week after plant geneticists from the world’s largest agrichemical companies accepted the World Food Prize, an Associated Press (AP) investigation links the effect of their work to soaring pesticide use and resulting health problems.  According to the  AP, the advent of “no-till” farming methods in Argentina with the use of genetically engineered (GE) crops and companion pesticides has caused significant health impacts in farming towns abutting GE fields. Since the introduction of these practices in Argentina by agrichemical companies such as Monsanto, cancer rates have skyrocketed and the number of birth defects has quadrupled. Argentina was an early adopter of GE technology in 1996, when it was billed as the silver bullet to solve world hunger with increased crop  productivity, and improved human and environmental health resulting from decreased pesticide use. The most widely used GE crops, such as Monsanto’s Roundup Ready line of corn and soybeans, allow farmers to apply the herbicide glyphosate during and after seed plantings in order to kill weeds without risk of the main crop dying off. Today, almost all the corn, soy, and cotton produced in the country are GE. As the  AP reports, and researchers in […]

(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, April 8, 2013)  Given the rise of targeted plant and animal pests that are resistant to the tactics of the biotechnology industry, companies that produce genetically engineered (GE) crops have begun producing plants with “stacked” traits. For herbicide resistant crops, this means adding traits that incorporate crop resistance to increasingly dangerous and toxic chemicals, such as 2,4-D, a major component in the Vietnam-era herbicide Agent Orange. For crops engineered to produce their own natural insecticide, namely the toxin Bacillus thuringiensis, this means adding new formulations of the bacterium. Although this practice is widely considered acceptable and effective by the biotechnology industry, a new study from the University of Arizona College of Agriculture and Life Sciences, published in the journal PNAS, casts doubt on this assumption. Most scientists assume that two-toxin plants will be more durable than one-toxin plants. The extent of the advantage of the pyramid strategy, however, rests on assumptions that are not always met, the study reports. “The pyramid strategy has been touted mostly on the basis of simulation models,” said Yves Carrière, PhD, lead author of the study. “We tested the underlying assumptions of the models in lab experiments with a major pest of corn […]

(Beyond Pesticides, February 22, 2013) The U.S. Department of Agriculture (USDA) has invited the public to submit comments concerning changes to organic standards being proposed by the National Organic Standards Board (NOSB), which will be voted on at the Board’s spring meeting on April 9-11,2013 in Portland, OR.

(Beyond Pesticides, January 8, 2013) Neurologists at the University of California, Los Angeles (UCLA) have published their latest research linking pesticide exposure to Parkinson’s disease. Appearing in the online edition of PNAS, the UCLA scientists’ work details the series of events that can occur after individuals are exposed to the pesticide benomyl, which was phased out in 2001. Researchers believe their findings on the series of events the pesticide sets in motion could be applicable even to Parkinson’s patients who have not been exposed to benomyl. According to scientists, exposure to benomyl prevents the enzyme aldehyde dehydrogenase (ALDH) from keeping in check a naturally occurring toxin in the brain called 3,4-Dihydroxyphenylacetaldehyde (DOPAL). Without ALDH regulating DOPAL, the toxin accumulates, damages neurons, and increases an individual’s risk of developing Parkinson’s disease. Researchers postulate that this process may be occurring in people with Parkinson’s who were never exposed to pesticides. The findings of this research provide insight into possible treatments to slow the disease, such as developing new drugs to protect ALDH activity. Although the exact cause of Parkinson’s is still unknown, until this research scientists were focusing in on the protein a-synuclein as a pathway to the disease. The protein, present […]

(Beyond Pesticides, November 14, 2012) For years, scientists have shown that pesticide exposures are linked to the onset of Parkinson’s disease. Now a new study by researchers at University of California, Los Angeles, (UCLA) finds that exposure to pesticides and suffering a head injury are associated with a three-fold increase in one’s chances of developing Parkinson’s disease. Parkinson’s disease is the second most common neurodegenerative disease, and occurs when nerve cells in the substantia nigra region of the brain are damaged or destroyed and can no longer produce dopamine, a nerve-signaling molecule that helps control muscle movement. People with Parkinson’s disease have a variety of symptoms, including loss of muscle control, trembling and lack of coordination. Over time, symptoms intensify. At least one million Americans have Parkinson’s and about 50,000 new cases are diagnosed each year. The study, “Traumatic brain injury, paraquat exposure, and their relationship to Parkinson disease,” published in the journal Neurology surveyed more than 1,000 adults ages 35 and older who lived in central California. Some 357 of the participants were diagnosed with Parkinson’s disease. Participants with the disease were nearly twice as likely as those without the disease to report having had a head injury in […]

(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 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, 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, […]
