(Beyond Pesticides, April 25, 2018) A class-action lawsuit against two manufacturers of neonicotinoid insecticides is moving ahead in Quebec, Canada after an appeal to block the case by the Canadian government and the chemical companies, Bayer and Syngenta, was dismissed. In February 2018, the case, brought by a beekeeper, was allowed to proceed to trial by the Quebec Superior Court. Quebec queen bee breeder, Steve Martineau, conducted tests on water and his dead and dying bees and found traces of neonicotinoids. His suit alleges that Bayer and Syngenta were negligent in the manufacture and sale of neonicotinoids in Quebec, and are responsible for damages that he and other class members suffered under Article 1457 of the Quebec Civil Code. Bayer and Syngenta challenged the application on a number of grounds including the assumption that they had manufactured the neonicotinoids which killed Martineau’s bees. The class in this case was authorized for all persons in Quebec who own or owned bees in the affected area since 2006. Mr. Martineau estimates he has lost about $20,000 a year to present due to the effects of neonicotinoids on his bee population (Martineau v. Bayer CropScience Inc. CALN/2018-007) “We’re suing on behalf of Quebec beekeepers whose bees were […]

(Beyond Pesticides, April 2, 2018) The comment period closes Wednesday, April 4 at 11:59 pm for the Spring 2018 National Organic Standards Board (NOSB) Meeting. Decisions governing the substances allowed in organic food production are subject to public input twice a year. Public participation in this process is critical to the quality of the decisions and meeting both consumer and farmer expectations. In this context, Beyond Pesticides analyzes the proposals before the NOSB, shares its analysis and comments with the public, and urges people to engage the process and make their views known to decision makers. Details are provided below. In addition to the other priorities in our previous alert (preventing fraud in organic, removing incentives to convert native ecosystems to organic crop production, and the use of bisphenol A [BPA] and other chemicals in organic packaging), we focus attention here on some genetic engineering (GE) issues, contaminated inputs, and “inert” ingredients.

(Beyond Pesticides, March 30, 2018) While conventional farming practices rely primarily on new sources of synthetic nitrogen fertilizer to grow crops, organic agriculture conserves nitrogen by using recycled sources, as detailed by new research published by the University of Virginia (UVA) and The Organic Center. Of concern is â€reactive nitrogen,’ which is nitrogen in a form that will eventually be used by plants (ex. nitrous oxide (N2O), nitrate (NO3–), nitrite (NO2–), ammonia (NH3), and ammonium (NH4+)), rather than benign, non-reactive nitrogen in the form of N2. “This research is significant and timely because its findings show that many common organic farming practices—like composting and the use of manure fertilization in place of synthetic fertilizers—can recycle reactive nitrogen that is already in the global system rather than introducing new reactive nitrogen into the environment, and thus have a much smaller environmental impact,” said Jessica Shade, PhD of The Organic Center. Earlier this year, researchers at the University of California Davis published a study in Science Advances with the finding that regulators in the state drastically underestimate chemical-intensive agriculture’s contribution to nitrogen oxide (NOx) caused air pollution, acid rain, and respiratory illness in the state. While NOx  pollution is usually associated with energy production and […]

(Beyond Pesticides, March 28, 2018)Â The Integrated Pest Management (IPM) in Healthcare Facilities Project, spearheaded by the Maryland Pesticide Education Network (MPEN) and Beyond Pesticides, are marking the Project’s 10th anniversary to reduce healthcare facilities’ pesticide use and impact, while maintaining a high level of pest management. Funded by Maryland-based foundations, the IPM in Healthcare Facilities Project services are pro bono. Maryland healthcare facilities strive to provide a high level of pest management to protect the compromised health of the at-risk people they serve, however often and unknowingly, many healthcare facilities respond to pest problems by having their contracted pest management vendors apply toxic pesticides as a first line of defense. These chemicals are often linked to the very issues for which patients are being treated. Pesticides can cause acute life-threatening reactions and linked to long-term impacts including cancer, asthma, Parkinson’s’ disease, developmental, reproductive and neurological impacts and immune dysfunction issues. The IPM staff, in collaboration with fourteen Maryland facilities, have worked diligently to reduce facilities’ pesticide use and impact, while maintaining a high level of pest management. Project staff educate facilities’ management and technicians about the dangers of patient pesticide exposure and the benefits of implementing an IPM program. An […]

(Beyond Pesticides, March 26, 2018) Tell your state AG to join the investigation of the merger of Bayer-Monsanto, the manufacturer of genetically engineered seeds tolerant of its herbicide glyphosate (aka Roundup®), and Bayer, the manufacturer of neonicotinoid insecticides responsible for pollinator declines, including imidacloprid and clothianidin. The giant seed and pesticide company that would be created by this merger would be a disaster for pollinators, people, and the environment. Farmers overwhelmingly think this mega-merger is a bad idea –a new survey and white paper were released that demonstrate widespread opposition of farmers to this merger. According to the poll, which was conducted by a coalition of farm organizations, 93 percent of farmers surveyed oppose it. More than one million Americans have called on the Department of Justice to stop it. Investigations are ongoing in both the EU and the U.S. Your state attorney general could play a key role in this fight by joining the investigation. Tell your state AG to join the investigation of the Bayer-Monsanto Merger! If this merger goes through, the new company would be the world’s largest vegetable seed company. It would control seeds for many of the crops we eat regularly — including broccoli, carrots, and onions. It would also be the largest manufacturer […]

(Beyond Pesticides, March 20, 2018) Regulations that separate ingredients in pesticide products as either “other/inert” or “active” have no scientific basis, according to a new review of the toxicity of formulated pesticide products published in the journal Frontiers in Public Health. Despite widespread awareness that “other” or “inert” pesticidal ingredients present toxicity concerns, only “active” ingredients undergo a full risk assessment, and pesticide products containing both active and inert ingredients are not tested in formulation before being sold to the public. Using glyphosate and neonicotinoid based products as examples, the study recommends sweeping changes to the way pesticide formulations are regulated in the Western world. Inert, or other ingredients –not disclosed on pesticide product labels, are often adjuvants that are added to a pesticide formulation to modify the effect of the active ingredient. However, they can also be sold separately and used in agriculture where pesticides are often “tank mixed” on site before application. Adjuvants take many forms, including surfactants, dyes, stabilizers, propellants, emulsifiers, solvents, antifoaming agents, and still other uses. Surfactants, likely the most common adjuvant, are added to a pesticide formulation in order slow the degradation time or improve the penetration of the active ingredient on a target […]

(Beyond Pesticides, March 19, 20018) Comment by April 4 to Protect Organic Integrity. Organic integrity is under unprecedented attack from the Trump Administration’s Department of Agriculture (USDA), Congress, and those who would like to sell food as “organic” without following the stringent rules established for organic food production and labeling. The National Organic Standards Board (NOSB), established to represent the organic community in advising USDA on organic practices, will be voting on important issues, and your input is critical to that process. The NOSB meets twice yearly to consider issues including materials used in organic production and oversight of the National Organic Program within USDA. Submit your comments at Regulations.gov! Enforcement is a critical component to any standard setting program. Recent reports in the Washington Post have highlighted fraudulent activities by companies selling products as organic. While this activity is certainly deviant, it taints the organic label and, if not dealt with seriously, will become a bigger problem. The NOSB will consider motions at the Spring 2018 meeting that will stop this practice. Your voice is needed to make this happen! Make your voice heard on this and other issues by submitting comments NOW on what materials and practices are allowed […]

(Beyond Pesticides, March 16, 2018) In a pattern of U.S. Department of Agriculture (USDA) actions that hurt the integrity of the organic label on food products, the agency has decided to withdraw final organic animal welfare regulations that would have provided standardized and measurable criteria for managing the health and welfare of organic livestock and poultry. USDA’s latest decision is another in a series of actions aimed at lowering the bar of organic integrity in order to serve the needs of large organic producers. In November of 2017, the National Organic Standards Board (NOSB), backed by the National Organic Program (NOP), rolled back decades of agreement that organic agriculture is soil-dependent, by allowing soil-less hydroponic operations to be certified organic. This has sparked stakeholders to collaborate on the development of an add-on label to certified organic food, with standards that meet the intent and letter of organic law. Despite widespread stakeholder disagreement and evidence to the contrary, USDA has concluded that the organic animal husbandry practice standards do not need to be improved  because existing regulations are “robust” and “effective,” despite widespread stakeholder disagreement. USDA justified withdrawing the regulations, by stating that they could “have a negative effect on participation […]

(Beyond Pesticides, March 14, 2018) The annual count of Monarch butterflies overwintering in Mexico shows declines from last year’s numbers—a 15 percent decrease –according to figures from an official Mexican government count in the winter of 2017. These numbers underscore how at risk the iconic animal is, with a possible collapse of migration if populations are critically low. Monarch butterflies (also known as Eastern Monarchs) embark on an impressive migration every year. Roughly 99 percent of all North American monarchs migrate each winter to oyamel fir forests on 12 mountaintops in central Mexico. Scientists estimate the population size by measuring the area of trees turned orange by the clustering butterflies. But for the second year in a row, its numbers are declining — 2.48 hectares of occupied winter habitat is down from 2.91 hectares last winter. Apart from partial rebounds in the winters of 2001 and 2003, numbers have gone down steadily since 1996. Overall monarchs have declined by more than 80 percent over the past two decades. Earlier this year, Western Monarchs – those found west of the Rocky Mountains – overwinter in coastal California forests, were also found to be declining at an alarming rate, with scientists and conservation groups […]

(Beyond Pesticides, March 12, 2018) European Regulators Confirm Neonicotinoids Harm Bees, Increasing Likelihood of Continent-Wide Ban A comprehensive assessment released last week by the European Food Safety Authority (EFSA) confirmed that neonicotinoids, the most widely used class of insecticides in the world, pose risks to honey bees and wild pollinators. EFSA analyzed over 1,500 studies from academia, beekeeper associations, chemical companies, farmer groups, non-governmental organizations, and national regulators. EFSA’s risk assessment provides a definitive, independent conclusion that overall, continued use of these chemicals risks the long-term health of pollinator populations. Tell Your Governor to Ban Neonicotinoid Insecticides “The availability of such a substantial amount of data as well as the guidance has enabled us to produce very detailed conclusions,” said Jose Tarazona, PhD, head of EFSA’s Pesticides Unit in a press release. This is EFSA’s second comprehensive evaluation of the three most commonly used neonicotinoids: imidacloprid, clothianidin, and thiamethoxam. Earlier research finalized in 2013 led the European Union (EU) to ban use of the three neonicotinoids on agricultural flowering crops. The new assessment applies EFSA guidance to assessing risks to bees and on the initial review. It includes literature not only on honey bees, but also on wild pollinators, including bumblebees […]

(Beyond Pesticides, March 9, 2018) Milk from 100% grass-fed cows has higher levels of beneficial fatty acids than conventional and even organic milk, according to a study published by an international team of scientists in the journal Food Science and Nutrition. The research follows up on data published in 2013, which compared only conventional and organic milk, finding organic milk contained 62 percent more omega-3 fatty acids and 25 percent fewer omega-6s. “Grassmilk farmers have long been telling us that they believed the nutrition of this milk was higher than that of the milk they were producing when they were still feeding grain,” said Logan Peterman, agricultural research and analytics manager at Organic Valley to Wisconsin Public Radio. “We kind of set about to test that question and really make sure that the signal was there, that we could be certain of it, that we were following the correct methods and also that it was sort of refereed by an outside party.” The study compared the composition of several fatty acids within the three types of milk tested (conventional, organic, and grass-fed). Of primary concern was the ratio of omega-6 to omega 3 fatty acids. Although omega-6s are not necessarily […]

(Beyond Pesticides, March 8, 2018) Simple approaches that increase populations of vertebrate predators, like bats and falcons on farms, can reduce pesticide use, increase on-farm productivity, and conserve wildlife, according to a literature review published by researchers at Michigan State University in the journal Agriculture, Ecosystems and Environment. Â The review encompasses 48 studies published over the last 150 years on the effect of human interventions to enhance natural ecosystem services. Results point not only to new methods to improve on-farm pest management, but also potential ways to engage farmers and citizen scientists in implementing these win-win strategies. Researchers looked at a number of methods tested in the scientific literature that would increase on-farm populations of vertebrate pest predators. Broadly, discrete approaches such as installing structures like nest boxes, perches, and artificial roosts were investigated alongside more wide-ranging systems aimed at altering habitat and increasing landscape complexity. The latter includes methods such as installing field borders, increasing tree cover, reintroducing native species, and eliminating invasives. The more discrete approaches provided a simpler, more accessible, and less expensive method of pest management when compared to approaches that require more wide-ranging landscape changes, though the benefits of those activities were not negligible. Nest […]

(Beyond Pesticides, March 2, 2018) Neonicotinoids, the most widely used class of insecticides in the world, do pose risks to honey bees and wild pollinators, according to a comprehensive assessment released last week by the European Food Safety Authority (EFSA). Encompassing an analysis of over 1,500 studies from academia, beekeeper associations, chemical companies, farmer groups, non-governmental organizations, and national regulators, EFSA’s risk assessment provides a definitive, independent conclusion that overall, continued use of these chemicals risks the long-term health of pollinator populations. After delaying a vote that would ban all outdoor uses of neonicotinoids in December in anticipation of EFSA’s assessment, the European Commission will revisit the issue as soon as March 22. “The availability of such a substantial amount of data as well as the guidance has enabled us to produce very detailed conclusions,” said Jose Tarazona, PhD, head of EFSA’s Pesticides Unit in a press release. This is EFSA’s second comprehensive evaluation of the three most commonly used neonicotinoids: imidacloprid, clothianidin, and thiamethoxam.

(Beyond Pesticides, March 6, 2018) Dover, New Hampshire is the latest community in the U.S. to restrict the use of toxic pesticides, and move towards organic land management on all public property. By a unanimous vote of the City Council last week, Dover passed a resolution that requires the management of city land with “sound land management practices, and the use of least toxic compounds only when necessary, . . . thereby eliminating exposure to toxic pesticides on the part of our citizens and the environment.” The ordinance also instructs the city manager to “develop and execute a plan to transition the City to eliminate the use of synthetic fertilizers on City property.” The resolution was spearheaded by Non Toxic Dover, a group of local advocates that engaged the city government on this issue for several years. “We are so grateful to the City of Dover NH for voting unanimously to take this important step to protect public health and our Great Bay estuary,” said Diana Carpinone, founder of Non Toxic Dover and lead advocate in the city for the new resolution. Ms. Carpinone said: “Thank you to the council and especially Councilor Shanhan for sponsoring the resolution. We look forward […]

(Beyond Pesticides, March 1, 2018)  A comprehensive review of notorious, bee-killing neonicotinoid insecticides finds that crop yields and on-farm profit can be maintained and improved by replacing these toxic chemicals with alternative pest management strategies. The new study is part of an ongoing update to the 2014 Worldwide Integrated Assessment undertaken by an international team of scientists called the Task Force on Systemic Pesticides. The results of this review point to the need for strong action against these chemicals by all levels of government. “Regulators need to realize that if we want sustainable agricultural practices, we need a more restrictive regulatory framework and programs to support farmers making the switch,” said Task Force co-chair and scientist at France’s National Scientific Research Centre Jean-Marc Bonmatin, PhD, in a press release. “Our findings on the availability of alternatives will be particularly relevant where new restrictions on neonics are being considered.” The Task Force reviewed 200 studies on systemic insecticides, looking at their use and pest resistance in annual and perennial crops, the viability of alternative pest management techniques, and the potential to implement alternative forms of crop insurance to cover risks, rather than spray expensive insecticides. For perennial crops, researchers focus on the […]

(Beyond Pesticides, February 26, 2018) It is no secret that large organic dairy herds of 15,000 to 20,000 cows or more dot the Western US in California, Colorado and Texas in particular. They have repeatedly come under fire from watchdog groups, journalists and farmers who have observed and documented the absence of cows on pasture during grazing season, as required by the Organic Foods Production Act (OFPA). This circumventing of the law could soon change with the commercialization of the fluorescene spectroscopy (FS), which detects the amount of forage a dairy herd is eating by measuring the luminescence of metabolized grass in milk. The law requires that herds graze daily during a given region’s growing season, at least 120 days per year, and consume a minimum of 30% grass in their daily diet. Until now, there has been no technology to scientifically verify that organic milk comes from grass-fed dairy cows. . The organic dairy certification system relies on visual inspections by certifiers during the grazing season and an evaluation of the dairy’s herd management plan.. While most organic dairies are in compliance, there are questions about the ability of the super-large dairies to meet stringent organic pasture regulations. The […]

(Beyond Pesticides, February 26, 2017) U.S. Representatives Earl Blumenauer (D-OR) and Jim McGovern (D-MA) reintroduced the Saving America’s Pollinators Act (H.R. 5015), which suspends the registration of certain neonicotinoid insecticides until the U.S. Environmental Protection Agency conducts a full scientific review that ensures these chemicals do not harm pollinators. Last week, Beyond Pesticides joined Rep. Blumenauer and other experts from environmental, conservation, whistleblower, and farmworker health groups on Capitol Hill to urge Congress to take action to protect pollinators in the face of ongoing obstruction by an increasingly industry-influenced EPA. Tell your Representative to cosponsor the Save America’s Pollinators Act!“ Pollinators are the backbone of America’s agriculture system. Acting now to protect them and stop their decline is essential to the sustainability of our nation’s food supply,” Rep. McGovern said. “Simply taking the word of the manufacturers that their products are safe is not an option. Consumers need strong oversight. That is why I am proud to join Congressman Blumenauer in demanding the EPA fully investigate the effect that certain harmful pesticides may have on the vitality of our pollinators.” Numerous scientific studies implicate neonicotinoid pesticides as key contributors to the global decline of pollinator populations. EPA’s own scientists have found that […]

(Beyond Pesticides, February 22, 2018) Online retailer Amazon will pay $1.2 million in penalties to settle violations to U.S. regulations for selling illegal and misbranded pesticides in its online store. Under the terms of the settlement, Amazon will monitor and remove illegal pesticide products from its website. These products, mostly imported, were not registered for use and sale in the U.S. and can pose hazards to unsuspecting consumers. As part of an agreement with the U.S. Environmental Protection Agency (EPA) Amazon has agreed to pay $1.2 million in administrative penalties for nearly 4,000 violations of the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA) by allowing third-party distributors to sell imported pesticide products on Amazon even though the products were not registered in the U.S. While agreeing to the settlement, Amazon neither admitted nor denied the specific facts alleged by the EPA. “This agreement will dramatically reduce the online sale of illegal pesticides, which pose serious threats to public health in communities across America,” EPA Region 10 Administrator Chris Hladick said in a news statement. The most concerning illegal products being sold are insecticide chalk products imported from Chinese manufacturers (3 pcs Cockroaches Bugs Ants Roach Kills chalk; Miraculous Insecticide Chalk; […]

(Beyond Pesticides, February 2, 2018) California regulators may be drastically underestimating chemical-intensive agriculture’s contribution to nitrogen oxide (NOx) caused air pollution, acid rain, and respiratory illness in the state, according to a new study published in Science Advances by researchers at University of California, Davis. While NOx  pollution is usually associated with energy production and vehicle emissions, fertilizer use on crop fields is contributing to significant air pollution problems. Advocates say that the study is an urgent call for farmers to eliminate dependency on soluble, synthetic, nitrogen-based fertilizers and adopt the use of insoluble soil amendments that support soil biology that provide plants with nutrients. NOx gasses are major sources of pollution in the U.S. and throughout the world, and include the compounds nitrogen oxide (NO) and nitrogen dioxide (NO2). Chemical-intensive, synthetic nitrogen fertilizers are applied in a form that is readily available to plants, while organic nitrogen fertilizers require the biological life in the soil to break down the fertilizer into a form that plants can use. These nitrogen fertilizers that are not immediately taken up by plants can cause pollution problems. Natural nitrogen in the atmosphere must be transformed to be able to be used by organisms as […]

(Beyond Pesticides, January 24, 2018) Poor nutrition coupled with exposure to a notorious class of insecticides known as neonicotinoids act synergistically to significantly reduce the survival of honey bees and their colonies, according to research published by scientists from University of California, San Diego (UCSD). This is the first study to delve into the real-world effects pesticide exposure can have on honey bees also subject to nutritional stress, a common occurrence in the wild. The outcome of this research highlights the weaknesses of the U.S. Environmental Protection Agency’s (EPA) testing regime for registering pesticides, which does not account for the complex ecology surrounding catastrophic declines in honey bee and other wild pollinator populations. UCSD scientists looked at two of the most popular neonicotinoids, chlothianidin and thiamethoxam, to investigate how realistic levels of exposure to the chemicals interacted with varying levels of available food. High and low levels of both chemicals, 1/5 and 1/25 of the LD50 (amount at which 50% of honey bees exposed would die) were added to sugar syrup solution containing a range of different nutrition levels. Sugar syrup, which mimics nectar and honey, is a critical source of carbohydrates for honey bees. The bees studied were either […]

(Beyond Pesticides, January 18, 2018) Research published in early January 2018 has shown that — despite a partial ban on neonicotinoid insecticides instituted in 2014 — 25% of British honey is still contaminated with residue of these “potent, bee-killing” pesticides. The partial ban, which extended to flowering crops, such as oilseed rape (from which canola oil is made), was instituted by the European Union (EU) in response to evidence of serious threats to bee populations. Samples for this study came from beekeepers and were each from a single location. After the partial ban went into effect, scientists had seen some reduction in the contamination rate of neonicotinoids in honey, from greater than 50% prior to the ban. This study demonstrates that these powerful pesticides nevertheless remain common in agricultural areas, posing serious threats to bees (and other pollinators). This discovery is likely to accelerate pressure on the EU to ban all outdoor use of neonicotinoids, with a vote coming perhaps as soon as in the next few months. “While the frequency of neonicotinoid contaminated samples fell once the EU ban was in place, our data suggest that these pesticides remain prevalent in the farming environment,” said Ben Woodcock, of the UK’s […]

(Beyond Pesticides, January 12, 2018) Honey bees display a concerning attraction to the herbicide glyphosate and the fungicide chlorothalonil at certain concentrations, new research from scientists at the University of Illinois (UIL) reveals. Results are reminiscent of a 2015 study published in the journal Nature, which found that honey bees display a preference for foods treated with neonicotinoids, a class of insecticides implicated in global pollinator declines. Since the crisis became public knowledge in 2006, managed honey bees have experienced unsustainable levels of colony loss, and one in four species of native bees in North America and Hawaii are at risk of extinction. This new research adds to growing concerns that, while neonicotinoids continue to play a primary role in the pollinator crisis, their elimination would still leave a myriad of other toxic chemical threats to the recovery of these critical species, upon which so much of our food supply relies. UIL scientists investigated honey bees’ preference for a range of pesticides as well as a number of naturally occurring chemicals that honey bees would likely encounter in the field. In the experiment, pollinators were put in a large enclosure and allowed to fly to different feeders stocked with either […]
