(Beyond Pesticides, April 13, 2018) Hawaii is poised to become the first state in the nation to prohibit the use of pesticides containing the developmental neurotoxicant, chlorpyrifos. SB3095, passed unanimously by the State House of Representatives this week, prohibits the application of restricted use pesticides (RUPs) within 100 feet of schools when they are in session, and it requires commercial agricultural entities to regularly report their RUP use to the Department of Agriculture (DOA). In the absence of adequate federal procedures to protect communities from hazardous pesticide drift, this bill represents the culmination of efforts by the people of Hawaii to ban and restrict the most egregious pesticides and to increase the transparency regarding their use. As bill supporters rallied in the Capitolâs Rotunda this week, SB3095 was sent to the Senate. No date has yet been set for its consideration, but Senators who support the bill hope to secure the 13 votes needed to pass it and avoid further weakening of its provisions. Beyond Pesticides has actively supported this and previous iterations of SB3095, arguing for the establishment of a much more protective one mile buffer zone between schools and RUP applications to safeguard school children where they learn.

(Beyond Pesticides, April 12, 2018) The Justice Department will allow two notorious agrichemical corporations, Bayer and Monsanto, to merge, according to reports published earlier this week. Despite strong voices of opposition from grassroots advocates across the country, and investigations by state Attorneys General, the over $60 billion merger was approved after Bayer agreed to sell off select sectors to another competitor, BASF. Â The merger will make Bayer the largest seed and pesticide company in the world. While lining the pockets of C-suite executives, farmers will be hurt by decreased competition and greater costs, which will ultimately affect consumer prices for food. China, Brazil, Australia, and the European Union (EU) signed off on the deal prior to U.S. approval. As part of EU negotiations, Bayer agreed to divest $7 billion, selling off its soybean and cottonseed sectors, as well as its glufosinate herbicide division, which competes with Monsantoâs Roundup. Bayer also promised European regulators that it would not attempt to foist genetically engineered (GE) crops onto European consumers. Â The U.S. Justice Department added additional requirements, noting that widespread use of GE crops in America meant there would be different considerations. According to reports, Bayer will need to sell off additional seed […]

(Beyond Pesticides, April 11, 2018) The request by shellfish growers in Washington State to apply the neonicotinoid insecticide, imidacloprid, on oyster and clams beds to control native burrowing shrimp was denied by the Department of Ecology (Ecology) after it determined âenvironmental harm from this neonicotinoid pesticide would be too great.â Concerned resident and environmental advocates have been opposed to the proposed use citing harms to aquatic life including fish habitat, and long-term ecological damage. Shellfish growers from Willapa-Grays Harbor Oyster Growers Association requested a permit from the state to use the imidacloprid on burrowing shrimp that the growers said impede traditional shellfish cultivation. They sought a state National Pollution Discharge Elimination System (NPDES) permit to apply imidacloprid to 500 acres of shellfish beds within Willapa Bay and Grays Harbor, over a period of five years. The growers first applied for a permit in 2015 to treat 2,000 acres of tidelands, but after a strong public outcry, they withdrew the request. In 2016, they applied for a new permit to treat less acreage and Ecology published a draft Supplemental Environmental Impact Statement (SEIS) in 2017 on the potential impacts imidacloprid application would have to the bay. Now, Ecology, after thoroughly evaluating […]

(Beyond Pesticides, April 10, 2018) Current strategies aimed at managing herbicide resistant weeds in agriculture are not effective and may exacerbate weed problems, according to research published earlier this year by scientists at University of Sheffield in the United Kingdom (UK). While the conventional wisdom in farming, promoted strongly by the chemical industry, is that resistance can be adequately managed by rotating the herbicides used, researchers did not find evidence to support this strategy. In an ode to Occamâs razor, a philosophical theory that hypotheses with the fewest assumptions may be the correct one, researchers found the best method to reduce weed resistance to herbicides was to reduce the overall use of herbicides. Sheffield scientists focused their research on the occurrence of a common weed in the UK called black-grass. This weed was found to occur on 88% of the farmland tested in the study, and has recently been spreading into new areas it had never before colonized. Rob Freckleton, PhD, a population biologist and co-author of the study indicated to Science Daily, “The driver for this spread is evolved herbicide resistance: we found that weeds in fields with higher densities are more resistant to herbicides.â Thus, the more abundant […]

(Beyond Pesticides, April 9, 2018)Â A new international study finds that the unsustainable exploitation of natural resources worldwide has reached critical proportions, causing biodiversity loss and land degradation that threaten the food and water security of an estimated 3.2 billion people. Congress must act for the U.S. to become a signatory to the United Nations Convention on Biodiversity, joining the global community in working to develop and implement solutions to the biodiversity crisis. Urge your U.S. Representatives and Senators to call for a vote in Congress to support the U.S. becoming a signatory to the UN Convention on Biodiversity. The Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) report unearths the crisis faced by two-fifths of the worldâs population due to the worsening of land degradation, declining species biodiversity, and the intensification of climate change. Though the report presents a bleak picture of how humans have substantially degraded the natural resources essential to survival, it holds up indigenous knowledge and land-use practices as potential models for how to use natural resources for human benefit, while still protecting biodiversity. However, the cultures that possess this knowledge are also in jeopardy. More than 60 percent of indigenous languages and cultures in the […]

(Beyond Pesticides, April 6, 2018) Scott Pruitt, Administrator of the U.S. Environmental Protection Agency (EPA), is getting plenty of attention for what the public and some members of Congress see as his spendthrift and potentially corrupt behaviors since taking office in early 2017. Pundits and prognosticators who focus on the Washington, DC scene are speculating that this attention is not welcome by the White House, and wonder if Mr. Pruitt will soon be on the âwrong end of a Trump tweet.â This may be refreshing news to environmental advocates, scientists, and public health experts, who have objected to the âchangesâ heâs brought to the agency, which frequently favor industry interests over science-based protection of the environment and public health. EPAâs moves to reduce enforcement, roll back protective regulations, and install industry-friendly personnel have been covered extensively by Beyond Pesticides; examples include: âWhere Has All the EPA Enforcement Gone,â âThe Threat to Scientific Integrity at EPA,â and regular posts in its Daily News Blog. Administrator Pruitt calls his approach to EPAâs function âBack to Basics,â which he says includes a refocus on EPAâs âintended mission, a return of power to the states, and creation of an environment where jobs can grow.â The […]

(Beyond Pesticides, April 5, 2018) An industry-backed attempt to enact pesticide preemption in the state of Maine is officially over after bill LD 1853 was voted down by a 9-2 margin earlier this week. The bill, introduced by state Senator Tom Saviello (R-Wilton), resembled a similar bill that failed in the same legislative committee last spring. With an ever increasing number of communities in Maine stepping up to protect their residents and unique local environment from pesticide contamination, the repeated introduction of preemption legislation means that health advocates and forward-thinking communities must continue to remain vigilant, and ready to fight to maintain their right to home rule. LD 1853 would have taken away the rights of Maine municipalities to enact policies which wholly apply to private property. âI thought if there was a bill that would come back before us again it would be different,â said state Representative Richard Pickett (R-Dixfield) to the Portland Press Herald. âBut we virtually had almost a duplicate bill and that troubled me.â While last yearâs failed legislation was modeled almost word for word from the notorious industry lobby group the American Legislative Exchange Council (ALEC), the changes in the new bill were superficial, and […]

(Beyond Pesticides, April 4, 2018) In late March, the Missouri Department of Agriculture hosted a public hearing to discuss a proposed emergency rule restricting the sale and use of the herbicides dicamba and 2,4-D â which are known for their ability to drift off-site and damage sensitive crops. The emergency rule was introduced to prevent off-label use of specific dicamba or 2,4-D products. Thus far, dicamba is responsible for damaging approximately 325,000 acres of soybeans in the state last year. The proposed rule will stop sales of the herbicides dicamba and 2,4-D between April 15 and October 1 in Missouri. The departmentâs goal is to prevent off-label pesticides from drifting onto neighboring property and damaging other crops. According to the department, if it chooses to pursue an emergency rule, it could become effective as soon as April 1, 2018, and expire 180 days later. The rule also requires registrants to provide a sales record by April 30 for each pesticide sold between October 1 and April 15. A proposed rule will be filed at the same time as an emergency rule to initiate the formal rulemaking process. The draft rule language reads as follows: Pesticides that meet the conditions of this section are […]

(Beyond Pesticides, April 3, 2018)Â Humans’ unsustainable exploitation of natural resources, worldwide, has reached critical proportions, threatening the ability of an estimated 3.2 billion people to have food and water security, according to a new international study. The Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services report (IPBES) unearths the crisis faced by two-fifths of the worldâs population due to the worsening of land degradation, declining species biodiversity, and the intensification of climate change. While the report presents a bleak picture of how humans have substantially degraded the natural resources essential to survival, it also offers some hope by identifying the changes could be adopted by governments with a political will. Publication of the IPBES comes with a stern warning from the reportâs Chair, Robert Watson, PhD, who cautions that âthe time for action was yesterday or the day before.â The extensively peer-reviewed report, conducted by 100 experts from 45 countries, represents a compilation of four regional assessments in the Americas, Asia and the Pacific, Africa, and Europe and Central Asia. It is intended to provide policy makers with âthe best available evidenceâ to make important decisions about corrective actions they can take to avoid, reduce, and even reverse land degradation […]

(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 âreactive nitrogen,â 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. âThis research is significant and timely because its findings show that many common organic farming practicesâlike composting and the use of manure fertilization in place of synthetic fertilizersâcan 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,â 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 29, 2018) Rising use of antibacterials like nanosilver in textiles and other consumer goods is leading scientists to consider methods to filter out these materials before they pollute the environment. As detailed by research published in Sustainable Chemistry and Engineering, experts at University of Massachusetts, Dartmouth, are developing a process to filter out these toxic materials from our washing machines. While preventing downstream waste is laudable, it misses the fundamental question whether nanosilver and other antibacterials need to be added to consumer clothing in the first place. Nanosilver is antimicrobial nanoparticle (typically defined as a particle between 1-100 nanometers) regulated as a pesticide that is added to consumer goods such as textiles, cosmetics, disinfectants, toys and other household items in attempts to kill bacteria or reduce odor. See the Project on Emerging Nanotechnologies for an extensive listing of products containing nanoparticles on the market. Nanosilver, which makes up roughly 25% of nanomaterials used in the consumer market, is a particularly concerning nanoparticle given past research on its risks to health and the environment. Studies have found that, when impregnated into textiles like sportswear, nanosilver does not just wash out in the washing machine, it can also seep […]

(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 27, 2018) In a major win for farmworker and health groups, the U.S. District Court for the Northern District of California ruled last Wednesday the U.S. Environmental Protection Agency (EPA) illegally delayed implementation of key pesticide rules that in part prevent minors from working with the most dangerous pesticides. The rule revised rules mandate pesticide applicators be at least 18 years old. According to the EPA, there are about one million certified applicators nationwide. Before delaying implementation, the agency said the revised rule could prevent some 1,000 acute poisonings every year. In addition to requiring applicators to be at least 18-years-old, the revised 2017 Certification of Pesticide Applicators (CPA) rule also improves the quality of training materials and says certified pesticide applicators must be able to read and understand the instructions. The main purpose of the CPA rule is to protect workers and the public from poisonings, by ensuring that those who handle the most dangerous pesticides are properly trained and certified. “We commend the court for recognizing that this important pesticide safeguard is needed to prevent injury to farmworkers and the public,â said Stacey Geis, Earthjustice managing attorney. âThis ruling puts EPA Administrator Scott Pruitt on notice that the courts […]

(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 RoundupÂŽ), 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 âa 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 worldâs largest vegetable seed company. It would control seeds for many of the crops we eat regularly â including broccoli, carrots, and onions. It would also be the largest manufacturer […]

(Beyond Pesticides, March 23, 2018) French scientists and ornithologists say parts of the countryâs forests, streams, and bucolic landscapes could be completely devoid of birdsong this year, as the results of two recent studies show staggering declines in bird populations throughout the nation linked to the intensification of agricultural practices and pesticide use. The advent of so many significant wildlife declines at the same time ânow recognized in birds, but also seen in pollinators and insect populationsâis leading many to wonder whether the modern world has forgotten the warnings of Rachael Carson’s Silent Spring back in 1962. âWeâve lost a quarter of skylarks in 15 years. Itâs huge, itâs really, really huge. If this was the human population, it would be a major thing,â said Benoit Fontaine, PhD, of Franceâs National Museum of Natural History and co-author of one of the new studies to The Guardian. âWe are turning our farmland into a desert. We are losing everything and we need that nature, that biodiversity â the agriculture needs pollinators and the soil fauna. Without that, ultimately, we will die.â The French National Museum of Natural History and the National Centre for Scientific Research each conducted an investigation into countryâs bird […]

(Beyond Pesticides, March 22, 2018) Last week Environmental Protection Agency (EPA) Administrator Scott Pruitt received a letter from twenty-eight U.S. Senators urging the preservation of rules that would protect farmworkers and disallow minors to handle highly toxic pesticides. At issue are two proposals from Administrator Scott Pruittâs EPA that would roll back Agricultural Worker Protection Standards (AWPS) and the Certification of Pesticide Applicators (CPA) rules put in place during the Obama Administration. In their letter, the Senators stress the impact of any potential changes, noting âthe lives of children and families across the country at stake.â During the Obama era, EPA completed rulemaking that revised AWPS for the first time in over 20 years. Key components expanded training, prohibited children under 18 from applying highly toxic restricted use pesticides, created new no-entry application-exclusion zones, improved record keeping, provided farmworkers a designated representative to request pesticide records, and other safety improvements. The final rules put in place long-overdue protections, but still represented a compromise for workers and farmworker advocates. At the time the rules were released, advocacy organization Farmworker Justice released a statement noting, âWhile we are disappointed that the final rule does not include some significant safety measures, we will […]

(Beyond Pesticides, March 21, 2018) According to a new study published this month in Environment Health, women with high levels of glyphosate in their bodies are more likely to have shorter pregnancies. Shorter pregnancies can lead to children with reduced learning and brain development. This is the first study to suggest that exposures to glyphosate can influence the long-term well-being of children. The study, Glyphosate exposure in pregnancy and shortened gestational length: a prospective Indiana birth cohort study, obtained both urine and drinking water samples from 71 women with pregnancies living in Central Indiana while they received routine prenatal care, and analysed the relationships of glyphosate levels in motherâs urine with fetal growth indicators and gestational length. The researchers found that more than 90 percent of pregnant women had detectable levels of glyphosate where higher glyphosate levels were significantly correlated with shortened gestational lengths, even though the drinking water samples had little to no detectable levels of glyphosate. Women living in rural areas were found to have higher glyphosate levels. The authors note their study is significant because it is the first U.S. study designed specifically to measure prenatal glyphosate exposure in pregnant women to determine its association with adverse fetal […]

(Beyond Pesticides, March 20, 2018) Regulations that separate ingredients in pesticide products as either âother/inertâ or âactiveâ 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 âotherâ or âinertâ pesticidal ingredients present toxicity concerns, only âactiveâ 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 ânot 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 âtank mixedâ 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)Â Comment by April 4 to Protect Organic Integrity. Organic integrity is under unprecedented attack from the Trump Administrationâs Department of Agriculture (USDA), Congress, and those who would like to sell food as âorganicâ 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. USDAâs 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 ârobustâ and âeffective,â despite widespread stakeholder disagreement. USDA justified withdrawing the regulations, by stating that they could âhave a negative effect on participation […]

(Beyond Pesticides, March 15, 2018) On Tuesday, a group of 56 scientists studying the effects of neonicotinoids sent a letter to Californiaâs Department of Pesticide Regulation (CDPR) highlighting the threat neonicotinoids pose to the health of Californiaâs waterways. The scientists urge CDPR to take steps to reduce neonicotinoid contamination of the stateâs streams and rivers. This comes as neonicotinoids were recently reported to be pervasive throughout the Great Lakes, and federal assessments confirm high risks to aquatic species. According to the letter, neonicotinoids are already found in California waterways at levels that exceed the freshwater invertebrate aquatic life benchmarks and could harm or kill many sensitive aquatic invertebrate species. Citing a 2016 study by the Xerces Society that found imidacloprid frequently in Californiaâs rivers and streams at levels harmful to species such as mayflies and caddisflies. Imidacloprid samples in California from 2010-2015 showed that 42% (197 of 468) of detections exceeded the acute invertebrate benchmark and all of the detections exceeded the chronic invertebrate benchmark. In certain regions of the state, particularly agricultural areas, the imidacloprid benchmark for acute effects was more frequently exceeded. The scientists note these chemicals can âhave consequences for broader ecosystems. Declines in aquatic invertebrates put other species […]

(Beyond Pesticides, March 14, 2018) The annual count of Monarch butterflies overwintering in Mexico shows declines from last yearâs numbersâa 15 percent decrease âaccording 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 â 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 â those found west of the Rocky Mountains â overwinter in coastal California forests, were also found to be declining at an alarming rate, with scientists and conservation groups […]
