Aminopyralid: We Need  to Stop This (No Dig Home blog, 13 June 2019)

After reading this blog post, I did some research on aminopyralid. 

The most concise and objective article I found was ChemicalWatch Factsheet Aminopyralid (Beyond Pesticides)  which recounts several incidents of manure and hay contamination which led to crop losses. 

The PANNA pesticide data base shows mostly ? for major effects, likely because the chemical has has been registered reasonably recently (2005 in the US, 2006-12 in Canada)   and there have been no independent reviews. Also note that the US registration was conditional which means that all the mandatory tests were not performed. 

PMRA label search indicates 11 current Canadian labels. (22 August 2019). The product names include MilestoneRestoreClearview and Reclaim.

The National Library of Medicine HSDB Database (TOXNET) also has a page on Aminopyralid  'Occupational exposure to aminopyralid may occur through inhalation and dermal contact with this compound at workplaces where aminopyralid is produced or used.'

I found very few scientific articles on google but this one was interesting:

Aminopyralid soil residues affect rotational vegetable crops in Florida 16 March 2011 (wileyonlinelibrary.com) DOI 10.1002/ps.2119 Spraying with aminopyralid of the bahiagrass used in rotation caused severe damage to following crops.

Clopyralid is apparently not registered in Canada at this time.

Chlorpyrifos (PAN fact sheet)  very good. no date of publication but references up to 2017.

Brain Function Damage from Exposure to Organophosphate Pesticides, including Chlorpyrifos, Documented with Imaging  (Beyond Pesticides, August 30, 2019)  'The subject adolescents — estimated to have relatively high levels of prenatal exposure to organophosphates — showed aberrant brain activity in executive function, attention, social cognition, and language comprehension, compared to their peers.'   'Associate adjunct professor of epidemiology at UC Berkeley and lead author of the new study, Sharon Sagiv, PhD, said, “These results are compelling, because they support what we have seen with our neuropsychological testing, which is that organophosphates impact the brain.”'

European Regulators Issue Warning on Danger of Chlorpyrifos Prior to Release of Full Review   (Beyond Pesticides, August 22, 2019) 'In early August, experts from European Union (EU) member states and staff members of the European Food Safety Authority (EFSA) announced their conclusion that chlorpyrifos fails to meet criteria for renewed approval for use, potentially moving the EU a step closer to an outright ban.'  'The EU and EFSA experts included in their findings:

  1. a genotoxic potential for chlorpyrifos cannot be ruled out
  2. chlorpyrifos meets the criteria for classification as toxic for reproduction (REPRO 1B, H360D, “May damage the unborn child”), as set out in EU regulation (EC) No 1272/2008)   SNAP Comment: There are still 28 chlorpyrifos products registered in Canada as of 22 August 2019.

Evaluation Used to Support Registration of Neurotoxic Chlorpyrifos Found To Be Fundamentally Flawed (Beyond Pesticides, November 20, 2018)  Scientific conclusions used to support the registration of the insecticide chlorpyrifos were flawed and omitted key health impacts, according to a fresh analysis of the original data by a team of independent scientists from northern Europe and the U.S. This re-review not only casts further doubt on the safety of the neurotoxic chlorpyrifos, it highlights a major flaw within federal pesticide regulation that allows pesticide producers to submit their own safety evaluations to the U.S. Environmental Protection Agency without public oversight. “One conclusion we draw is that there is a risk that the results of industry-funded toxicity tests are not reported correctly,” says co-author Axel Mie, PhD. “This makes it difficult for the authorities to evaluate the pesticides in a safe and valid way... While these studies are generally considered ‘confidential business information’ and not available to the public, using Swedish freedom of information laws, researchers were able to obtain two key studies relating to the developmental neurotoxicity of chlorpyrifos

Brain and Behavioral Effects of Early Exposures to Neurotoxicants  (University of California Television (UCTV), Aug 11, 2015)  There is also a significant link to meaningful tremors and learning deficits. This presentation addresses the impact of prenatal exposure to a common neurotoxicant on brain structure and neuropsychological function in an inner-city cohort of minority children. The toxic chemical, an organophosphate insecticide (chlorpyrifos), has been banned for indoor residential use in the U.S. since 2001, but continues to have widespread application for agricultural purposes. Possible moncholinergic mechanisms involve disruption of neural cell development and neurotransmitter systems, including the formation and activity of synapses in different brain regions. This presentation examines the evidence for long-term effects of prenatal chlorpyrifos exposure on neuropsychological profiles and brain morphology as measured by MRI. Series: "MIND Institute Lecture Series on Neurodevelopmental Disorders" Health and Medicine Professional Medical Education Show ID: 29838

California to List Chlorpyrifos as a Toxic Air Contaminant (Beyond Pesticides, August 8, 2018) "based on evidence of its neurological effects and exposure risks of concern...According to the assessment, “chlorpyrifos meets the criteria of TAC designation based on either the developmental neurotoxicity endpoint or the AChE inhibition endpoint, even without the additional 10x uncertainty factor necessary to account for the fact that the developmental neurotoxicity effects occur at a lower level than AChE inhibition.” As defined in California, a TAC is “an air pollutant which may cause or contribute to an increase in mortality or an increase in serious illness, or which may pose a present or potential hazard to human health.”"

Poison Fruit    Dow Chemical Wants Farmers to Keep Using a Pesticide Linked to Autism and ADHD (The Intercept, 14 January 2017) A fascinating article reviewing the history of the organophosphate chlorpyrifos regulation in the United States. Reviews the research directly linking it to autism and several other disorders, the need for suing the US EPA to get action and Dow's constant efforts to keep chlorpyrifos on the market including bad studies, threats to sue the EPA, and success in changing the law. Long and lots of links." While the US nationwide autism rate is now one in 68, for women who lived near fields where chlorpyrifos was sprayed during their second trimester, the chance of having a child with autism was closer to one in 21." Effects on children's brains occur at levels 20 times below the EPA’s safety level. In spite of the evidence linking autism to environmental causes, the National Institute of Health (NIH) is only funding studies on environmental causes at 1/20th of the genetic ones. Dow's latest efforts: "Instead, the chemical industry has renewed its efforts to derail the proposed regulation. On November 29, (2016)  CropLife America launched a Hail Mary effort to stop the ban. The business group petitioned the head of the office of pesticide programs to “cease regulatory decision making” on chlorpyrifos until it has developed standards “for acceptance of epidemiologic studies in human health risk assessment,”" a process that could easily take several years.". However, there are still several potential ways it (Dow) could circumvent the regulation without technically defying the law.

SNAP comment: Here we have it from the mouth of industry: there is currently no process “for acceptance of epidemiologic studies in human health risk assessment.That is why it is so easy for regulatory agencies to ignore or set aside epidemiological studies in their pesticide re-evaluations, especially when the committees consist of several 'regulatory' scientists or others deriving their income from the pesticide industry. I don' t believe there is much of a mechanism or standard for regulatory agencies to evaluate anything but the studies mandated for registration. As of 16 January 2017, there are still 29 chlorpyrifos products registered for use in Canada.

Dicamba Herbicide Poses Greater Threat of Drift when Mixed with Glyphosate  (Beyond Pesticides, July 18, 2019) 'During a 60-hour window, scientists applied various GE dicamba products (Clarity and XtendiMax) over a range of temperatures and took air samples. As temperatures increased, so did the volatilization and drift of dicamba, even in formulations touted as “low volatility.”'  'Adding glyphosate to the mixture produced stark results, increasing concentrations of dicamba in the air up to nine times compared to dicamba alone... and research finds that even trace amounts of dicamba in the air, levels in the parts per million, can damage non-resistant crops.'   SNAP Comment: This research illustrates another failures of the US and Canadian regulatory system. This interaction was totally missed by only requiring testing these pesticides separately even though they are used in formulation.

Arkansas Tried to Restrict the Use of This Controversial Pesticide. Monsanto Fought Back and Won. Dicamba drift has damaged millions of dollars worth of crops, as well as wildflowers that honeybees rely on to produce honey. (LIZA GROSS, Mother Jones, MARCH 1, 2019)   'As reported last year by FERN and Reveal, dicamba has damaged millions of dollars worth of crops over the past two years, after the EPA dismissed scientists’ concerns and approved the weedkiller for new uses on soybean and cotton seeds that Monsanto engineered to tolerate it. It has also harmed trees, gardens, and the wildflowers bees need to thrive and produce honey. '

Beyond Damaging Crops, Dicamba is Dividing Communities (Civil Eats, BY VIRGINIA GEWIN, Nov 8 2018)  As the EPA extends use of the controversial herbicide for two more years, farmers continue to take sides, and the effects on rural America are snowballing.'As dicamba use increases, so does the likelihood of non-farmers reporting damage. The number of homeowners and individuals reporting damage to gardens, trees, shrubs, and lawns, definitely increased in 2018 compared to 2017, says Norsworthy. “As individuals become more educated about the symptoms, they are more likely to pick up the phone and report it,” he adds.'   SNAP Comment: Indeed. It is a concern that states are no longer reporting or even collecting incident occurrences. This does not serve the public, the farming community, and only increases the doubts cast on the regulatory environment.

Widely Used Fungicide Found to Adversely Affect Enzyme Common to All Cells   (Beyond Pesticides, July 5, 2019) 'This is a story about a chemical pesticide, a fungicide, in wide use for which the mode of action, i.e., the ability to cause harm, has not been fully understood. It is not a story unique to this pesticide... The ability of the fungicide fludioxonil to act on a sugar-metabolizing enzyme common to all cells, and to produce the damaging compound methylglyoxal, may mean that the pesticide has more potential to harm non-fungal cells than previously thought.'   'Fludioxonil, a phenylpyrrole fungicide, which was developed to treat seeds during storage. However, it has come to be used commonly on grains, vegetables, fruits, and ornamental plants during cultivation, and worse (more on this below), to treat produce after it has been harvested to extend “shelf life.” Though fludioxonil is effective in killing fungi, the mode, or mechanism, of action for this pesticide was previously not well understood. 'Dr. Brandhorst notes, “The take home lesson is that fludioxonil is multifactorial. It’s not compromising cells by one solitary mechanism. It has potential to damage cells in a variety of ways.”'

  • Fludioxonil persists in soil — near the surface for weeks, and for years if it ends up deeper in the soil, 
  • it is also a “super toxin” for earthworms.
  • The fungicide’s extensive post-harvest use on food crops is of particular concern because it eliminates break down mechanisms 
  • the waxy fungicide is not easily removed by rinsing.
  • Further, UV-vis treatment of produce (which is sometimes done to reduce pathogens on fresh fruits and vegetables) actually significantly increases the toxicity of fludioxonil.
  •  is an EPA Category I toxin — “highly toxic and severely irritating” — to aquatic plants, bacteria, insects, fish, and aquatic invertebrates
  • “there is also reason to believe that breakdown products of this pesticide may be 100 times more toxic than fludioxonil itself.”
  • Synergistic potential. 'A 2012 study by French researchers found that a mixture of fludioxonil and cyprodinil, another fungicide, yielded data suggesting cytotoxic (lethal to cells) and genotoxic (damaging to DNA)' 

Neither the US EPA or the PMRA comprehensively evaluates pesticides for synergistic effects. 'In 2016, the Center for Biological Diversity wrote an extensive report on this issue: Toxic Concoctions: How the EPA Ignores the Dangers of Pesticide Cocktails.' 

SNAP Comment: There are currently 39 fludioxonil products registered in Canada as of 20 July 2019. Several are in combination with other pesticides. In addition ot seed and potato seed treatment, some formulations are used on leafy vegetables like spinach, fruit and vine climbing crops and turf in golf courses. I did not do an exhaustive search of all labels. This looks like an emerging problem, perhaps the next glyphosate?

Despite Safety Claims, Insecticide Flupyradifurone Is Bee-Toxic on Its Own and Worse in Combination  (Beyond Pesticides, April 17, 2019)   'It functions in the same way as a neonicotinoid, though it is in the butanolide family.' 'It also delves into the FPF’s synergistic effects with a commonly used fungicide propiconazole (PRO).'. Link to study in article..  SNAP Comment: As of 20 April 2019, this insecicide does not appear to be registered in Canada

'EPA Considers 300,000-Acre Expansion of Bee-Toxic Pesticide  (Beyond Pesticides, October 19, 2018) Pollinator advocates and the Center for Biological Diversity (CBD) are imploring the U.S. Environmental Protection Agency (EPA) to deny Bayer CropScience’s application for use of “Sivanto,”a pesticide product with the active ingredient flupyradifurone, a chemical the company claims is safer for bees, but poses the same risks at the notorious bee-toxic neonicotinoid insecticides. If approved, Sivanto would be sprayed in tobacco-growing states along 300,000 acres in the southeast U.S., areas home to more than three dozen species protected under the Endangered Species Act (ESA)Bayer’s proposal for expanded uses comes after EPA’s own assessment indicated risks to endangered species, and despite the fact that the agency has not undergone an ESA mandated consultation with federal wildlife agencies. Flupyradifurone is a systemic insecticide like neonicotinoids, and is highly water soluble.

SNAP Comment: According to PANNA Pesticide Database, it is of 'unclassified' chemical class. Five flupyradifurone have first been registered in Canada since 25 November 2015. It is therefore a recent product, too 'young' to have been submitted to independent research but seemingly, company data indicates 'risks to endangered species.'  Here is what the Sivanto label says:

'Section 2: The Product
Sivanto Prime Insecticide is intended for the control of insect pests in a wide variety of
vegetable crops, fruit crops and field crops. Sivanto Prime Insecticide is a broadspectrum
insecticide that is acropetally systemic, moving from roots to the leaves in the
case of soil applications. Sivanto Prime Insecticide moves translaminarly through the
leaf tissue in the case of foliar applications, and can provide control of pests on the
underside of leaves. Sivanto Prime Insecticide is readily absorbed into leaf tissue and is
considered “rainfast” within 1 hour after spray dries. Sivanto Prime Insecticide can be
applied by air-blast, aerial and ground application equipment.'

Glyphosate testing

Glyphosate decreases mycorrhizal colonization and affects plant-soil feedback (Marjo Helander et al, Science of The Total Environment,Volume 642, 15 November 2018, Pages 285-291)  Highlights

  • In northern ecosystems glyphosate residues are detected in crop plants the following growing season.
  •  Arbuscular mycorrhizal colonization is decreased in glyphosate treated plants.
  • The magnitude of mycorrhizal reduction is dependent on tilling and soil history.

The Pesticide Generation   Children on the Front Line  (Webdoc.France24.com,original FRANCE 24 multimedia documentary has been translated from the original in French, 2019)  A court case against glyphosate and what is happening in France about banning glyphosate. "The medical community is unambiguous: Théo’s malformations are not genetic, but definitely linked to an external factor. “Right from birth, Théo’s doctors pointed a finger at pesticides,” says Sabine, who at the time didn’t make an immediate connection to the weed killer that she used at home to spray the horse paddock. “The wake-up call came later,” she remembers. In August 2008, to be precise. Just as she did every year at the same time, Sabine treated the area with Glyper, a herbicide containing glyphosate. “It suddenly hit me; I remembered what the surgeon had told me about pesticides.” Due to the teratogenic risks of glyphosate causing malformation of embryos and foetal abnormalities cited in scientific studies, doctors say the link to Théo’s birth defects is “highly likely”. “I was exposed to glyphosate at a crucial moment in my pregnancy – during the first four weeks,” she says. “I didn’t even know I was pregnant, so I didn’t take any particular precautions.'

New study finds glyphosate causes disease across several generations   (The Organic and non-GMO Report, May 2, 2019)    "But writing in the journal Scientific Reports, the researchers say they saw “dramatic increases” in several pathologies affecting the second and third generations. The second generation had “significant increases” in testis, ovary, and mammary gland diseases, as well as obesity. In third-generation males, the researchers saw a 30 percent increase in prostate disease—three times that of a control population. The third generation of females had a 40 percent increase in kidney disease, or four times that of the controls.  More than one-third of the second-generation mothers had unsuccessful pregnancies, with most of those affected dying. Two out of five males and females in the third generation were obese."

Health and Environmental Groups Call on EPA to Revoke Glyphosate’s Registration  (Beyond Pesticides, September 4, 2019) Sixteen organizations representing health, environmental, farmer, and farmworker communities joined together yesterday to call on EPA to remove glyphosate from the marketplace. The groups cite a combination of high-profile lawsuits, environmental impacts, increasing reports of weed resistance, and growing public concern over the health effects of glyphosate in their comments on EPA’s interim reregistration review decision for the chemical. The comments warn that EPA is at risk of damaging the public’s trust in the agency’s review process for toxic pesticides. The article also ' replies to EPA’s attacks against the World Health Organization’s International Agency for Research on Cancer (IARC).

Unique Hair Testing Project Reveals High Levels of Glyphosate in Members of the Japanese Parliament (Sustainable Pulse, Aug 29 2019)   'The Detox Project’s Director, Henry Rowlands, stated Thursday; “This unique testing project was made possible by the development of new hair testing methods that have enabled our long-term exposure to pesticides to be identified for the first time. Urine and blood testing only give us a very short-term picture of exposure, whereas hair testing gives us the real and full picture of what we have been exposed to over the long-term and thus what we need to avoid.”'  'From the 28 hair samples taken 75% of them tested positive for long-term pesticide exposure, with a total of 14 pesticides being detected.'   'The pesticides detected included Cyprodinil, Fipronil Sulfone, Iprovalicarb, Metolachlor, Propiconazole, Pyraclostrobin, Spiroxamine, Tebuconazole, Tetramethrin, Transfluthrin, Trifloxystrobin, Glyphosate, AMPA, Glufosinate.' out of 60 tested for. 'Four of those pesticides were found in over 10% of the samplesTebuconazole ( a fungicide) – 10.7%, Transfluthrin (an insecticide) – 14.3 %, Glyphosate (a herbicide) – 32.1%, AMPA (the main metabolite of glyphosate) – 53.6%'   'The results for glyphosate and AMPA included regular levels of over 33 and 166 ppb respectively with the highest results of 791 ppb for glyphosate and 1205 ppb for AMPA.'  ''The Japanese Ministry of Agriculture, Forestry and Fisheries reported that 90% of U.S. wheat imports and an even higher % of Canadian wheat imports contain glyphosate residues, mainly due to the practice of pre-harvest spraying'

Don Huber - Glyphosate - Dangers and Soil Remediation (Global Earth Repair conference, May 9, 2019)  Don Huber goes through all the dangers of this defoliant and toxin, why it is so deadly, and how to remove it from bodies and from soil Thank you for your work, Don!!   Over 1 hour video well worth watching. As usual, Huber presents  lots of studies in many fields. Widespread use and history of use, as well EPA 'acceptable levels' in foods being much higher than the levels observed to cause health issue in the lab and in real life. Interesting that when glyphosate replaces glycine in proteins, it causes proteins to fold wrong and adopt a shape characteristic of prion diseases like mad cow diseaseGlyphosate is antibiotic against the good bacteria but, unfortunately, the bad ones (Salamonella.E coli, Clostridium, etc) are resistant. Also presents studies indicating that supplementing bees in areas of severe bee hive loss with water containing minerals and some probiotics can reduce the hive loss from 40%/year to .05%. Part of the solution for livestock diseases is to buy clean feed and supplement minerals. Lots of data from many sources build the case against glyphosate.

Roundup’s Risks Could Go Well Beyond Cancer   Evidence of the cheap herbicide’s danger to biological functions and the environment continues to mount. Why are U.S. regulators not listening?  (By Mark Buchanan, Bloomberg Opinion, June 4, 2019)  'Both the EPA and the EFSA relied on information provided by researchers linked to the industry and considered studies provided by the industry that were not peer-reviewed or made public. The IARC relied solely on publicly available peer-reviewed research.'  ' In both the U.S. and Europe, the supposedly safe limits for human ingestion are based on long-outdated science. Research also points to serious adverse consequences for the environment, and there are indications glyphosate can cause disease in mammals even several generations removed from the initial exposure.'   SNAP comment: The article does not answer its question other than pointing out the narrow scope of studies which regulatory agencies evaluate. I can add the mandatory 'risk-benefit assessment' where use is considered a benefit and need and trumps any negative health and environmental effects. This, in my view, is 'long outdated science', as well as the belief that there is a 'safe' dose at which there is no effect, and the unscientific way this is calculated.

U.S. Health Agency Concurs with International Findings Linking Weed Killer Glyphosate to Cancer, while Inspector General Investigates Misconduct at EPA   (Beyond Pesticides, April 23, 2019)   'But despite the attempts of an apparently corrupt EPA official, earlier this month DHHS’ Agency for Toxic Substances and Disease Registry (ATSDR) released its first draft on the Toxicological Profile for Glyphosate. Top-line findings appear consistent with conclusions made by the World Health Organization’s International Agency for Research on Cancer (IARC) on the carcinogenicity of glyphosate...However, the studies and references analyzed in the report indicate clearly there is strong link between glyphosate and cancer. Of particular note are the three meta-analyses of epidemiological studies reviewed by ATSDR: Schinasi and Leon (2014), Chang and Delzell (2016), and the IARC monograph, which all found “positive associations” between glyphosate exposure and cancer. The Chang and Delzell (2016) study, funded in part by Monsanto itself, downplays in its abstract conclusions that in fact line up closely to the other meta-studies.'

Another Study Links Glyphosate to Cancer  also a link to study. (Beyond Pesticides, March 26, 2019) 'In a study investigating the carcinogenic effects of pesticide exposure by analyzing data on 316,270 farmers and farmworkers in the U.S., Norway, and France, researchers have identified elevated risk for non Hodgkin lymphoma (NHL) and some subtypes, linking glyphosate and large B-cell lymphoma. Other pesticides linked to the disease include the pyrethroid deltamethrin and chronic lymphocytic leukemia/small lymphocytic lymphoma; and terbufos and NHL overall.'  'For this research, chemical groups and active ingredients were selected based on common use in at least two of the three countries. In addition, researchers gave priority to chemical groups and active ingredients for which some associative evidence with lympho-hematological malignancies has already been established, and to active ingredients not previously investigated in epidemiological studies. Glyphosate and dicamba were included in the study, as well as these categorical compounds: four insecticides (organophosphates, organochlorines, carbamates, and pyrethroids); seven herbicides (phenyl ureas, chloroacetanilides, dinitroanilines, phenoxys, thiocarbamates, triazines, and triazinones); two fungicides (dithiocarbamates and phthalimides); and arsenical compounds.

European Court of Justice Orders EU Regulators to Publicly Release Secret Industry Glyphosate Studies (Organic Consumer Association, March 7, 2019)   'The General Court concludes that the requested studies must be regarded as constituting information which ‘relates to emissions into the environment’ and that an overriding public interest in disclosing the studies is deemed to exist. EFSA could not therefore refuse to disclose them on the ground that that would have an adverse effect on the protection of the commercial interests of the owners of the requested studies.'   Original document at:

A Pesticide Distributor, an Insurance Company, a Major City, and a Scientific Study Nix Glyphosate (Roundup)  (Beyond Pesticides, March 15, 2019) . 'First up: Harrell’s is a company that sells chemical pesticides, synthetic fertilizers, and “adjuvants and colorants,” among other products, primarily to golf courses, and to the horticulture-nursery, turf, and landscape sectors. The company announced on March 11 that it stopped selling products containing glyphosate as of March 1, 2019 because neither its current insurance company nor others the company consulted would underwrite coverage for the company for any glyphosate-related claims.'  SNAP Comment: Perhaps the Canadian insurance industry should get on that too.... seems like what a government refuses to do (ban a problematic product) can be achieved by the insurance industry without any backlash.

Study Confirms Findings on Carcinogenic Glyphosate, Suggests “Compelling Link”  (Beyond Pesticides, February 28, 2019)  Statistical analysis revealed there to be a 41% increased risk of NHL resulting from high exposure to glyphosate-based herbicides. To compare and add weight to their results, researchers also conducted a second statistical analysis using older (2005) AHS data, which surprisingly revealed a higher, 45% risk.

The herbicide glyphosate persists in wild, edible plants: B.C. study (RANDY SHORE, Vancouver Sun, February 20, 2019)  'Wood found unexpected levels of glyphosate in new shoots and berries of plants that survived an aerial herbicide application made one year earlier... The 10 species tested were selected for their importance as traditional-use plants, because some First Nations had expressed concerns about the long-term effects of glyphosate on wild plants, said Wood...Glyphosate is typically broken down in soil by microorganisms over a period of months, but how long it persists in living plant tissues is unknown, she said.'

“Safe Levels” Of Exposure Don’t Exist When It Comes To Monsanto’s Glyphosate Poison (The Ring of Fire, Dec 16, 2018)  Interesting and accurate video on the state of research on glyphosate. 'The main ingredient in Monsanto’s Roundup, glyphosate, is not safe, even at levels that the EPA is telling us is safe. Mike Papanotnio and Farron cousins discuss'. SNAP comment: Technically, neither the EPA or the PMRA can say a pesticide is 'safe" because all registered products are designed to kill. What they determine through LD50 (the dose that kills 1/2 fo the animals) put through some equations, is an acceptable dose i.e.a dose at which they don't think negative health effects will occur. Another issue with re-evaluation of pesticide is the people chosen to sit on the re-evaluation committees, many of whom have a long history of contracting with pesticide companies to do 'regulatory science'. The case of 2,4-D re-evaluation for home use in Canada (2005) illustrates that. The committee was formed of 2 industry-related 'experts', 1 PMRA official and 2 epidemiologsts. Studies of cancer in dogs were eliminated, and the cancer ones minimized so it remained on the Canadian market. The pesticide industry previously unsuccessfully tried to re-write the book on epidemiology so the burden of proof would be so high that all studies would be negative. Regulatory pesticide testing was designed decades ago and has not kept up with the science of low dose and endocrine effects so is totally meaningless in that regards.

Common Weed Killer Linked to Bee Deaths  (University of Texas news, Sept. 24, 2018)  "The researchers exposed honey bees to glyphosate at levels known to occur in crop fields, yards and roadsides. The researchers painted the bees’ backs with colored dots so they could be tracked and later recaptured. Three days later, they observed that the herbicide significantly reduced healthy gut microbiota. Of eight dominant species of healthy bacteria in the exposed bees, four were found to be less abundant. The hardest hit bacterial species, Snodgrassella alvi, is a critical microbe that helps bees process food and defend against pathogens...The bees with impaired gut microbiomes also were far more likely to die when later exposed to an opportunistic pathogen, Serratia marcescens, compared with bees with healthy guts. Serratia is a widespread opportunistic pathogen that infects bees around the world."  Also see  Study: Roundup Weed Killer Could Be Linked To Widespread Bee Deaths  (Vanessa Romo, NPR, September 25, 2018)

Glyphosate-based Herbicide Impairs Female Fertility - new study (GM Watch 24 July 2018.)  What the 3 month studies mandated by regulatory agencies cannot show:  The dosages were selected based of the reference dose (dose supposed to be safe over a lifetime) and the higher dose was 1/5th of the "industry-declared no-observed adverse effect level (NOAEL)". 'However, although all glyphosate herbicide-exposed first generation female rats became pregnant, they had a lower number of implantation sites of fertilized eggs, compared with controlsThe second generation offspring from both glyphosate herbicide-exposed groups showed delayed growth, evidenced by lower foetal weight and length, and a higher incidence of abnormally small foetuses...Also, to the authors' surprise, malformations (conjoined foetuses and abnormally developed limbs) were detected in the second generation of offspring from the higher dose of glyphosate herbicide group...The findings of malformations reflect epidemiological findings that people living in an Argentine town in the heart of the GM soy and maize growing area, where glyphosate-based herbicides are sprayed in large amounts, suffer birth defects at twice the national average average rate.' Link to original study and others.  

Press Release: New Study: Glyphosate persists! And European top soils are contaminated with it. (PAN Europe, October 13, 2017)  "45% of Europe’s top soil contains glyphosate residues, demonstrating the over-reliance of the EU agricultural model on this harmful herbicide chemical. In contrast to what its manufactures2 purport, glyphosate persists in soils affecting not only soil fertility and crop quality, but also human and environmental health."   "The concentrations of glyphosate and AMPA found in the study have been shown to be toxic to soil organisms such as earthworms3, beneficial bacteria4 and fungi5 , as glyphosate weakens down plants’ natural defences making them susceptible to pathogens6." 

Glyphosate on feed affects livestock: vet (Western Producer, 19 October 2017)  A veterinarian in Shaunavon, Sask., believes feed with glyphosate residue adversely affects cattle health. Dr. Ted Dupmeier, who operates his own practice at Shaunavon, told about 50 people at a recent event he called an awareness seminar that he began investigating after being unable to diagnose problems in a dairy herd in which cows were inexplicably dying. He said after removing feed that had been sprayed with glyphosate the problems were resolved. SNAP Comment: Positive that this story was actually worth an article in the Western Producer. This "anecdote" supports the facts presented in the video Poisoned Fields - Glyphosate, the underrated risk? (HD 1080p)  (Jan 25, 2016)

Poisoned Fields - Glyphosate, the underrated risk? (HD 1080p)  (Jan 25, 2016)  Glyphosate is the world’s most widely used weed killer. Some claim it is completely harmless, others say it is a serious health hazard for man and animals. A topical investigation into a controversial substance.

Sustained Glyphosate Use Reveals Risks to Soil and Environmental Health  (Beyond Pesticides, July 21, 2017)   Researchers have found that, after years of consistent application to agricultural crops, the chemical accumulates and persists in area soil, particularly at the root zone and in the top few millimeters. In part, the accumulation is due to the fact that only 5% of any applied dose tends to reach the weed it is intended to kill, while the rest lands on the soil. In addition, the chemical is likely released in soil from the roots of plants that have absorbed the compound, as well as from decomposing plants that have been exposed to it. This finding of persistence belies the common assumption that the chemical rapidly degrades in soil.

Continued Use of Glyphosate Herbicide in EU Called into Question by Renowned Toxicologist  (Beyond Pesticides, June 5, 2017)  Dr. Portier asks that the evaluations by EFSA and EChA be “repeated for all toxicological endpoints and the data underlying these evaluations be publicly released.” Based on these failures in data analysis, the final assessments conducted by the EU agencies are insufficient to allow for glyphosate’s license extension, he said...In 2015, Dr. Portier presented at a scientific briefing in London and stated, “Glyphosate is definitely genotoxic. There is no doubt in my mind.” Genotoxicity is the ability of a chemical agent to damage the genetic information within a cell, causing mutations that may lead to cancer. According to Dr. Portier’s presentation, there is strong evidence that glyphosate and its formulated products are genotoxic and an oxidative stressor. Several links.

Monsanto Sued for Misleading Labeling of Popular Herbicide Roundup  (Beyond Pesticides, April 10, 2017) Two nonprofit organizations on Friday filed a lawsuit against Monsanto for misleading the public by labeling its popular weedkiller Roundup as “targeting an enzyme found in plants but not in people or pets.” This lawsuit charges that this statement is false, deceptive, and misleading, because the enzyme targeted by glyphosate, the active ingredient in Roundup, is, in fact, found in people and pets.

Why Is Glyphosate Sprayed on Crops Right Before Harvest? (EcoWatch, 5 March 2016) ...The pre-harvest use of glyphosate allows farmers to harvest crops as much as two weeks earlier than they normally would, an advantage in northern, colder regions...The practice spread to wheat-growing areas of North America such as the upper Midwestern U.S. and Canadian provinces such as Saskatchewan and Manitoba...“It does help hasten dry down and controls grain weeds and other material that slows down the threshing practice," Ransom said. “It has an important role in areas where it's wet." SNAP Comment: This article calls the use of glyphosate prior to harvest dessicationIn Canada, glyphosate is not registered for dessication (or as a dessicant), but for "pre-harvest spraying", which amounts to the same thing without saying the word...For instance the Vantage label indicates to apply at "30% or less grain moisture content. This stage typically occurs 7 to 14 days before harvest." "For control of quackgrass, Canada thistle, common milkweed, toadflax and dandelion; and season-long control of perennial sow thistle, Vantage can be applied prior to harvest of wheat, barley (including malting barley), oats, canola (rapeseed), flax (including low linolenic acid varieties), lentils, peas, dry beans, soybeans and forages. DO NOT apply to crops if grown for seed production."

Monsanto Supporters Admit Massive Fail over Glyphosate Report Criticism (Sustainable Pulse, Nov 28 2016)  Read ful article for links and details. Fail #1: Criticism of testing methodsFolta was forced to withdraw his criticism, which he had already fed to a selection of journalists across the U.S. Fail #2: Misinformation regarding the safety of low levels of glyphosate. Modern independent science has discovered that many toxic chemicals have as much or more of an influence on our health at low doses– these chemicals are known as hormone hackers (endocrine disruptors). Glyphosate is likely to be one of these. Fail #3: Peer Review needed for food testing results? Dr. Folta and colleagues have now taken to stating that they cannot trust the results because they are not peer-reviewed, even though they are all clearly aware of the difference between University studies and commercial laboratory reports.This is a ridiculous line of attack as millions of food samples in the U.S. are tested and reported by FDA-registered laboratories, such as Anresco Laboratories, every single year with no peer-review. SNAP Comments: We may think they have failed but, as long as there are no obligatory endocrine effects for pesticide registration and people believe their BS, they are winning...

EPA Postpones Glyphosate Cancer Review Meeting after Letter from CropLife America (Beyond Pesticides, October 21, 2016)  Last week, the U.S. Environmental Protection Agency (EPA) postponed a long-planned Scientific Advisory Panel (SAP) on the carcinogenicity of the widely used herbicide glyphosate due to “recent changes in the availability of experts for the peer review panel.”  However, as veteran journalist, formerly with Reuters, Carey Gillam reports in the Huffington Post, the move was likely the result of a letter industry front group CropLife America sent to EPA just days before the postponement, challenging the bias of certain experts on the panel. Croplife America is a national trade association that represents manufacturers, formulators, and distributors of pesticides, and has a vested interest in tamping down consumer concerns over glyphosate’s carcinogenicity. SNAP comments: We should all be complaining about the perennial use of industry-sponsored experts on panels. CropLife, both in Canada and the US, acts like if their studies, mosty unpublished, are the only objective one,s while evidence has shown over and over again the industry-bias of industry-sponsored studies.

I guess it prevents the puzzle pieces from fitting properly..."However, EPA indicated that much of the information provided may not impact their current risk assessment for glyphosate, which is expected sometime in 2017." SNAP note: Why not? It does not help that 'industry experts'... usually form the majority (or close to) of any risk assessment committee, it also seems that they EPA's main concern is not public health. I don't think the EPA or the Canadian PMRA have any ideas on how to handle questions outside the very inadequate 'regulatory testing'.

The Real Reason Wheat Is Toxic (it’s Not The Gluten) Gluten may still be a problem as I think modern wheats contain a lot more than old wheats.I was made aware of RoundUp's use for 'pre-harvest' weed control several years ago. In Canada, this is legal, even though RoundUP is not registered as a dessicant. I have also noted many 'dessicated' wheat fields over the years. The tables are interesting. For health, buy organic. Warning if you are a wheat weaver from a friend who said you should avoid dessicated wheat because it breaks rather than weave properly. I have not tested this myself.

Liver and Kidney Damage Tied to Exposure to the Organophosphate Insecticide Malathion   (Beyond Pesticides, November 9, 2018) 'A Tunisian study (published in January 2018) on the effects in pre-pubertal mice of exposure to malathion — an organophosphate pesticide first registered for use in the U.S. in 1956 — demonstrates significant distortion of liver and kidney biochemistry and function in the animals. Deleterious effects include compromise of feeding ability, metabolism performance, neurologic deficits, reduction of overall body weight, and simultaneous increases in the weights of livers and kidneys, with structural anomalies and lesions in those organ.' The article also refers to other recent studies that found deleterious effects of malahion. 'Information from the (EPA) risk assessment was disturbing enough that the EPA took the uncharacteristic step; that information included evidence of histopathological lesions of the nasal cavity and larynx from exposures below the “dose” that typically causes the inactivation of acetylcholinesterase'    SNAP COMMENT:  In 2005, I attended a pesticide session when the SK government was working on the Green Strategy. I was immediately and repeatedly attacked by the Syngenta representative but won every argument. The last one of the day was about malathion. I pointed out that the US EPA had requested studies on the respiratory toxicity of malathion but had apparently not yet received any. The EPA's concern came from the even more widespread spraying of malathion for mosquito control after the West Nile virus scare. He was sure I was out to lunch and promised he would find the info and let me know. No need to say, I never heard from him. The fact is that the standard tests to determine toxicity (dose at which 1/2 of the animals die) for pesticide registration are dermal (skin) exposure and oral (eating the pesticide in food), On toxicity charts, these are the 2 measurements you will find. I have never seen a chart reporting how toxic a pesticide is when breathed in, although it is the most common form of exposure. It appears the US EPA now has received some data allowing them to publish a warning about respiratory exposure.

Toxic Pesticides Found, Again, to Yield No Increase in Productivity or Economic Benefit for Farmers Neonicotinoid-coated (or treated) seeds for soy beans.   (Beyond Pesticides, September 20, 2019) 'The study demonstrates that use of neonicotinoids (neonics) to treat seeds — a very common use of these pesticides — actually provides negligible benefits to soybean farmers in terms of yield and overall economic benefit. The U.S. Environmental Protection Agency (EPA) should take notice, and consider that efficacy ought to have a role in the agency’s evaluation of pesticides for registration.''This new research finding underscores Beyond Pesticides’ advocacy against neonic seed treatment, and duplicates some of the findings of a 2014 EPA report, which said that use of treated soybean seed provided little-to-no overall benefit in controlling insects or improving yield or quality in soybean production.'  SNAP Comment: In all the PMRA's or EPA's cost--benefitassessments, the aalleged benefits always trump any negative effects in the final evaluation. Interesting to see here how little benefits..

Insect “Honeydew” Secretions, Contaminated with Neonicotinoid Insecticides then Eaten by Other Insects, and Birds Contribute to an Expansive Threat  (Beyond Pesticides, August 9, 2019)  'Pollinators such as honey bees, solitary bees, bumblebees, and even birds have been observed feeding on honeydew.'  'Results were bad news for beneficial hoverflies and parasitic wasps. Every hoverfly that ate honeydew from the thiamethoxam-sprayed trees died within three days of exposure, compared to 10% of the control group. Of the hoverflies that consumed honeydew from the trees soil-treated with thiamethoxam, nearly 70% died, compared with 14% for the controls. Results for the parasitic wasps were marginally better: more than 50% died after consuming honeydew from both soil- and foliar-treated trees, compared with less than 20% mortality among controls. The honeydew itself was also evaluated: samples from trees treated with thiamethoxam were highly toxic to both species of beneficial insects, and honeydew from those treated with imidacloprid was moderately toxic to hoverflies.'

Same Pesticides that Are Killing Bees Killed Off Dozens of Goldfinches in Modesto, CA, Study Finds  (Beyond Pesticides, July 17, 2019)   'A March 2017 bird kill incident in Modesto, CA can be traced directly back to an insecticide “soil drench” applied to the base of several elm trees by pesticide applicators hired by the city... Researchers autopsied the birds, finding elm seeds and detectable levels of imidacloprid in the gizzard contents (between 2.2-8.5 ppm) and liver tissue (between 2.1-4.8 ppm) of the affected goldfinches, consistent with the presence of imidacloprid on elm seeds found around soil drenched trees....The City of Modesto indicates that applicators followed the label correctly. Consequently, this incident points to a serious, but not unexpected, shortfall in the U.S. Environmental Protection Agency’s (EPA) regulation of toxic pesticides.

Study Finds Synergism between Neonicotinoids and Parasites Leads to 70% Declines in Honey Bee Survival  (Beyond Pesticides, June 24, 2019)   After 42 days of spring exposure to neonicotinoids at environmentally relevant concentration, 'researchers looked for differences in response to neonicotinoid exposure depending on individual bees’ status – whether or not they were harboring mites – which varied naturally among individuals in each colony.' 'By the time autumn collections were completed, combined exposure to neonicotinoids and V. destructor were found to cause an astounding 70% reduction in survival, significantly surpassing the effects of either exposure alone. These results have strong implications for overall colony survival.'

As Pesticide Turns Up in More Places, Safety Concerns Mount  A growing body of research is challenging the assumption that neonicotinoids are safer and less likely to spread than other pesticides   (By Jim Daley, Scientific American, April 30, 2019)   'Only 2 to 20 percent of the neonicotinoids applied to seeds make it into the plant, says Jonathan Lundgren... “And we’re starting to find (the other 80-98) in other areas of the environment like surface waters and untreated plants.'  Several of the studies referred to in the article are already on SNAP's web site under wildlife but there is mention of others. Neonicotinoids have also been widely found in foods.  "Morrissey says the problem is not as simple as banning one pesticide or another, though. '“The bigger problem is that we’ve become complacent about using pesticides for everything,” she says. Lundgren says 'meaningful change will have to come from grassroots efforts.'

In any case, it is likely that the test used in this study is part of the mandated tests as the list dates from 1984.

Scientists warn about the dangerous interaction of plant protection products (ESTONIAN RESEARCH COUNCIL, 12 MAR-2019)   'Using a hymenopteran parasitoid wasp Aphelinus abdominalis (a globally distributed species widely used in biocontrol) as a model, a team of researchers showed the enhanced effect of a low-concentration insecticide (thiacloprid) treatment when combined with various concentrations of a fungicide (tebuconazole). 'SNAP Comment: It is absolutely correct that pesticides are only evaluated one at a time, even when regularly used as a mixture like lawn chemicals (2,4-D,, mecoprop and dicamba)

Drinking Water Contaminated with Neonicotinoid Insecticide Byproducts  (Beyond Pesticides, February 8, 2019)  'The experts discovered two metabolites of imidacloprid (a neonicotinoid insecticide) residues that had not previously been identified in drinking water — desnitro-imidacloprid and imidacloprid-urea. The researchers note both that these metabolites have never been evaluated for their potential risks to human and environmental health, and that there may be potential risks of anthropogenic compounds that can be created when water with neonicotinoid residues, and thus, these metabolites, undergo typical water treatment (often chlorination and/or pH treatment)...The presence of neonics in drinking water is concerning per se, because federal regulators have never addressed what might be “safe” levels of such insecticides in tap water,

Occurrence of Neonicotinoid Insecticides in Finished Drinking Water and Fate during Drinking Water Treatment   (Kathryn L. Klarich et al, Environ. Sci. Technol. Lett., 2017, 4 (5), pp 168–173, April 5, 2017)  'Neonicotinoid insecticides are widespread in surface waters across the agriculturally intensive Midwestern United States. We report for the first time the presence of three neonicotinoids in finished drinking water and demonstrate their general persistence during conventional water treatment...Clothianidinimidacloprid, and thiamethoxam were ubiquitously detected in finished water samples at concentrations ranging from 0.24 to 57.3 ng/L Samples collected along the University of Iowa treatment train indicate no apparent removal of clothianidin or imidacloprid, with modest thiamethoxam removal (∼50%). In contrast, the concentrations of all neonicotinoids were substantially lower in the Iowa City treatment facility finished water using granular activated carbon (GAC) filtration. 

Study Finds Bumblebees Increasingly Attracted to the Pesticides that Kill Them  (Beyond Pesticides, August 31, 2018)  'the study indicates that bees may be undertaking the human equivalent of chain-smoking themselves to death.'  'By the end of the experiment, food containing 2 parts per billion of the pesticide was eaten 10% more than in the beginning of the study. Researchers changed the location of the nectar sources throughout the experiment, but bumblebees still sought out the toxic food.'

Amsterdam Leads Bee Recovery Efforts by Banning Bee-Toxic Pesticides, Improving Habitat  (Beyond Pesticides, September 12, 2018)  "A new map published by the city identified 21 bee species not found in an earlier 1998 survey recorded by Amsterdam officials. The increase has been attributed to a range of pollinator-protective measures, including a ban on bee-toxic pesticides and the planting of native flowers, prioritized by the... city government since the turn of the century."  "While the EU recently made indefinite a ban on bee-toxic neonicotinoid insecticides in agriculture, urban spaces have been singled out for the continued risk to pollinators posed by the lawn and garden use of these chemicals. Amsterdam appears to have successfully made up the difference, banning the use of bee-toxic neonicotinoid insecticides on public city property, and encouraging residents and businesses to eliminate their use through brochures and informational pamphlets. Neonicotinoids have been implicated in the decline of wild and managed pollinators, leading governments, both large and small, to impose restrictions on their use.'SNAP Comment: Similarly, I think the proposed Canadian ban of 3 neonicotinoids is mostly on farmland. If it covers outdoor uses, it would still mean that neonicotinoids would make their way to the consumers and the environment through allowed "indoor use" in greenhouses, presumably on food and bedding plants.

Has Ottawa sold out to Big Agro and its toxic chemicals?   (By Bruce Livesey, Canada's National Observer, July 25th 2017) (#1 of 2 articles from the Special Report: Bureau of Poison) SNAP Comment: If pesticides work, why are we using more and more every year? Well researched article.  'According to Statistics Canada, the area of farmland treated with herbicides, insecticides and fungicides increased by 3 per cent, 42 per cent and 114 per cent respectively between 2001 and 2011. In Canada, 100 million kilograms of pesticides were sold in Canada in 2014 – up from 82 million kilograms in 2009.'... 'However, the Auditor General of Canada has carried out three investigations... into the PMRA since 2003 — and found it wanting.' 'In response to the Auditor’s 2015 report, last year the PMRA announced it was going to stop giving conditional registrations – but only on new pesticides, not those currently on the market. This winter, Health Canada began considering phasing out one class of neonicsimidacloprid, due to its impact on aquatic insects – but only over a three-to-five year time frame. '  "Rarely will (PMRA) take a pesticide off the market,” says Cooper. “They will tweak the label or they will add additional requirements or mitigation for the workers or application rates… But you never get to ‘Boy, this thing is bad news’.”    'But more significantly, the PMRA uses a “risk-based” assessment model that critics believe ensures no pesticide could ever be banned. But more significantly, the PMRA uses a “risk-based” assessment model that critics believe ensures no pesticide could ever be banned.

Popular nicotine-based pesticides pose risk to aquatic insects: Health Canada  (By Kelsey Johnson, ipolitics, Aug 15, 2018)  'Scott Kirby, director general for Health Canada’s Pest Management Regulatory Agency, told reporters the phasing out of all outdoor uses of the neonicotinoid pesticides (thiamethoxam and clothianadinwould occur over three to five years, once the ban is approved. Midges and mayflies are a key food source for birds and fish. The agency started its review of the two pesticides in November 2016. The length of the phase-out, currently subject to a 90-day consultation period, will depend upon whether alternative products are available. PMRA proposed a ban on outdoor uses of imidacloprid in November 2016 amid concerns about the health of mayflies and midges. A final decision is expected in December 2018, Kirby said. None of the proposed bans are currently in effect. All are subjected to public consultation. Final decisions on whether to ban thiamethoxam and clothianadin are expected in 2019.'  SNAP Comment: In their own words, it does not matter how toxic a product is, it has to have a replacement "product' before it is banned. In the meantime, God forbid they ever consider that the 'product' may not be needed at all under other methods of farming that protect biodiversity. The good news is that we can still contribute comments to the public consultation.

Trump administration lifts ban on pesticides linked to declining bee numbers   'The rollback, spelled out in a US Fish and Wildlife Service memo, ends a policy that had prohibited farmers on refuges from planting biotech crops – such as soybeans and corn – engineered to resist insect pests and weed-controlling herbicides.That policy also had barred the use on wildlife refuges of neonicotinoid pesticides, or neonics, in conjunction with GMO crops. Neonics are a class of insecticides tied by research to declining populations of wild bees and other pollinating insects around the world.'

Suburban Bees Still Vulnerable to Neonicotinoids Despite EU Ban  (Beyond Pesticides, August 1, 2018) According to new research from the University of Sussex, bees living in suburban habitats are still being exposed to high levels of neonicotinoid pesticides. Even though there is a European Union (EU) ban on these chemicals, the ban focuses on agricultural and not residential applications. The study’s authors are urging gardeners to forgo the use of these pesticides in favor of more holistic, pesticide-free approaches. 'The authors of the study say it is the first of its kind to highlight the risk to bees in urban areas posed by garden use of pesticides. Entitled Monitoring neonicotinoid exposure for bees in rural and peri-urban areas of the UK during the transition from pre- to post-moratorium, the study sampled pollen and nectar from bumblebee colonies in rural and peri-urban habitats ... over three years. Sampling began prior to the ban (2013), during the initial implementation when some seed-treated winter-sown oilseed rape was still grown (2014), and following the ban (2015). Honey bee colonies in rural habitats were also sampled to compare species-level differences between bumblebees and honey bees.'  SNAP comment: I am not aware of any Canadian study looking at the concentration of neonics in pollen and nectar in urban areas. However, a recent study looking at pesticide contamination of bedding plants have found commercial bedidng plants to be widely contaminated with neonics. In Canada, a quick search (5 August 2018) of the PMRA domestic formulations for a few neonicotinids found many Canadian registered neonicotinoids for treating fleas and lice on pets, but also for ant treatment indoors and out. Many neonicotinoids are licensed for  professionals to use in greenhouses and nurseries insects in lawn, fruit and ornamental trees. Any commercial applicator can use some for treating your lawn, trees or landscape. 

Costco takes stand on insecticides  (Western Producer, 5 July 2018)  'The grocery store chain, with more than 600 stores in the United States and Canada, said in May that it wants producers of fruits, vegetables and garden plants to stop using neonicotinoids, a class of insecticides commonly known as neonics.' 'Suppliers are encouraged to phase out the use of neonicotinoids and chlorpyrifos (an insecticide),” Costco said on its website.'“We seek to partner with suppliers who share our commitment to pollinator health and IPM (integrated pest management).”  SNAP comment: good news. I hope it covers all neonics not only imidacloprid which may be banned by Canada. I don't understand how the PMRA can conclude that a systemic pesticide can be systemic only in some uses. It defies logic: '“Certain uses of products containing imidacloprid result in uptake by plants where it then moves into nectar and/or pollen,” said Scott Kirby, director general of environmental assessment with Health Canada’s Pest Management Regulatory Agency.'

Neonicotinoids may alter estrogen production in humans (INRS,April 26, 2018,/ by Stéphanie Thibault)   An INRS team publishes the first-ever in vitro study demonstrating the potential effects of these pesticides on human health in the journal Environmental Health Perspectives...The results of the study show an increase in aromatase expression and a unique change in the pattern in which aromatase was expressed, which is similar to that observed in the development of certain breast cancers.

Study disputes popular pesticides’ effectiveness (Globe and Mail, 26 Feb.2018)'A new study raises questions about the effectiveness of the two most popular types of agricultural pesticides, noting overreliance on the chemicals causes environmental harm while doing little to boost crop yields.'..The new paper reviewed more than 200 studies. Researchers found other methods of pest control are more effective and less harmful to the environment. In addition to crop rotation, these methods include planting pest-resistant crops and the purchase of insurance, which is less expensive than pesticides. The paper's authors said they studied neonicotinoids and fipronil because they together hold the largest share of pesticides used around the world. But they cautioned that other pesticides pose threats to the environment and public health.'

Long-term yield trends of insect-pollinated crops vary regionally and are linked to neonicotinoid use, landscape complexity, and availability of pollinators (Heikki M. T. Hokkanen et al,  Arthropod-Plant Interactions, June 2017, Volume 11, Issue 3, pp 449–461, First Online: 21 April 2017) a Finnish study. 'It appears that only the uptake of neonicotinoid insecticide seed dressing about 15 years ago can explain the crop yield declines in several provinces, and at the national level for turnip rapeseed, most likely via disruption of pollination services by wild pollinators.' 

A worldwide survey of neonicotinoids in honey   E. A. D. Mitchell1,2,* et al  (Science  06 Oct 2017: Vol. 358, Issue 6359, pp. 109-111)   We assessed the global exposure of pollinators to neonicotinoids by analyzing 198 honey samples from across the world. We found at least one of five tested compounds (acetamiprid, clothianidin, imidacloprid, thiacloprid, and thiamethoxam) in 75% of all samples, 45% of samples contained two or more of these compounds, and 10% contained four or five. 

Neonicotinoid Seed Coatings Create Exposure Hazards for Honey Bees and Fail to Increase Yields  (Beyond Pesticides, May 31, 2017) This article deals with corn and soy. In Saskatchewan, most of our canola is treated with neonics and U of S studies have shown widespread contamination of sloughs. “There was a misconception that any bees not living near corn were likely to be fine. But that’s not true, and it’s clear that these insecticides are reaching into the places bees forage and putting them at risk.” The research team set up neonic dust collection traps at 12 corn fields around Indiana and collected samples over two years to determine the levels of pesticide dust at increasing distances from the corn field edges. The data demonstrate the movement of neonic residues outside the borders of planted fields, and the researchers estimate that residues on non-target lands and waterways will be deposited on over 42% of the state of Indiana during the corn planting season." 

Common pesticide damages honey bee's ability to fly  (phys.org. April 26, 2017) 

Common pesticide damages honey bee's ability to fly (phys.org. April 26, 2017)  A study published April 26 in Scientific Reports by UC San Diego postdoctoral researcher Simone Tosi, Biology Professor James Nieh, along with Associate Professor Giovanni Burgio of the University of Bologna, Italy, describes in detail how the neonicotinoid pesticide thiamethoxam damages honey bees. "Our results provide the first demonstration that field-realistic exposure to this pesticide alone, in otherwise healthy colonies, can alter the ability of bees to fly, specifically impairing flight distance, duration and velocity" said Tosi. "Honey bee survival depends on its ability to fly, because that's the only way they can collect food. Their flight ability is also crucial to guarantee crop and wild plant pollination."  another article on same topic Neoniocotinoid Pesticides Impair Bees’ Ability to Fly (Beyond Pesticides, May 3, 2017)

Report Documents Threats to Aquatic Life, Calls for Phase-Out of Neonicotinoid Use  (Beyond Pesticides, April 14, 2017) – As pollinators nationwide suffer severe declines tied to widespread exposure to pesticides, particularly a family of insecticides known as neonicotinoids, a new report details the chemicals’ dramatic impacts on aquatic ecosystems and biodiversity. This report coincides with findings of neonicotinoids in drinking water.The new report, Poisoned Waterwaysdocuments the persistence of neonicotinoids in U.S. waterbodies and the danger they cause to aquatic organisms, resulting in complex cascading impacts on aquatic food web. The report supports previous calls for the restriction of neonicotinoid pesticides, given their high toxicity to bees, and now aquatic life. Poisoned Waterways reviews the current scientific literature on the effects of neonicotinoids in waterways and the life they support. The report also highlights current regulatory failures of EPA aquatic standards, which continue to underestimate risks to sensitive species due to a reliance on test protocols that do not reflect real-world exposures or susceptibilities. Further, the impacts of chemical mixtures and synergistic interactions are not considered.

By Killing Beneficial Insects, Neonic-Coated Seeds Increase Pesticide Dependency, Just Like Other Insecticide Applications (Beyond Pesticides, December 16, 2016)  A new meta-analysis has challenged the belief that neonicotinoid (neonic) insecticide seed coatings have little to no effect on the health of beneficial predatory insect populations —on the contrary, researchers have found that the seed coatings impact predatory insects as much as broadcast applications of other insecticides...As predicted, the population of predatory insects are reduced in the plots where coated seeds are planted, compared to the plots that are untreated by insecticides. Additionally, the meta-analysis finds that coated seeds affected predatory insect populations similarly to soil and broadcast applications of pyrethroids.

Expert panel: Should we ban neonicotinoid pesticides? (Evidence for Democracy) "The current scientific evidence on the negative impacts of neonicotinoids on wildlife is very compelling and is growing rapidly. There are numerous peer-reviewed studies showing lethal and sublethal effects on a variety of taxa... As Canadians, I believe we should be thinking about where are agricultural sector is heading and what the implications are for biodiversity and human health."Sheila R. Colla

Half of the Total Decline in Wild Bees throughout the UK Linked to Use of Neonics (Beyond Pesticides, August 18, 2016)  Decline of wild bee populations is linked to the use of toxic, systemic neonicotinoid (neonic) pesticides used on oilseed rape (canola), according to new research done by a team of scientists at the Centre for Ecology and Hydrology in the United Kingdom.The study, Impacts of neonicotinoid use on long-term population changes in wild bees in England, published in the journal Nature Communications, analyzed 18 years of UK national wild bee distribution data for 62 different species, and related it to amounts of neonicotinoid use. NOTE: Interesting for Saskatchewan as canola is a major user of neonic seed treatment.

Insecticides Similar to Nicotine Found in about Half of Sampled Streams across the United States 8/18/2015.U.S. Geological Survey.USGS discovered insecticides known as neonicotinoids in a little more than half of both urban and agricultural streams sampled across the United States and Puerto Rico, according to a study by the agency published today in Environmental Chemistry. “In the study, neonicotinoids occurred throughout the year in urban streams while pulses of neonicotinoids were typical in agricultural streams during crop planting season,” said USGS research chemist Michelle Hladik, the report’s lead author.

Neonicotinoids Hinder Bee’s Ability to Smell Flowers (Beyond Pesticides, June 29, 2015)...'a neonicotinoid pesticide, at sublethal doses, harms this odor memory formation,” Chinese Academy of Science’s Ken Tan, who led the study, told CBS News in an email interview.' 'Published in Nature on June 18, 2015, the study finds that “adults that ingested a single imidacloprid dose as low as 0.1 ng/bee had significantly reduced olfactory learning acquisition, which was 1.6-fold higher in control bees. Bees exposed as larvae to a total dose of 0.24 ng/bee had significantly impaired olfactory learning when tested as adults; control bees exhibited up to 4.8-fold better short-term learning acquisition.” Researchers conclude that this sublethal cognitive deficit caused by low dose exposure to neonicotinoids on a broad range of bee species is cause for further study. also published under Bee Die-off.

This very informative scientific talk was prepared for the Office of the Science Advisor Webinar Series of the U.S. Fish and Wildlife Service. To be added to the webinar series contact megan_cook@fws.gov  It reviews neonicotinoids, how they behave and their persistence in the environment, as well as their environmental as well as immune suppressing and other health effects. It relates the precipitous decline in butterflies with the increased use of neonicotinoids. Complicated science made simple. Good references. 

New Study Exposes Range of Harm from Neonicotinoid Pesticides (Beyond Pesticides, June 18, 2013)   Soil half-life of the most commonly used seed treatments can range from 200- 1000 days. Clothianidin has the potential to remain in soil for 6,931 days (nearly 19 years!) before degrading .“Studies from the US suggest that neonicotinoid seed dressings may be either entirely ineffective or cost more than the benefit in crop yield gained from their use. We seem to be in a situation where farmers are advised primarily by agronomists involved in selling them pesticides.” says Dr Gouslon.

Be aware of pre-harvest herbicide application restrictions (Western Producer, Aug. 1st, 2015 by Thom Weir PAg) This article lists the herbicides registered in Canada for 'pre-harvest' use equivalent to dessication (without using the term dessication), and their use restrictions. SNAP Comment: I assume the articie is accurate as to date of publication. I have not yet been able to find if there are more regulatory requirements in registering a dessicant than a herbicide. Also see Glyphosate section above.

Sulfonylurea herbicides

 I decided to add this page because I learnt some pesticide formulations containing sulfonylureas are still in use, including Clear for the control of Wild Parsnip in Ontario where a recent incident involved the soaking of a farmer sitting on his tractor while trying to get out of his yard. Too many individual herbicides to check for registration, I am afraid, but I am providing a list of names.

The fact that they cause total or almost total crop failures in fruit trees and strawberries was on the news in the early 1990s but now no one talks about it. It likely still occurs. You should be aware of it and so should anyone using it. 

'Sulfonylureas (UK: sulphonylurea) are a class of organic compounds used in medicine and agriculture... A large number of sulfonylureas are used as herbicides.

Sulfoxaflor and flupyradifurone: Neonicotinoids or not ?

view details »

Because of this detailed factsheet, articles about these 2 chemicals will be under the neonicotinoid section of this page from now on. This is an important distinction because, as neonicotinoids are shown to have such a massive effects on pollinators, companies want to keep on  registering insecticides with the same mode of action without the bad press of calling them neonicotinoids. France, which banned many neonicotinoids, has recently approved those two because the regulators have been fooled. There is currently (November 2017) a campaign to ask for France to 'Ban all bee-killing pesticides!' Please consider signing and sharing. 

Sulfoxaflor and flupyradifurone:  Neonicotinoids or not ? (PAN Europe, Sept 2016)

The pesticide industry is trying to hide the reality behind two new chemicals that are similar to the notorious group of neonicotinoids linked to massive bee death all over the world.
Their properties clearly show that they should be classified as neonicotinoids.

General conclusion
This factsheet has demonstrated how pesticide companies make use of pseudo-science to give their new pesticides a more positive image. In the frame of the ever greater interest of the general public in the relation between pesticide use and health damage, including bee health, the fact that pesticide companies themselves decide what category a pesticide belongs to, for mere regulatory or marketing purposes should not be authorised.
Sulfoxaflor and flupyradifurone are neonicotinoid insecticides. They should be treated accordingly by regulator, taking into account their systemicity and the harm they could cause to non-target organisms such as bees.
