US court bans three weedkillers and finds EPA broke law in approval process

US court bans three weedkillers and finds EPA broke law in approval process   Ruling, specific to three dicamba-based weedkillers, is major blow to Bayer, BASF and Syngenta (The Guardian, 7 february 2024)

'The ruling is specific to three dicamba-based weedkillers ... which have been blamed for millions of acres of crop damage and harm to endangered species and natural areas across the midwest and south.

This is the second time a federal court has banned these weedkillers since they were introduced for the 2017 growing season. In 2020, the ninth circuit court of appeals issued its own ban, but months later the Trump administration reapproved the weedkilling products, just one week before the presidential election at a press conference in the swing state of Georgia.

Bury wrote that the EPA did not allow many people who are deeply affected by the weedkiller – including specialty farmers, conservation groups and more – to comment.

The EPA first approved Monsanto and BASF versions of dicamba touted to be less likely to move off target for the 2017 growing season. Since then, dicamba has caused millions of acres of crop damage, and has been the subject of several lawsuits.

In February 2020, a federal jury in Missouri awarded the state’s largest peach farmer $265m for damage to his farm, though that total was later reduced by a federal judge. In June 2020, Bayer announced a $400m settlement with soybean growers that had been damaged by non-target drift.

For years, Bayer and BASF have blamed other factors than their weedkillers, including illegal use of older chemicals, for the damage. Discovery documents turned up in the litigation showed the companies knew that their dicamba weedkillers would probably lead to off-target crop damage.'

SNAP Comment: There was no public notice and comment as required by law. Note that even when there is, and opponents present their evidence and independent studies, this evidence is usually discounted in favour of industry studies. Cost-benefit evaluations tend to inflate benefits and discount costs.

Ending glyphosate is a virtuous goal, and reducing pesticides is essential (Prevent Cancer Now, 2023) with a quick review of several registered pesticides of concern. The Federal Government  (Canada) response to the Parliamentary Petition indicates no plan to support substantially lower-input and organic practices, to achieve substantial reduction in pesticides use and risk.

 a stated goal of the UN Biodiversity Conference (COP-15), in Montreal this December, is to reduce pesticides by two thirds.

Polyfluorinated pesticides and PFAs 

Some pesticides contain fluorine and some formulants (inerts) are fluorine based. In addition, at least HDPE plastics used in containers (i.e.for food and pesticides) contain them as well, and they are now known to leach from these containers into the content. The leaching is worse in products formulated in organic solvents such as methanol compared with water-based products. For both solvents tested (methanol and water), the study also shows continued gradual leaching of PFAS over time according to the EPA. Some pesticides contain a trifluoromethyl group that end up breaking off and forming ozone-depleting chemicals.It is apparently had to get information on that topic.

Per- and Polyfluoroalkyl Substances (PFAS) in Pesticide and Other Packaging (US EPA, updated 5 December 2023) This page describes EPA actions at all levels for these chemicals. 'In December 2022, the Agency issued a notice announcing the removal of 12 chemicals identified as PFAS from the current list of inert ingredients approved for use in nonfood pesticide products to better protect human health and the environment. These chemicals are no longer used in any registered pesticide product.'

A brand new “Frankenstein” herbicide – Tiafenacil

Tiafenacil is a new fluorine-containing herbicide, that inhibits a key enzyme to make chlorophyll.

A brand new “Frankenstein” herbicide – Tiafenacil

(Prevent Cancer Now) scroll down the page.

Tiafenacil is a new herbicide, that inhibits a key enzyme to make chlorophyll.

Tiafenacil features several biologically-active, toxic groups, that are combined in a large molecule—a bit like a “Frankenstein” chemical.

This degrades into smaller molecules of toxic chemicals. For example, the top group with three fluorine atoms separates to form highly persistent trifluoroacetic acid. The PMRA found that young children would exceed the maximum allowable daily intake, then stated that is deemed to be acceptable because the assessment is “conservative.” This is hard to understand, given that the extrapolation (a.k.a. “safety”) factor for sensitive populations was eliminated, and there is no human data on this brand new pesticide.

SNAP Comment: As of 23 January 2024, 4 tiafenacil herbicides are registered by the PMRA for use in a variety of crops.

P.E.I. potato growers have new pesticide to fight wireworm

Broflanilide, containing several trifluoromethyl groups that will likely contribute to ozone depletion

P.E.I. potato growers have new pesticide to fight wireworm (Broflanilide)
Potato board estimates cost of wireworm damage to crops at $5 million a year  (Nancy Russell ,CBC, Posted: Mar 04, 2021)   Chemical Formula: C25H14BrF11N2O2.  Chemical name: 3-(benzoylmethylamino)-N-2-bromo-4-1,2,2,2-tetrafluoro-1-(trifluoromethyl)ethyl-6-(trifluoromethyl)phenyl-2-fluorobenzamide.   This product contains several trifluoromethyl groups that will likely contribute to ozone depletion.  

SNAP COMMENT: perhaps it is different in large scale plantings, but in my organic garden, the only potatoes that ever get wireworm damage are the ones planted near the outside grass. When I edge in spring, I used to throw the grass rhizomes on top of the soil to dry up, until I found sereval wireworms seemingly living in there so now rhizomes are thrown on the grass and I have very little problems. Also PEI has an imported wireworm that may behave differently.

Field Study of Bumble Bees Finds Exposure to Chemical Mixtures, High Hazard, Flawed Regulation

Field Study of Bumble Bees Finds Exposure to Chemical Mixtures, High Hazard, Flawed Regulation

(Beyond Pesticides, January 9, 2024) A “landscape-level” study finds that typical risk assessment studies used by the U.S. Environmental Protection Agency (EPA) and European regulators fail to “safeguard bees and other pollinators that support agricultural production and wild plant pollination.” The study, published in Nature (November 2023), evaluates the health of bumble bees (Bombus terrestris) as a sentinel species placed in 106 agricultural landscapes across Europe. 

The study found a combination of insecticides and fungicides, including ten compounds found in colony pollen stores, which the authors consider to present the highest risk, based on acute toxicity. The ten pesticides (nine insecticides and one fungicide) include indoxacarb, spinosad, chlorpyrifos-ethyl, deltamethrin, dimethoate, imidacloprid, cyfluthrin, dithianon, etofenprox, and chlorpyrifos-methyl. Concern about impacts on bees extends beyond acute effects to a range of adverse impacts, including disorientation, other sublethal effects, reproductive effects and development delays, and vulnerability to disease and mite infestation.

 “Without knowledge of safe environmental limits, the total pesticides used—and therefore the total environmental dose—is governed by market demand rather than by a limit on what the environment can endure.” Standard toxicity tests on individual pesticides, according to the authors, is of “limited use” when considering wide, “diffuse environmental effects that arise from ecosystem connectivity at a landscape scale.” The study in Nature adds to the empirical evidence of devastation wrought by pesticides and the ineffectiveness of current European as well as U.S. regulatory approaches...   The failure of EPA to consider the effect of pesticide mixtures in the environment extends to the formulation of pesticide products.'

SNAP Comment: The PMRA does not consider the effects of mixtures either. There are 0 indoxacarb, 23 spinosad, 0 chlorpyrifos-ethyl,19  deltamethrin, 7 dimethoate (Cygon),102 imidacloprid, 10 cyfluthrin, 0 dithianon, 2 etofenprox, and 0 chlorpyrifos-methyl registered in Canada as of now.. Historically, there are over 200 chlorpyrifos prrducts registered. Some may still be in use, as the PMRA only regulates sales, not use.

Work-Related Pesticide Exposure Puts Farmers at Risk of Cognitive (Intellectual) Harm

(Beyond Pesticides, January 4, 2024) A review published in the Journal of Neurosciences in Rural Practice finds an association between farmers’ pesticide exposure and cognitive impairment. Specifically, farmers suffer from attention deficit, lack of information processing, non-comprehension of verbal cues, slow processing speed, memory loss, sluggishness, speech difficulties, and impaired motor function. Additionally, the risk of adverse effects from exposure increases with time spent around pesticides, like in other occupational (work-related) settings.
