Polyfluorinated pesticides and PFAs 

also see fludioxonil, flupyradifurone

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.

New herbicide for weed control in wheat registered    (By Farmtario Staff, January 25, 2024)   'The company said in a release Batalium combats weed-related losses across all soil zones. Its formulation features four powerful active ingredients from three modes of action, providing an easy-to-use tool for optimal results.'  

Batalium info: The following is provided by Meg Sears of Prevent Cancer Now: 'Batalium is a newly approved herbicide (tech sheet here), that is a mixture of three old herbicidesFlucarbazone-sodium – Group 2, Fluroxypyr – Group 4, and Bromoxynil – Group 6.Batalium is "Compatible with over 23 registered tank-mix partners, BATALIUM AMPED herbicide lets you customize your weed management program based on weed pressure and application conditions."   Acutely toxic, Health hazard, and Environmental hazard, Irritant   These three herbicides include the -C-F3 group that will break off and affect the ozone layer, as well as halogenated ring structures that typify endocrine disruptors.'

A brand new “Frankenstein” herbicide – Tiafenacil (Prevent Cancer Now) scroll down the page.     

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)
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. 

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.'

EPA confirms PFAS can leach from shipping containers into food, other products   (By Shannon Kelleher, The New Lede, 12 September 2022)    Toxic chemicals knowns as PFAS leach from the walls of shipping containers into the products they contain, potentially contaminating food, pesticides, and other products transported all over the world, according to study by the Environmental Protection Agency (EPA). The EPA analysis found that 8 types of PFAS compounds leached into water and methanol samples stored in fluorinated high-density polyethylene (HDPE) containers after just one day. The EPA said the analysis provided “a clear indication” of the migration of PFAS from container walls to the liquid solutions in the container.  The agency said the amount of PFAS leached into the solutions generally increased with time during the agency’s 20-week testing period.The levels of contamination the EPA found were far higher than the updated drinking water health advisory level of about 0.004 parts per trillion (ppt) that EPA recently set for PFOA, one of the PFAS chemicals identified in the barrels. 'SNAP Comments: Canadian Water guidelines for PFAs (June 2019)  'Treatment options for PFAS: PFAS can be removed by treating well water: using either an activated carbon filter installed at the tap or where the water enters the house; or using a reverse osmosis system installed at the drinking water tap. Reverse osmosis systems should only be installed at the tap, as the treated water may cause corrosion to the plumbing and cause other contaminants, like heavy metals, to leach into the water.'
