Laboratory reports commissioned by PEER found PFHxS (perfluorohexanesulfonic acid), PFHxA (perfluorohexanoic acid), PFBS (perfluorobutanesulfonic acid), and PFOS (perfluorooctanesulfonic acid) in all twelve samples of Rejuvra™ tested. [1] The herbicide’s active ingredient is indaziflam, a pre-emergent fluoroalkyltriazine compound used to control annual grasses and broadleaf weeds in residential, commercial, forestry, and agricultural settings. [2]
PEER stated that the herbicide ‘is being sprayed and considered for use across millions of acres of Bureau of Land Management (BLM) and US Forest Service land.’ [2] The group’s press release noted that the product label lists indaziflam as the sole active ingredient, making up 19.05% of the formulation. The remaining 80.95% is categorized as ‘Other Ingredients’ or ‘inert ingredients,’ which are not disclosed to the public.
