Outrage Erupts After Elementary Herbicide Spraying Sickens Dozens of Students in Stanislaus County
By Robert Thorne
Cornerstone Plus is widely used in commercial farming and rights-of-way weed abatement. Classified as a non-selective systemic herbicide, the formula eradicates broadleaf weeds and grasses by inhibiting the EPSP synthase enzyme pathway, preventing plants from producing essential aromatic amino acids. Its primary active component is glyphosate, formulated as an isopropylamine salt at a concentrated 41% loading.
Glyphosate alone rarely causes immediate, blistering epidermal reactions. The severe weed killer skin irritation observed in Stanislaus County stems primarily from the formulation's inert additives. Cornerstone Plus contains an aggressive surfactant package, frequently polyethoxylated tallow amine (POEA) derivatives or proprietary ethoxylated surfactants. These chemical adjuvants strip the waxy protective cuticles off tough invasive weeds so the glyphosate can penetrate plant vascular systems.
When sprayed near humans, that same mechanism compromises the human skin barrier. Surfactants dissolve epidermal lipids, triggering rapid dermal inflammation, ocular burns, and mucosal irritation. Pediatric tissue absorbs these irritants far more rapidly than adult skin, explaining why children developed severe welts within hours of touching contaminated surfaces while adult staff experienced milder secondary symptoms.
