Q1: What is Cornerstone Plus weed killer, and why is it used?
A1: Cornerstone Plus is a concentrated agricultural herbicide manufactured for non-selective weed control. It contains 41% glyphosate as its active ingredient alongside industrial surfactants that dissolve plant leaf waxes to ensure chemical uptake. It kills any vegetation it contacts.
Q2: What acute health symptoms occur from touching or inhaling this herbicide?
A2: Immediate symptoms stem primarily from surfactant toxicity and acute chemical contact. Affected individuals develop contact dermatitis, bright red rashes, skin blistering, burning or itchy eyes, nasal inflammation, and nausea. Prolonged inhalation of spray drift can induce coughs and upper respiratory tightness.
Q3: Does California law allow school districts to spray glyphosate-based products?
A3: While not outright banned by state statute, herbicide use on campuses is strictly regulated by the California Healthy Schools Act. School districts must implement an Integrated Pest Management plan, provide 72 hours of written notice to staff and parents, post physical warning placards around the treatment perimeter, and keep individuals away until surfaces have dried thoroughly.
Q4: How should parents respond if their child touches freshly sprayed herbicide?
A4: Remove all exposed clothing immediately and wash it separately. Flush contaminated skin with copious amounts of lukewarm water and mild, fragrance-free soap for at least 15 minutes without rubbing abrasively. If chemical exposure symptoms like rashes, hives, eye swelling, or breathing difficulties develop, seek immediate emergency medical care and inform doctors of the specific chemical exposure.
