Where It Comes From
Sprayed or spread as granules on crops (e.g., corn, soybeans, vegetables), turf, and rights‑of‑way; it binds to soil and can run off into surface water [1][2].
How You Are Exposed
Touching treated lawns/soil, breathing spray mist or dust during/after application, eating residues on produce, and occasionally through drinking water near use areas [1][2].
Why It Matters
Can irritate skin and eyes; high-dose animal studies show liver and thyroid effects. EPA has not identified cancer or noncancer risks of concern for the general public when products are used as labeled. Highly toxic to fish and aquatic invertebrates [1][2].
Who Is at Risk
Pesticide applicators and farmworkers; people living near treated fields; children and pets on recently treated lawns [1][2].
How to Lower Your Exposure
Follow label directions and reentry times; keep kids/pets off treated areas until dry and after posted intervals; wash hands and rinse/peel produce; remove shoes after yard work; applicators should use protective gear and avoid drift [1][2].
