Thiram

Potential EDCPesticidesMutagenTeratogen

Thiram is a pesticide (fungicide) used to protect seeds, crops, and turf from mold and rot. It can irritate skin and eyes and, at higher doses, affect the nervous system, so limiting exposure matters [1][2].

Where It Comes From

Seed treatments, orchards, ornamentals, turf/golf courses; sometimes as a wildlife/animal repellent and in rubber manufacturing [2][3].

How You Are Exposed

Mixing/applying products; touching treated plants or soil; spray drift from nearby applications; residues on food; dust or water near farms [1][2].

Why It Matters

Can cause skin/eye irritation, headache, nausea, or dizziness; repeated/high exposure may affect nerves or trigger allergic skin reactions. Animal studies show reproductive/developmental effects. EPA has not classified it as a human carcinogen [1][2][3].

Who Is at Risk

Farmworkers, applicators, seed‑treatment and turf workers; people living near treated fields; pregnant people and young children [1][2].

How to Lower Your Exposure

Follow label directions; wear chemical‑resistant gloves and eye/skin protection when handling; keep kids/pets off treated areas until dry; wash hands, work clothes, and produce; consider certified water filters if pesticides are a local concern [1][2][3].
