Where It Comes From
Agricultural use on dicamba‑tolerant soybeans/cotton and other crops; turf and rights‑of‑way. Can reach air via spray/vapor drift and water via runoff [1][2].
How You Are Exposed
Mixing, loading, or applying products; being near treated fields during or soon after spraying; touching treated plants/soil; contaminated water; residues on food (generally low and regulated) [1][2].
Why It Matters
Short‑term exposure may cause eye/skin irritation, coughing, and nausea; swallowing large amounts can cause vomiting. EPA classifies dicamba as not likely to be carcinogenic to humans [1][3].
Who Is at Risk
Applicators and farmworkers; people living near treated fields; children and pets on treated lawns; those with asthma or other breathing problems [1][3].
How to Lower Your Exposure
Follow label directions and wear proper protective gear if applying; avoid treated areas until sprays dry and re‑entry times pass; close windows and bring items indoors during nearby spraying; rinse produce under running water; report drift incidents to your state pesticide agency [1][3].
