Bromoxynil octanoate

PesticidesDevelopmental_Toxicity

Bromoxynil octanoate is a selective herbicide used to kill broadleaf weeds in crops like cereals and corn, and on turf. It is toxic, especially with skin contact or inhaling spray mist, and breaks down to bromoxynil in the body and environment [1][2].

Where It Comes From

Agricultural and turf herbicide products; field spraying and mixing/loading; residues on treated crops; drift and runoff near fields [1][2].

How You Are Exposed

Breathing spray/drift, skin contact with treated plants or equipment, eating residues on food, or drinking contaminated well/surface water near treated areas [1][2].

Why It Matters

Short-term exposure can irritate eyes/skin and cause nausea or headache; repeated higher exposures have affected the liver and thyroid and caused developmental effects in animal studies [1][2].

Who Is at Risk

Pesticide applicators and field workers; people living or working near treated fields; pregnant people and young children; pets on recently treated lawns [1][2].

How to Lower Your Exposure

Follow label directions and wear protective gear; respect re-entry intervals; keep children/pets off treated areas until dry; close windows during nearby spraying; wash/rinse produce; test private well water near agriculture [1][2].
