Bromoxynil

Bromoxynil is a nitrile herbicide, trade names include Brominal, Bromotril, Bronate, Buctril, Certrol B, Litarol, M&B 10064, Merit, Pardner, Sabre, and Torch. It is used for post-emergent control of annual broadleaf weeds. It is especially effective in the control of weeds in cereal, corn, sorghum, onions, flax, mint, turf, and on non-cropland. It works by inhibiting photosynthesis. Lethal doses in mammals range between 60 and 600 milligrams ingested per kilogram of body weight, and teratogenic effects have been observed in rats and rabbits above 30 milligrams per kilogram. Chronic exposure for more than one year in humans caused symptoms of weight loss, fever, vomiting, headache, and urinary problems in one documented case. In the United States it is distributed as a restricted use pesticide in toxicity class II (moderately toxic) and not available for homeowner use.
