Bromacil is an organic

citrus fruit and pineapple.[3]
Bromacil is also found to be excellent at controlling perennial grasses.

Safety

There are quite a few safety precautions that should be taken when dealing with Bromacil. Dry formulations containing bromacil must bear the word "Caution" and liquid formulas must signal "Warning."

dermal, and inhalation routes and has been placed in Toxicity Category IV (the lowest of four categories) for these effects.[2]
This herbicide should be stored in a cool, dry place and after any handling a thorough hand-washing is advised.

In regards to occupational exposure, the National Institute for Occupational Safety and Health has recommended workers handing bromacil not exceed an exposure of 1 ppm (10 mg/m3) over an eight-hour time-weighted average.[6]

Facts

Bromacil (40%) is combined with the active ingredient

U.S. Environmental Protection Agency (EPA) assessed risk to workers using several major exposure scenarios. Bromacil is stable to hydrolysis under normal environmental conditions.[2]

Applications

Bromacil is applied mainly by sprayers including boom, hand-held,
