Bromoxynil
Type: Herbicide
Mode of Action: Inhibiting photosynthesis
Common Product Names: Cleansweep
What is it?
Bromoxynil is primarily a contact herbicide with an effective post-emergent action, meaning it is applied after the targeted weeds have emerged from the soil. It is known for its selective control of broadleaf weeds while typically leaving grasses unaffected. Bromoxynil is often used in combination with other herbicides to broaden the spectrum of weed control and to reduce the chances of weed resistance. It is often used in cereal crops like corn, wheat, and barley.
How does it work?
When applied, Bromoxynil is absorbed primarily through the leaves of the weeds. It then travels to the chloroplasts, where it interferes with the electron transport chain in the photosystem II complex. Bromoxynil acts by inhibiting the photosynthetic process in susceptible plants. This disruption leads to the production of reactive oxygen species, which causes cell membrane damage and leads to the death of the weed. The visible effects of Bromoxynil on weeds can usually be observed within a few days to a week after application, depending on environmental conditions.
