Description:
Diquat dibromide is a non-selective contact herbicide that produces desiccation and defoliation. When acting as a herbicide, diquat inhibits photosynthesis (electron transport). In light-exposed plants, it accepts an electron from photosystem I (more specifically ferredoxin), to form its green radical cation. The electron is then transferred to molecular oxygen, producing destructive reactive oxygen species. This compound can be used as a reference compound for analytical studies.
