Identification
Common NameImazaquin
ClassSmall Molecule
DescriptionImazaquin is primarily used as a herbicide to control weed growth on lawns and turf fields. Due to the fact that it is highly effective and selective, it is one of the most commonly used herbicides.It is classified as an imidazolinone herbicide Imazaquin inhibits the acetohydroxy acid synthase (AHAS) enzyme which is responsible for the synthesis of the branched chain amino acids valine, leucine, and isoleucine. When applied, imazaquin halts weed growth which eventually kills the weed or causes the weed to die due to its incapability to compete with surrounding vegetation.
