Imazapyr is an insoluble herbicide which belongs to the imidazolinone family.
| Mechanism of Action | Imazapyr inhibits acetolactate synthase (ALS) which plays an essential role in the biosynthesis of branched chain amino acids. |
| Plant Biology Applications | Imazapyr is most effective post-emergence to kill broadleaf weeds and grasses less than 10 cm in height (Armel, 2003). ALS inhibiting herbicides account for approximately 17.5% of the global herbicide usage in corn and other agricultural goods (Green, 2008). |
| Molecular Formula | C13H15N3O3 |
