Sulfometuron methyl (SFM)

Type: Herbicide

Mode of Action: Inhibiting the enzyme acetolactate synthase (ALS)

Common Product Names: Oust XP, SFM, Spyder

What is it?

Sulfometuron methyl is a selective, systemic herbicide used to manage a wide range of annual and perennial grasses and broadleaf weeds. It is commonly used in non-crop areas such as industrial sites, railroads, and rights-of-way, as well as in forestry and conifer release applications. The chemical structure of sulfometuron methyl allows it to be absorbed through both the foliage and roots of plants, ensuring comprehensive weed control.

How does it work?

Sulfometuron methyl works by being absorbed into the plant tissue, primarily through the leaves and roots. Once inside, it targets and inhibits the enzyme acetolactate synthase (ALS). This enzyme is crucial for the biosynthesis of the branched-chain amino acids, which are vital for protein synthesis and plant growth. By blocking ALS, sulfometuron methyl disrupts protein synthesis, leading to halted cell growth and eventual plant death. This mode of action is particularly effective against a wide range of grasses and broadleaf weeds.

Benefits

  • Systemic Action: The herbicide is absorbed through both foliage and roots, ensuring that the entire plant, including the root system, is affected.
  • Long Residual Activity: Sulfometuron methyl provides long-lasting control, reducing the frequency of reapplication and ensuring sustained weed management.
