Thiencarbazone-methyl

Type: Herbicide

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

Common Product Names: Derigo & Capreno

What is it?

Thiencarbazone-methyl is a selective, systemic herbicide known for its effectiveness in controlling a broad spectrum of weed species. It is primarily used in cereal crops such as wheat and barley, offering pre-emergent and post-emergent weed control. The chemical is valued for its ability to be integrated into herbicide resistance management programs, providing a reliable solution to farmers facing challenges with resistant weed populations.

How does it work?

Thiencarbazone-methyl works by being absorbed through the leaves and roots of target plants. Once inside the plant, it inhibits the ALS enzyme, which is crucial for the synthesis of the amino acids valine, leucine, and isoleucine. The inhibition of ALS leads to a shortage of these essential amino acids, halting protein synthesis and plant growth. As a result, the affected weeds stop growing and eventually die.

Benefits

  • Flexible Application: It offers both pre-emergent and post-emergent application options, providing flexibility in weed management practices.
  • Selective Herbicide: It targets weeds while leaving the desirable plants relatively unharmed, making it ideal for use in turf and crop management.
  • Low Application Rates: Due to its potency, lower application rates are required, which can reduce the amount of chemical used and potentially lessen environmental impact.
  • Systemic Action: Its systemic nature ensures that the herbicide is transported throughout the plant, ensuring thorough control of the targeted weeds.
