Picloram

Type: Herbicide

Mode of Action: Mimicking the plant hormone auxin

Common Product Names: Tordon & Pathway

What is it?

Picloram is a systemic herbicide widely used for controlling broadleaf weeds and woody plants. It is particularly effective against perennial species that are difficult to manage with other herbicides. Picloram is absorbed by the foliage and roots of plants, and it translocates throughout the plant, ensuring comprehensive weed control. Commonly use in cut stump treatments and for brush control.

How does it work?

Picloram is applied to the foliage or soil and then absorbed by the plant. Once inside, it moves throughout the plant's vascular system. By mimicking the plant hormone auxin, Picloram causes the cells to grow uncontrollably. This abnormal growth disrupts vital functions, ultimately leading to the plant's death.

Benefits

  • Residual Activity: Picloram has a long residual activity, meaning it remains active in the soil for extended periods, providing ongoing weed control.
  • Post-Emergent Application: Ideal for post-emergent applications, Picloram targets weeds that are already growing.
  • Systemic Action: Translocates within the plant, ensuring thorough weed elimination.
