Mimosa (Terestrial)

Mimosa (Mimosa pigra) is a large, upright, prickly shrub that can grow up to 6 meters tall. It forms dense, impenetrable thickets, primarily in floodplains, riverbanks, and wetlands, but also in disturbed sites like roadsides and grazing lands. The plant is native to tropical America and was introduced to Australia in the late 1800s as an ornamental plant.

Methods of Control

Mechanical Control:

• Hand-pulling or using machinery to remove plants. Follow-up treatment is necessary to manage regrowth.

Chemical Control:

• Fluroxypyr: Effective for foliar, basal bark, and cut stump applications.
  
• Glyphosate: Used in stem injection and cut stump methods.
  
• Metsulfuron-methyl: Applied via aerial control with a non-ionic wetting agent.
  
• Dicamba: Used for both foliar and aerial applications.

Biological Control:

• Several biological control agents have been released, with varying success.

Integrated Management:

• Combining mechanical, chemical, and biological methods for effective long-term control.
