Mimosa diplotricha

Preferred Scientific Name: Mimosa diplotricha

Commonly known as Creeping sensitive plant, the plant grows in large clumps which are hard to remove due to the plant's thorns.

Why is it a problem?

Mimosa diplotricha reduces crop yields and pasture production. It forms impenetrable thickets that smother native plants and crops. If present in crop fields during harvesting it jams farm machinery, while the thorns injure people.

Impacts

  • Severe crop reduction
  • Damages farm machinery
  • Loss of land
  • Reduces native biodiversity
  • Negatively impacts livelihoods

What’s the solution?

Prevention

Giant sensitive plant is listed as a noxious weed in countries such as Australia and the USA, meaning that if it is found, it must be declared and then eradicated before it becomes unmanageable. 

Chemical control

Chemical control has been indicated as an option for managing Giant sensitive plant. Spraying infestation regrowth and post mechanical control after a rain has proven to be an effective method of preventing full regrowth. 

Biological control 

The psyllid Heteropsylla spinulosahas has been found to stunt the plant and supresses seed production by up to 88%. The psyllid has successfully established across many countries in Asia, such as Papua New Guinea.
