  • Cut-leaf nightshade spreads by seed. The seed viability of cut-leaf nightshade is not certain, but some research indicates that it can remain viable in the soil for around nine years.
  • Rooting from the nodes results in some local spread of the plant.
  • Although toxic, animals are known to spread the seed.
  • Cut-leaf nightshade can be spread by machinery, vehicles and contaminated material such as soil and sand.

Avoid the introduction of cut-leaf nightshade

  • Dispose of removed material carefully to avoid new plants germinating.
  • Ensure all vehicles and machinery that have been in a cut-leaf nightshade infested area are thoroughly cleaned down before moving to a clean area.
  • See the Washdown Guidelines for Weed and Disease Control for detailed information on how to wash-down equipment and personnel to reduce the chance of spreading cut-leaf nightshade.

Physical removal

  • Individual plants can be dug out. Ensure any fruiting plants are bagged and deep buried on site.

Chemical control

  • Under an off-label permit issued by the Australian Pesticides and Veterinary Medicines Authority (APVMA), there are herbicides registered for the control of cut-leaf nightshade in Tasmania. See Herbicides for Cut-leaf Nightshade Control for more information.
