How to kill parkinsonia
Parkinsonia is a weed of national significance and is identified as being invasive, having the potential for widespread environmental, social and economical damage. Landowners and land managers at all levels are responsible for actively managing this weed.
The best time to treat for control of parkinsonia is from September through to May as a basal bark or cut stump application with Access, although if conditions allow this treatment can be used year round.
Recommended treatment rate with Access is 1:60 with diesel or Biosafe.
