Weed Control: Parkinsonia

DI-BAK-Parkinsonia-logo

BHA is the first company in Australia to commercialise a proven,  naturally-occurring bioherbicide (Di-Bak Parkinsonia) for the control of  Parkinsonia aculeata, a Weed of National Significance (WoNS).

     

 Di-Bak Parkinsonia
  • works by inducing dieback, a disease of trees and shrubs characterized by death of the young shoots, which spreads to the larger branches. Dieback is naturally caused by injury to the roots, climatic conditions or attack by bacteria or fungi
  • has been developed in Australia for unique Australian conditions. It is environmentally-sound, safe to handle, non-toxic and harmless to native vegetation, animals, and humans.
  • it consists of three pathogenic fungal isolates that induce the dieback disorder in Parkinsonia trees, triggering a long term epidemic which weakens the tree population and reduces seedling rates.
BHA is commercialising 8 years of research on Di-Bak Parkinsonia undertaken by the University of Queensland and is currently undertaking trials on other bioherbicide products targeting some of Australia’s other greatest weed threats.
