Biosecurity Queensland undertakes biological weed control research in Queensland.
Strict measures are in place to ensure that these agents do not negatively affect native plants and animals or horticultural and agricultural crops.
Biosecurity Queensland's biological control group is presently working on eight weeds of concern to Queensland:
- cat's claw creeper
- giant rat's tail grass
- madeira vine
- mother of millions
- prickly acacia
- parthenium weed
- Siam weed
A number of biological controls have been released at strategic infestation sites, and are spreading to other infestations of their host weed.
Biological control agents can reduce the vigour, size and competitiveness of weed infestations; however, they rarely get rid of weeds altogether. Biological control works best in conjunction with other control methods.
