Redistributing the Crofton weed rust fungus to a new site:

It is your responsibility to meet the terms of any weed control compliance order imposed by the relevant authority on the site selected for a biological control release. If applicable please check with the relevant authority to ensure that you have permission to quarantine from other control programs the area where the Crofton weed rust fungus will be released.

A biological control release cannot be used as an excuse not to control Crofton weed or other weeds on the rest of the property. There is no guarantee that the rust fungus will establish and have an impact at your release site, as epidemics are regulated by prevailing environmental conditions.

Biological control is not a ‘silver bullet’ but rather a long-term strategy with potential to complement existing control techniques.
