Reducing the spread of Serrated Tussock: A few tips

Preventing serrated tussock from establishing on your property is the best method of control. Land holders with seeding serrated tussock should also make reasonable efforts to reduce seed spread to neighbouring areas.

As serrated tussock is readily spread by wind across paddock boundaries and to a lesser extent, spread by vehicles, machinery, stock, people and water, it is important to have procedures in place that will help reduce its spread.

General property hygiene procedures will reduce serrated tussock, and other weeds, from entering or leaving a property.

Useful strategies to reduce spread include:

  • learn to correctly identify serrated tussock.
  • identify high risk areas of spread onto and within the property and regularly monitor these areas. For example, fence lines, stock yards and holding paddocks.
  • control serrated tussock as soon as it is found.
  • consider using vendor declarations for buying and selling stock feed, or anything that could be contaminated with seed.
  • do not harvest pasture, grain or fodder crops while serrated tussock is in seed.
  • do not allow contractors on site unless they are clean and free from serrated tussock seed.
  • consider using contractors who have a history of being weed-aware.

In all situations, make it a priority to control serrated tussock before flowering. If flowering, or seed-set, has occurred, use the following to help reduce further spread.

Avoid working in infested areas until serrated tussock has been controlled. Minimise movement into and out of infested areas when serrated tussock is in seed. Stay on formed tracks and roads. Plan to work in clean areas first.

Stock

Stock can spread serrated tussock by:

  • transporting seed attached to the coat or by mud in the animals hooves
  • eating the plant while in seed, then excreting viable seed.

Stock can be an important source of serrated tussock weed spread and reducing all risks is important.

  • limit the movement of stock from serrated tussock infested areas to clean areas.
  • remove stock from infested paddocks before serrated tussock goes to seed. Note: serrated tussock should not be allowed to seed!
  • place stock in quarantine/holding paddocks if:
    • stock are suspected to be contaminated with seed
    • new stock are entering the property and suspected of being contaminated with weed seed.

If suspected of eating serrated tussock seed, quarantine stock for at least 10 days and provide with clean feed and water. Always use the same holding paddock, monitor for serrated tussock seedlings and control when required.
