Now is the time to control tussock before seeding

Preventing serrated tussock from establishing on your property is the best method of control and is best done in Spring prior to seeding. The Victorian Serrated Tussock Working Party (VSTWP) is asking landholders with seeding serrated tussock to make reasonable efforts to reduce seed spread to neighbouring areas, as serrated tussock seeds late spring.

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.

Community Engagement Officer with the VSTWP said ‘in all situations, make it a priority to control serrated tussock before flowering. If flowering, or seed-set, has occurred, avoid working in infested areas until serrated tussock has been controlled’. Stock can spread serrated tussock by transporting seed attached to the coat or by mud in the animals hooves or by eating the plant while in seed, then excreting viable seed” noted Mr Carter.

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. Spring is the perfect time to get your serrated tussock under control prior to it seeding in late spring and early summer.

“It’s believed serrated tussock now covers more than 250,000 hectares of land in Victoria. Large infestations require ongoing management and the integration of a number of control techniques to prevent seeding and further spread across the landscape’ said Ivan Carter.
