Slashing reduces the height and seed production of serrated tussock plants using a mower or slasher or similar tool. Slash before the weed flowers and reduce its height to just above ground level. Regularly clean machinery to prevent further spread. Slash weed-free areas first and train operators in machinery hygiene and identifying serrated tussock. Slasher covers and mower blowers may reduce the spread of seed.
When
Slash in late winter to early spring to prevent seed head production and to prepare for crops or pasture. Avoid slashing when serrated tussock is in seed.
Pros and cons
Slashing may limit seed production if conducted at the right time of year. It can reduce fire risk and limit soil disturbance. However, slashing doesn’t kill the plant and can stimulate serrated tussock growth. It may increase the spread of seed without precautions such as machinery hygiene.
Follow up
Regular mowing and slashing to maintain low serrated tussock growth. Control plants with other suitable techniques.
