Management

Small infestations can be cleared by hand, ensuring that all parts of the plant, including the roots, are removed and incinerated or buried deeply. Attempts to clear sites mechanically should be carried out with caution in order not to spread fragments of the plant down stream or to contaminate machinery.

Bury deeply underground away from watercourses.

Glyphosate herbicide (mixed at the rate of 2 litres/100 litres water plus Penetrant) provides good control, however the timing of application appears critical eg spring is the best time for control.
