Paspalum Control Guide

Do's

  • Plan your control program, this will save time and money in the long-run;
  • Consider the impact of your control methods on off-target species, especially if herbicides are used;
  • Ensure machinery and equipment is washed down between sites or prior to contractors leaving site;
  • Get in early - for new infestations, eradicate before the plants reach the flowering stage: once plants begin seeding, control becomes more difficult and expensive;
  • Carefully time your use of herbicide for best results (see the page Herbicides for Paspalum Control for more information);
  • Coordinate your control program with neighbouring landholders where your weed problem crosses property boundaries;
  • Revisit and regularly inspect the site and ensure follow-up is undertaken;
  • Use a combination of different control methods; and
  • Establish vigorous pasture (or native species) after removal to reduce re-infestation.

Don'ts

  • Don't introduce paspalum to paspalum-free areas (e.g. by failing to wash down machinery and equipment between sites);
  • Don't start your control program without first planning your approach;
  • Don't allow paspalum to flower and set seed before treatment;
  • Don't rely on one attempt at removal - follow-up is essential;
  • Don't rely on just one control method.


Spread of paspalum

  • Paspalum spreads by seed. The seed is sticky and is readily transported on shoes, clothing and machinery.
  • Paspalum can readily spread form roadsides into adjacent orchards.


Avoid the introduction of paspalum

  • Hygiene practices involving the thorough cleaning of machinery and footwear after working in paspalum infested areas is critical to minimise spread.
  • See the Washdown Guidelines for Weed and Disease Control for detailed information on how to wash-down equipment and personnel to reduce the chance of spreading paspalum.


Physical removal

  • Paspalum can be removed by hand; use a mattock to remove all of the crown and prevent regrowth where plants are well established.
  • Mowing and slashing will remove flowering heads but will not provide control of established plants. Seed may be spread by mowing and slashing implements.
  • In turf, resow with desirable grass species after the removal of the paspalum.


Cultivation

  • Cultivation can be used to control paspalum; ensure that the paspalum clumps are thoroughly broken up, leaving the small fragments to dry out on the soil surface.


Chemical control

  • A number of herbicides are registered for use on paspalum in Tasmania. See Herbicides for Paspalum Control for more information.
  • Paspalum should be treated when actively growing (late spring to early autumn).
  • Repeat herbicide application may be required for well established plants.
