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