Why Spartan

Stop weeds before they ever appear

Spartan is a selective pre-emergent. It forms a barrier that stops weed seeds establishing, so you prevent the weeds rather than spraying them once they are already up.

  • Prodiamine at 480g/L, a proven pre-emergent active
  • Targets Winter Grass (Poa annua), Summer Grass and crowsfoot
  • Works on the root tips of newly germinated weeds
  • 500ml covers roughly 1,250m² of lawn
How to use

Three steps to a weed barrier

1
Measure and mix

Work out your area, then mix Spartan into water in your sprayer at 30 to 40ml per 100m².

2
Spray evenly

Cover the whole area in one even pass so the barrier is consistent.

3
Water in

Water it in with at least 6mm, ideally straight after spraying. It can sit for up to a week before watering, but the sun starts to break it down, so sooner is better.

Timing: apply before weeds germinateAutumn for winter weedsLate winter to early spring for summer weeds

Questions

Good to know

What does a pre-emergent actually do?+
It stops weed seeds from establishing. Spartan forms a barrier in the soil and acts on the root tips of newly germinated weeds, so they cannot get going. It prevents weeds rather than killing ones already there.
When should I apply it?+
Before the weeds germinate. Apply in autumn to prevent Winter Grass and other winter weeds, and in late winter to early spring to prevent summer weeds. The barrier needs to be down before the seeds wake up.
Do I need to water it in?+
Yes. A pre-emergent has to be watered in after spraying so it settles into the soil and forms the weed barrier. Without watering in, it will not work properly. Use at least 6mm, ideally straight after spraying. It can sit for up to a week, but the sun starts to break it down, so sooner is better. Do not water to the point of runoff in the first 3 days.
Is it safe for my lawn?+
Spartan is a selective pre-emergent for a wide range of established lawns, not just warm-season turf. Turf tolerance and rates vary by grass type and situation, so always check the label for your grass type before you apply, and follow the rate it gives. Do not apply if you are overseeding, or to newly seeded or newly laid turf. Wait until the lawn has full cover and roots deeper than 3cm. Do not spray a stressed lawn or waterlogged soil, or when heavy rain is forecast within 48 hours.
Will it kill weeds I can already see?+
No. Spartan does not control weeds that are already up. For weeds already growing, knock them down first with something like Bow & Arrow, then use Spartan to stop the next lot coming through.
How much area does it cover?+
A 500ml bottle treats roughly 1,250m² of lawn, so a little goes a long way. That is at 40ml per 100m². The rate is 30 to 40ml per 100m².

Stop the weeds before they start

Lay the barrier down at the right time and prevent the weeds instead of chasing them all season. One 500ml bottle covers about 1,250m².
