For the weeds that keep coming back
A selective, post-emergent herbicide built for the hard-to-kill weeds, like Guildford grass (onion grass) and onion weed, that shrug off most other sprays.
- Targets persistent weeds: onion grass, onion weed, bindii, clover, oxalis and more
- Selectively removes ryegrass from Couch, Buffalo and Kikuyu lawns
- Low odour, low toxicity, water-dispersible granule that mixes clean
- Listed safe on Couch, Buffalo and Kikuyu, but not Queensland Blue Couch. Check the label for your grass type, or spot-test first if you are unsure
Spray it in three steps
Mix the granules at the label rate into water in your sprayer until fully dissolved.
Spray evenly across the weeds and the area while they are actively growing, ideally with daily temps of 18 to 21°C or higher. Pick a rain-free window.
Give it time to work, and follow up per the label if any weeds remain. Avoid mowing just before or just after.

| Rate | Per label |

| Temperature | 18 to 21°C+ |
Mix at the label rate, in a rain-free window. Avoid spraying in cold winter periods when daytime temps stay below 15°C, as it works less well. One 50g pack treats a good run of lawn, see the label for your weeds.
