A great lawn starts with prevention. Onset 10 GR is a high-performance granular pre-emergent herbicide designed to protect established turf by stopping troublesome grassy weeds before they germinate.
Rather than waiting for weeds to appear and trying to control them after they have established, Onset 10 GR creates a preventative barrier that helps reduce new weed growth, keeping lawns cleaner, healthier, and easier to maintain.
Grassy weeds such as summer grass, crowsfoot grass, wintergrass, paspalum, and other invasive species can quickly impact the appearance, density, and performance of quality turf.
Once established, these weeds can be difficult to remove without affecting the surrounding lawn. Onset 10 GR works at the germination stage, helping stop weeds before they become a problem.
With up to 6 months of residual pre-emergent weed germination control when properly activated, Onset 10 GR provides long-lasting protection and helps reduce the ongoing pressure of unwanted grassy weeds.
Onset 10 GR provides pre-emergent control of a broad range of troublesome grassy weeds, including:
✔ Summer Grass (Crabgrass)
✔ Crowsfoot Grass (Eleusine indica)
✔ Parramatta Grass
✔ Rats Tail Fescue
✔ African Love Grass
✔ Wintergrass
✔ Paspalum species
By preventing these weeds from establishing, Onset 10 GR helps maintain a cleaner, more consistent turf surface throughout the growing season.
Onset 10 GR is suitable for use on many established turf varieties, including:
✔ Buffalo
✔ Couch (Common and Hybrid)
✔ Kikuyu
✔ Zoysia
✔ Seashore Paspalum
✔ Bahia Grass
✔ Carpetgrass
This makes it a versatile choice for residential lawns, commercial turf areas, sports surfaces, and high-use landscapes.
As a granular pre-emergent herbicide, Onset 10 GR is applied to the turf surface and activated according to label directions. Once activated, it forms a protective zone in the soil that targets weed seeds as they begin to germinate.
The key to successful pre-emergent control is timing — applying before weed seeds emerge allows Onset 10 GR to work preventatively rather than trying to control mature weeds after they appear.
For best results:
Apply before expected weed germination periods
Ensure correct activation according to label instructions
Apply evenly across the treatment area
Maintain healthy turf practices to maximise lawn performance
Onset 10 GR features a uniform, dust-free 200 SGN granule (approximately 2 mm) designed for consistent spreading and minimal drift.
The even granule size helps provide:
Reliable application coverage
Reduced dust during handling
Improved user experience
Consistent product distribution across the lawn
Beyond weed prevention, Onset 10 GR contains approximately 26% plant-available silicon, along with beneficial trace elements including:
Calcium (Ca)
Magnesium (Mg)
Iron (Fe)
Copper (Cu)
Zinc (Zn)
Molybdenum (Mo)
Silicon helps support stronger turf by contributing to improved plant structure, helping strengthen cell walls, support nutrient uptake, and improve tolerance to environmental stress and wear.
This makes Onset 10 GR more than just a pre-emergent — it is a preventative turf management tool designed to support stronger, more resilient lawns.
With non-scheduled chemistry, Onset 10 GR provides a practical option for use in a range of managed turf environments where ease of handling and responsible application are important.
Perfect for:
Home lawns
Commercial landscapes
Public open spaces
High-traffic turf areas
Professional turf maintenance programs
Don’t wait until grassy weeds take over. Onset 10 GR provides long-lasting pre-emergent protection combined with turf-strengthening silicon technology to help maintain a healthier, cleaner, more resilient lawn.
Protect your turf from the start with Onset 10 GR — proactive weed prevention for premium lawns.
