Onset 10 GR is a premium granular pre-emergent herbicide designed to protect established turf from the germination of grass weeds.

Formulated with Prodiamine (10 g/kg), it creates a protective barrier in the soil that prevents weed seeds from establishing, helping maintain a clean and healthy lawn.

Onset 10 GR can provide residual weed control for up to six months, reducing the need for repeated treatments and lowering reliance on post-emergent herbicides.

It is highly effective against a broad range of common turf weeds including Summer grass (crabgrass), Crowsfoot grass, Parramatta grass, Rat’s tail fescue, African lovegrass, Winter Grass, and Paspalum species.

Ideal for turf managers and homeowners looking for long-lasting, preventative weed control while supporting stronger, more resilient turf.

The product uses a uniform, dust-free 200 SGN granule (~2 mm) to ensure even coverage and consistent distribution when applied with a spreader. This makes application simple and accurate while minimising drift.

Beyond weed control, Onset 10 GR also:

• Supports overall turf health – contains ~26% plant-available silicon plus trace elements like calcium, magnesium, iron, copper, zinc, and molybdenum.
• Strengthens plant cell walls for a more resilient lawn.
• Enhances nutrient uptake to boost growth and colour.
• Increases tolerance to stress, wear, and environmental pressures, helping turf stay strong under challenging conditions.

Safe for use on a wide range of established turf varieties, including buffalo, couch (common and hybrid), kikuyu, zoysia, seashore paspalum, bahia and carpetgrass. Its non-scheduled chemistry also makes it suitable for use in residential lawns, sports fields and other public or high-traffic turf areas.

Granular Ease of Use. Convenient granule formulation allows simple broadcast application- no tank mixing required.
