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.

Why Use Onset 10 GR?

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.

Broad-Spectrum Grassy Weed Protection

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.

Safe for a Wide Range of Established Turf Types

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.

How Does Onset 10 GR Work?

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

Advanced Granule Technology for Accurate Application

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

Added Turf Health Benefits with Plant-Available Silicon

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.

Ideal for High-Traffic and Public Areas

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

Prevent Weeds Before They Start

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.

Surefire Tempra 750 WG – Effective Weed Control in a Convenient Water-Dispersible Granule Form

Surefire Tempra 750 WG is a high-quality herbicide formulated to provide reliable weed management for agricultural and horticultural applications. Targeted weeds include Nutgrass and Mullumbimby couch.

With its convenient water-dispersible granule (WG) formulation, it is easy to measure, mix, and apply, helping growers achieve consistent results when used according to the registered label directions.

Designed for professional growers and agricultural users, Surefire Tempra 750 WG delivers targeted weed control and helps support cleaner crops and improved paddock management. Its practical formulation provides excellent handling characteristics, making it a valuable addition to an integrated weed management program.

Take Control of Stubborn Nutgrass with Tempra

Nutgrass is one of the toughest weeds to eliminate from lawns and gardens. Unlike ordinary grass weeds, nutgrass is a sedge that survives through an extensive underground system of roots and nut-like tubers, allowing it to quickly return even after the leaves have been removed.

Tempra provides targeted nutgrass control by working through the plant’s foliage and moving towards the underground growth points. When applied correctly, it helps reduce existing infestations and provides a practical solution for managing this persistent weed.

Why Nutgrass Is So Difficult to Control

Nutgrass can be frustrating because the visible weed is only part of the problem. Underground tubers store energy and can produce new growth long after the foliage has been treated. This is why pulling, mowing, or simply removing the leaves often results in regrowth.

Successful control requires a treatment that can be absorbed by the plant and reach the areas where nutgrass stores its energy.

Get Better Results with a Surfactant

For improved performance, use Tempra with a suitable surfactant (wetting agent) where permitted by the product label.

Nutgrass leaves can be narrow and difficult to wet, so a quality surfactant helps the spray solution:

• Spread more evenly across the leaf surface

• Improve coverage of the foliage

• Enhance contact between the herbicide and the plant

Better coverage means more opportunity for Tempra to be absorbed and transported through the plant.

https://www.lawndoctor.com.au/shop/p/reactor-wetter-600

Application Tips for Best Results

✔ Apply when nutgrass is actively growing and has healthy green foliage
✔ Avoid treating drought-stressed or damaged plants
✔ Allow enough leaf growth before spraying so the plant can absorb the treatment
✔ Apply with thorough coverage for maximum effectiveness
✔ Allow time for results — nutgrass control occurs as the herbicide works through the plant system
✔ Repeat applications may be required for established infestations

Zoysia Australis is one of Perth's most exciting recent turf arrivals — a fine-leaved zoysia variety bred specifically for Australian conditions and available exclusively through Lawn Doctor in Western Australia.

Where most lawn varieties force a trade-off between water efficiency and appearance, Zoysia Australis delivers both. Its deep root system and excellent water use efficiency allow it to maintain colour and density through Perth summers on standard two-day restrictions, while its fine, dense growth habit produces a consistently attractive surface with minimal intervention.

Zoysia Australis is the most naturally weed-resistant variety we grow. Once established, its tight horizontal growth leaves little space for weed seeds to germinate, significantly reducing the herbicide inputs needed to maintain a clean lawn.

Its slower growth rate compared to couch varieties is often seen as a disadvantage but is actually one of its most practical benefits — fewer mowing sessions, less clipping volume and a lawn that holds a consistent appearance for longer between cuts.

Key characteristics:

• Exceptional drought tolerance and water use efficiency

• Naturally weed-resistant due to dense, tight growth habit

• Lower mowing frequency than couch or buffalo varieties

• Outstanding salt and coastal exposure tolerance

• Good shade tolerance — suitable for sites with 4+ hours of direct sun

• AusGAP certified for genetic purity

• Grown at our Gingin turf farm and cut fresh to order

Applerich Liquid Goodies is a 3-in-1 hose-on product combining a soil wetting agent, humic acid and kelp extract in a single easy application. It is designed for Perth's sandy, hydrophobic soils and addresses three of the most common lawn health issues at once — poor water penetration, low organic matter and nutrient uptake inefficiency.

The 2L hose-on format is the most convenient delivery method available — attach directly to your garden hose, apply across the lawn and water in. No mixing, no sprayer required. Covers up to 200m² per bottle.

The wetting agent component restores soil moisture penetration in hydrophobic areas. Humic acid improves soil structure and cation exchange capacity, increasing the soil's ability to hold nutrients. Kelp provides natural growth stimulants and trace elements that support root development and stress resistance.

Use Liquid Goodies every 6 to 8 weeks through the growing season as a soil health maintenance product, or as a rapid response treatment for visible dry patch or hydrophobic areas.

ESTATE® Herbicide is Syngenta’s powerful combination of three active ingredients for effective broad-spectrum control of hard-to-kill weeds such as bindii and white clover.
Effective across a broad range of warm and cool season turf species, including Buffalo and Kikuyu. This easy-to-use, low-rate formulation reduces the need for manual hand weeding, while improving the appearance and durability of the turf it is applied to – making it more resilient to foot traffic and other environmental stress. ESTATE® provides excellent turf safety, and its non-ester formulation reduces the potential for drift and off-target damage. 

How does ESTATE® work?

The 3-way blend of herbicides work well in combination and play slightly different roles in weed control:
- MCPA (Group 4): Moves through the plant accumulating in growing points of the stems interfering with cell division.
- Clopyralid (Group 4): Accumulates in the main growing points, causing rapid growth and eventual death.
- Diflufenican (Group 12): Inhibits the production of carotenoids, preventing photosynthesis.

Applerich Good Stuff is a premium granular fertiliser for year-round lawn maintenance, developed with Perth's sandy coastal soils specifically in mind. The formulation delivers rapid green-up with sustained colour and growth through a carefully balanced nitrogen split — 23% total nitrogen with 50% in controlled-release form.

The controlled-release nitrogen component is the key advantage over standard granular fertilisers. Rather than releasing all available nitrogen immediately — which leads to a rapid flush of growth followed by a quick return to pale colour as the nutrient leaches through Perth's free-draining sandy soil — controlled-release nitrogen feeds steadily over 8 to 10 weeks. The result is more consistent colour, more even growth and better value per application.

Iron and potassium are included in the blend for colour depth and stress resistance. Compatible with all turf varieties. Covers 200m² per bag at the standard application rate.

Use Good Stuff as your base granular fertiliser in a program that includes liquid top-ups with Applerich Oh My Goodness between applications for sustained colour through all seasons.

Applerich Good Stuff is:

• Suitable for all lawn types.

• Can also be integrated with Applerich Oh My Goodness as part of the yearly maintenance program.

• Potassium builds strength to cope with stress and disease.

• Once watered in, it is safe for pets or people.

Applerich Oh My Goodness is a liquid fertiliser formulated for foliar application — applied as a fine spray directly onto the lawn, nutrients are absorbed through the leaf blade within hours for a fast and visible colour response.

The formulation includes iron and potassium as key active components. Iron drives chlorophyll production and is the primary driver of the deep green colour response. Potassium strengthens cell walls and improves stress tolerance — making Oh My Goodness particularly effective as a winter maintenance product when cold and wet conditions put pressure on turf health.

Organic acids in the formulation assist nutrient uptake through the leaf and reduce the risk of tip burn from over-application. Safe to use alongside Plant Growth Regulators (PGR).

Available in 1L and 5L concentrate formats. 1L covers 500m², 5L covers 2500m². Apply through a pump sprayer or knapsack at the recommended dilution rate.

Lawnporn Moist is a professional grade soil wetter, designed to maximise water usage and availability in the root zone of lawn. MOIST is a unique combination of powerful surfactant technologies fullling different roles in the water management process.

Treatment for water repellent soil. A premium lawn hydration solution.

Knights Wetta is a professional-grade liquid wetting agent for treating and preventing hydrophobic soil in Perth lawns. Perth's sandy soils are highly susceptible to water repellency — over time, a coating of organic compounds builds up on sand particles that causes water to bead off rather than penetrate. The result is that even regular watering fails to reach the root zone, leaving lawns dry and stressed despite appearing adequately irrigated.

Knights Wetta breaks down this hydrophobic coating, restoring the soil's ability to absorb and hold moisture. Applied through a hose-on applicator or diluted in a sprayer, it works within days — the simple test of pouring water on a treated area and watching it soak in rather than bead off confirms the difference immediately.

Apply every 6 to 8 weeks through the growing season, or when signs of water repellency appear — dry patches that remain brown despite watering, water running off the surface, or soil that feels dry below the surface even after irrigation.

Compatible with all turf varieties and safe for use on all soil types.
