The Broadacre Challenge

Australian grain properties average 3,000+ hectares. At that scale, weed management isn't a task — it's a logistics operation.

The maths of broadacre weeding are brutal. A single herbicide-resistant ryegrass plant in a wheat paddock can produce 40,000 seeds. Multiply that across a few thousand hectares, and you're facing an exponential problem that traditional blanket spraying alone cannot solve. Resistance is building faster than new chemistries can be developed — Group A and B resistance in ryegrass is now widespread across southern Australia, and glyphosate resistance is accelerating.

Hand weeding at broadacre scale is physically impossible. Even a well-organised crew can only cover a few hectares per day. Drone mapping provides valuable aerial reconnaissance, but the turnaround from flight to actionable treatment can take days — time that fast-growing summer weeds use to set seed.

WeedBot Pro was purpose-built for this operating environment: large paddocks, variable soil types, unpredictable weather, and weeds that won't wait for your schedule.

Fleet Coordination

Multiple WeedBots working together, managed from a single dashboard.

🗺️

Central Dashboard

Monitor every robot in your fleet from a single web-based interface. See real-time position, battery level, coverage progress, and weed density overlays on your paddock maps. Reassign units to priority areas with a click.

📡

GPS Weed Heat Maps

Every weed identification is GPS-tagged and logged. Over successive passes, WeedBot builds detailed heat maps showing weed density and species distribution across your property — intelligence you can use to guide variable-rate spraying and inform rotation decisions.

🔄

Autonomous Path Planning

Upload your paddock boundaries and each WeedBot calculates optimal coverage patterns automatically. Units communicate with each other to avoid overlap and ensure complete ground coverage, including headlands and around obstacles.

🔗

Farm Software Integration

Export weed data directly to John Deere Operations Center, Climate FieldView, AgWorld, PAM, or any system that accepts shapefile or GeoJSON formats. API access is available for custom integration with your agronomist's software.

Where WeedBot Fits Your Program

WeedBot complements your existing spray operations — it doesn't replace them.

🌾

Fallow Cleanup

The highest-value application. Deploy WeedBots during fallow periods to keep paddocks clean without repeated blanket sprays. Particularly effective against summer weeds like fleabane and feathertop Rhodes grass that germinate in waves.

🌱

Pre-Sowing Knockdown

Run WeedBots through paddocks 2-3 weeks before sowing to eliminate early germinations with targeted micro-doses. Reduces reliance on pre-emergent chemistry and starts your crop with a clean seedbed.

📊

Variable-Rate Spray Guidance

Even when you do need a blanket spray pass, WeedBot's GPS weed maps let you run variable-rate application — full rate in hot spots, reduced rate in clean zones. Growers typically save 30-40% on chemical costs per pass.

Proven Across Australian Crops

Wheat & Barley

Tested extensively across the NSW slopes, Victorian Wimmera, and WA wheatbelt. WeedBot's narrow profile moves between standing stubble rows without disturbance to no-till soil structure.

Canola

Canola's broad leaf architecture makes crop-weed discrimination straightforward for WeedBot's AI. Particularly effective for controlling volunteer cereals and brassica weeds in canola rotations.

Chickpeas & Pulses

Pulse crops are notoriously poor weed competitors. WeedBot's precision targeting is especially valuable here — every weed removed in a chickpea crop directly protects yield potential.

Sorghum & Summer Crops

Wide row spacings in summer crops give WeedBot ample room to operate. Inter-row weed control that would be impractical with a boom spray becomes straightforward with targeted robotic treatment.

"We run three WeedBots across 4,200 hectares. They cover the fallow country between harvest and sowing — a window when we used to do two blanket glyphosate passes. Last season we cut our fallow herbicide bill by 70% and the paddocks went into sowing cleaner than I've ever seen."

Frequently Asked Questions

How many robots do I need for 5,000 hectares?

At 40-60 hectares per day per unit, a fleet of 3-4 WeedBots can complete a full pass of a 5,000 hectare property in approximately 3-4 weeks. Most broadacre operators start with 2 units to cover priority paddocks (fallows and pulse crops), then scale up based on results. We provide a detailed coverage plan based on your specific paddock layout, rotation, and weed pressure history.

Can it work alongside my spray rig?

WeedBot is designed to complement your existing spray program, not replace it. Many growers use WeedBot for targeted fallow cleanup, inter-row work, and spot treatment of resistant patches, then follow up with blanket application where weed density warrants it. The GPS weed maps WeedBot generates can even guide variable-rate prescription maps for your boom spray, reducing overall chemical usage by 30-40%.

Does it integrate with my farm management system?

Yes. WeedBot exports weed density maps, treatment logs, species distribution data, and coverage reports in industry-standard formats (shapefile, GeoJSON, CSV). Direct integration is available for John Deere Operations Center, Climate FieldView, AgWorld, and PAM. An open API is also available for custom connections to your agronomist's preferred platform.
