Case Study: Precision Spot Spraying for Weed Control on Grazing Land

Client: Private Grazier

Location: Outside Cabarlah, QLD
Property Size: 420 acres (hilly terrain)
Service Provided: Spot spraying of Lantana and weed mapping using DJI T40 & M3M

The Challenge

The client was facing a growing infestation of Lantana and Fireweed on the steeper parts of the property. These areas were:

• Too dangerous for ground spraying with quad bikes

• Inaccessible to boom rigs or tractors

• Starting to impact pasture growth and grazing access

Manual spraying had been attempted in the past but was labour-intensive, inconsistent, and not sustainable over time.

Our Solution

Elevate Ag Solutions carried out a multispectral scan using the DJI M3M to identify and mark out heavy weed zones. We then:

• Created a spot spraying prescription map

• Flew the DJI T40 to apply targeted herbicide on mapped areas

• Navigated steep and uneven terrain with precision and no ground contact

The entire job was completed in under 4 hours, with no soil damage or operator risk.

The Results

• 100% of problem zones treated with high accuracy

• Zero damage to pasture or soil

• Estimated labour savings of 2+ days

• Client saved over 30% on chemical costs by avoiding blanket spraying

Client Feedback

“I used to dread spraying those hills. This was hands down the easiest, most effective way we’ve handled the weeds in years. I’ll be getting the drone in again next season.”

Key Takeaways

• Drone spot spraying is safer and faster than manual methods

• Multispectral mapping helps target infestations and reduce waste

• Ideal for grazing properties, steep paddocks, and remote areas
