Agriculture: Precision Spraying and Multispectral Scouting

Duty

Identify weed pressure early, generate a prescription map, and reduce herbicide use while maintaining control.

Before drones

Operators rely on scouting by walking or driving, which misses patches and over-treats whole blocks.

Technical stack

• Scout: Mavic 3M multispectral mapping flight
• Process: Field analytics to classify weed pressure zones and build a prescription
• Apply: Agras platform for spot spraying or variable rate zones

Outcome

Significant input reduction is possible when the prescription is tight and execution is repeatable. This is one of the highest ROI precision agriculture workflows because it links mapping directly to application.

Duty

Apply fungicide quickly across large acreage during a narrow weather window.

Before drones

Ground rigs can be delayed by wet soil, and aerial availability can be constrained.

Technical stack

• Plan: Field boundary plus obstacle awareness, consistent altitude above canopy
• Apply: Agras mission planning, repeatable flight lines, droplet and flow control

Outcome

Teams gain timing control, especially when the field is not trafficable. This is where drone spraying often beats a tractor in operational reality.

Duty

Use crop vigor maps to avoid over-application, then apply only where the crop needs it.

Before drones

Uniform rates across variable fields waste input and can create uneven results.

Technical stack

• Scout: Multispectral mapping, repeatable flights for time-series comparison
• Decide: Convert index maps to zones, assign treatment rules
• Apply: Agras application with tight coverage and repeatable routes

Outcome

Zone-based decisions reduce wasted input and make follow-up actions more targeted.

Duty

Treat high-value crops where terrain, plant spacing, and access make ground application inefficient.

Before drones

Hand spraying is labor heavy and inconsistent, ground rigs have access limitations.

Technical stack

• Plan: Terrain-following, obstacle-aware routes, row spacing matched to flight lines
• Apply: Focus on canopy penetration and drift control

Outcome

Better consistency, safer operator posture, and improved ability to respond quickly to outbreaks.

Duty

Spray and spread in waterlogged fields where machinery struggles, keep timing during peak pressure periods.

Before drones

Wet paddies limit tractor operations, labor constraints make manual spraying difficult.

Technical stack

• Apply: Agras mission planning optimized for paddies, consistent low-altitude routes

Outcome

Drones replace heavy manual work and help maintain on-time treatment in difficult access conditions.
