Selective Spraying• Spray only where there are weeds
• Apply only as much material as necessary
• Economical high-speed operation

Application Speed
• Weedseeker: <10 mph agricultural applications
• Manual Control: inaccurate at speed
• Can be configured for any speed the spray system will support.

REPORTING & REGULATORY COMPLIANCE
GPS
Reporting• GPS allows reports listing chemical totals
by State, County and Zip Code
2009 Perceptive Robotics, LLC
Reporting• Camera goes beyond-GPS accuracy in
reporting material application
• Recording weeds provides detailed justification to regulators

NPDES Compliance Tool
• NPDES permits are required to treat “on or near” waters of the U.S.
• High accuracy application mapping shows which areas were treated
Avoiding drift & documenting wind speed
• Ultrasonic wind-meter provides accurate measurements of wind speed every second while moving.
• Document that wind-speed complied with drift regulations.
• Set wind-speed warning thresholds for normal operation and ecologically sensitive areas
• Import warnings from sites like driftwatch.org
INFORMATION EFFICIENCY
Example of Information Driven Efficiency
• Speed = amount of herbicide applied– Each nozzle size is designed for a
particular speed• Too fast Under spray area• Too slow Over spray area
• How much is application speed costing us?– Or how are results suffering from under-
applying?• Are our nozzles the right size?
Actual application speed

Actual Speeds
How much is application speed wasting?$4/acre (10% of total)
What’s Next• Long-term monitoring of herbicide
application and weed pressure– When to treat?– What to use?
What’s Next?• Crossing visibility analysis:
• Track condition monitoring
