Drone Spraying Field Operations: Key Considerations
This guide offers practical questions and considerations to help set up your truck and trailer for drone spraying, tailored to your specific operation.
PPE: Always carry gloves, goggles, protective clothing, and respirators (if needed), based on MSDS requirements.
Clean Water & Soap: Keep a rinse tank and soap available for immediate decontamination in case of chemical spills.
Drone Flight Safety:
Maintain line of sight to avoid connection loss and for FAA compliance.
Create a clear, obstacle-free space for takeoff and landing.
Use barriers or distance to protect yourself during launch and recovery in case of drone malfunction.
Drone Tank Mixing: Simple but inefficient.
Bulk Premixing: Cost-effective using IBC totes or large tanks, but limits flexibility (can't adjust rate, risk of waste if plans change).
Cone-Bottom Tanks: Two 30+ gallon tanks recommended. Fill with clean water, add measured chemical, and recirculate. Safer and more flexible than bulk mixing.
Auto-Mixers: Systems like Agri Spray Drones’ automixer can save time—just ensure they are calibrated and perform jar tests for compatibility.
Always read and follow product labels.
Test product compatibility, especially at lower water volumes (e.g., 2 GPA vs. 15 GPA), to avoid separation and sludge.
Fungicides are especially prone to settling and clogging filters and pumps.
Choose a reliable transfer pump (gas or electric). Aim for a minimum of 20 GPM flow rate.
Ensure continuous duty cycle if using the pump for recirculation.
Filling should be fast—ideally under 30 seconds per tank.
Use ¾" minimum, 1" preferred. Reinforced suction hoses (green or yellow banded) help prevent kinking.
Fill nozzles: ¾" or 1" with auto-shutoff work, but may foam or clog over time.
For tight drone fill ports, use a filed-down 1" banjo valve with hose barb.
