Overview of pesticide spraying drones in modern agriculture

What is a pesticide spraying drone?

A pesticide spraying drone is an unmanned aerial vehicle (UAV) equipped with a liquid tank and an automated spraying system. It operates by dispersing fine mist over crops along GPS-programmed flight paths or under manual control.

The basic structure includes a flight frame, liquid tank, spray nozzles, sensors, and a GPS navigation system for precise targeting.

Today, popular agricultural drone brands such as DJI Agras, XAG, and Hylio are widely used across various crops - from rice and corn to sugarcane and fruit trees.

Why are spraying drones popular in agriculture?

  • The trend toward automation reduces manual labor costs.
  • Drones enhance spraying precision, ensuring even crop care.
  • Government programs support high-tech agriculture through credit and training initiatives.

Thanks to these advantages, pesticide spraying drones are becoming an essential tool in modern agricultural production.


Benefits of investing in pesticide spraying drones

Saving time and labor costs

A single operator using a pesticide spraying drone can spray 10–20 hectares per day, compared to only 1–2 hectares by hand. This helps farmers save significant time and labor expenses, especially during peak seasons.

Accurate spraying and higher crop yields

Ultra-fine mist technology ensures even coverage on leaves, reducing waste and saving 20–30% of chemicals. Crops are evenly protected, pest rates drop sharply, and yields increase noticeably.

Health safety and environmental protection

Drones prevent direct human exposure to toxic chemicals while controlling spray volume precisely, minimizing drift into air and water - contributing to ecological protection.

Easy management and scalable operations

Modern pesticide spraying drones can integrate with smart mapping software, allowing farmers to monitor spraying data, plan field operations, and easily expand cultivation to dozens of hectares without additional manpower.


Challenges and limitations of using spraying drones

High initial investment cost

A high-quality pesticide spraying drone typically costs between 150–300 million VND (approx. USD 6,000–12,000), excluding batteries and maintenance - posing a challenge for smallholder farmers.

Operation and maintenance skills required

Operators must be trained in flight control, spray calibration, and routine maintenance. Incorrect operation can cause malfunctions or safety risks during flight.

Weather and terrain limitations

Drones perform best in dry, calm weather. Strong winds, rain, or uneven terrain may affect spray accuracy and flight stability.

Legal framework and registration requirements

Under current regulations, agricultural drone users must register their equipment and obtain flight permits. This ensures aviation safety and legal compliance.


Comparison between spraying drones and traditional methods

Spraying speed and productivity

  • Drone: 10–15 hectares per day.
  • Manual spraying: 1–2 hectares per day.

→ Productivity increases 5–10 times, especially during peak farming periods.

Chemical consumption and pest control efficiency

Drones reduce pesticide use by 20–30% while achieving more uniform coverage and lower pest recurrence rates.

Labor and maintenance costs

Although drones require higher upfront investment, farmers can recover costs within 1–2 crop seasons thanks to savings in labor and chemical use. Maintenance costs remain relatively low.

Safety and convenience

Drones minimize exposure to harmful chemicals and can operate in dangerous or hard-to-reach areas such as flooded fields and sloped terrains.


Should farmers invest in pesticide spraying drones?

Analysis by farming scale

  • Large-scale farms (≥10 ha): Worth purchasing a drone for higher efficiency and quick payback.
  • Small-scale farms (<3 ha): Better to hire drone spraying services to reduce upfront costs.
  • Cooperatives: Can share equipment to maximize usage and cost efficiency.

Long-term economic efficiency

Investing in pesticide spraying drones helps reduce labor, save on chemical use, and improve yields. Farmers often recover their investment within 1–2 crop cycles, gaining 15–25% higher profits than with manual spraying.

Practical advice before investing

  • Choose reputable brands with official warranty service.
  • Attend basic drone operation and maintenance training.
  • Leverage financial aid or rental programs before large-scale purchase.

Applications across different crops

  • Rice: Effective control of leaf rollers and brown planthoppers.
  • Fruit trees: Uniform canopy spraying and reduced flower drop.
  • Coffee and pepper: Ideal for steep terrains, minimizing water use.

Maintenance and operation guidelines for spraying drones

Pre-flight checklist

  1. Inspect battery, nozzles, liquid levels, and GPS system.
  2. Set appropriate flight paths and spraying altitude for each crop type.

Regular maintenance for longer lifespan

  • Clean spray nozzles after every use.
  • Replace batteries after 250–300 charge cycles.
  • Update flight software periodically.

Government support and future trends in agricultural drones

Current support policies in Vietnam

  • Provincial programs offer preferential credit for high-tech agriculture.
  • Installment or full-service drone spraying programs for farmers.

Future technological trends (next 5 years)

  • AI and NDVI mapping integration for precision spraying.
  • Hybrid drones combining aerial and ground robotics with auto-charging.
  • IoT and seasonal yield analysis integration.

Pesticide spraying drones are proving essential in digital agriculture transformation. Despite initial investment and technical challenges, they significantly reduce labor, boost productivity, and protect the environment.

Investing in pesticide spraying drones is not just a trend but a long-term profitable strategy. When chosen and managed properly, they empower farmers toward smart, sustainable, and high-yield farming - the inevitable path for modern agriculture.


Frequently asked questions about pesticide spraying drones

Do spraying drones require registration or flight permits?

Yes. In Vietnam, spraying drones are categorized as remotely controlled aircraft, requiring registration and authorization to ensure aviation safety.

Can pesticide spraying drones operate at night?

Not recommended. Night operations reduce sensor accuracy and visibility. Some advanced models feature positioning lights and radar, but early morning or late afternoon flights are ideal for best results.

How often should the nozzles and batteries be replaced?

Typically, replace spray nozzles after 200–300 working hours and batteries after 250–350 charge cycles to maintain stable flight performance.

Can drones be used on sloped or uneven terrain?

Yes, if equipped with terrain-following radar and altitude sensors, which stabilize spraying on hillsides and uneven fields like coffee or pepper farms.

Are drone spraying services available for farmers?

Absolutely. Many providers offer full-service spraying at 35,000–60,000 VND per hectare, allowing farmers to experience modern technology without purchasing a drone.
