Pesticide Spraying Using Drones: Benefits, Challenges & Adoption in Rural India

Byvinod@KrishiAadhar

Agriculture in India is changing faster than ever. With rising labour shortages, unpredictable weather, and the need for precision in farming, traditional pesticide spraying methods are becoming less effective and more expensive. This is where agricultural drones are making a massive difference—especially in rural India.

Drone spraying is no longer a future concept; it is happening today, across paddy fields, sugarcane belts, cotton zones, and horticulture farms. Farmers—from small landholders to large growers—are adopting drone technology to reduce costs, increase efficiency, and improve crop health.

This blog explains how pesticide spraying with drones works, its benefits, the challenges farmers face, and the current adoption trend in rural India.

What is Drone-Based Pesticide Spraying?

Drone spraying uses DGCA-approved agricultural drones equipped with:

  • Liquid tanks (10L–20L capacity)
  • Nozzles & atomizers
  • GPS navigation
  • Flow control systems
  • Spray booms or rotary atomizers

The drone flies at a low altitude and sprays pesticides or fertilizers uniformly across the field. The pilot plans a route, uploads the map, and the drone sprays automatically with high accuracy.

Benefits of Drone Spraying

Drone spraying brings value not only to large farms but also to small farmers in villages. Here are the biggest advantages:

1. Saves Labour Cost & Time

Traditional spraying requires:

  • 2–3 labourers
  • 4–6 hours per acre
  • Physical effort under hot sun
  • Constant walking with sprayers

A drone can spray 1 acre in 7–10 minutes.

This reduces labour dependency and costs, especially during peak agricultural seasons when manpower is scarce.

2. Better Chemical Coverage & Precision

Drone nozzles produce fine droplets, ensuring:

  • Uniform coverage
  • Better pest control
  • Reduced chemical wastage by 20–30%

This directly increases yield and reduces pesticide cost.

3. Safe for the Farmer

Manual spraying exposes farmers to harmful chemicals. Drone spraying keeps the operator at a safe distance, reducing:

  • Skin issues
  • Eye irritation
  • Lung and respiratory problems

Farmer safety is one of the biggest advantages.

4. Saves Water

Manual spraying uses 150–200 litres per acre.
Drones need just 7–10 litres per acre.

This is critical for drought-prone regions and water-scarce farms.

5. Suitable for All Crop Types

Drone spraying works well for:

  • Paddy
  • Cotton
  • Sugarcane
  • Maize
  • Vegetables
  • Banana plantations
  • Horticulture crops

Hill regions and uneven terrains benefit even more because drones don’t need flat land.

6. Increases Yield

With precision spraying, farmers get:

  • Healthier crops
  • Fewer pest attacks
  • Reduced crop damage

This leads to better yield and higher profits.

Challenges in Drone Spraying

While drone spraying is promising, farmers still face some barriers.

1. High Cost of Drones

DGCA-approved drones cost between ₹3–8 lakhs, which is expensive for small farmers. Most rural farmers prefer service-based models, paying per acre rather than buying drones.

This is exactly where platforms like KrishiAadhar help by connecting farmers with certified drone service providers.

2. Limited Awareness in Villages

Many farmers do not know:

  • How drones work
  • Whether spraying is safe
  • Which chemicals to use
  • Whom to contact

Awareness programs and demonstrations are needed.

3. Skill Requirement

Spraying must be done by certified RPTO-trained pilots.
Villages often lack trained pilots.

Government-backed training and more drone academies are improving this situation.

4. Battery Limitations

A drone can spray 2–3 acres per battery.
Multiple batteries and chargers are needed for prolonged operations.

5. Weather Dependency

Drones cannot fly in:

  • Heavy winds
  • Rain
  • Storm-like conditions

This requires careful planning around weather.

Adoption of Drone Spraying in Rural India

Drone adoption is growing rapidly across rural India due to three big drivers:

1. Government Push & Subsidies

Under schemes like:

  • SMAM subsidy
  • Custom Hiring Centres
  • Kisan Drone Program

The government is actively promoting drone spraying.

2. Increase in Drone Service Providers

Today, hundreds of companies and local entrepreneurs operate:

  • Drone spraying services
  • AMC & maintenance
  • Training centres

This makes drones easily accessible even in small villages.

3. Farmer Demand for Faster & Cheaper Spraying

Farmers want:

  • Quick coverage
  • Reduced labour dependency
  • Better yield

Drone spraying proves itself in every demo, leading to immediate adoption.

Future of Drone Spraying in India

Within the next 3–5 years, rural India will see:

  • Mandatory drone spraying for certain crops
  • Drone-based pest monitoring
  • AI-driven spray recommendations
  • Drone-as-a-service models becoming standard
  • Big cooperatives & FPOs adopting drones at scale

Drone spraying will become as common as tractor ploughing.

Final Thoughts

Drone-based pesticide spraying is transforming Indian agriculture by making farming:

  • Safer
  • Faster
  • More profitable
  • More sustainable

While challenges remain, adoption is accelerating across rural India. Through platforms like KrishiAadhar, farmers can easily book drone spraying services, connect with certified pilots, and bring cutting-edge farming technology directly to their fields.
