1. What Are Variable-Rate Pesticide Application Drones?
   VRA drones are advanced UAVs equipped with multispectral cameras, GPS systems, and AI-powered controllers that adjust pesticide application rates dynamically based on real-time field data. Unlike conventional drones that apply uniform amounts, these drones target specific zones with tailored dosages, minimizing waste and environmental impact.

Key Components:

• Multispectral Sensors: Detect pest hotspots, crop stress, and soil health variations.
• AI Algorithms: Analyze data to predict pest risks and optimize spray patterns.
• Variable-Rate Nozzles: Adjust flow rates on-the-fly for precise chemical delivery.

2. How Do VRA Drones Work?
3. Data Collection: Drones map fields using multispectral imaging to identify variability in crop health, moisture levels, and pest activity.
4. Data Analysis: AI processes the data to create prescription maps, highlighting areas needing treatment.
5. Targeted Spraying: Drones follow the map, adjusting nozzle rates dynamically. For example:

• Apply higher pesticide doses in pest-infested zones.
• Reduce rates in healthy areas to conserve chemicals.
