Pest Control Aircraft Pilot Practice Test

What is the primary factor that affects the amount of pesticide applied per acre?

1. The airspeed of the aircraft

2. The type of pesticide used

3. The altitude of the aircraft

4. The design of the nozzles

The correct answer is: The airspeed of the aircraft

The primary factor affecting the amount of pesticide applied per acre is strongly influenced by the airspeed of the aircraft. When an aircraft is moving at a higher airspeed during application, the pesticide is dispersed over a larger area in a shorter time frame. This results in a lower volume of pesticide being deposited per acre because the same amount of material is spread over a greater distance, changing the overall application rate. Although the type of pesticide, the altitude of the aircraft, and the design of the nozzles can significantly impact the efficacy, coverage, and drift potential of the application, the airspeed directly determines how much pesticide reaches the ground in relation to the area being covered. This makes airspeed the most immediate factor affecting the application rate, particularly in aerial applications, where timing and speed can critically alter the effectiveness of the pest control strategy.
