Increasing airspeed without changing the spray output will lead to:

Increasing airspeed while keeping the spray output constant will lead to less pesticide active ingredient being applied per acre. This phenomenon occurs because as the aircraft moves faster over a field, the time spent applying the pesticide over a specific area decreases.

When the spray output remains the same, but the coverage area grows due to higher speed, the overall amount of pesticide deposited per unit area — or per acre — is diminished. Essentially, while the total volume of pesticide released does not change, the increase in speed reduces the effective coverage of that pesticide over the targeted area, thereby decreasing the pesticide application rate on a per-acre basis.

This concept is crucial for aerial applicators to understand as it directly influences the effectiveness of pest control measures and environmental safety. Proper management of airspeed and spray output is essential for achieving the desired pesticide application effectiveness while minimizing waste.
