Which three variables affect the amount of spray material applied per area?

The amount of spray material applied per area is significantly influenced by the nozzle flow rate, groundspeed, and the width sprayed per nozzle.

The nozzle flow rate determines how much pesticide is being released from the nozzle, directly affecting the overall volume applied. A higher flow rate means more material is sprayed over a given period of time.

Groundspeed is crucial in determining how quickly a sprayer is moving across the field. If the groundspeed is too fast, the pesticide might not have enough time to adequately cover the area, leading to inadequate application rates or uneven coverage.

The width sprayed per nozzle indicates the coverage area of the spray pattern. A wider spray width means that each nozzle is effectively covering more ground per pass, which directly impacts the total amount of pesticide applied over a given area.

Together, these three variables allow for precise control over application rates, ensuring that the pesticide is applied at the right volume for effective pest management while minimizing waste and environmental impact.
