What does 'ground speed' indicate in pesticide application?

Ground speed in the context of pesticide application refers to the speed at which the application equipment is moving over the ground when applying pesticides. It is typically expressed in miles per hour. This measurement is crucial because it affects the distribution pattern and deposition of the pesticide on the target area, ensuring effective coverage and minimizing drift.

Other units of measurement for speed, such as kilometers per hour, feet per minute, or meters per second, are valid in different contexts or regions but are not standard for pesticide application in many areas, particularly within the context where miles per hour is commonly used. Hence, the choice indicating that ground speed is measured in miles per hour aligns best with the practices and standards in pesticide application.
