During the spraying process, what impact does low pressure have on pesticide application?

Low pressure during the spraying process is beneficial as it reduces drift. Drift refers to the movement of pesticide away from the target area due to wind or other environmental factors. When the pressure is low, droplets produced by the spray are generally larger and heavier, which decreases the likelihood of them being carried away by wind, thus enhancing the accuracy of application and ensuring that more of the pesticide reaches the intended surface, whether that be plants, soil, or pests.

In contrast, higher pressure tends to produce finer droplets that are more susceptible to drifting with the wind, which can lead to pesticide loss from the target area, potential harm to non-target organisms, and environmental contamination. Therefore, using low pressure can lead to more effective pest control and lower risks associated with pesticide application.
