Why is the pressure measurement important in a spray system?

The measurement of pressure in a spray system is crucial because it directly influences how the pesticide or herbicide is distributed and its effectiveness in reaching the intended targets. When pressure levels are appropriate, the spray can produce the ideal droplet size and spray pattern necessary for proper coverage of the area being treated. This ensures that the chemicals are efficiently applied to the plants or water bodies, maximizing their impact against the aquatic pests while minimizing waste and potential drift to non-target areas.

Inadequate pressure can lead to larger droplets that may not effectively reach the desired locations, while excessive pressure can create small droplets that may drift away from the target due to wind. Consequently, maintaining optimal pressure is essential for both the efficacy of the treatment and for environmental safety.
