What can cause uneven spray patterns during pesticide application?

Uneven spray patterns during pesticide application can often be attributed to a pressure setting that does not align with the optimal range for the nozzles being used. Each nozzle is designed to operate efficiently within a specific pressure range to achieve the desired droplet size and distribution. If the pressure is too high or too low, it can lead to larger droplets, fine mist, or inconsistent coverage, all of which contribute to uneven application.

While factors like incorrect nozzle size or improper calibration can also affect spray patterns, the specific influence of pressure setting on the performance of the nozzle makes it a critical element in ensuring uniformity. Understanding the operating range for different nozzle types is essential for achieving effective pest control while minimizing waste and environmental impact.
