What is the recommended air pressure for applying pesticides with a compressed air sprayer?

The recommended air pressure for applying pesticides with a compressed air sprayer is typically in the range of 20-30 PSI. This pressure range strikes an ideal balance for effective pesticide application. At this pressure, droplets are adequately sized for optimal coverage without producing excessive drift or larger droplets that may not adhere well to the targeted surfaces.

Applying at a lower pressure may result in insufficient atomization of the pesticide, leading to uneven coverage or missed areas. Conversely, using higher pressures could create very small droplets that are more prone to drift away from the target area due to wind or air currents, reducing the effectiveness of the application and potentially exposing non-target areas to unwanted chemical exposure.

Therefore, the 20-30 PSI range ensures efficient delivery of the pesticide while minimizing the risks associated with both under-application and drift.
