For a specified application rate, which nozzle should an applicator choose if the requirements are 12 gal/ac and a medium to coarse spray?

The selected option features a gray tip XR11006 nozzle operated at 40 psi, which is suitable for achieving an application rate of 12 gallons per acre while delivering a medium to coarse spray.

Nozzle size and operating pressure significantly affect the droplet size and spray pattern when applying pesticides. The XR11006 nozzle is designed to produce a droplet spectrum that aligns with the medium to coarse spray requirements specified.

Operating the XR11006 at 40 psi ensures that the nozzle delivers adequate flow to meet the application rate of 12 gal/ac effectively. This pressure supports the optimal performance of the nozzle, allowing it to produce droplets that are not too fine, which could drift, nor too coarse, which could result in incomplete coverage.

Nozzles are designed to operate within specific pressure ranges to provide the desired spray characteristics, and the combination of the XR11006 at 40 psi achieves a balance that meets the specified requirements while maintaining the desired spray quality. This choice reflects an understanding of both the hydraulic principles affecting spray patterns and the environmental considerations necessary for effective and responsible pesticide application.
