Laboratory comparisons of nozzles that could be used to apply crop protection herbicides with a conventional ground sprayer were performed. Water sensitive paper (wsp) was placed under the simulated spray boom to collect spray droplets from each nozzle treatment. DropletScan software was used to analyze the wsp and determine differences in percent area coverage (PAC), deposition (GPA), and droplet size (DV0.5).
