1. Select nozzle type. (See Nozzle Selection Guide & chemical label) 1. Select nozzle type. (See Nozzle Selection Guide & chemical label)
Example: RF Drift Reduction Raindrop Flat Spray tip for broadcast application of post-emerge contact herbicide Example: RE Even Flat Spray tip for banding application of pre-emerge herbicide.
2. Select GPA from chemical label 2. Select desired GPA from chemical label
Example: 20 GPA (broadcast rate) Example: 20 GPA (broadcast rate)
3. Determine tractor/sprayer speed in MPH 3. Determine tractor/sprayer speed in MPH

Example: Refer to the capacity chart for the RF tips. Look at the column headed "capacity one nozzle (GPM)" and find .34 GPM at the pressure desired. Example: Refer to the capacity chart for the RE tips. Look at the column headed "capacity one nozzle (GPM)" and find .17 GPM at the pressure desired.
The RF 3, 4, or 5 would provide the correct flow at 50, 30, or 20 PSI respectively. The RE 80-2RE would be correct when used at 30 PSI and 5 mpg.
