Check for leaks. Select nozzles that provide the desired droplet size, flow rate, and pattern. Mount nozzles tightly to their positions. Watch the nozzles periodically to detect clogging. Operate the tractor at a uniform speed to ensure uniform application.
Double speed halves the application rate.
Keep the proper height at all sections of the boom. Set the pressure within the recommended range. Do not run the pump without liquid in the tank. Always calibrate the sprayer for application of the exact amount of chemical needed. See ISU extension publication Pm-817 for a calibration procedure.
