Croplands WEED-IT QUADRO User Manual page 114

The spray width nozzle is the spray width of one nozzle at the soil surface, and is important for an optimal spot spray
result. The following table indicates in green what configurations are best suitable for spot spraying. Each detection
channel is 25 cm wide, and so the spray width must be at least 25 cm.
Note that the nozzle height is configured in the WEED-IT by your dealer and that the spray boom must stay at this nozzle
height to ensure the weed is detected and hit with herbicide optimally.
In the table spray widths up to 45 cm (so with 10 cm overlap at both sides) are indicated as suitable. However, rough
conditions, such as uneven terrain or unstable spray booms may require a larger spray width.
