Abstract In a series of indoor experiments spray drift potential was assessed when spraying over a spray drift testbench with two different driving speeds, 2m/s and 4m/s, two different spray boom heights, 30 cm and 50 cm, and two different nozzle spacing, 25 cm and 50 cm, for six different nozzle types. The nozzles types used were the standard flat fan XR as a reference nozzle and the DG, XLTD, IDN, AIXR and AIRmix as drift reducing nozzles types. A Patternator was used to check the cross distribution for the different nozzle types and settings. Spraying tests were carried out by adding the fluorescent dye Brilliant Sulfo Flavine to the spray agent. Potential spray drift deposition was measured placing collectors along the testbench quantifying the deposition of the spray plume behind the moving spray boom in windstill conditions. Results obtained from two laboratories set ups differ because of the variability of relative humidity in one laboratory. Spray drift reducing capability can be different at different settings depending on the nozzle type.
