In a series of indoor experiments spray drift potential was assessed when spraying over a drift test bench (ISO 22401) with two different forward speeds (2 and 4m/s), two different spray boom height (30 and 50 cm), and two different nozzle spacing (25 and 50 cm), for six different nozzle types. The nozzle 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. An horizontal patternator was used to check the cross distribution for the different nozzle types and settings. For drift potential quantification a certain amount of fluorescent tracer (Brillant Sulfo Flavine) was added into the sprayer's tank. Potential spray drift deposition was measured placing collectors along the test bench quantifying the deposition of the spray plume behind moving spray boom in wind still conditions. Results obtained from two laboratories set ups differ because of the variability of relative humidity in one laboratory. Spray drift reducing capability was different at different settings depending on the nozzle type.
