parameters of the nozzles are different from the European nozzles. In this study, one series of the drift reduction nozzles under different nozzle-pressure combong>inong>ations were tested ong>inong> the wong>inong>d tunnel ong>inong> order to estimate the drift reduction performance ong>basedong> on one reference spray. Additionally, the ong>inong>fluences of the nozzle size, pressure and height on the DPRP values were also ong>inong>vestigated. 2. Materials and methods 2.1 Wong>inong>d tunnel parameters and measurong>inong>g protocol The wong>inong>d tunnel experiment was carried out ong>inong> the Bio-oriented Technology Research Advancement Institution (BRAIN), Saitama city, ong>Japanong>. The dimensions of the wong>inong>d tunnel were illustrated ong>inong> Fig. 1. To obtaong>inong> the vertical deposits of each nozzle-pressure combong>inong>ation under different nozzle heights at the same time, the nozzle was ong>inong>stalled at 1.2m above the floor and 6 polyethylene long>inong>es (V 1 ~V 6 ) were placed horizontally across the wong>inong>d tunnel 2m downwong>inong>d with the heights from 0.7m to 1.2m at an ong>inong>terval of 0.1m, respectively. A tracer (Solium fluoresceong>inong>, 200ppm) and a non-ionic surfactant (Tween 20, 0.1%) were used ong>inong> this study. After sprayong>inong>g, the collector long>inong>es were washed ong>inong> 100ml de-ionized water and the liquid was taken to measure the tracer concentration value. The volume of the spray liquid deposited on each collector long>inong>e was obtaong>inong>ed by calculation. FIGURE 1: The dimensions of the wong>inong>d tunnel and the sketch of drift potential measurement ong>inong> the wong>inong>d tunnel by usong>inong>g polyethylene long>inong>es Table 1 showed the nozzle ong>inong>formation and environmental parameters of the nozzles ong>inong>vestigated ong>inong> this study. The Hypro ISO F 110 03 standard flat fan nozzle with a nozzle pressure of 0.3MPa and a nozzle height of 0.5m was used as the reference spray. The YAMAHO KIRINASHI ES nozzles were recommended to use with a nozzle height between 0.3~0.4m. The spray time of the nozzle-pressure combong>inong>ations was 10s when the flow rate was above 0.8L mong>inong> -1 and 20s for the other combong>inong>ations.

In the calculation process, the nozzle heights were 0.5m for the reference spray while the nozzle heights were 0.4m and 0.3m for the ES series nozzles ong>basedong> on the manufacturer recommendation. The details of the calculation equations could be found ong>inong> the above reference.

Thus, the nozzle heights which equal the vertical distance between the nozzle and the lowest collector long>inong>e were 0.5m, 0.4m and 0.3m. The nozzle drift ong>classificationong> for the nozzle-pressure combong>inong>ations ong>inong>vestigated was carried out followong>inong>g the methods adopted by German Federal Biological Research Centre for Agriculture and Forestry Braunschweig (BBA) (Herbst, 2001).
