Abstract

A field study was conducted in November 2013 to assess the drift reduction potential of a three headed sprayhood unit with either DG9502 or DG95015 lowdrift nozzles used with the hoods either on or off (DG nozzles calibrated at 06 litres/min) A standard treatment of 11003 nozzles calibrated at 125 litres/min without hoods was the control One tank mix of 04 g/litre PTSA (1368pyrenetetrasulfonic acid tetrasodium salt) fluorescent dye was used for all treatments Petri dishes and aluminium plate collectors were placed at 025 05 1 2 5 10 25 50 and 100 m downwind in three lines spaced at 10 m Collectors were placed in plastic bags under cool dark storage until analysis Results showed that total drift was reduced up to 99 compared to the control when the spray hoods where used
