Pesticides are commonly applied by using hydraulic nozzles to generate droplets. The
properties of these spray droplets can influence the effectiveness and risks associated with
the use of pesticides. Initial spray characteristics (initial droplet size and velocity, fan angle
and spray liquid density) were therefore measured for a range of hydraulic nozzles and
spray mixtures. Particle Image Velocimetry (PIV) was used to measure the spray sheet
velocity. There was a significant difference between a standard hydraulic nozzle, Turbo …
