There is a pressing need to quantify more fully the fate of ULV spray droplets dispersed over agricultural crops. For this purpose, field experiments were performed under various meteorological conditions of wind speed and turbulence level. Quantified atomizers were employed, giving known droplet diameter spectra. Vertical profiles of droplets impacting onto thin cylindrical collectors were measured at many stations up to 160 m downwind and at heights up to 12 m; they are presented in graphical form. They are also compared with available diffusion theories.
