Spray drift measurements have been performed to quantify the effect of variations in wind angle and wind speed during application and the sprayer boom movement alongside the sprayed edge of the field on spray drift deposition alongside a sprayed potato field (2007-2008). Results of these spray drift measurements are used to develop spray drift models incorporating the effects of wind variability and sprayer boom movement on spray drift deposition. Measured spray drift deposition patterns are analysed based on the wind field and sprayer boom movements measured during the spray drift experiments. Models have been developed incorporating the variability of the windfield and the sprayer boom movement calculating the trajectories of individual packages of spray drift from discrete nozzle positions in time during the spraying of the edge of the field. The addition of sprayer boom movement in the spray drift model over wind field alone improved the calculated results of spray drift deposition variation alongside the field.
