Abstract/Summary A combined spray and plant architecture model (Dorr et al. 2008) was used to determine the influence of droplet properties on the distribution of pesticides after spray application. The distribution of the spray was influenced by wind speed, release height, droplet size, spray sheet velocity, range of droplet size generated from a nozzle, liquid density and ∆T. Fan angle, flowrate, amount of active ingredient, surface tension, viscosity and splash parameter (K) did not have a significant effect on the modelled spray distribution. Increasing the splash parameter (droplets are more likely to splash on impact increased the number of droplets on the plant surface without significantly reducing the total spray volume on the canopy. This indicates that when droplet splash on impact, many of the smaller droplets generated are distributed on other parts of the plant canopy and hence increase coverage.
