Because of agronomical and environmental impact of this phenomenon, drift has been widely studied and large information is available. This paper consists of a literature review on the relationship between physical descriptors of agricultural sprays, air conditions and resulting drift, generally studied in wind tunnels. Basic physical factors are droplet size, droplet velocity, and physico-chemical characteristics of the sprayed product. When possible, data available in the literature are gathered to draw trends. Contradictory information can sometimes appear especially regarding droplet velocity and drift control. Main physical factors consist generally of medians such as Volume Median Diameter (VMD or Dv50) that do notthat do not always represent the heterogeneity into a spray and especially spatial distribution of particle size and velocity. Technological parameters such as nozzle height, spray angle, travel speed are then related to initial physical factors that may explain anti-drift performances by wind tunnel experiments and their contribution to driftability of sprays.
