ISAA 2013, The use of adjuvanted formulations for drift control), determines the proportion of droplets in the spray, which contributes to the drift effect. The reduction of the fine drop fraction in the spray is therefore crucial for a reduction of the drift and is therefore used to determine the drift properties of a composition.
