Spray drift and bystander risk from fruit crop spraying
In the EU-FP7-BROWSE project (Bystanders, Residents, Operators and WorkerS Exposure models for plant protection products) spray drift data measured in the Netherlands and the UK for orchard spraying are combined to develop a probabilistic empirical model of bystander and resident exposure to spray drift. The model requires data relating to airborne spray to determine dermal and inhaled exposure, and relating to ground deposits, to determine indirect dermal exposure to contaminated ground. The available data can discriminate between full leaf (BBCH 74¿92), the intermediate periods (BBCH 61¿73 and 93¿0) and the dormant (BBCH 0¿60) period. For the BROWSE model, reference curves are defined for axial and cross-flow fan sprayers for ground deposit and airborne drift for 0¿1 m and 0¿2 m heights above ground as functions of distance downwind.
