The Dutch government’s policy (Environmental Activities Decree, Sustainable Crop Protection 2) has set goals for the reduction of the emission of plant protection products into the environment. Data are needed on actual spray drift and drift reducing measures when spraying a plant protection product to support decision making on the authorisation of the use of plant protection products in different crop types (Board for the Authorisation of Plant Protection Products and Biocides, Ctgb). The WUR Drift Calculator (WDC) is introduced in 2021 for use in the authorisation procedure of plant protection products (Ctgb) from January 2022 onwards. The WDC is based on updated spray drift data from spray drift measurements in the period 1995-2005. This means ongoing and new procedures up till that date of introduction may still use the spray drift values as used in the authorisation procedure and based on spray drift measurements in the period 1995-1999. This report provides tables of spray drift deposition from boom spray applications on the different evaluation zones until the WDC is in place in the authorisation procedures. Results are presented in a matrix of Drift Reducing Technology (DRT) versus crop-free buffer zone for applications in a bare ground situation and a crop situation. Data were extrapolated from performed spray drift experiments; in order to assess spray drift deposits for the distance at which the off-field threshold level to protect non-target terrestrial arthropods (NTA), non-target terrestrial plants (NTP) and surface water (SW) is likely to be met when spraying a plant protection product onto a crop, or onto a bare soil/short crop situation. When using boom sprayers in field crops, in the authorisation procedure the standard spray drift deposition on the off-field evaluation zone was 10% of the applied dose for non-target arthropods (NTA), 4.7% for non- target plants (NTP) and 1.0% for surface water (SW) until the end of 2017. Since the 1st of January 2018 the Environmental Activities Decree ...
