Additional data for Germany were kindly provided by RRAC, CropLife International, Brussels, Belgium; Bayer AG, Monheim, Germany. Additional data for Lower Saxony were kindly provided by Freise and Runge, Landesamt für Verbraucherschutz und Lebensmittelsicherheit (LAVES), Hannover/Oldenburg, Germany, and Esther, Julius Kuehn Institute, Muenster, Germany. Geographical co-ordinates were rounded to a level of uncertainty, which does not allow to conclude on addresses with confirmed resistance on the map. The center of a coloured resistance spot deviates by minimum 2km from the site of resistance sampling.
