A simple approach for a spatial terrestrial exposure assessment of the insecticide fenoxycarb based on a high‐resolution landscape analysis

摘要

BACKGROUNDThe objective was to refine the standard regulatory exposure scenario used in plant protection product authorisations by developing a more realistic landscape‐related GIS‐based exposure assessment for terrestrial non‐target arthropods. We quantified the proportion of adjacent off‐target area in agricultural landscapes potentially exposed to insecticide drift from applications of the active substance fenoxycarb. High‐resolution imagery, landscape classification and subsequent stepwise analysis of a whole landscape using drift and interception functions were applied to selected areas in representative fruit‐producing regions in Germany.
