A field application method to assess the impact of abraded dust on honeybees (Apis mellifera L.); Silvio Knaebe et al

Drift of abraded dust of insecticidal seed treatments has resulted in bee poisoning incidents in the past. For risk assessment purposes, tests with realistic applications of defined amounts of dust are needed, e.g. to determine NOEC or LOEC values. However, tests with dust are more difficult than liquid substance tests...
