Screening level for the relevance of the succeeding crop exposure scenario based on different combinations of soil persistence (soil DegT50) and adsorption properties (Koc) of a substance and application rates (expressed as total annual application) to annual ‘double’ crops. The screening level is applicable only when all the toxicity endpoints (i.e. all the acute LD50 values, the LDD50 and the larval ED50) are ≥ 0.1 μg/bee. When the properties of a substance meet one of the combinations, an exposure assessment of the succeeding crop scenario is not needed
