From BREAM. These drift values for field crops are also applied in the online calculator to low berries, low vegetables and low ornamentals (outdoor and indoor).
From Ganzelmeier/Rautmann (the 75th percentile is not published).
Early/late season (stage) is a parameter only relevant for bystanders and residents and is based upon measured drift deposits (Ganzelmeier/Rautmann), in which the values for orchards were displayed separately for early and late stages (without leaves and with leaves). This differentiation applies also to cane fruit/high berries (outdoor) but does not apply to oil fruits or citrus crops, which are not directly comparable to orchards since these crops are evergreen plants. For oil fruits and citrus crops only, late season is considered relevant and realistic as regards exposure of bystanders and residents by deposits based on drift.
The drift values for grapes are also applied in the online calculator to cane fruit/high berries (indoor), high vegetables, high ornamentals (outdoor and indoor).
