Residue studies DFR

A DFR (Dislodgeable Foliar Residue) study measures residues that can be transferred from the leaf surface to another surface (OECD GD (97)148).

The objective of this type of trial is, among others, to estimate the risk exposure of workers who are in contact with crops at harvest for long periods of time.

We have all the necessary equipment at our disposal to perform this type of trial. We have leaf punchers of different diametres to test a range of different crops.
