A survey concerning registration of plant protection products was carried out in 41 EPPO member countries. Twenty six countries responded and results are summarized in three groups. Various models are discussed which seek to adapt product dosage to the crowns of fruit‐tree crops. The tree row volume model (TRV) is favoured by the authors since it can adequately cope with the wide variability of orchards encountered across Europe. It is suggested that experimenters who carry out registration field trials should measure the height and width of the tree crowns and the distance between the tree rows to facilitate comparison of registration trials including residue data.
