The evaluation of the latest data on spray drift in orchard spraying in the Netherlands, and measurements of surface water quality parameters show that the current legislation and measures are insufficient to protect the surface water. To meet the national and European objectives regarding surface water quality also a reduction of chemical input is required. New strategies have to be developed to retain chemicals for crop protection and a clean environment. Latest developments showed great perspectives for multiple row orchard sprayers. The use of these types of sprayers has increased dramatically in the Netherlands in recent years. It is proven that multiple row sprayers reduce spray drift significantly. It is assumed that spray depositions are improved when spraying with multiple row sprayers and dose can therefore be reduced accordingly, without reducing biological efficacy. The objective is to find the optimum combination of application parameters for different stages of canopy development to reduce spray drift while improving spray deposition. In a series of trials, spray deposition measurements were carried out following the ISO-22522 protocol. In the experiments multiple row orchard sprayers of two manufacturers (Munckhof and KWH), were compared to a conventional cross-flow fan sprayer (Munckhof).
