    Uittreksel

    Research on the effect of tree architecture has mainly focussed on the effects of tree training on fruit yield and quality (Lauri and Laurens, 2005; Whiting et al., 2005; Costes et al., 2006). The different tree architectures developed with the intention of only increasing the fruit yield and quality might have a negative effect on the efficiency of plant protection product applications. Therefore, experimental and modelling approaches have been used in this work to assess the pesticide distribution in different plant training systems and compare the performance of different spraying machines for the different training systems. Four training systems (Apple classical, Pear classical, Pear T-hedge and Pear V-hedge) and three different spraying machines (a radial sprayer, a cross flow sprayer and a sprayer with individual air jets) were studied in this assessment. The performance of the sprayers is compared using the deposition they give on different parts of each training system (leaf and stem) and ground.
