Abstract

Because the application process of plant protection products is such a complicated matter with lots of influencing factors, a three-partnership project was started in 2009 in which a user-friendly software will be developed to understand and improve this application process in orchards. This paper discusses results from deposition field trials performed on the branches of leafed and bare trees. Generally, the deposition on the wood is higher in bare trees since the canopy of leafed trees acts as a filter for the spray droplets. Each machine tested, an axial fan sprayer, a cross-flow sprayer and a sprayer with individual spouts, generates its own typical distribution pattern that may be affected by the canopy architectures (hedge of Tienen, V-hedge, bush-spindle, vertical axe). The results presented here are valuable for the given weather conditions but lack reliability under different meteorological circumstances. They will be used to validate the model that is discussed further in this issue. In conclusion, this paper clearly shows that under certain weather conditions, the deposit of plant protection products on the branches, and thus the efficiency of the application, is an interplay between sprayer characteristics, tree architecture and phenological phase.
