The implementation of precision farming and cropping systems optimization concepts for plant protection in vine are currently facing a difficulty: the quantities of product received per unit area of plant to be protected are poorly known. Doses are registered per hectare of ground and the ratio between the quantities sprayed and received on the plant depends on sprayer performance and on crop growth stage. The objective of ArchiTechDoseViti project was to understand the plant-equipment-spray relationships. Methods for sampling of deposits and for plant characterization have been developed on the EvaSprayViti artificial vine bench and in the field. A sensing system based on a 2D LiDAR has been proposed. The empirical models developed are a step towards predictive modelling of deposits and precision spraying. By taking into account the growth of the plant to protect for choosing the dose rate, quantities of inputs for the vine crop in France may probably be reduced by 20 or 30%.
