Work carried out as part of the Casdar RT TechnoDoseViti project (2018-2021) identified the vegetation descriptors needed to predict the statistical distribution of deposits resulting from plant protection products sprayed within the plant canopy (Cheraiet et al., 2021). This experimental modelling work (Codis et al., 2018) has made it possible to build, calibrate and validate multivariate models for predicting the different deciles of the quantity of surface deposits in the plant canopy as a function of vegetation descriptors (height, thickness, and porosity of the canopy) measured using a mobile 2D LiDAR sensor enabling a 3D reconstruction of the vegetation (Cheraiet et al., 2019 & 2020). Models were developed and calibrated for different types of sprayers and different viticultural contexts (wide vines and narrow vines). The data was used to compare different technological scenarios consisting of different mechanisation strategies and different levels of equipment technology, in order to assess the potential contribution of precision application techniques in terms of phytosanitary inputs reduction. As part of the project, a web simulator has been developed: https://technodoseviti.hdigitag.fr
