We have available a relatively rich arsenal of platforms (satellites, airplanes, UAVs, combines, ATVs), sensors and image processing procedures to detect weeds at various spatial and temporal scales. Up to now these technologies have been mainly used for map-based targeted herbicide spraying, improving the efficiency of this operation. In addition, they have been used for map-based mechanical weeding tools, facilitating the replacement of herbicide interventions. In the future, weed scouting may be used in the development of other low environmentally impacting interventions (competitive varieties, improved rotations ant tillage practices). In addition, it may be used in the redesign of weed management systems, facilitating collaborative research, providing new agroecological knowledge and improved cropping systems and allowing an automatic assessment of the impact of control activities.
