Physical weed control in urban hard surfaces and turfgrasses.

Weed management is a major issue not only in agriculture but also in cities and in public and sport turfs. Weed development often generates negative aesthetic effects, a sense sloppiness, mechanical damages to hard surfaces, the reduction of visibility for drivers, the reduction of the quality of the quality of the turf, and can make difficult for pedestrians to walk. Specific trials were carried out in order to develop and set up machines and techniques for weed control in urban and sub-urban areas and on turfs.
