New constraints and requirements have recently appeared in the field of viticulture. Firstly, the range of herbicides available to the practitioners of viticulture has been markedly reduced; this is as much the consequence of numerous withdrawn registrations, as that of restrictions enforced now in several different production systems and labels. Secondly, there is a consensual awareness nowadays that soils and their fertility need better protection, what generates new constraints in areas such as weeding techniques, with a special emphasis on mechanical soil management. Thirdly, the increased support for biodiversity in the agricultural landscape has substantially complicated the management of the spontaneous flora within the vineyards. This article itemizes and describes these new constraints, while presenting their consequences for the practice of viticulture. The article also presents the available solutions and discusses the need for further innovations.
