TO DRASTICALLY REDUCE PESTICIDES USES: TWO CASES OF REDESIGNED SYSTEMS WITH BIODYNAMIC AND PROTECTED DESIGNATION OF ORIGIN CONSTRAINTS

摘要

ELI and France have decided for their agricultural policy in the next years to drastically reduce inputs and especially pesticides use in vineyards before 2018. Agricultural policy makers are responding by calling for more and more sustainable production systems. In this context, redesigning all sort of cropping systems has become a major challenge for agricultural professionals (Le Bellec et al., 2012). For the last years, agricultural researchers have been re-designed methods and tools to facilitate the design of innovative production systems (Cerf et al., 2012; Metral et al., 2012; Meynard, 2012). Working with winegrowers at the very beginning of the re-design process of the system is not very often done. Using directly very low input-pesticidessystems, i.e. biodynamic ones, to re-design is also another challenge.
