Développement d’un outil d’aide à la décision pour la gestion intégrée des adventices

subject

description

Integrated weed management consists in using several weed management techniques in a long-term approach. The vast number of techniques precludes cropping systems from being easily conceived and climatic interactions render the systems difficult to pursue. Farmers and farm advisors need decision support systems (DSS) to develop weed management strategies adapted to multicriteria/multiobjectives of weed management, to the economic, social and environmental stakes and to the constraints of farmers. Such a DSS is developed from the mechanistic weed dynamic model FLORSYS. This model is a “virtual field” allowing the evaluation of the performance of agricultural systems over a large range of agricultural and pedoclimatic situations. Different stakeholders are associated with the tool development in order to adapt the prototypes to the farmers' objectives and constraints, via surveys, meetings and workshops with the future users.
