Gestion innovante du risque phytosanitaire lié à un bio agresseur invasif en cultures légumières

The document presents results of experiments and new procedures for the management of the nutsedge (Cyperus Esculentus) adapted to infestation levels and varied pedoclimatic conditions for Normandy production basins. An important part is devoted to the adaptation of material making it possible to extract the reproductive organs from the nutsedge, including in particular the tubers, and to make this tool non-existent to date efficient. The project also concerns the prevention aspects of new contaminations It is also a question of supporting and pooling knowledge within the regional sector to improve the consideration of the problem and adopt the necessary measures for its control at regional level.
