Réduction du nombre de molécules herbicides : conséquences par culture. Problématique particulière de la gestion de la flore adventice

Abstract : All national and European legislations contribute to the present reduction in the available herbicide number. This evolution leads to the decrease in the number of chemical families and to a dramatic reduction of the number of modes of action in some crops or crop rotations. This could lead to the selection of new herbicide resistances. So we may find contrasted situations: crops weeded with only a few herbicides or some herbicides used in almost all crops. The drastic reduction in the available active ingredients without taking into account the benefit-risk ratio or without planning realistic alternative solutions may create tougher agronomic constraints. A data base built up from all the available herbicides in France since 1944 allows quantifying these issues according to the different crops and weed species.
