Résistance aux inhibiteurs de l’ALS chez le séneçon commun (Senecio vulgaris) : la situation en vigne et en grandes cultures

Resistance to ALS-inhibiting herbicides in common groundsel (Senecio vulgaris) : situation in franch vineyards and major field crops. Common groundsel (Senecio vulgaris) is a ubiquitous weed that is highly mobile and which seeds can germinate almost all year long. It also is the only weed species today in France that is officially acknowledged to have evolved a resistance to one same herbicide mode of action both in vineyards and major field crops. The purpose of this paper is to provide a picture of a few major aspects of this resistance: underlying mechanisms, detection, seed viability, spread and geographical extent of the resistance.
