Flazasulfuron is the first sulfonyl urea safe to the established vines through a rapid detoxication into the plants and the first vines herbicides inhibiting the Als enzyme. It is effective at a low rate (50 g a.i./ha) and presents a favourable profile regarding toxicology and ecotoxicology. Mobile into the annual and biennial species, both grasses and broad leaved weeds, flazasulfuron is mostly effective preemergence to the weeds. Applied before the growing period of the vines, it generally achieves a weed control up to the harvest time (four to six months), thus limiting the number of treatments and the range of active ingredients. It is also effective post emergence and it is then usually completed by the addition of sulfosate to widen its weed spectrum and to improve its speed of action on the weeds already emerged at treatment time. In the present context of limiting the use of soil herbicides such as diuron or simazine and rotating herbicides with different modes of action, flazasulfuron belongs to a new generation of herbicides adapted to the integrated weed control management strategies in vines
