VALOR® 50 WP, herbicide for the control of grass weeds in pre-emergence and broadleaf, in pre and post emergence of weeds. It is recommended for grapevines, fruit trees (such as stone fruits, pomegranates, blueberries), pines and eucalyptus. In applications on the leaves of sensitive plants, flumioxazine is rapidly absorbed, causing desiccation, followed by necrosis of the affected organs. Symptoms are seen in less than a day. Applied to the soil, flumioxazine penetrates the stem and radicle of the germinating seeds, causing the necrosis of the latter and the inhibition of root growth.
