Barrier H is designed for the control of the notifiable weed Common Ragwort (Senecio Jacobaea). Shake the container vigourously before use. A spot-spray, ideally using a knapsack sprayer with a long lance, Barrier H acts quickly on to the plants sprayed. On an ideal day to spray (low wind and dry day) the plants blacken up within an hour or so, helping to track which plants have been sprayed.
