BEN = bensulide (Prefar) 8 NAP = napropamide (Devrinol) 15
CAP = caprylic and capric acids (Suppress) un OXY = oxyfluorfen (Goal, GoalTender) 14

* Permit required from county agricultural commissioner for purchase or use.
1 Group numbers are assigned by the Weed Science Society of America (WSSA) according to different modes of action. Although weeds may exhibit multiple resistance across many groups, use mode-of-action group numbers to plan mixtures or rotations of herbicides with different modes of action.
