BARRICADE Turf Herbicide is the ultimate season long barricade against a wide range of pre-emergent grassy weeds. The combination of BARRICADE with the post emergent activity of either MONUMENT LIQUID Turf Herbicide or CASPER Turf Herbicide delivers total weed control options for grasses and broadleaf weeds. Early spring applications of BARRICADE will ensure season long control and mixing with MONUMENT LIQUID and/or CASPER provides you flexibility for broadleaf weeds, sedges or residual Poa annua.
