Tenacity is labeled to control yellow nutsedge only, so it could be you are treating purple nutsedge, or kyllinga, which is in the same family and looks similar to sedges. If you have applied the Tenacity to the sedge with a surfactant and it has not died out completely and is only white after 5 weeks we would suggest to go ahead and try the Sedgehammer on any new growth. Sedge control products are supposed to be very slow killing so that it can try to move through the whole plant and roots as much as possible. Sedgehammer can take at least 3-5 weeks to kill down to the root and can be reapplied after 6 weeks if a second application is needed.
SedgeHammer Herbicide is only labeled to control kylinga, yellow, purple nutsedge and a small number of other weeds but it’s not labeled for clover.
