Will Poa Consticror be just as effective on poa triv (rough bluegrass), as it is poa anua (annual bluegrass)?


Poa Constrictor Herbicide is not labeled to treat poa trivialis.  Negate would be a great to option to use for poa trivialis on tolerant turf grasses. Please see the label for complete application instructions.
