Can Poa Constrictor Herbicide be used in the spring to treat for poa annua (annual bluegrass) in a Turf Type Tall Fescue lawn? Can I overseed at the same time as applying Poa Constrictor Herbicide?


Poa annua germinates primarily in the fall, and turf type Tall Fescue is also typically overseeded in the fall rather than spring, because this is when the seed takes best in the year. That is likely why the Poa Constrictor label states only fall instructions in the seeding and timing rate table on the Product Label. In general, if its safe to be used in the fall, you should be able to do the same in the spring, its just not the normal season, and you would only get spotty poa annua prevention since the majority of the cycle occurred this past fall/winter.
