Poa Annua germinates primarily in the fall each year so you would want to use a pre emergent herbicide in the fall to help keep it from coming up the following year. Hi Yield Weed & Grass Stopper with Dimension is a fantastic product and one of many we carry that would do a great job for you. It can be hard to get rid of poa annua in lawns with a post emergent depending on what kind of turfgrass you may have. If you want to let us know what turf you have we can see if we have a post emergent product that would work for you. Hi-Yield Weed and Grass Stopper with Dimension Herbicide can be applied from late summer through early fall (late August through November). When applied in the fall, a sequential or second application of this product must be made the following spring to provide season-long control of crabgrass. If this product is applied in the fall, do not reseed, overseed or sprig turf grasses within 12 weeks after application. We would recommend contacting your local extension office for the best time to apply this product in your county.
