Joyce from Loganville Ga writes

Is Tenacity Herbicide labeled to kill poa annua (annual bluegrass)?

Answer:

Tenacity Herbicide is not labeled to control Poa Annua/Annual Bluegrass, it only states that it could cause injury to it if sprayed with tenacity. Since it is not specifically designed to control Poa Annua, a better product choice would be Echelon 4SC. Echelon 4SC is labeled for pre-emergent control of poa annua only. According to the product label, apply Echelon 4SC Herbicide in August or September to established, non overseeded turf before Poa Annua germinates. Consult your local Cooperative Extension Service for more specific applications timings for your local area since August and September are approximate timings.
