Does this product also prevent germination of existing poa?

I have annua poa but want to stop more germination and seeding from current plants. Can I apply this in summer?

Answer:

Hi-Yield Weed and Grass Stopper with Dimension Herbicide is labeled for pre emergent control of annual bluegrass. For poa annua, the best time to apply is in the spring when soil temps are around 55 degrees and in the fall when soil temps drop to around 70 degrees.
