Yes, Dimension 2EW Herbicide is labeled for centipede and will provide pre emergent control of poa annua. Pre emergents typically need to be applied when soil temps are just under 55 degrees in early spring and under 70 degrees in late fall for best results however timing can vary depending on your region. Please view the product label for more information. We recommend contacting the Master Gardener at your local cooperative extension office for their advise on the best time this year to apply pre emergents as it can vary depending on weather and environmental factors.
