Or dandelions, poa annua.
You can use another herbicide at the same as using a pre-emergent such as Hi-Yield Weed and Grass Stopper with Dimension as long as you are following the product labels for what you are using. If you are putting down a post-emergent at the same time as your pre-emergent, then you will want to delay watering-in the pre-emergent for at least a day so that you do not wash away the post-emergent. (The Hi-Yield with Dimension must be watered in to be activated.) Most 2,4-D products will control dandelion, but that active ingredient will not kill nutsedge or poa annua. If you would like to tell us what type of turfgrass you have, then we can recommend products to kill these weeds.
