Hi-Yield Weed and Grass Stopper with Dimension Herbicide does not list Virginia Buttonweed as a weed it prevents. We do not know of a pre-emergent that is labeled for buttonweed, as it is a difficult weed to kill. It usually takes multiple applications of post-emergent herbicides to treat it. Post-emergent product recommendations will be based on your desired turfgrass.
