Par 3/Trillion/Killex and any other broadleaf herbicide won't do a thing to them. Non-selective is the only way to go if the dabber is your thing, but with quackgrass you might get part of it, but those rhizomes can keep it alive. Pull out a clump, mow lawn lower for a while might keep it at bay. Killing everything would be the overkill way to deal with it, but is one of the ways.

How do I tell the difference? It’s warm so do I have crabgrass? If I take a clump to a knowledgeable garden shop maybe they can tell me and how to kill it. What do you mean by “dabber?”
