When I told them I tried Quinclorac, they told me, "won't be effective"!, they said the species of crabgrass we have in our area (Bakersfield, ca), is not effected by the stuff. The problem is, I would like to kill the large patches that have spread, however, I just purchased and put down some pre emergent with fert since it was never done since I purchased this house about a year ago, so if I kill those patches, I cannot throw down anymore seed for a while. I am assuming that no further spread of crabgrass will happen since I used a pre emergent? If I wait and kill the crabgrass once I can reseed, what would some suggestions be?" The shop guy mentioned using an old golf club with a sponge attached to dab the crabgrass with roundup. If roundup is effective, which product would be best? thanks..
