    Scweedman--you asked about the difference. I listened to a weed expert presentation today by David Gartner of Ohio State U. I asked about the difference. If I understood, Carfentrazone can be used on moss, and on new grass.
    Sulfentrazone--very similar--but longer residual and it can also kill nutsedge. Otherwise similar.
    He also claims that with pendimethalin and Dimension--that "Split applications were not as effective as the same amount used all at once. "
    Anyone agree--disagree?
    For broadleaves he prefers fall treatments--especially in misty drizzle--feels that herbicide stays on leaf longer, and doesn't evaporate before it can be absorbed.
    Also said bromoxynil is fine for new grass at 7 days.
