    Does anyone know if quinclorac and carfentrazone are compatible? I have a little Drive left in the tank and I'm going to spray vessel and QS on some heavy broadleaf infested lawns.

    Yes! Q4 has both products. I would not go overboard on the carfentrazone in quicksilver I apply no more than 1oz max of the product per acre.

    Actually, Q4 has Sulfentrazone, not Carfentrazone. Sulfentrazone is in Dismiss, a Nutsedge control.

    I would recommend checking the label first...and if no info about it then do a compatability test or jar test as some call it.

    That will tell you what you need to know very quickly.

    YES, i have sprayed that combo a few times with ok results,
    not spectacular on large established broadleafs( like plantain)

    but it has worked well for spraying newly seeded jobs,
    about 60 days after seeding--helps knock down the young
    crab pants and the young broadleafs and saplings
