    In this MN lawn, this grass just started coming up the last few weeks, it has some tubular parts that are very tough and will not cut easily. As you can see it is a clumping grass.

    Looks like perrenial ryegrass from the seed head.

    Koester, I agree, perennial rye, judging by the seed head. Probably one of the older, tougher varieties. Is your season later than ours? LOL!

    The seed head indicates it is quack grass. Quack grass has a rye type seed head also. The bunching habit would indicate tall fescue. If the leave blades have clasping auricles it is quack. Maybe you have both. A couple applications of Certainty will take care of either.

    certainty takes care of quack, but kills rye grass? what grass doesn't it kill? KGB? TTTF?

    At .5 oz/acre Certainty is labeled for perennial rye.

    The clumps look like K-31.

    Don't think Certainty is license for home lawns here yet. Wish it was. Until it is, Round-up on a paint brush....
