    I sprayed a big patch of yellow nutsedge. Manage on the left. Surge in the center and T-Zone on the right. All appeared to be somewhat effective, and turned the nutsedge first yellow, then brown. Manage (now marketed as Sedgehammer) worked slower at first.

    T-Zone and Surge are labeled to only suppress nutsedge, Surge only when it first emerges. So I wouldn't expect any control. How about also trying Basagran with a spreader/sticker? I would like to see how to stacks up against halosulfuron (Sedgehammer). My experience this year with Basagran is that it is a quick kill but proper application is critical to provide control while avoiding burning. You can't just spray to wet.

    I do not have any Basagran--and I don't plan on buying any for the small mount that I would need--sorry.
    I agree that Surge and T-Zone probably have mainly contact action due to the sulfentrazone ingredient. Quick action, though.

    Certainty w/ MSO has worked pretty well for me. Takes about a week to yellow up the Nutsedge, but it knocks it out.

    If I had a small amount left in a jug I would send it to you. Maybe next year.
