    I broadcast sprayed Fusilade II on my TTTF lawn 2 weeks ago to kill a quackgrass invasion, which stunted the lawn and quackgrass growth, BUT this grassy weed is still growing in some spots.

    The stalk and blades look very thin:

    Haven't see it flower or seed at all. It gets up to 6" before I do my weekly mow.

    That's what I first thought but it's the same color as the grass and it doesn't have pointy ligules.

    Are you familiar with Fusilade (fluazifop) at all? Curious if you've had experience since I'm in the middle of trying it and would like to know what to expect. It's labeled for quackgrass kill and minimal damage to TTTF as along as it's not stressed and sprayed at 5-6 fl.oz/A. Theres a whole section on the label specifically on usage in TTTF and Zoysia to kill grassy weeds and bermudagrass.

    Never used Fusilade, not sure if it's labeled for use on KBG or Rye?

    Regardless, I used Certainty in the past and it was big fail. I got out of the quackgrass elimination business it's a hard biz to succeed in.

    Only TTTF and zoysia, it'll kill PRG and KBG (supposedly). Luckily I'm not in the business, just an irritated homeowner who had infested topsoil delivered for a reno last fall. Spent all winter researching, but just sprayed 2-ish weeks ago.

    More photos for weed ID. This was cut at 3.5" on Sunday and it's 5-6" on Tuesday:
