    Im sorry if this is the wrong forum to ask. I figured it would be a good place since people spraying would be able to tell.

    By looking at the pics I took, are you able to tell if this is yellow or purple nutsedge? It obviously doesn't have flowers. I know that purple has rhizomes connected in chains and yellow does not. I'll admit, I am not confident in saying I know exactly what that difference would look like.

    Can someone help me out?

    Dismiss by FMC will kill it regardless if it is purple or yellow.

    Ok thanks.

    I already sprayed Q4 and I know that only treats yellow. I thought I knew thats what it was. I admit I made a mistake and should have known 100% before hand.

    That's why I am asking if its yellow or purple.

    come on man. I sprayed it with Q4 and am curious since Q4 only treats yellow nutsedge and not purple.

    Doesn't Q4 have sulfentrazone in it? The same ingredient that is Dismiss? And also, I though Q4 only supressed nutsedge, not killed it. I didn't think it had enough Sulfentrazone in it. I may be wrong though, I dont use Q4.

    I used Q4PLUS. The label says it controls yellow nutsedge.

    I posted this 3.5 hours ago and nobody can say definitively if this is purple or yellow?
