    Last August (optimal timing), we spot sprayed Corsair at the highest rate & included the correct spreader/sticker (from LESCO). Currently, no tall fescue has died on the nine lawns we used it on. What's the deal????? I'm thinking Roundup is the answer? Help is needed here. RSCVP

    We don't see any Fescue down here but I use this stuff for Virginia Buttonweed.

    Did you do the 2nd application 60 days later?

    The label suggests using a non-ionic surfactant @ .25oz per gallon and making a 2nd application 60 days later on:

    Smutgrass, Tall Fescue, Vir Buttonweed, and Wild Violet

    Good Luck :)

    BTW - What type of grass(if any) are you trying to keep on these lawns? I assume the fescue is an unwanted grass growing in another grass?

    Some of the weeds on Corsair's label can be taken out without a follow-up app, but I think you're taking your chances if you don't do a follow-up on Tall Fescue Buddy.

    I applied Cetainty to several lawns in May. It is slowly taking out the tall fescue and quackgrass. I scheduled a second application for one lawn but we have not had rain in three weeks. I am going to wait until August. I went at the .5 oz/acre rate.

    Thanks very much guys. I only made one application. Checked most of the treated lawns a month after the treatment (last fall) -- all tall fescue clumps were yellowing, so I figured they were on their way out. This spring, I noticed the clumps looked healthy as ever. OOPS. Now I'm thinking this two-application thing is time consuming, and I wonder if customers will pay what it's worth compared to Roundup???

    Certainty is not that expensive. Most of my customers would be willing to pay for two applications.
