Quackgrass in home lawn (Certainty and weed wick)
Hi. I have large sections of quackgrass that I believe was brought in from topsoil a landscaper put down. I bought some Certainty Sulfosulfuron herbicide (very expensive), but I'm not sure if putting that down would selectively rid of the quackgrass. I also bought a 'weed wick'.....which has a braided rope that gets soaked with herbicide - and then would be dragged across the taller blades of the quackgrass. If I used Roundup with the weed wick, would this kill the quackgrass rhizomes and leave the desirable grass alone. Please provide your thoughts on the Certainty and weed wick. Hoping to avoid non-selectively killing off large sections of lawn with Roundup. Thanks much - Doug

Thanks for the feedback. A few more questions......As far as the Certainty (Sulfosulfuron), would this damage perennial bluegrass? I could swear that I saw an earlier MSU write-up that suggested Sulfosulfuron to control quackgrass. I'm essentially asking if I definitely not use the Certainty at all.
With wicking using Roundup (I used weed and grass killer concentrate plus - with the red cap), when should I expect to see any results?
The total-kill (glyphosate) option is scary to me. Does MSU offer step-by-step instructions on application (including concentration), wait times, prep, fertilizing and seeding?
Thanks again - Doug
I hope this is helpful,
