Is there a selective herbicide that will kill nimblewill in cool season turf yet? How do you guys deal with it?
Thanks,
Pete

Break out the Roundup and then slit-seed.

Really LGF??? According to PBI Gordon's Weed Alert they don't have a herbicide labeled for control of Nimblewill. Where did you get info. that MSMA will control it?????????

Do you have the ortho problem solver book ? Look on page 677 DSMA is a trade name for MSMA

Really?? DSMA and MSMA are one in the same?????????

nope,
Mono sodium Methyl Arsenate or Di-sodium Methyl Arsensate. May have some similar controls but haven't used them this century, lol.

Back in July, I was at the University of Kentucky's annual turf field day. During the cool season turfgrass tour, we were shown a plot of weeds\grasses that contained nimblewill. Next to that plot was a treated plot of grass that had no nimblewill. Dr. A.J. Powell, who was conducting the tour, indicated that they (UK) were testing "Mesotrione" (Syngenta, I think) as a selective herbicide for turf use. It killed the nimblewill.
The bad part to all of this is that mesotrione has not been labled for turf, and he didn't know when it might be labled. Probably after many millions of dollars have been paid to someone.

I do believe that mesotrione is labeled for agricultural use (corn).
