Virginia buttonweed question

No, leave alone for a while. That is a lot of herbicide in a short time.

I've had good success with Celsius in the past but it does take multiple applications, about a month or 6 weeks apart. I've seen good things about MSM for buttonweed, but I always seem to burn my lawn with MSM.

I have some Mansion that I sprayed on some that was growing in my yard last year. Took about a week, but it killed it.

Virginian Buttonweed is listed on the “Image for Nutsedge” label for VBW control with multiple applications, but that is also true for MSM Turf (=Mansion), Celsius, Trimec, Weed Free Zone, etc. so off hand don’t see a negative in trying to use it for that purpose, particularly if you are spraying for sedges at the same time.


But I don’t see imazaquin as a recommended herbicide for VBW control on any land grant university extension VBW control fact sheet - which may mean the other herbicides recommended have proved to be more effective in VBW control in field research trials. Your call if you want to experiment with image for nutsedge for a follow up spray(s) or use MSM Turf or Celsius. Give the board your follow up assessment should you go with the imazaquin. Do make sure you wait 2 to 4 weeks between subsequent applications.

Patience & Persistence with VBW control.

Yes, I was surprised to see it listed on Image label info.

In my OP I mentioned I applied imazaquin 3 days ago (for several issues) and it has already put a mark on the VB

Celsius was proven the most effective by a study done at a college (can’t remember which)

Celsius is the go to. MSM works as well. One thing I always take into account is strength of mix. Label rate Celsius works better than label rate msm. MSM is much cheaper and more widely used. Homeowner Mr Joe mixes label rate plus a dash extra of msm and declares it the winner.

As mentioned here I’ve had really good luck with multiple apps of Celsius and msm….its just a patience thing, have to stay on it helps to start early in growing season.

Wish pasture herbicides like Chaparral (Aminopyralid plus MSM Turf essentially) and GrazonNext HL (Aminopyralid plus 2,4-D) were labeled for Bermuda lawns/turfgrass. Aminopyralid component in both is very good on VBW. Have smoked it in Bermuda pasture edge with the GrazonNext HL.
