Buttonweed Treatment

Celsius was proven to be the most effective against it by a University study.

Either Celsius or MSM Turf, both are effective against VBW in this heat. Will stress the desirable lawn grass, but not kill it, if used at labeled rates for VBW. Add surfactant to the spray solution.

As mentioned, multiple applications is almost always required, at 3-4 week intervals, and if the VBW is mature (white flowers) it’s going to be more difficult to kill-control. You’ll have to be persistent with treatment through the remainder of summer-early fall - looking for new growth and spraying when you see it.

Is it too warm for msm? I also have vbw and also dollar weed

I believe the label says max temp 85 F but I’ve had an university weed control specialist tell me it can be safety used into the lows 90s and be OK. I have used it on hot days without issue but don’t exceed the max application labeled rate, and do expect some temporary yellowing and stunting of the surrounding turf grass.

I try to spray it early morning or late afternoon on 90 + F days.

I've said on here before, took me 3 yrs to get mine under control, I walked my yard almost everyday with a 1 gallon sprayer and hit it whenever I saw it
I hardly ever see it any more, but it gets hit when it rears it's ugly head

What is the label rate for MSM for this time of year. Per acre.
