Been applying for over 10 yrs and nutsedge wasn't an issue to really speak of until the last few yrs. Around here MSMA was the standard and used in blanket apps in June and there was very few lawns to spot spray sedge then. Now its out of control. Ive went through a dozen bottles of Pro Sedge and about 20 pounds of Solitare this season. I'm really glad that I haven't been including the control of it in my base prices. The Pro Sedge is better than Solitare and Dismiss in my opinion it does take longer to see results but no burn at all from it.
