Here in California, 95% of my lawns are a 90/10 Fescue/bluegrass mix and have used Manage for over 4 years now with good success. Have had the same bottle for that long and finally ran out. Went to Horizon to pick some more up but they don't have Manage anymore, just Sedgehammer and Certainty. He was out of the big bottle's of sedgehammer but had the certainty so I bought it. The guy told me they were practically the same thing. Got home and read the label and it says it's not labeled for many cool season turfgrasses and actually controls tall fescue? What do I use for nutsedge control on fescue lawns? Certainty is made by Monsanto so thought they just changed the name. I'm confused!
