Dismiss is awesome. Takes care of a few other weeds also. Nutsedge is harder to kill and there are a limited number of herbicides that target it. They are also kind of expensive. I had been just buying single use packs that mix up a gallon or two of spray and doing it that way. But hell it cost around $20 for a packet that would make 2 gallons, and it takes me 4 gallons to cover my yard completely. Decided to bite the bullet and buy a 6 ounce container of Dismiss. Off the top of my head the mix rate is something like 0.275 ounces of product per 1000 sqft. I can basically get 6 full backpack sprayers out of one bottle. That would have cost me $240 using something like Sedgehammer, Monument, or ProSedge small dose packs. So looking at it that way spending $80 or so on the Dismiss was easier to justify. The weeds started browning the next day. Still haven't sprayed the back yard, I'll do that one evening this week if I catch one that is cooler and not windy. Being that getting even coverage using a hand can or backpack is difficult, I did get a small amount of discoloration on the turf in a few places. It goes away pretty quick and wasn't as severe as what I get when using MSMA. Some people will add in a small amount of chelated iron or liquid fertilizer to combat this, but I've yet to try it.
