Been buying Cimarron Plus for several seasons, it is excellent for killing weeds, mixed by directions and it will not harm your grass, now i have control of weeds trying to grow in my grass. I use a very small amount mixed in my 15 gallon sprayer
My yard had become full of "state" grass. All the other grass would still be low and nice but those other sprigs would be so tall and thick, I would have mow every week. I needed to mow every 3 days really. I mowed, sprayed my yard with Cimarron and after 1 application I have not mowed my grass in 2 weeks! It did not harm my other grass. It only killed the state grass. I had a few pop up and have sprayed them and will mow. It works great so far.
