Has anyone ever used this product and achived good results with it. I tried mixing MSMA 6.6 with Trimec Classic and applied it to several lawns with a skid sprayer. Seemed to me that the MSMA did knock back the crabgrass and nutsedge somewhat....however, I was never able to completly rid a lawn from annual grasses. Also had a few spots were I overapplied the MSMA and shot holes in the grass. I'm thinking a boom type sprayer would probably be better to apply chemicals like MSMA rather than using a skid type sprayer.
