  • Tenacity Herbicide
    By Fred Tefft on 6/3/2013
    Purchased for control of windmill grass in a buffalo grass lawn. I am using Tenacity and Dimension for pre-emergent control. Each product has specific weeds not controlled by the other.With a lot infested with windmill grass adjacent to my yard I was losing the battle. Cursing the day that DSMA and MSMA were banned, as they were good controls for windmill grass. My only choices were a hoe or glyphosate, both destructive to any lawn.Tenacity was made available for homeowner use in early 2012. Since then, my lawn is repairing from the use of glyphosate, and the windmill grass is being held in check. Tenacity does a good job on it. But it does not perform as well with broadleaf weeds as hoped. Post-emergence control of crabgrass is excellent. The part amazing is watching the plants turn white from a lack of chlorophyll. My only complaints about Tenacity are the cost and the limited availability, the latter is the result of local retailers refusing to carry the product. The cost is about the same as Dimension, so I can't complain too much.
