What is the difference with T-Zone and Speedzone?

I have cool season lawn and need to know if I should purchase T-Zone or Speedzone for the most effectiveness of more weeds year around.


In addition to 2,4-D and Dicamba also found in Speedzone, TZone SE Herbicide contains different active ingredients Sulfentrazone and Triclopyr and will control a broader range of weeds including yellow nutsedge suppression.  Speedzone will only control broadleaf weeds.  Which you use depends on the target weeds you would need to treat.
