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.
