Barricade (Lesco Stonewall), or Dimension are both excellent. However, for best results, you need to apply at the high end of the recommended rate. You should probably be using the .15 percent Dimension. Aim for about .25 lbs active ingredient (dithiopyr) per acre. At least use the higher rate in crabgrass prone areas. Shade areas seldom need crabgrass control. Sunny areas, thin areas, and areas with a crabgrass history definately need the higher rates. Calibrate your spreader so that you can open it up two notches or whatever it works out. So you can treat the crabgrass prone areas with the higher rate and clean up the problem. Be sure to cover the edges and along the pavement fully. Do not let your customers power edge if they have crabgrass problems. This breaks the barrier along the pavement, (whoops, sorry Smallaxe) resulting in crabgrass along the edge. If you think you climate is "southern" use the southern rate.
