You're absolutely right, my mistake. I'm not sure why I thought it was 2,4,db. It still seems to me that buying a gallan of Butyrac and a gallon of Arrow or Select is cheaper than buying Slay, Pursuit or Raptor. Including COC, everything can be had for under $200 and there's enough for multiple treatments. I'm going by memory here, but doesn't Whitetail Institute's web site say that Slay will kill chicory?
