We would spray marestail with full rate of Gramaxone and the highest rate of oil recommended plus an extra "splash" or so of oil in the spray tank. With decent coverage, in few days the marestail would be crispy. It has been a while since I did so, but I think I used 1.5-2 pints of COC instead of the 1 pint rate.
