You could potentially mix Crossbow and Killzall together, however since the Killzall is already a non-selective herbicide, then you usually would not need to do so. If you were mixing these products together for increased control of tougher woody plants, then you may consider mixing a straight triclopyr product such as Remedy Ultra or Southern Ag Brush Killer. Just keep in mind that the Killzall will affect any plants that you spray with it.
