Was just getting ready to spray some glyphosate and sharpen ahead of wheat.  Was thinking about adding a few ounces of 2,4-D just for another mode of action.  Would that help or be too risky?   
 Also need to spray some ground going  cover crop rye.  Was thinking of 2,4-D and Dicamba.  Could actually be a little time in between till that gets planted.  If its not going to harvest will it have a noticeable affect?
