I finished planting what corn could plant a week ago Friday.  I finished in the rain with 1/2" of rain then since Saturday I have received 3-4.5" across 200 acres.  The corn is non GMO and it is emerging.  Waterhemp, grass, giant ragweed and everything else that's bad.  This is long term notill.  IF it doesn't rain tomorrow, (80% chance of 1.2") I should be able to run it Monday.  What should I use for grass?  I plan on Banvel, a quart of atrazine, and coc for broadleaves.  I was thinking Steadfast ATZ  ANY and I mean Any suggestions are welcome even sarcasm. 

I'm located just north of  Route 80 in Illinois by Ottawa.
