What Chem does everyone use to prevent/ kill grass In their corn? (Ours is for edible corn)

We have a grass problem in our corn and it’s beginning to stunt the growth of the corn. Planted with corn is potatoes in the same field, and the potatoes have 0 grass in it. Any suggestions?

Depending on the grass Impact at. 75 oz with MSO.

Should be 3/4 an oz.

Barnyard grass is getting hard to control, Impact @ 0.75 oz or Laudis @ 3 oz per acre with MSO at full rate and AMS will work.

I use 1 oz of Impact plus MSO at 1 pt. Per acre and get along fine.

Would metolachlor be good to use for pre emerged weeds?

How tall is the grass if it's stunting corn growth? 1 Oz impact or 3 Oz Landis also use just 1 or 2 OZ of status to kill any broadleaf. Impact/ status is one of best post herbicide app if RR not available. Not supposed to spray impact too late on corn or it will buggy whip tassels. What growth stage is corn?

And definitely use tank mix of mso with it also and could use Laudis now and impact in couple weeks if grass is real tall. You Chem provider will advise against it, because of crop rotation but I've never had a problem. Only use 2nd app is really needed.
