generic acetochlor or metolachlor + atz + generic callisto. Add glyphosate if there's emerged grass.
If planning to come back with a post pass (all pre one pass seems pretty risky in my world), split callisto 2.5-3oz each and save some atrazine for the post pass, also. Or use dicamba/2-4,d pre instead of callisto for a different mode of action.
