Most universities have a weed control guide. The one below has a pretty thorough table for pre and post herbicide effectiveness (1A & 1B). One of the first columns is corn tolerance. The known risky herbicides are rated a "3". The 1's should be no problem and a little 2's you may want to pay attention not to group too many of them together.
