N.W. Illinois | Banvel as a post is certainly better than Banvil as a pre. However Banvel or dicamba can still cause injury even as a post. Some hybrids will green snap much easier from a post application of Banvel. Most seed corn companies have a rating for the safety of dicamba on each hybrid. Adding atrazine to Banvil has a big synergy effect, you will have much better weed control. However Banvel stills has lousy residual so if you apply it to soon it will fade away and not control all the weeds. The bigger the corn the increase in green snap and other crop injury. Banvel also drifts easily dinging neighboring beans. Usually this is cosmetic but it can still cause ill will with neighbors.
There are much better post broadleaf herbicides available than Banvel, one being Callisto. Callisto with atrazine compared to Banvel and atrazine provides superior control, much longer residual, and much better crop safety. It costs more but is well worth it in my opinion.
Banvel has actually been replaced with a product called Status for weed control in corn. Status is a dry granular of dicamba with a safener in it that helps(?) prevent crop injury. In my experience Status drifts worse than Banvel.
