If you have real CRW pressure bifentherin is not going to do much of anything.  

You need traited corn with multiple modes of CRW protection and/or Aztec or Force dry insecticide, or Index if liquid is the only option.      All of those insecticide options are much more expensive than Bifentherin, but they’ll actually do something to protect your roots from CRW.   

If long term CoC is what you’re trying to do you might want to start checking for beetles in season and doing beetle bombing to lower egg counts for the next year.  

Spending $30 (or more) per acre to control CRW is a lot but it won’t seem that bad vs scrapping down corn off of the ground.     Down corn is pure misery and very hard of your combine and head.
