Sorry, I just wasn't thinking about that problem. With so much of the corn being RR and LL that can really make you use a product like Select. I have noticed I have several stalks of volunteer corn scattered around in our LL beans this year and I didn't even plant corn last year. I do have a couple fields that I didn't get the grass control I should have with the Liberty but I got a heavy rain right after spraying and I didn't respray.
