Some beans had 5 ozs of Perpetuo on them right after they came up. Some had 3 pints of Ledger(dual and Sencor) post plant pre emerge. Beans have been sloooowwwwww all spring. Have a couple fields with emerged waterhemp that I'm thinking about just hitting with Liberty and Roundup because I really don't want to stunt these plants any more. Beans planted April 26 are barely 8". 

Would there be a residual I could put on, mainly for waterhemp, that wouldn't speckle them? Zidua? I know that Anthem Maxx and Warrant will curl them up. 

Thanks.
