There has been little corn planted to this point. Judging by the phone calls today some of that early planted corn will need to be replanted due to all the wet and cold weather. The question arises how to control the old corn stand and plant back to corn quickly.

There are several options to control a thin corn stand and replant back to corn.  Some of these options, like Select Max, need a waiting period before it can be planted back to corn.  Others, like tankmixes of paraquat plus atrazine, alow corn to be replanted right away.  Please find attached the results of a study Angela McClure and I conducted several years ago on destroying freeze damaged corn and replanting back to corn. We repeated the study the next year on a good stand of corn and got the same results. In this publication (Replanting corn in a failed corn stand) you will find a number of different herbicide options  that did a good job controlling an unwanted stand of corn.
