Methods To Control Corn Prior To Replanting

By Daniel Stephenson, Ph.D.

Many producers are having to replant corn due to poor stands. There are three main ways to remove a failed corn stand.

  1. Use tillage equipment to physically remove the existing corn.

  2. Apply 0.0469 lb clethodim/acre and wait six days before planting the second corn crop. That equals 6 ounces of a 1 lb/gal clethodim, 3 ounces of a 2 lb/gal clethodim or 2 ounces of a 3 lb/gal clethodim. Waiting six days before planting is critical to prevent injury.

  3. Apply 0.625 lb paraquat/acre plus atrazine at 1 pint/A or diuron at 1 pint/A or metribuzin at 3 oz/A. Good coverage is essential. Even then, don’t expect outstanding control with this choice.
