Here are some other options if you run into the Roundup shortage/price increase situation.
- Use a Pre-mix: Acuron GT, Enlist Duo, Halex GT, and Sequence all have a roundup built in
- If you choose not to use Roundup, I would consider Anthem Maxx, Dual, Outlook, Prowl (POST application only), Warrant or Zidua for residual grass control
- We have used Roundup for a long time but dont necessarilry need it to grow corn. This table from Dr. Prostko list several options that give great weed control when applied at V3-V5 stage. Atrazine still needs to be in the tank. Take note because Counter can be used with some and not others.
