Weed Management

When planting  corn it is highly recommended that you have a good weed management plan.

Keep in mind that our seed corn is open pollinated and non-gmo so if  glyphosate touches it it will die.

If using herbicides always read and follow the label! :

Foxtails are usually the biggest challenge for open pollinated corn and must be controlled early.  The S-Metolachlor and Balance Flexx will work for residual foxtail control.  S-Metolacchlor will not kill any foxtail that is emerged.  

Read the labels and consider your next crop when choosing herbicides.

No Herbicide:

Preplant:  Tillage
