I would agree that most fields do not have a mold issue, but corn growers need to pay attention if they see ear molds developing. Moldy corn will always yield less because mold feeds on the starches in the kernel reducing test weights and dry matter..
If you are a livestock producer, harvest and dry the crop as quickly as possible. If you have the flexibility, keep your cleanest fields for feed and sell the rest on the cash market. Blending grain is a tactic that can reduce problems because it is the toxin amount in the finished ration that determines livestock performance.
Going forward Pioneer continues to screen genetics for gibberella mold tolerance. P9754 has been advanced due to outstanding tolerance to ear mold infection.
