Post-emergent Herbicide Timing Key in Corn Production
Weed control in corn is important to profitability, but producers need to be aware of herbicide application timing, said Dr. Jourdan Bell, Texas A&M AgriLife Extension Service agronomist in Amarillo.
“We know post-emergent herbicide applications are necessary for season-long weed control,” Bell said. “However, it is important to follow post-emergent corn herbicide labels, which define the latest growth stage for which herbicide applications can be made without causing crop injury.”
She said herbicide applications past the recommended growth stages can result in significant crop injury, so it is important producers understand and recognize each of the stages.
