Several factors in the normal process of germination can work together to result in corn leafing out prior to emergence. Understanding the most likely causes can potentially help avoid leafing out prior to emergence in future crops. Symptoms of chilling injury may be compounded by stresses such as herbicide injury, disease, or soil crusting. Farmers can manage fields to avoid chilling injury by planting during a favorable forecast and should follow up with scouting for seedling health and emergence success.
