Storms can damage a corn crop in many ways. After severe weather, specifically after receiving hail, the best thing to do is examine the growing point of the plant based on the stage, making sure it’s still intact. The growing point remains below the soil until around the B6 growth stage, so if you receive hail on a corn crop prior to that stage, even severe hail, you should still be able to recover from that. The most prevalent damage is going to be the leaf damage you see. From there, you should wait about five days, take stand counts, and examine plants and the growing points to see if they are still viable.
