Hail pounded various parts of Iowa over the last two weeks. Storm systems continue to march aggressively across the state. Shredded, twisted corn lies in their paths (Figure 1). Corn across the state ranges from 6th to perhaps the 10th leaf stage. That means that corn growing points extend above the ground. Damage to the growing point compromises recovery and yield.
