There is still time to guess what is going on with corn. Below is another image of field corn being affected by the same cause. This image actually is a two-fer, there is slug injury on the bottom leaves, but slugs do not cause the whorl wilting. This plant will not recover. Less severe injury will show up as the yellowing in last week’s images.
