After a slow start, corn seedling problems have become evident in many fields during the past couple of weeks. With much of the corn now out of the "seedling" stage at V5 or higher, those plants that are not thriving have become obvious. On most of the samples that I have seen, the mesocotyl tissue has been rotted to some extent, either mildly or severely. This condition has resulted in poor growth or death of the plants. On the surviving seedlings, nodal roots have developed and may be able to pull the plants through, although these stunted plants are of questionable value.
