As producers squeezed in their corn planting between storms this spring, corn seeds experienced very wet conditions in many cases, and emergence problems are being reported widely by extension field specialists and seed company agronomists. The Plant Disease Clinic also has received several samples of corn seedlings with disease problems. The stand problems are generally worse in the southern part of the state, except in local areas where heavy rain washed out fields or caused flooding. Iowa Agricultural Statistics reported on June 1 that 6 percent of the corn acreage will be replanted due to disease, flooding, or crusting and I expect this number will ultimately be even higher.
