During the past week, leaf diseases have become noticeable on corn scattered throughout the state. Field specialists from several areas reported anthracnose is common. In addition, I have seen eyespot and common rust in central and southeastern Iowa. Gray leaf spot is showing up in some inbreds in our research plots in eastern Iowa.
