As we enter into the post-pollination phase of the season, many corn diseases will accelerate their development. So far, leaf diseases have not been very severe, largely because of the dry weather. Common rust is evident in many fields but only at very low levels, and traces of gray leaf spot and eyespot can be found. Gray leaf spot has the potential to increase rapidly during the post-pollination period, even when rainfall is not plentiful.
