Peak nitrogen uptake times differ from hybrid to hybrid. Hybrids that flower relatively early for their maturity require peak N earlier, hybrids that flower average for their maturity need N consistently throughout the growing season, and those that flower late for their maturity require peak N later in the growing season.

Northern Corn Leaf Blight (NC Leaf Blight):

This disease is prevalent in the northern half of the U.S. following warm, moist weather and heavy dews. Diseased areas have long, elliptical, tan lesions, and may be up to six inches long. Lower leaves show symptoms first. In severe cases, the plant may turn grayish green and die prematurely. This fungus also overwinters in corn debris.
