Beginning this time last year the droning of airplanes could be heard in Iowa as acre upon acre of corn was sprayed with fungicides. Today the skies are quiet. Why? The corn crop is two to three weeks behind in crop development compared with last year, a result of the cool and very wet start to the growing season. Across most of Iowa we will be lucky if the corn really is “knee high by the 4th July.” Last year corn was starting to tassel across the state; this year tasseling will likely occur sometime in mid-July.
