In Iowa, every planting season has different seedling diseases. In the last two planting seasons, there were fewer spring rains compared with this year, and seedling diseases were not a problem. Because of the frequent spring rains this year, we have less early-planted soybean and more fields planted in mid-May or later. Reports and samples of seedling diseases also are later this year.
