While planting was a bit delayed for Herman, Minnesota farmers, a lot of crop was put into the ground in mid-May. “I didn’t think we’d have any knee-high corn by July 4, but a lot of it chest high,” says Scott Libbesmeier of Lakeside Seeds and Insurance. “I think we’re pushing towards an above-average crop at this point.” A critical factor in crop development are growing degree days. Pioneer field agronomist Clyde Tiffany says GDUs have shifted a lot over the last two weeks with warmer temperatures. “For a May 15 planting date, there are about 772 GDUs accumulated. We really aren’t as far off as people feared.” Tiffany adds there are several agronomic elements to be monitoring right now. Farmers should be scouting for corn borer and root worm, as well as considering side dressing options. Watch the Pioneer Agronomy Update on Facebook.
