Planting Interval of Corn after Previous Year's Soybean Herbicides

April 21, 2017
Corn-soybean is the most common cropping system in eastern Nebraska. While corn growers are getting ready for planting this season, it is important to pay attention to the planting interval of herbicides applied the previous year in soybean. Certain soybean herbicides have relatively longer planting intervals for corn, especially if they are applied post-emergence in soybean. This is particularly important because soybean planting was late last year in much of Nebraska due to May rains. This caused postemergence herbicides to be applied later in the season than they might normally be, making it important that you pay attention to the planting interval.
