With the Environmental Protection Agency decision on dicamba, changes were made to the Federal label. North Dakota Agricultural Weather Network Interim Director Daryl Ritchison says one key change to the label supports meteorological data. “The strongest inversions tend to occur in the evenings. Sometimes the strongest occur two hours before sunset,” says Ritchison. “One of the big changes was the move to two hours instead of one. Based on NDAWN data gathered over the past couple years, I think that was a good move.” There is also a 45-day application restriction after planting for soybeans. Ritchison is curious if North Dakota will add their own day restriction beyond the Federal label.
