South-Central ND

During the past two-week period (June 27-July 10), the region received rain ranging from 0.3 inches at Tappen to 1.7 inches at Streeter, based on NDAWN (North Dakota Agricultural Weather Network). The rain was welcome for the row crops, which are approaching or in early reproductive stages. Recent reports of hail damage are from southern Emmons County due to a July 9 storm.

Cool-season crops continue to have good to excellent yield potential. Winter wheat harvest should start the week of July 16 in southern counties and barley harvest will follow. Most spring wheat is in the milk to dough stages. Early-planted corn is beginning to tassel. Currently, the regionís accumulated corn growing degree days are similar to or ahead of the long-term average (range of 0 to 225 units), depending on location and planting dates. Soybean are flowering (R1-2 growth stages). Sunflower is in the reproductive stage (R1) and will be flowering during early August. Spring wheat foliar disease is becoming prevalent in varieties susceptible to leaf rust and other leafspot diseases. Currently, scab symptoms are minimal in spring wheat and we hope this continues during this final period of seed fill. White heads caused by the wheat stem maggot are prominently displayed in the region but generally at low incidence. Our row crops are in good to excellent condition. Soybean growers need to be monitoring for soybean aphid during the next month.
