South-Central ND (07/26/18)

Information from the South Central region of North Dakota.

The region’s NDAWN station data indicate rain during July 1-23 ranged from 0.5 inch (Harvey) to 7.4 inches (Oakes), with the Carrington REC (CREC) receiving 2.5 inches. While soil moisture is generally adequate, our crops are using significant moisture. For example, NDAWN data indicates that corn which emerged on May 15 used about 0.2 inch of water per day during July 17-23.

Harvest has begun for winter cereals, and barley fields are at maturity, with harvest soon to start. Field pea and HRS wheat are nearing or are at physiological maturity. Corn planted during the first week of May is in the blister stage (R2). Based on NDAWN growing degree day units (GDDU) accumulated from May 1 planting date through July 23, the region’s corn has accumulated 1340 GDDUs (Wishek) to 1550 GDDUs (Oakes), which continues to be 1-2 weeks ahead of the long-term average for the same period. Soybean and dry bean are in pod to early seed development stages. Yellow is beginning to show in sunflower fields (R5 stage).

Incidence of wheat stem maggot damage is up, and scab levels are low for the southeast quadrant of ND. See NDSU IPM website for crop survey data: www.ag.ndsu.edu/ndipm.

Bacterial disease in dry bean (see picture) and corn (Goss’ Wilt) plus potential for white mold in bean crops continue to threaten dry bean seed yield and quality.
