South-Central/Southeast ND (06/18/20)

Information from the South Central/Southeast region of North Dakota.

According to NDAWN, rainfall during June 1-15 ranged from 0.2 inch (Jamestown) to 3.8 inches (Oakes), with the Carrington Research Extension Center (CREC) receiving 0.3 inch. While subsoil moisture is adequate, most of this region, except the southeast, would welcome rain to rewet the topsoil. This would provide soil conditions to help adequately establish late-planted row crops and activate PRE herbicides. High wind, along with warm temperatures, has contributed to the dry topsoil and hampered timely application of POST herbicides. For example, during June 13-15, the region’s daily average wind speed ranged from 7-24 mph with maximum wind speed ranging from 22-47 mph.

Alfalfa harvest is in progress. Winter cereals generally are in the flowering to early seed formation stages. Barley and spring wheat crops seeded late April are near or at heading. Small grain in areas with limited topsoil moisture, such as the CREC, have short plants and reduced yield potential. Late-April planted corn has 6 leaves (V6 stage) and soybean is in the third trifoliate (V3) stage. Late-season row crop planting is essentially complete.

Weed control is the most challenging crop protection problem, while minimal disease or insect problems have been reported or observed.
