South-Central/Southeast ND (07/23/20)

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

July has provided an array of weather challenges for our crops including variable rainfall and air temperatures, high winds and hail. According to NDAWN, the region’s rainfall during May 1-July 20 ranges from 3.5 inches (Zeeland) to 12.5 inches (Oakes), with the Carrington Research Extension Center (CREC) receiving 6.2 inches. The region, with the exception of southwest counties, has received adequate rain to aid seed development of spring-seeded small grain and maintain yield potential of row crops.

Winter cereal harvest has begun. Early seeded barley and spring wheat are nearing maturity. Corn growth stages range from late vegetative, with many fields showing tassels (VT) to blister stages (R2). Timely planted soybean and late-May planted dry bean are in the pod to early seed development stages. Sunflower will soon begin flowering while canola and flax have essentially moved past flowering and developing seed.

The generally frequent July rains providing abundant soil moisture plus recent moderate air temperatures are increasing risk of white mold in susceptible broadleaf crops. Also, bacterial disease is easily found in soybean and dry bean due to the wet weather combined with wind and hail.
