South-Central ND

    Total rainfall as recorded at NDAWN sites in south-central ND during July 26 to August 1 was
less than a 0.10 inch. The lack of rain has been timely for small grain and hay harvest. Warm-season
crop growth and condition has been excellent with warm days and nights, and with good stored soil
moisture levels. On August 1, estimated daily water use ranged from 0.27 to 0.33 inches for corn
emerged May 15, soybean and dry bean emerged May 29, and sunflower emerged June 5.

    Winter cereal and barley harvest is nearing completion while spring wheat harvest is in progress
south of I-94. Initial reports from Ransom County include barley yielding 60-70 bushels/acre and
spring wheat 50-60 bushels/acre with favorable quality. Late-planted barley appears to have lower
yield and quality. Barley swathing and harvest, and canola swathing continue north of I-94. Initial
reports from Eddy and Wells counties indicate average barley yield and feed quality. Across the region,
flax fields are turning color, grain corn is tasseling or beyond, soybean are forming pods (R3-R4 stages),
and sunflower are in bloom.

    Common root rot, leaf disease, and scab reduced small grain yield and quality across the region.
Sclerotinia can be readily found in canola. After swathing, canola stubble should be examined to
determine incidence levels of the disease to estimate yield loss and for future rotation plans. The
recent dry weather has lessened concern of white mold in beans. European corn borer levels generally
appear low in the region. Sunflower growers should continue to monitor for banded sunflower moth
and seed weevil. Pre-harvest herbicide application is a common practice in wheat.
