NDSU Crop and Pest Report

South_Central ND

During the past 2 weeks (July 16 to 29), total rainfall ranged from 1.2 inches at Oakes, 0.5 to 0.6 inches at Jamestown and Linton, to less than 0.25 inch at other NDAWN (North Dakota Agricultural Weather Network) sites in the region. The regionís estimated crop daily water use on July 29: wheat (5/1 emergence) = 0.06-0.09 inch; corn (5/15 emergence), soybean (5/22 emergence), dry bean (6/5 emergence) and sunflower (6/5 emergence) = 0.15-0.21 inch. Rainfall is needed for corn, soybean, dry bean, and sunflower but would hamper small grain harvest. Water use data is avail. at the following NDAWN website:


Small grain swathing and harvest are in progress through the region. Preliminary reports on grain yield and quality are very positive. Yield appears above average with initial reports of 45 to 60 bushel/acre wheat and 90 to 100 bushel/acre barley. Most timely-planted corn is in the silking stage and sunflower is near or at the early-flowering stage. Scab (fusarium head blight) levels appear low in early-planted wheat and barley. Leaf disease (tan spot, Septoria, and rust) continues to increase in severity in wheat that is still in the seed-development stages. Growers should be monitoring insects including grasshoppers, European corn borer in corn, soybean aphids in soybean, leafhoppers in dry bean, and the seed-damaging insects in sunflower.
