South-Central ND

During July 24-30, NDAWN sites receiving 0.75 to 1.25 inches of rain included Oakes, Jamestown, Edgeley, Wishek, and Linton while other areas in south-central ND received 0 to 0.45 of an inch. Daily water use of crops is high. As an example, estimated daily crop water use on July 30 for corn (May 15 emergence), soybean (May 29 emergence), and sunflower (June 5 emergence) was about 0.3 to 0.35 inches. Timely and adequate amounts of rain during the next several weeks will be important to maintain the currently good yield potential of corn and beans throughout the region.

Winter wheat and barley harvest currently is in progress south of I94 and spring wheat harvest will soon be starting. Canola swathing is beginning. Throughout the region, corn is silking, soybean are forming pods, and sunflower are beginning to bloom. Haying continues including CRP fields and the second alfalfa harvest.

Growers should continue monitoring and treating (if needed) late-season crops for grasshoppers. Soybean aphid have been recently found at the Carrington Research Extension Center at very low levels. Growers should continue to monitor their soybean fields for this insect. European corn borer levels currently appear low in the Carrington area, but insecticide treatments have been made in Ransom County. Leaf rust appears to be the most economic disease affecting late-planted wheat north of I94. Fusarium head blight (scab) can be readily found in northern-area wheat fields. Dry bean growers should continue to monitor for rust especially if susceptible varieties are in production. The red sunflower weevil is present and sunflower fields should be monitored for the weevil and banded sunflower moth. Late-season weed growth is common in small grain and flax.
