South-Central ND


During June 12 to 18, area rainfall ranged from 0.6 inches at McLeod and McHenry to 0.04 inches at Jamestown as recorded at NDAWN sites. Estimated daily crop water use on June 18 in south-central ND: corn (May 15 emergence) = 0.13-0.16 inches; wheat (May 15 emergence) = 0.19-0.23 inches; soybean (May 29 emergence) = 0.08-0.10 inches; and sunflower (June 5 emergence) = 0.09-0.11 inches. Additional rainfall is needed throughout the region, especially in counties south of I94.


Some sunflower and annual forages are still being  planted. Crop conditions vary, depending on amount of recently-received moisture. In southern counties, early-seeded small grain generally is short (< 12 inches in height) and is heading. Farmers are debating whether to add additional imputs (e.g. weed control) and in extreme cases, whether to harvest wheat and barley for grain. North of Highway 200, crop conditions generally are good. Pasture and hayland conditions continue to be disappointing, especially in southern counties. Hay harvest has begun.


Herbicide application continues in late-seeded small grain, as well as in corn, flax and beans. Cutworms are reducing bean and sunflower stands in scattered fields. Sunflower growers should be monitoring for cutworm and sunflower beetle feeding. Tan spot is becoming common in wheat in areas that have received significant rain during the past couple of weeks. According to the NDSU small grain disease forecasting model, conditions favorable for tan spot infection were present 4 of 9 days during June 5-17 at Carrington.
