South-Central ND

The geographic area covered by this report includes a northern border of Eddy County to Sheridan County southward to Emmons County through Sargent County. During the past week (May 1-7), most of the region received a ‘million-dollar rain’, ranging from 0.7 to 2.2 inches, based on NDAWN (North Dakota Agricultural Weather Network). However, Barnes, LaMoure, Ransom, Dickey and Sargent counties received rainfall ranging up to 4 to 8 inches.

Winter wheat fields generally have adequate plant density and are actively tillering.

Alfalfa appears in good condition. Seeding of spring wheat and barley acres will essentially be complete by May 12. Fields seeded in April are in the 1- to 2-leaf stage of growth. As of May 8, 25 to 50 percent of corn acres have been planted. This week’s planting emphasis will be on corn as soil conditions allow planting to resume. Soybean planting also will begin this week.

Southwest ND

Rainfall this past weekend kept producers out of the field for at least the first couple of days of this week and probably will keep them out of some fields for at least two more days. Rainfall totals at the NDAWN sites in southwest North Dakota for the week ranged from 0.71 inches at Mott to 1.95 inches at Watford City. Reports of heavier rainfall of up to 2.25 inches at other locations have been received. This was a well timed precipitation event for getting spring seeded crops off to a good start. Prior to this past weekend’s rain, early no-till seeded wheat and barley were beginning to emerge. Precipitation during the time period of November through March was nearly an inch less than normal. Early April snow at Dickinson and showers during the remaining part of that month brought April’s precipitation to within 0.01 of an inch of normal or 1.42 inches. , Where soils were bare from tillage, extreme wind last week caused severe erosion exposing seed in some areas of the field and burying seed deeper in other parts of the field.

Winter wheat growth is excellent but there is some concern about early season tan spot on the crop. Early seed spring wheat, barley, canola and corn that was seeded at the end of April has emerged. Soil temperatures have been favorable for germination and emergence. Alfalfa development is progressing well with plant height at about 4 to 8 inches.

Cutworms were found in winter and spring wheat fields this past week in the Beach and Dickinson area but not at economically damaging levels. This past fall the cutworm moth trap network caught a few months as they migrated to fields to lay eggs. However, trap catches indicated a medium or high risk for injury from this pest for this spring. However, since trap locations are few and far between there is always a possibility that last fall that moths could have avoided the traps and found a home to lay eggs in your field. Be sure to scout areas where crop stand appears to be diminishing or slow to emerge. Additional information on the cutworm trap survey can be found at Click on Maps.
