North Central ND (06/16/16)

Information from the North Central region of North Dakota.

Some welcome precipitation fell over the last seven days. Rainfall amounts were consistently over a 1” around the North Central Region: Minot: 1.45”, Rugby: 1.20”, Berthold: 1.15”, and Mohall: 1.13” (June 5th - June 12th). Forecasts call for additional precipitation in the upcoming week.

Several reports of wheat streak mosaic virus has been observed in the North Central region. This should highlight the importance of crop rotation and eliminating green bridge post-harvest as a preventative measure to curve movement of the wheat curl mite. Rotating from cereals to broadleaf crops such as alfalfa, peas, sunflowers, or canola could help avoid disease outbreaks. As winter wheat heads begin to emerge, plan to kill off green bridge post-harvest later this season.

In canola, flea beetles (Crucifer and Striped) have been observed in growing numbers and foliar application of insecticides may be needed. Growers should scout fields regularly for flea beetle damage. Additionally, small populations of cereal aphids (English Grain Aphid and Bird Cherry Oat Aphid) have been found in parts of Ward and McHenry Counties. Although populations were not at economic thresholds, this highlights the importance of scouting in area fields.
