Southwest ND

Measurable rainfall this past week occurred primarily in the Beach, Dickinson, Hazen, Mandan and Watford City areas with a quarter of an inch or less. The big weather news this past week was wind with gusts measured at 40 to 53 mph by NDAWN! Sustained winds kept herbicide applicators out of the field for three days. Minimum temperatures in the low 20s F and in some areas the high teens either delayed alfalfa development or in some cases alfalfa will need to initiate growth from the crown of the plant again. Tan spot has been reported on winter wheat and producers will likely include a foliar fungicide to control this disease when they apply their herbicide later this week.

Planting progress continues to feel the affect of a wet spring in the far western counties. Wheat and barley seeding is essentially complete in Morton County while Hettinger and Mercer Counties are about 80% complete on seeding, Stark County is 50%, Dunn County is 40% and Bowman County is about 30%. In the Rhame area and south of Belfield, producers have been having difficulty getting into the field. Canola and pea seeding is complete in many areas. Canola seeded in mid-April is beginning to emerge. Spring wheat that was seeded prior to mid-April has progressed to the 1 to 2-leaf stage. Over the weekend, soil conditions warmed and corn that was seeded a week ago or earlier is beginning to emerge. Some producers have applied fertilizer to tame pastures to take advantage of early season moisture.

As weather conditions improve this week, in-crop foliar herbicide/ fungicide applications to winter wheat should be well underway by the end of the week. Some of the mustards are beginning to bolt. Producers will be pushing to complete seeding wheat and moving into planting corn and flax by the end of this week.

South-Central ND

During the last week (May 3-9), the region received 0.01 (Carrington and Tappen) to 0.39 (Oakes) inches of rain, based on NDAWN (North Dakota Agricultural Weather Network). The rain is hindering timely cool-season crop and corn planting. The majority of wheat and barley acres have been planted in the region. Growers also are trying to complete planting of canola, flax and field pea. Corn planting continues with probably 30 to 50% of acres completed. Soybean planting has begun this week. Alfalfa and winter wheat fields generally appear in good condition. Annual weeds currently emerging include foxtail, common cocklebur, pigweed, common ragweed and volunteer soybean.

Crop Management Field School Scheduled June 22 at Carrington

A crop management field school will be offered Thursday, June 22, from 9 a.m. to 4:30 p.m. at the NDSU Carrington Research Extension Center. The school will provide hands-on training on crop pest and soil management using research and demonstration plots. Field sessions include:

  • Weed identification - identify more than 60 living weed exhibits and review biology and control
  • Herbicide mode-of-action - identify herbicide classes by examining crop and weed injury symptoms
  • Wheat disease management - review disease forecasting and fungicide use strategies
  • Insect management - review of current insect concerns in oilseed and grass crops
  • Soil pits - below ground examination to explain above-ground crop growth
  • For details and pre-registration information, contact the Carrington Center at (701) 652-2951 or see website A completed pre-registration form and $50 fee is requested by June 19 ($75 after June 19). The school will provide participating Certified Crop Advisers with 4.5 IPM and 1.5 soil and water management continuing education units.
