NDSU Crop and Pest Report

FROM AROUND THE STATE

South-Central ND

During May 8 to 14, area moisture (rain and snow) amounts ranged from 1.2 inches at McLeod to 0.12 inches at Linton as recorded at NDAWN sites. Most of the region received about 0.5 inches or more of moisture. Black soil temperatures at the 4-inch depth ranged from the upper 40's to low 50's F on May 14. Fieldwork should be in progress throughout this week of May 13.

There continues to be a wide spread of seeding progress between counties north of I-94 compared to counties near the South Dakota border, as of May 15. In the southern counties, small grain seeding is nearly complete and corn should be finished at week’s end. Small grain fields seeded in April generally have emerged. Soybean planting is in progress and dry bean and sunflower planting will start soon. In Eddy, Foster, Sheridan and Wells counties, 25% or less of small grain, canola, and flax seeding is complete. General concern exists with timely seeding of corn and cool-season crops. This may mean a likely increase in soybean and sunflower acres for this northern region. Wild oat and other early-season weeds are emerging.

Southwestern ND

Precipitation in the form of snow and rain was received on May 6 – 9 of last week. Total moisture content was 0.91 inches which kept producers out of the field until May 12 in the Dickinson-Taylor-Richardton area. Since Sunday, planting has been progressing rapidly in most counties in the southwest portion of the state. In areas such as Hettinger, Scranton, and Bowman, several producers are reporting that small grain planting is essentially complete. Dunn and Oliver Counties are reporting that approximately 15% and 30%, respectively, of the wheat acreage has been planted as of May 14.

Wheat, barley, pea, and canola seeded earlier last month are beginning or completely emerged. Some wheat and barley fields have one complete leaf formed. Most canola that is emerged is in the cotyledon stage though the first true leaf in some plantings is beginning to show. Dormant-seeded canola at the Dickinson Research Extension Center is showing severe cold as well as flea beetle injury. The combination of these two stresses is taking a toll on dormant-seeded canola. To date, little injury from flea beetle has been found on the spring seeded canola in the Dickinson area but further south at Hettinger flea beetles and pitting have been observed.

Some fields that would have been planted to canola had producers been able to get into the field in April for the first week of May will now be seeded to sunflower. Canola date of planting data from Hettinger Research Extension Center indicates delaying seeding canola from April 1 to May 1 will cause a 68% reduction in yield. In some years (one year in five) the reduction isn’t that steep. However, southwest canola producers should have had seed in the ground by May 1. Southwest producers thinking of planting this late (May 15) would be better off returning seed to the dealer and planting sunflower.

Alfalfa is about two inches in height in established plantings. Sweet clover weevils are beginning to feed on sweet clover.
