Northwest ND (05/14/20)

Information from the Northwest region of North Dakota.

Despite a cold front coming through late last week, planting continues in Northwest ND. Warm temperatures in the first half of last week gave way to highs in the 40’s and lows in the 20’s over the weekend. Scattered thundershowers also moved through Friday, May 8th overnight in to Saturday. These storms did not drop a lot of rain, however, with most NDAWN stations recording 0.1-0.25”. The 7-day forecast predicts a warm up mid-week with high’s returning to the 60’s and 70’s through next week.

Winter wheat at the Williston REC is tillering with stands showing 2-4 tillers. Peas and small grains planted two weeks ago are starting to emerge. Crops are emerging slowly with the cooler than normal temperatures. Cool temperatures don’t seem to be slowing down the weeds much as I’ve seen some sizeable tansy mustard around and shepherd’s purse starting to flower. Now would be a good time to control emerged winter annual weeds like horseweed and narrow leaf hawksbeard prior to planting. As a reminder, we do have glyphosate resistant horseweed in the area, so growers are advised to use more than just glyphosate in their burndown. 2,4-D can be used in front of barley and wheat while Sharpen is a good choice before pulse crops.
