North Central ND (07/29/21)

Body

After some relief a week ago, the region returned to a dryer, warmer pattern in the north central region of the state. Brief hit and miss popcorn showers were observed across the region over the last seven days. The following are the latest precipitation reports as observed by area NDAWN stations over the last week (beginning July 19th): Minot: 0.07” (NCREC: 0.12”); Bottineau: 0.00”; Garrison: 0.94”; Karlsruhe: 0.22”; Mohall: 0.00”; Plaza: 0.14”; and Rugby: 0.00”. Bare soil temperature at the NCREC is observed at 83 degrees F.

It has been amazing to see so many friendly faces over the last two weeks with all the REC and off station field days underway. They were a complete success – thanks to all who came out to participate in your local field tours. Phone calls have dropped off just a little bit into the NCREC Crop Protection Office. Grasshopper calls continue to be the leading concern with localized spots of higher grasshopper numbers. Please keep in mind the importance of scouting during this time and reflect on the two different possible thresholds for grasshoppers in adults – border threshold (21-40 per square yard) and an in-field threshold (8-14 per square yard). If thresholds are met, control may be required in some circumstances. Some grasshopper nymphs are still observed in the area. Aphids are still being found in area small grains, however, due to advancing staging of small grains, aphids are no longer leading to damage.

Crop harvest of small grains and pulses are slow in the region but expected to increase by the end of the week and into next week. As expected, the crop yield reported by producers is low due to drought conditions in the region. Corn fields are highly impacted by drought, with most fields found in the VT stage with some fields observed in the R1 stage (Figure 1). Last week the Balfour area was affected by hail causing severe damage in corn fields and small grains. Soybeans are observed in R2 stages and shows signs of drought stress. Flax is observed in stage 10 to 12, but there are farmers reporting that they will have to harvest flax later this week. Canola is observed in the 4.3 stages to 5.1. Sunflowers are found ranging from V12-R2 stages with a few fields under R3 and R4. Several producers in the region are seeking information regarding the management of saline soils and as expected, the drought conditions make the saline spots more visible and sometimes larger than what farmers were expecting.
