North Central ND (09/08/21)


The dry pattern persists in the region. However, last week we observed rainfall in North Central region. Here are the latest precipitation reports as observed by area NDAWN stations over the last two week (beginning August 10th): Minot: 1.36” (NCREC: 0.11”); Bottineau: 2.61”; Garrison: 0.97”; Karlsruhe: 2.89”; Mohall: 2.29”; Plaza: 1.17”; and Rugby: 4.21”. Bare soil temperature at the NCREC is observed at 73 degrees F.

Grasshopper calls are dropping but continue to be the leading entomology concern with localized spots of higher numbers in the region. Please keep in mind your economic thresholds for grasshopper 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. As small grains, pulses, and canola continue to dry down or be harvested, grasshopper populations will begin to move to the later maturing crops. At the current moment, I have taken some two-spotted spider mite calls from area gardeners, but still haven’t heard of any populations in area crops.

All the small grains are approaching to the complete harvested. The yields reported by producers are very low compared to the yields in normal years and in some cases the wheat yield is found 70% below the normal year. Pulse crops are mostly harvested in the region. We are seeing his year an increase of standing harvest canola. Soybean fields are mostly at the R-5 stage with a few fields up to the R-7 stage. Sunflowers are nearing the R-6 to R-7 stage with a few fields still playing catchup in the R-4 to R-5 stages. Most of the corn found in the region are at R-3 to R-5 and we are seeing a lot of drought stressed corn being harvested as forage.
