Some rain continued to be observed in the area over the past week. Some areas across the City of Minot received 1-3 inches; however, much of the significant rain hugged the area immediately around and throughout the city. Some hail and gusty winds were also observed in the area. With that in mind, some regions experienced much smaller precipitation amounts in the area. Here are some quick precipitation reports as observed by area NDAWN stations over the last week (beginning July 12th): Minot: 1.19” (NCREC: 1.31”); Bottineau: 0.22”; Garrison: 0.00”; Karlsruhe: 0.17”; Mohall: 0.17”; Plaza: 0.07”; and Rugby: 0.01”. Bare soil temperature at the NCREC is observed at 84 degrees F.

Grasshopper calls continued to come into the NCREC. On Monday, TJ was in the Bottineau and Renville County areas and observed increased populations of adults. Please keep in mind the importance of scouting during this time. Also, reflect on two different possible thresholds for grasshoppers – both a border threshold (21-40 per square yard) and an in-field threshold (8-14 per square yard) to determine if control is needed. Some grasshopper nymphs are still observed in the area. Accumulated growing degree day thresholds for wheat midge have surpassed the 2000-degree day mark, meaning action is no longer required in area wheat fields if thresholds had been met.

Crop harvest has started in the region. Some small grains, field peas and other pulses are being harvested. Although we had rain in the past couple of days, the rain was not enough to alleviate drought stress in the crops, especially for corn and soybeans. Field corn is showing signs of curling and drought stress. Several fields of corn are observed in the VT stage. Soybeans are found in R2 stages and shows additionally signs of drought and heat stress. Flax is found in field from stage 10 to 12, but there are farmers reporting that they will have flax to harvest later this week. Canola is found in the 4.3 stage to 5.1. Additionally, sunflowers range from the V8 to V12 stages.
