North Central ND (06/03/21)

Information from the North Central region of North Dakota

Despite the rain observed over the weekend, it only offered partial relief for the North Central region. Although the rain was timely, high winds played an important role to dry the topsoil, especially in areas with low soil cover by plant residues. Hit-and-miss showers were a common scene across the region with some farmers wrapping up planting activities. In general, area crops in the field are in good development (Figure 1). Last week, a noticeable frost was experienced in some areas of the state. In our region, information was received about frost damage in canola (Figure 1). The NCREC did not observe frost damage in crops already planted. The damage caused by frost on crops depends on several factors, such as crop, crop stage, duration of the frost among others. Some spray activities were seen in the region; however, the windy conditions in the past week made it difficult to find a proper time frame for spraying applications. Here are some quick precipitation reports as observed by area NDAWN stations over the last week (beginning May 25th): Minot: 0.15”; Bottineau: 0.05”; Garrison: 0.11”; Karlsruhe: 0.20”; Mohall: 0.22”; Plaza: 0.13”; and Rugby: 0.07”. Additionally, the bare soil temperature at the NCREC is observed at 69 degrees F.

Canola flea beetle activity has been fairly low so far during the 2021 growing season around the Minot area. This is likely due to cooler overnight temperatures experienced over the last 7-10 days. However, a warmer forecast lies ahead. Some quick observations at the NCREC saw increased flea beetle activity Tuesday morning, especially in canola not protected with a seed treatment. Similar observations have been made in some area gardens. For more information on canola flea beetle, please refer to the May 20th addition of the Crop & Pest Report.
