North Central ND (06/14/18)

Information from the North Central region of North Dakota

Over the last week, a wide area of North Central North Dakota received decent amounts of precipitation.  Minot received about 1.12”, Bottineau 1.07”, Crosby 0.69”, Garrison 1.32”, and Rugby 0.45” of precipitation. Precipitation, even possible severe weather, remains part of the short term forecast. Soil temperatures (bare) appear to be holding steady at most NDAWN stations in the North Central region in the upper-60 degree range (NCREC/Minot - 70˚F, Bottineau - 66˚F; Garrison - 70˚F; Rugby - 67˚F). At the current moment, when weather permits, growers appear to be spraying crops throughout much of the region as planting has finally wrapped up.

Populations of canola flea beetle appear to be decreasing across the region as we move deeper into the month of June. That is good news as some growers in the region were having to step up scouting programs. With that said, growers should continue to scout for flea beetles through about the 6th leaf stage in canola. Additionally, the North Central scout has found some minor populations of grasshoppers in the area.  Scouting for grasshopper nymphs should continue through the month of June.  Always inspect ditches and field edges for nymphs.  The ‘threatening’ rating is considered the action threshold and is advised whenever 50-75 nymphs per square yard are being observed in adjacent non-crop areas or 30-45 nymphs per square yard within the field. Growers can use a 15 inch diameter sweep net, taking four 180 degree sweeps to equal a square yard estimate. 

Often times, wet weather can lead to some disease issues.  Some ascochyta infected field peas have been identified in the northwestern part of North Dakota, so scouting in the north central region is suggested. Additionally, some photos of wind and hail damage have come into my office in soybean, pulses, and canola – many of which were from the Kenmare, ND area.
